U can try adding it in code

ImageView backgroundImg = (ImageView) findViewById(R.id.backgroundImg);
backgroundImg.setBackgroundColor(Color.rgb(100, 100, 50));

This will also solve your problem. Just add this in your ImageView tag.

android:background="@android:color/red"

Check this Im not sure. But check this snippet

You can simply use ArgbEvaluator which is available since API 11 (Honeycomb):

ValueAnimator anim = new ValueAnimator();
anim.setIntValues(color1, color2);
//anim..setIntValues(Color.parseColor("#FFFFFF"), Color.parseColor("#000000"));
anim.setEvaluator(new ArgbEvaluator());
anim.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
    @Override
    public void onAnimationUpdate(ValueAnimator valueAnimator) {
        backgroundImg.setBackgroundColor((Integer)valueAnimator.getAnimatedValue());
    }
});

anim.setDuration(300);
anim.start();

Even better, beginning with API 21 (Lollipop 5.0) you can replace the first 3 lines in the code above with one:

ValueAnimator anim = ValueAnimator.ofArgb(color1, color2)
