/**

 * Displays image resources, for example {@link android.graphics.Bitmap}

 * or {@link android.graphics.drawable.Drawable} resources.

 * ImageView is also commonly used to {@link #setImageTintMode(PorterDuff.Mode)

 * apply tints to an image} and handle {@link #setScaleType(ScaleType) image scaling}.

 * ImageView is also commonly used to

 * <a href="#setImageTintMode(android.graphics.PorterDuff.Mode)">apply tints to an image</a> and

 * handle <a href="#setScaleType(android.widget.ImageView.ScaleType)">image scaling</a>.

 *

 * <p>

 * The following XML snippet is a common example of using an ImageView to display an image resource:

 *     <ImageView

 *         android:layout_width="wrap_content"

 *         android:layout_height="wrap_content"

 *         android:src="@mipmap/ic_launcher"

 *         android:src="@drawable/my_image"

 *         android:contentDescription="@string/my_image_description"

 *         />

 * </LinearLayout>
