Android pop fragment from backstack with animation

Question

I have an activity that loads a Fragment A in it. Fragment A contains ListView and when clicking on list item I load another Fragment B in place of Fragment A to show the listvi

Answer 1

If you want backstack animations you'll need to use:

setCustomAnimations(int enter, int exit, int popEnter, int popExit)

Something like:

setCustomAnimations(R.anim.enter_from_left, R.anim.enter_from_left,
        R.anim.exit_to_left, R.anim.exit_to_left); 

Answer 2

With navigation component is very easy too:

        app:enterAnim="@anim/slide_in_left"
        app:exitAnim="@anim/slide_out_right"
        app:popEnterAnim="@anim/slide_in_right"
        app:popExitAnim="@anim/slide_out_left"

Answer 3

In my case

FragmentTransaction ft = getFragmentManager().beginTransaction();
        ft.setCustomAnimations(android.R.anim.slide_in_left, 
                               android.R.anim.slide_out_right, 
                               R.anim.slide_in_right,
                               R.anim.slide_out_left);
        ft.replace(R.id.fragment_container, targetFragment).addToBackStack(null).commit();

this line

ft.setCustomAnimations(android.R.anim.slide_in_left, android.R.anim.slide_out_right, 
                       R.anim.slide_in_right, R.anim.slide_out_left);

would create perfect animation.

slide_in_right

<?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>

slide_out_left

<?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>
