If you want to fit the ImageView width then You have to ignore height. And by default will not strech for you to keep aspect ratio, so you need to add another attributes for adjust view bounds. So lastly you will have your code chages as follows for an ImageView: 

 android:layout_width="match_parent"
 android:adjustViewBounds="true"

The adjust View bounds will adjust to a particular height while keeping the aspect ratio.

Also to avoid future mistakes again in your code you have nested two RelativeLayout's which I guess is due backgrounds. If there is no need for that If do not care about space. The inner RelativeLayout View height and width should be set to match_parent!. Happy Coding!

Change layout_width of ImageView to match_parent and add one new attribute to it: android:adjustViewBounds="true".

Your ImageView's layout_width and layout_height are set to wrap_content instead of match_parent.
