Answer 1

add scaleType to ImageView

<ImageView
   android:id="@+id/flag"
   android:layout_width="fill_parent"
   android:layout_height="fill_parent"
   android:layout_alignParentLeft="true"
   android:layout_alignParentRight="true"
   android:src="@drawable/ic_launcher" 
   android:scaleType="fitXY"/>

Answer 2

SET android:adjustViewBounds="true" attribute in xml or imageView.setAdjustViewBounds(true) in Java.

ALSO

You can use android:scaleType="fitXY" in XML:

<ImageView
    android:id="@+id/flag"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_alignParentLeft="true"
    android:layout_alignParentRight="true"
    android:scaleType="fitXY"
    android:src="@drawable/ic_launcher" />

There are Many option for android:scaleType

Answer 3

Android have provided us many attributes to work with ImageView.

You can use adjustViewBounds and scaleType property in your case. Check example below:

<ImageView
    android:id="@+id/flag"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_alignParentLeft="true"
    android:layout_alignParentRight="true"
    android:scaleType="fitXY"
    android:adjustViewBounds="true"
    android:src="@drawable/ic_launcher" />
