Сдвиньте макет вверх снизу экрана

Question 1

У меня есть макет, скрытый от просмотра. При нажатии кнопки я хочу, чтобы она скользила вверх снизу, подталкивая все содержимое экрана вверх, очень похоже на то, как WhatsApp показывает панель смайлов на экране чата.

Я видел SlidingDrawer, мне это не подходит. Для этого требуется изображение в качестве ручки, которая отображается в центре экрана, я этого не хочу. Он также скользит по существующему содержимому экрана, я ищу способ переместить существующий контент вверх.

Обновление 1:

Я попробовал использовать анимацию, предложенную Санкет Качхела. Но скрытый макет никогда не отображается. Вот код.

Макет (activity_main.xml):

<RelativeLayout
    android:id="@+id/main_screen"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" 
        android:layout_alignParentTop="true"/>

     <TextView
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:text="@string/hello_world" 
       android:layout_centerInParent="true"/>

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Slide up / down"
        android:layout_alignParentBottom="true" 
        android:onClick="slideUpDown"/>

</RelativeLayout>

<RelativeLayout
    android:id="@+id/hidden_panel"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" 
    android:layout_below="@id/main_screen">

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/app_name" />

</RelativeLayout>

Активность (MainActivity.java):

package com.example.slideuplayout;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.view.ViewGroup;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;

public class MainActivity extends Activity {

private ViewGroup hiddenPanel;
private boolean isPanelShown;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    hiddenPanel = (ViewGroup)findViewById(R.id.hidden_panel);
    hiddenPanel.setVisibility(View.INVISIBLE);
    isPanelShown = false;
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

public void slideUpDown(final View view) {
    if(!isPanelShown) {
        // Show the panel
        Animation bottomUp = AnimationUtils.loadAnimation(this,
                R.anim.bottom_up);

        hiddenPanel.startAnimation(bottomUp);
        hiddenPanel.setVisibility(View.VISIBLE);
        isPanelShown = true;
    }
    else {
        // Hide the Panel
        Animation bottomDown = AnimationUtils.loadAnimation(this,
                R.anim.bottom_down);

        hiddenPanel.startAnimation(bottomDown);
        hiddenPanel.setVisibility(View.INVISIBLE);
        isPanelShown = false;
    }
}

}

Анимации:

bottom_up.xml:

<?xml version="1.0" encoding="utf-8"?>
 <set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate 
       android:fromYDelta="75%p"
       android:toYDelta="0%p"
       android:fillAfter="true"
       android:duration="500" />
</set>

bottom_down.xml:

<?xml version="1.0" encoding="utf-8"?>
 <set xmlns:android="http://schemas.android.com/apk/res/android">
<translate 
    android:fromYDelta="0%p" 
    android:toYDelta="100%p" 
    android:fillAfter="true"
    android:interpolator="@android:anim/linear_interpolator"
    android:duration="500" />
</set>

Any ideas how this can be done ?

Thanks.

Question 2

Use these animations:

bottom_up.xml

<?xml version="1.0" encoding="utf-8"?>
 <set xmlns:android="http://schemas.android.com/apk/res/android">
   <translate android:fromYDelta="75%p" android:toYDelta="0%p" 
    android:fillAfter="true"
 android:duration="500"/>
</set>

bottom_down.xml

 <?xml version="1.0" encoding="utf-8"?>
 <set xmlns:android="http://schemas.android.com/apk/res/android">

<translate android:fromYDelta="0%p" android:toYDelta="100%p" android:fillAfter="true"
            android:interpolator="@android:anim/linear_interpolator"
    android:duration="500" />

</set>

Use this code in your activity for hiding/animating your view:

Animation bottomUp = AnimationUtils.loadAnimation(getContext(),
            R.anim.bottom_up);
ViewGroup hiddenPanel = (ViewGroup)findViewById(R.id.hidden_panel);
hiddenPanel.startAnimation(bottomUp);
hiddenPanel.setVisibility(View.VISIBLE);

Question 3

You were close. The key is to have the hidden layout inflate to match_parent in both height and weight. Simply start it off as View.GONE. This way, using the percentage in the animators works properly.

