How to change the default transition between activities?

In android the default transition between activities is to slide from left to right.But with custom animations we can change that.First create a folder inside the res/drawable folder called “anim”.Then create a file named “fade.xml” and copy this code into it.

<?xml version="1.0" encoding="utf-8"?>

<alpha xmlns:android="http://schemas.android.com/apk/res/android"

android:interpolator="@android:anim/accelerate_interpolator"

android:fromAlpha="0.0" android:toAlpha="1.0"

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

create another file named “hold.xml” in the same place hold.xml.

<?xml version="1.0" encoding="utf-8"?>

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

android:interpolator="@android:anim/accelerate_interpolator"

android:fromXDelta="0" android:toXDelta="0"  android:duration="@andro id:integer/config_longAnimTime" /> and just before starting the activity write down the following code startActivity(new Intent(ActivityAnimation.this, SecondClass.class)); overridePendingTransition(R.anim.fade.xml,R.anim.hold.xml);
