I wrote an application, which has the same effect. What I did is, I created a FrameLayout which has the ImageView and another View which has the same height of the ImageView. Then I add a transparent gradient background to the View.

布局文件:
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:layout_width="match_parent"
android:layout_height="180dp"
android:src="@drawable/image"
android:adjustViewBounds="true" />
<View
android:layout_width="match_parent"

</FrameLayout>
