How to change ImageView Source - Android?

Consider you have set the source for the ImageView in your xml as below,

<ImageView  

            android:layout_width="wrap_content" 

            android:layout_height="wrap_content"

            android:id="@+id/myImgView"

            android:src="@drawable/something"/>

To change the image source programatically,

myImgView.setImageResource(R.drawable.ball);

or,

myImgView.setImageDrawable(getResources().getDrawable(R.drawable.ball));
