You have to set animation to the layout

You can provide fade_in or fad_out animation to the layout

to set fade_in to layout use the following code

Animation mAnim = AnimationUtils.loadAnimation(this, android.R.anim.fade_in);
layout.startAnimation(mAnim);

to set fade_out to layout use the following code

Animation mAnim = AnimationUtils.loadAnimation(this, android.R.anim.fade_out);
        layout.startAnimation(mAnim);
