针对slide_in xml:

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>

对于slide_out xml:

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代码:

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

将两个xml文件都放入res/anim文件夹中.

put both xml files in res/anim folder.
