With the new animation API that was introduced in Android 3.0 (Honeycomb) it is very simple to create such animations.
Sliding a View
down by a distance:
view.animate().translationY(distance);
You can later slide the View
back to its original position like this:
view.animate().translationY(0);
You can also easily combine multiple animations. The following animation will slide a View
down by its height and fade it in at the same time:
// Prepare the View for the animation
view.setVisibility(View.VISIBLE);
view.setAlpha(0.0f);
// Start the animation
view.animate()
.translationY(view.getHeight())
.alpha(1.0f)
.setListener(null);
You can then fade the View
back out and slide it back to its original position. We also set an AnimatorListener
so we can set the visibility of the View
back to GONE
once the animation is finished:
view.animate()
.translationY(0)
.alpha(0.0f)
.setListener(new AnimatorListenerAdapter() {
@Override
public void onAnimationEnd(Animator animation) {
super.onAnimationEnd(animation);
view.setVisibility(View.GONE);
}
});
