Making a smooth fade out for imageview in android

Question

I managed to make the imageView dissapear after 10 seconds(a tutorial image on my mainActivity). But i want to make a smooth fade out because like this it doesn`t look good,

Answer 1

take hint from this code snippet. The code required goes like this-

Animation fadeOut = new AlphaAnimation(1, 0);  // the 1, 0 here notifies that we want the opacity to go from opaque (1) to transparent (0)
fadeOut.setInterpolator(new AccelerateInterpolator());
fadeOut.setStartOffset(500); // Start fading out after 500 milli seconds
fadeOut.setDuration(1000); // Fadeout duration should be 1000 milli seconds

Now set this to an element say an image view -

myImageView.setAnimation(fadeOut);

Answer 2

Replace img.setVisibility(View.GONE) in your code with a call to fadeOutAndHideImage(img) which is defined like this:

  private void fadeOutAndHideImage(final ImageView img)
  {
    Animation fadeOut = new AlphaAnimation(1, 0);
    fadeOut.setInterpolator(new AccelerateInterpolator());
    fadeOut.setDuration(1000);

    fadeOut.setAnimationListener(new AnimationListener()
    {
            public void onAnimationEnd(Animation animation) 
            {
                  img.setVisibility(View.GONE);
            }
            public void onAnimationRepeat(Animation animation) {}
            public void onAnimationStart(Animation animation) {}
    });

    img.startAnimation(fadeOut);
}

It will apply the fade out animation first, then will hide the image view.
