Answer 1

res/anim/

activity_fade_in.xml :

<?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="500" />

activity_fade_out.xml:

<?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="1.0" android:toAlpha="0.0"
   android:fillAfter="true"
   android:duration="500" />

In Activity or Fragment:

 startActivity(intent);
 overridePendingTransition(R.anim.activity_fade_in,R.anim.activity_fade_out);
