This is not a direct answer to this question. However, it may help someone.

Sometimes, we want to increase/decrease view's height because some of its child is is being added/removed (or just becoming visible/gone).

On those cases, you really can use Android default animation. As mentioned in other answers, you can set via:

Or in Java:

linearLayout.setLayoutTransition(new LayoutTransition());

If you created a custom view:

public StickerPickerView(final Context context, final AttributeSet attrs,
        final int defStyleAttr) {
    super(context, attrs, defStyleAttr);
    setLayoutTransition(new LayoutTransition());
}

For me, it was pretty satisfactory but I just tested on latest APIs. That will automatically add a fade in/out when your view becomes visible. It will also animate the height/width of your view when same changes (like when you change the visibility of one of the child views etc).

So, I recommend to at least give a try.
