There are android scale types which you can refer CENTER, CENTER_CROP, CENTER_INSIDE, FIT_CENTER, FIT_END, FIT_START, FIT_XY and MATRIX. which can be used as per your requirement. But as you mentioned you can try android:scaleType="center_crop" which crops the image a bit but covers the whole screen
