Fragment transaction animation: slide in and slide out

Question

I've check some tutorials for animate transaction between fragments. I've used this method for animation and it works:

fragmentTransaction.setCustomAnimations(android.R.anim.slide_in_left,
                android.R.anim.slide_out_right);

But I want to invert this animation: old fragment slide out to the left, and new fragment slide in to the right, but no value of R.anim file seems to be useful for my scope.

How can I do it?

Answer 1

For me the only way I was able to get rid of the white background on the animation is if I changed to a DialogFragment instead of a Fragment and added the following code:

Created the following styles:

<style name="WindowSlideInAndOutAnimation">
        <item name="android:windowEnterAnimation">@anim/slide_in_bottom</item>
        <item name="android:windowExitAnimation">@anim/slide_out_top</item>
    </style>

    <style name="AppFullScreenDialogTransparentTitleBar" parent="Theme.MaterialComponents.Light.Dialog">
        <item name="android:windowBackground">@android:color/transparent</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowIsFloating">false</item>
        <item name="colorPrimaryDark">@android:color/transparent</item>
    </style>

Then reference these styles in the dialog fragment as such:

override fun getTheme() = R.style.AppFullScreenDialogTransparentTitleBar

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        dialog?.window?.setWindowAnimations(R.style.WindowSlideInAndOutAnimation)

//rest of code on view created here
}

Then I just navigate to the fragment as normal via the navigation component (also note to change the type in the navigation xml file for the fragment to be dialog)

Answer 2

Have the same problem with white screen during transition from one fragment to another. Have navigation and animations set in action in navigation.xml.

Background in all fragments the same but white blank screen. So i set navOptions in fragment during executing transition

          //Transition options
        val options = navOptions {
            anim {
                enter = R.anim.slide_in_right
                exit = R.anim.slide_out_left
                popEnter = R.anim.slide_in_left
                popExit = R.anim.slide_out_right
            }
        }

.......................

  this.findNavController().navigate(SampleFragmentDirections.actionSampleFragmentToChartFragment(it),
                    options)

It worked for me. No white screen between transistion. Magic )

UPDATE For Android v19+ see this link via @Sandra

You can create your own animations. Place animation XML files in res > anim

enter_from_left.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:shareInterpolator="false">
  <translate 
      android:fromXDelta="-100%p" android:toXDelta="0%"
      android:fromYDelta="0%" android:toYDelta="0%"
      android:duration="@android:integer/config_mediumAnimTime"/>
</set>

enter_from_right.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:shareInterpolator="false">
  <translate
     android:fromXDelta="100%p" android:toXDelta="0%"
     android:fromYDelta="0%" android:toYDelta="0%"
     android:duration="@android:integer/config_mediumAnimTime" />
</set>

exit_to_left.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:shareInterpolator="false">
  <translate 
      android:fromXDelta="0%" android:toXDelta="-100%p"
      android:fromYDelta="0%" android:toYDelta="0%"
      android:duration="@android:integer/config_mediumAnimTime"/>
</set>

exit_to_right.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:shareInterpolator="false">
  <translate
     android:fromXDelta="0%" android:toXDelta="100%p"
     android:fromYDelta="0%" android:toYDelta="0%"
     android:duration="@android:integer/config_mediumAnimTime" />
</set>

you can change the duration to short animation time

android:duration="@android:integer/config_shortAnimTime"

or long animation time

android:duration="@android:integer/config_longAnimTime" 

USAGE (note that the order in which you call methods on the transaction matters. Add the animation before you call .replace, .commit):

