TabHost Tab Animation

Question

Hey. When the user clicks on another tab, should the animation appear in the next view? What is the best thing for?

Answer 1

By default, animation is not applied, at least on honeycombs. The view will simply appear.

You can do something like this if you want to revive it:

Find the child on the tab and play the animation on it.

Example: First install the listener:

exampleTabhost.setOnTabChangedListener(new OnTabChangeListener()
    {
        @Override
            public void onTabChanged(String tabId)
            {
                refreshTabHostUI(exampleTabhost);
            }
        });

In your listener, play the animation on the tab:

View tab1 = th.findViewById(R.id.tab1);
    if( tab1 != null )
        playAnim(tab1, getBaseContext(), android.R.anim.fade_in, 500);

Animation Playback Function:

public Animation playAnim( View v, Context con, int animationid, int startOffset )
    {
        if( v != null )
        {
            Animation animation = AnimationUtils.loadAnimation(con, animationid  );
            animation.setStartOffset(startOffset);
            v.startAnimation(animation);

            return animation;
        }
        return null;
    }
