Answer 1

Write the Following ImageView Tag in your Parent Layout.

<ImageView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:scaleType="fitXY"
    android:background="@drawable/blacksquare"
    />

and you can also remove the Paddings from your parent Layout Tag to get fit the Image View in screen without padding..
