To set background color for a transparent image, backgroundTint attribute can be used.

<android.support.v7.widget.AppCompatImageView
      android:layout_width="30dp"
      android:layout_height="30dp"
      android:background="@drawable/ic_star_white"
      android:backgroundTint="@color/colorPrimary" />

If you want to play with the opacity of your image, you are looking for the alpha parameter !

yourImageView.setAlpha(0.5) // alpha is between 0 and 1 (fully transparent/opaque)

If you want to change the color of your image, you'll have to work with ColorMatrixFilter :

ColorMatrix myColorMatrix = new ColorMatrix(new float[]{
    1,0,0,RGBValR, //red value
    0,1,0,RGBValG,
    0,0,1,RGBValB,
    0,0,0,1});
ColorMatrixColorFilter myFilter = new ColorMatrixColorFilter(myColorMatrix);
myImageView.setColorFilter(myfilter);
