Android Activity transition slide in/out animation

This is a very common effect, however the Android framework only provides the slide in animation. This is how I implement all the sliding transition animation. There’s in total 4 XMLs to define the animation, and with the use of overridePendingTransition() in appropriate location you can implement this easily.

pull_in_left.xml

<?xml version=“1.0” encoding=“utf-8”?>

<translate xmlns:android=“http://schemas.android.com/apk/res/android”

android:duration=“300”

android:fromXDelta=“-100%”

android:toXDelta=“0%”

android:interpolator=“@android:anim/decelerate_interpolator”

pull_in_right.xml

<?xml version=“1.0” encoding=“utf-8”?>

<translate xmlns:android=“http://schemas.android.com/apk/res/android”

android:duration=“300”

android:fromXDelta=“100%”

android:toXDelta=“0%”

android:interpolator=“@android:anim/decelerate_interpolator”

push_out_left.xml

<?xml version=“1.0” encoding=“utf-8”?>

<translate xmlns:android=“http://schemas.android.com/apk/res/android”

android:duration=“300”

android:fromXDelta=“0%”

android:interpolator=“@android:anim/decelerate_interpolator”

android:toXDelta=“-100%” />

push_out_right.xml

<?xml version=“1.0” encoding=“utf-8”?>

<translate xmlns:android=“http://schemas.android.com/apk/res/android”

android:duration=“300”

android:fromXDelta=“0%”

android:interpolator=“@android:anim/decelerate_interpolator”

android:toXDelta=“100%” />

Usage

When starting new Activity

add overridePendingTransition right after you call startActivity

Intent intent = new Intent(mContext, NextActivity.class);

startActivity(intent);

overridePendingTransition(R.anim.pull_in_left, R.anim.push_out_right);

When Back to previous Activity

When the user click back button, you will have to play the reserve animation to go back to previous Activity, you can do so by overriding the
onBackPressed method

@Override

public void onBackPressed() {

super.onBackPressed();

overridePendingTransition(R.anim.pull_in_right, R.anim.push_out_left);
