How to highlight ImageView when focused or clicked?

You need to assign the src attribute of the ImageView a state list drawable.

Adding text to ImageView in Android

To add a text to your ImageView you can do this: <RelativeLayout> // Only works inside a RelativeLayout <ImageView android:id=”@+id/myImageView” android:layout_width=”wrap_content” android:layout_height=”wrap_content” android:src=”https://stackoverflow.com/questions/3404582/@drawable/myImageSouce” /> <TextView android:id=”@+id/myImageViewText” android:layout_width=”wrap_content” android:layout_height=”wrap_content” android:layout_alignLeft=”@+id/myImageView” android:layout_alignTop=”@+id/myImageView” android:layout_alignRight=”@+id/myImageView” android:layout_alignBottom=”@+id/myImageView” android:layout_margin=”1dp” android:gravity=”center” android:text=”Hello” android:textColor=”#000000″ /> </RelativeLayout>
