android – Fragment transaction animation: slide in and slide out

Posted by: admin March 11, 2020 Leave a comment

Questions:

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 that the animation it’s inverted: old fragment slide out to the left, and new fragment slide in to the right, but no value of R.animfile seems to be useful for my scope.

How can I do it?

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();

Answer:

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:

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:

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:

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.
