I am making a picture gallery app. I current have a imageview with a text view at the bottom. Currently it is just semitransparent. I want to make it fade in, wait 3 second,
protected AlphaAnimation fadeIn = new AlphaAnimation(0.0f , 1.0f ) ;
protected AlphaAnimation fadeOut = new AlphaAnimation( 1.0f , 0.0f ) ;
txtView.startAnimation(fadeIn);
txtView.startAnimation(fadeOut);
fadeIn.setDuration(1200);
fadeIn.setFillAfter(true);
fadeOut.setDuration(1200);
fadeOut.setFillAfter(true);
fadeOut.setStartOffset(4200+fadeIn.getStartOffset());
Works perfectly for white backgrounds. Otherwise, you need to switch values when you instantiate AlphaAnimation class. Like this:
AlphaAnimation fadeIn = new AlphaAnimation( 1.0f , 0.0f );
AlphaAnimation fadeOut = new AlphaAnimation(0.0f , 1.0f );
This works with black background and white text color.
