android - 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?

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();
