Android Rotation Animation

Android Animation List is here.And here i worked with Rotate3dAnimation.

 Android Rotate3dAnimation  rotates the view on the Y axis between two specified angles. This animation also adds a translation on the Z axis (depth) to improve the effect.here i rotate view to 0 to 90 degrees.then view is hide and next view is display.The secondview is visible after complete of rotation of firstview.and  secondview is load using -90 to 0.then when i go back  secondview is rotate again 0 to 90 and it disappear.and firstview is load using rotate it to 90 to 0.

So,using Y axis we can rotate view.And after rotation we can hide and show view.

We have to rotate mainview,that accomplish 3d rotation.and firstview and secondview is child of mainview.those hide and show meanwhile 3dRotation.