FragmentTransaction transaction = supportFragmentManager.beginTransaction();
transaction.setCustomAnimations(R.anim.enter_from_right, R.anim.exit_to_left, R.anim.enter_from_left, R.anim.exit_to_right);
transaction.replace(R.id.content_frame, fragment);
transaction.addToBackStack(null);
transaction.commit();

slide_in_down.xml

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

slide_in_up.xml

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

slide_out_down.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="@android:integer/config_longAnimTime"
        android:fromYDelta="-100%"
        android:toYDelta="0"
        />
</set>

slide_out_up.xml

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

direction = down

            activity.getSupportFragmentManager()
                    .beginTransaction()
                    .setCustomAnimations(R.anim.slide_out_down, R.anim.slide_in_down)
                    .replace(R.id.container, new CardFrontFragment())
                    .commit();

direction = up

           activity.getSupportFragmentManager()
                    .beginTransaction()
                    .setCustomAnimations(R.anim.slide_in_up, R.anim.slide_out_up)
                    .replace(R.id.container, new CardFrontFragment())
                    .commit();

Answer 5

There is three way to transaction animation in fragment.

Transitions

So need to use one of the built-in Transitions, use the setTranstion() method:

getSupportFragmentManager()
        .beginTransaction()
        .setTransition( FragmentTransaction.TRANSIT_FRAGMENT_OPEN )
        .show( m_topFragment )
        .commit()

Custom Animations

You can also customize the animation by using the setCustomAnimations() method:

getSupportFragmentManager()
        .beginTransaction()
        .setCustomAnimations( R.anim.slide_up, 0, 0, R.anim.slide_down)
        .show( m_topFragment )
        .commit()

slide_up.xml

<?xml version="1.0" encoding="utf-8"?>
<objectAnimator
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:interpolator="@android:anim/accelerate_decelerate_interpolator"
        android:propertyName="translationY"
        android:valueType="floatType"
        android:valueFrom="1280"
        android:valueTo="0"
        android:duration="@android:integer/config_mediumAnimTime"/>

slide_down.xml

<?xml version="1.0" encoding="utf-8"?>
<objectAnimator
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:interpolator="@android:anim/accelerate_decelerate_interpolator"
        android:propertyName="translationY"
        android:valueType="floatType"
        android:valueFrom="0"
        android:valueTo="1280"
        android:duration="@android:integer/config_mediumAnimTime"/>

Multiple Animations

Finally, It's also possible to kick-off multiple fragment animations in a single transaction. This allows for a pretty cool effect where one fragment is sliding up and the other slides down at the same time:

getSupportFragmentManager()
        .beginTransaction()
        .setCustomAnimations( R.anim.abc_slide_in_top, R.anim.abc_slide_out_top ) // Top Fragment Animation
        .show( m_topFragment )
        .setCustomAnimations( R.anim.abc_slide_in_bottom, R.anim.abc_slide_out_bottom ) // Bottom Fragment Animation
        .show( m_bottomFragment )
        .commit()

Note:- You can check animation according to your requirement because above may be have issue.

Answer 6

I have same issue, i used simple solution

1)create sliding_out_right.xml in anim folder

  <?xml version="1.0" encoding="utf-8"?>
    <set xmlns:android="http://schemas.android.com/apk/res/android">
        <translate android:fromXDelta="0" android:toXDelta="-50%p"
            android:duration="@android:integer/config_mediumAnimTime"/>
        <alpha android:fromAlpha="1.0" android:toAlpha="0.0"
            android:duration="@android:integer/config_mediumAnimTime" />
    </set>

2) create sliding_in_left.xml in anim folder

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate android:fromXDelta="50%p" android:toXDelta="0"
        android:duration="@android:integer/config_mediumAnimTime"/>
    <alpha android:fromAlpha="0.0" android:toAlpha="1.0"
        android:duration="@android:integer/config_mediumAnimTime" />
</set>

3) simply using fragment transaction setCustomeAnimations() with two custom xml and two default xml for animation as follows :-

 fragmentTransaction.setCustomAnimations(R.anim.sliding_in_left, R.anim.sliding_out_right, android.R.anim.slide_in_left, android.R.anim.slide_out_right );

