Create XML files slide_down.xml and slide_down2.xml under the folder /res/anim/, show two approachs to define translate on X and Y.
slide_down.xml, One <Set> have two <translate>, for X and Y separately.
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<translate
android:fromYDelta="0"
android:toYDelta="100%p" />
<translate
android:fromXDelta="0"
android:toXDelta="100%p" />
</set>
slide_down2.xml, One <Set> have one <translate>, have X and Y together.
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<translate
android:fromXDelta="0"
android:fromYDelta="0"
android:toXDelta="100%p"
android:toYDelta="100%p" />
</set>
