slide up xml animation on change activity in android

How to apply slide animation between two activities in Android?

I need to know how to make activity slideup xml animation. like what they have done for fadein and fadeout.

for slide_in xml :

<translate 
      xmlns:android="http://schemas.android.com/apk/res/android"
      android:duration="250" 
      android:fromXDelta="-100%p" 
      android:toXDelta="0%p">
</translate>

for slide_out xml:

<translate
      xmlns:android="http://schemas.android.com/apk/res/android" 
      android:duration="200" 
      android:fromXDelta="0" 
      android:toXDelta="100%p">
</translate>

Java code :

Intent intent = new Intent(this, newActivity.class);
startActivity(intent);
overridePendingTransition(R.anim.slide_in, R.anim.slide_out);

put both xml files in res/anim folder.
