        android:layout_height="wrap_content"
        android:flipInterval="2000"
                android:layout_marginBottom="20dip" >

                        android:textSize="26sp"
                        android:text="@string/animation_2_text_1"/>

                        android:text="@string/animation_2_text_2"/>
                <TextView
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        android:gravity="center_horizontal"
                        android:textSize="26sp"
                        android:text="@string/animation_2_text_3"/>
                <TextView

                        android:layout_height="wrap_content"
                        android:gravity="center_horizontal"
                        android:textSize="26sp"
                        android:text="@string/animation_2_text_4"/>
    </ViewFlipper>

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="5dip"
        android:text="@string/animation_2_instructions"
    />

    <Spinner android:id="@+id/spinner"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
    />

</LinearLayout>

<set xmlns:android="http://schemas.android.com/apk/res/android">
	<translate android:fromYDelta="100%p" android:toYDelta="0" android:duration="300"/>
	<alpha android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="300" />
</set>

<set xmlns:android="http://schemas.android.com/apk/res/android">
	<translate android:fromYDelta="0" android:toYDelta="-100%p" android:duration="300"/>
	<alpha android:fromAlpha="1.0" android:toAlpha="0.0" android:duration="300" />

2.有右到左进入消失

push_left_in.xml

<set xmlns:android="http://schemas.android.com/apk/res/android">
	<translate android:fromXDelta="100%p" android:toXDelta="0" android:duration="300"/>
	<alpha android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="300" />
</set>

<set xmlns:android="http://schemas.android.com/apk/res/android">
	<translate android:fromXDelta="0" android:toXDelta="-100%p" android:duration="300"/>
	<alpha android:fromAlpha="1.0" android:toAlpha="0.0" android:duration="300" />
</set>

这是有android自带的

4.在三维上进行动画

hyperspace_in.xml

<alpha xmlns:android="http://schemas.android.com/apk/res/android" android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="300" android:startOffset="1200" />

hyperspace_out.xml

<set xmlns:android="http://schemas.android.com/apk/res/android" android:shareInterpolator="false">

	<scale 
		android:interpolator="@android:anim/accelerate_decelerate_interpolator"
		android:fromXScale="1.0" 
		android:toXScale="1.4" 
		android:fromYScale="1.0" 
		android:toYScale="0.6" 
		android:pivotX="50%"
		android:pivotY="50%"
		android:fillAfter="false"
		android:duration="700" />


	<set 
		android:interpolator="@android:anim/accelerate_interpolator"
                android:startOffset="700">
		
		<scale
			android:fromXScale="1.4" 
			android:toXScale="0.0"
		        android:fromYScale="0.6"
	 		android:toYScale="0.0" 
	 		android:pivotX="50%" 
	 		android:pivotY="50%" 
	 		android:duration="400" />
 		
		<rotate 
			android:fromDegrees="0" 
			android:toDegrees="-45"
	 		android:toYScale="0.0" 
	 		android:pivotX="50%" 
	 		android:pivotY="50%"
	 		android:duration="400" />
	</set>

</set>
