回答1:

i think your images are stretching use the properties for imageview to get full image ..

 android:scaleType="matrix"

Controls how the image should be resized or moved to match the size of this ImageView.

Have you compress or changed the format of image? while doing so sometimes images gets distorted. And make sure that, what you want to set in ImageView android:background or android:src ?
