You can try to scale the image to X,Y coordinates by setting:

android:scaleType="fitXY"

property.

By default, Android maintain multiple folders for the images with different resolutions. Reason behind that is the resolution of the Android Device on which the application is gonna run.

hdpi - maintain images for the Android Broad Screen set or Android Phones with the Higher resolution.
ldpi - for Lower images quality.
mdpi - for medium images support.
xhdi - images folder for devices with maximum resolution.

Android OS will select the image itself by checking the compatible device and its resolution. Hope this helps your cause.