Answer 7

This is another solution which I use:

public class CustomAnimator {
    private static final String TAG = "com.example.CustomAnimator";

    private static Stack<AnimationEntry> animation_stack    = new Stack<>();

    public static final int                 DIRECTION_LEFT  = 1;
    public static final int                 DIRECTION_RIGHT = -1;
    public static final int                 DIRECTION_UP    = 2;
    public static final int                 DIRECTION_DOWN  = -2;

    static class AnimationEntry {
        View in;
        View    out;
        int     direction;
        long    duration;
    }

    public static boolean hasHistory() {
        return !animation_stack.empty();
    }

    public static void reversePrevious() {
        if (!animation_stack.empty()) {
            AnimationEntry entry = animation_stack.pop();
            slide(entry.out, entry.in, -entry.direction, entry.duration, false);
        }
    }

    public static void clearHistory() {
        animation_stack.clear();
    }

    public static void slide(final View in, View out, final int direction, long duration) {
        slide(in, out, direction, duration, true);
    }

    private static void slide(final View in, final View out, final int direction, final long duration, final boolean save) {

        ViewGroup in_parent = (ViewGroup) in.getParent();
        ViewGroup out_parent = (ViewGroup) out.getParent();

        if (!in_parent.equals(out_parent)) {
            return;
        }

        int parent_width = in_parent.getWidth();
        int parent_height = in_parent.getHeight();

        ObjectAnimator slide_out;
        ObjectAnimator slide_in;

        switch (direction) {
            case DIRECTION_LEFT:
            default:
                slide_in = ObjectAnimator.ofFloat(in, "translationX", parent_width, 0);
                slide_out = ObjectAnimator.ofFloat(out, "translationX", 0, -out.getWidth());
                break;
            case DIRECTION_RIGHT:
                slide_in = ObjectAnimator.ofFloat(in, "translationX", -out.getWidth(), 0);
                slide_out = ObjectAnimator.ofFloat(out, "translationX", 0, parent_width);
                break;
            case DIRECTION_UP:
                slide_in = ObjectAnimator.ofFloat(in, "translationY", parent_height, 0);
                slide_out = ObjectAnimator.ofFloat(out, "translationY", 0, -out.getHeight());
                break;
            case DIRECTION_DOWN:
                slide_in = ObjectAnimator.ofFloat(in, "translationY", -out.getHeight(), 0);
                slide_out = ObjectAnimator.ofFloat(out, "translationY", 0, parent_height);
                break;
        }

        AnimatorSet animations = new AnimatorSet();
        animations.setDuration(duration);
        animations.playTogether(slide_in, slide_out);
        animations.addListener(new Animator.AnimatorListener() {

            @Override
            public void onAnimationCancel(Animator arg0) {
            }

            @Override
            public void onAnimationEnd(Animator arg0) {
                out.setVisibility(View.INVISIBLE);
                if (save) {
                    AnimationEntry ae = new AnimationEntry();
                    ae.in = in;
                    ae.out = out;
                    ae.direction = direction;
                    ae.duration = duration;
                    animation_stack.push(ae);
                }
            }

            @Override
            public void onAnimationRepeat(Animator arg0) {
            }

            @Override
            public void onAnimationStart(Animator arg0) {
                in.setVisibility(View.VISIBLE);
            }
        });
        animations.start();
    }
}

The usage of class. Let's say you have two fragments (list and details fragments)as shown below

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/ui_container"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <FrameLayout
        android:id="@+id/list_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <FrameLayout
        android:id="@+id/details_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:visibility="gone" />
</FrameLayout>

Usage

View details_container = findViewById(R.id.details_container);
View list_container = findViewById(R.id.list_container);
// You can select the direction left/right/up/down and the duration
CustomAnimator.slide(list_container, details_container,CustomAnimator.DIRECTION_LEFT, 400);

You can use the function CustomAnimator.reversePrevious();to get the previous view when the user pressed back.