Layout (activity_main.xml):

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/main_screen"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:text="@string/hello_world" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:text="@string/hello_world" />

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:onClick="slideUpDown"
        android:text="Slide up / down" />

    <RelativeLayout
        android:id="@+id/hidden_panel"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@android:color/white"
        android:visibility="gone" >

        <Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/app_name"
            android:layout_centerInParent="true"
            android:onClick="slideUpDown" />
    </RelativeLayout>

</RelativeLayout>

Activity (MainActivity.java):

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;

public class OffscreenActivity extends Activity {
    private View hiddenPanel;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main_activity);

        hiddenPanel = findViewById(R.id.hidden_panel);
    }

    public void slideUpDown(final View view) {
        if (!isPanelShown()) {
            // Show the panel
            Animation bottomUp = AnimationUtils.loadAnimation(this,
                    R.anim.bottom_up);

            hiddenPanel.startAnimation(bottomUp);
            hiddenPanel.setVisibility(View.VISIBLE);
        }
        else {
            // Hide the Panel
            Animation bottomDown = AnimationUtils.loadAnimation(this,
                    R.anim.bottom_down);

            hiddenPanel.startAnimation(bottomDown);
            hiddenPanel.setVisibility(View.GONE);
        }
    }

    private boolean isPanelShown() {
        return hiddenPanel.getVisibility() == View.VISIBLE;
    }

}

Only other thing I changed was in bottom_up.xml. Instead of

android:fromYDelta="75%p"

I used:

android:fromYDelta="100%p"

But that's a matter of preference, I suppose.

Question 4

You just need to add some line in your app, please find it from below link:

Show and hide a View with a slide up/down animation

Just add an animation to your layout like this:

mLayoutTab.animate()
  .translationYBy(120)
  .translationY(0)
  .setDuration(getResources().getInteger(android.R.integer.config_mediumAnimTime));

Question 5

Here is what worked in the end for me.

    root.addView(hiddenPanel);

    isPanelShown = false;
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

public void slideUpDown(final View view) {
    if(!isPanelShown) {
        // Show the panel
        mainScreen.layout(mainScreen.getLeft(),
                          mainScreen.getTop() - (screenHeight * 25/100),

                hiddenPanel.layout(mainScreen.getLeft(), mainScreen.getBottom(), mainScreen.getRight(), screenHeight);
            }
        });
        hiddenPanel.startAnimation(bottomDown);
    }
}
}

Question 6

Use this layout. If you want to animate the main view shrinking you'll need to add animation to the height of the hidden bar, buy it may be good enough to use the translate animation on the bar, and have the main view height jump instead of animate.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

<RelativeLayout
    android:id="@+id/main_screen"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:text="@string/hello_world" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:text="@string/hello_world" />

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:onClick="slideUpDown"
        android:text="Slide up / down" />
</RelativeLayout>

<RelativeLayout
    android:id="@+id/hidden_panel"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom"
    android:background="#fcc"
    android:visibility="visible" >

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/app_name" />
</RelativeLayout>

</LinearLayout>

Question 7

Ok, there are two possible approaches. The simplest - is to use a sliding menu library. It allows creating a bottom sliding menu, it can animate the top container to make bottom visible, it suports both dragging it with your finger, or animating it programmatically via button (StaticDrawer).

Harder way - if you want to use Animations, as was already suggested. With animations you must FIRST change your layouts. So try first to make your layout change to the final state without any animations whatsoever. Because it is very likely that you are not laying out your views properly in RelativeLayout, so even though you show your bottom view, it remains obscured by the top one. Once you achieved proper layout change - all you need to do is to is to remember translations before layout and apply translate animation AFTER layout.

Question 8

My code to make animation slide up, slide down without XML

private static ObjectAnimator createBottomUpAnimation(View view,
        AnimatorListenerAdapter listener, float distance) {
    ObjectAnimator animator = ObjectAnimator.ofFloat(view, "translationY", -distance);
//        animator.setDuration(???)
    animator.removeAllListeners();
    if (listener != null) {
        animator.addListener(listener);
    }
    return animator;
}

public static ObjectAnimator createTopDownAnimation(View view, AnimatorListenerAdapter listener,
        float distance) {
    view.setTranslationY(-distance);
    ObjectAnimator animator = ObjectAnimator.ofFloat(view, "translationY", 0);
    animator.removeAllListeners();
    if (listener != null) {
        animator.addListener(listener);
    }
    return animator;
}

Using For slide down

createTopDownAnimation(myYellowView, null, myYellowView.getHeight()).start();

For slide up

createBottomUpAnimation(myYellowView, null, myYellowView.getHeight()).start();

Question 9

Try this below code, Its very short and simple.

