直接上代碼：
布局文件就是兩個全屏的videoview和imageview重疊
<LinearLayout?xmlns:android="/apk/res/android"android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="@+id/pictureView"
android:scaleType="fitXY"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
<VideoView
android:id="@+id/videoView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
</LinearLayout>
