How can I make an image transparent on Android?

Question

I am using a linear layout and frame layout. In the linear layout I keep an image as background and in the frame layout I keep an imageView. In that imageView I give an image.

Answer 1

Set transparency using setAlpha(float alpha). The below code works for me were I used an alpha value in float, 0 - 1.

• 0: Full Transparent
• 0.5 - 50%: Transparent

• 1: Full Opaque

  ImageView imageView = (ImageView) itemView.findViewById(R.id.imageView); imageView.setImageResource(mResources[position]); imageView.setAlpha(.80f);