Question 11

You could define the mainscreen and the other screen that you want to scroll up as fragments. When the button on the mainscreen is pushed, the fragment would send a message to the activity which would then replace the mainscreen with the one that you want to scroll up and animate the replacement.

Answer 1

У меня есть макет, скрытый от просмотра. При нажатии кнопки я хочу, чтобы она скользила вверх снизу, подталкивая все содержимое экрана вверх, очень похоже на то, как WhatsApp показывает панель смайлов на экране чата.

Я видел SlidingDrawer, мне это не подходит. Для этого требуется изображение в качестве ручки, которая отображается в центре экрана, я этого не хочу. Он также скользит по существующему содержимому экрана, я ищу способ переместить существующий контент вверх.

Обновление 1:

Я попробовал использовать анимацию, предложенную Санкет Качхела. Но скрытый макет никогда не отображается. Вот код.

Макет (activity_main.xml):

<RelativeLayout
    android:id="@+id/main_screen"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" 
        android:layout_alignParentTop="true"/>

     <TextView
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:text="@string/hello_world" 
       android:layout_centerInParent="true"/>

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Slide up / down"
        android:layout_alignParentBottom="true" 
        android:onClick="slideUpDown"/>

</RelativeLayout>

<RelativeLayout
    android:id="@+id/hidden_panel"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" 
    android:layout_below="@id/main_screen">

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/app_name" />

Your layout hidden_panel might be going behind other layout. Call hiddenPanel.bringToFront() before starting animation and see if it works. Also let us know, are you getting hidden_panel view in graphical layout for activity_main.xml ?

Use these animations:

bottom_up.xml

<?xml version="1.0" encoding="utf-8"?>
 <set xmlns:android="http://schemas.android.com/apk/res/android">
   <translate android:fromYDelta="75%p" android:toYDelta="0%p" 
    android:fillAfter="true"
 android:duration="500"/>
</set>

bottom_down.xml

 <?xml version="1.0" encoding="utf-8"?>
 <set xmlns:android="http://schemas.android.com/apk/res/android">

<translate android:fromYDelta="0%p" android:toYDelta="100%p" android:fillAfter="true"
            android:interpolator="@android:anim/linear_interpolator"
    android:duration="500" />

</set>

Use this code in your activity for hiding/animating your view:

Animation bottomUp = AnimationUtils.loadAnimation(getContext(),
            R.anim.bottom_up);
ViewGroup hiddenPanel = (ViewGroup)findViewById(R.id.hidden_panel);
hiddenPanel.startAnimation(bottomUp);
hiddenPanel.setVisibility(View.VISIBLE);

Answer 13

You were close. The key is to have the hidden layout inflate to match_parent in both height and weight. Simply start it off as View.GONE. This way, using the percentage in the animators works properly.

Layout (activity_main.xml):

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/main_screen"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:text="@string/hello_world" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:text="@string/hello_world" />

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:onClick="slideUpDown"
        android:text="Slide up / down" />

    <RelativeLayout
        android:id="@+id/hidden_panel"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@android:color/white"
        android:visibility="gone" >

        <Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/app_name"
            android:layout_centerInParent="true"
            android:onClick="slideUpDown" />
    </RelativeLayout>

    }

    public void slideUpDown(final View view) {
        if (!isPanelShown()) {
            // Show the panel
            Animation bottomUp = AnimationUtils.loadAnimation(this,
                    R.anim.bottom_up);

            hiddenPanel.startAnimation(bottomUp);
            hiddenPanel.setVisibility(View.VISIBLE);
        }
        else {
            // Hide the Panel
            Animation bottomDown = AnimationUtils.loadAnimation(this,
                    R.anim.bottom_down);

            hiddenPanel.startAnimation(bottomDown);
            hiddenPanel.setVisibility(View.GONE);
        }
    }

    private boolean isPanelShown() {
        return hiddenPanel.getVisibility() == View.VISIBLE;
    }

}

Only other thing I changed was in bottom_up.xml. Instead of

android:fromYDelta="75%p"

I used:

android:fromYDelta="100%p"

But that's a matter of preference, I suppose.

