Android: Using linear gradient as background looks banded

by

As Romain Guy suggests:

listView.getBackground().setDither(true);

solves my problem

If this is not enough especially for AMOLED and/or hdpi devices try this:

@Override
public void onAttachedToWindow() {
    super.onAttachedToWindow();
    Window window = getWindow();
    window.setFormat(PixelFormat.RGBA_8888);
}