You just need to add some line in your app, please find it from below link:

Show and hide a View with a slide up/down animation

Just add an animation to your layout like this:

mLayoutTab.animate()
  .translationYBy(120)
  .translationY(0)
  .setDuration(getResources().getInteger(android.R.integer.config_mediumAnimTime));

It is the parent layout encapsulating main_screen. Seems like in trying to remove the excess UI elements I ended up removing it from the code I have pasted here. It was either Linear or Relative layout.

Answer 24

Use this layout. If you want to animate the main view shrinking you'll need to add animation to the height of the hidden bar, buy it may be good enough to use the translate animation on the bar, and have the main view height jump instead of animate.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

<RelativeLayout
    android:id="@+id/main_screen"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:text="@string/hello_world" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:text="@string/hello_world" />

    <Button

        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:onClick="slideUpDown"
        android:text="Slide up / down" />

<RelativeLayout
    android:id="@+id/hidden_panel"

Answer 25

On the 'slide up' button click, I am programmatically changing the position of main_screen and the hidden panel upwards by calling the layout method, then I am calling the startAnimation on hidden view. This makes the hidden panel pop up into the place. But for some reason the button inside the panel is not showing up. The panel is empty. Any clues why the button is not showing up?

Babar

Answer 26

You should just change visibility of the hidden panel to visible. From your description, I am guessing that the button visibility was changed, or the button width/height is zero

Answer 27

Ok, there are two possible approaches. The simplest - is to use a sliding menu library. It allows creating a bottom sliding menu, it can animate the top container to make bottom visible, it suports both dragging it with your finger, or animating it programmatically via button (StaticDrawer).

Harder way - if you want to use Animations, as was already suggested. With animations you must FIRST change your layouts. So try first to make your layout change to the final state without any animations whatsoever. Because it is very likely that you are not laying out your views properly in RelativeLayout, so even though you show your bottom view, it remains obscured by the top one. Once you achieved proper layout change - all you need to do is to is to remember translations before layout and apply translate animation AFTER layout.

the button on the hidden panel was not showing up, probably because the panel was off screen. What I did was kept the layout hidden and on screen, then used the animations to put it at correct location.

I don't think SlidingMenu allows from bottom; left, right only, I believe

@wkhatch is correct, a BOTTOM SlidingMenu throws the exception: "SlidingMenu mode must be LEFT, RIGHT, or LEFT_RIGHT" which is in-line with the documentation and contrary to this answer.

My code to make animation slide up, slide down without XML

private static ObjectAnimator createBottomUpAnimation(View view,
        AnimatorListenerAdapter listener, float distance) {
    ObjectAnimator animator = ObjectAnimator.ofFloat(view, "translationY", -distance);
//        animator.setDuration(???)
    animator.removeAllListeners();
    if (listener != null) {
        animator.addListener(listener);
    }
    return animator;
}

public static ObjectAnimator createTopDownAnimation(View view, AnimatorListenerAdapter listener,
        float distance) {
    view.setTranslationY(-distance);
    ObjectAnimator animator = ObjectAnimator.ofFloat(view, "translationY", 0);
    animator.removeAllListeners();
    if (listener != null) {
        animator.addListener(listener);
    }
    return animator;
}

Using For slide down

createTopDownAnimation(myYellowView, null, myYellowView.getHeight()).start();

For slide up

createBottomUpAnimation(myYellowView, null, myYellowView.getHeight()).start();

You could define the mainscreen and the other screen that you want to scroll up as fragments. When the button on the mainscreen is pushed, the fragment would send a message to the activity which would then replace the mainscreen with the one that you want to scroll up and animate the replacement.

I just want the screen to pushed upwards by the hidden panel once it is on screen. I don't want to replace screen content / fragments. I managed to get it working with animations and layout tinkering.
