Android 以横向和全屏方式播放视频

在具有

视频视图的应用程序上工作

。但是视频是纵向的，不是全屏的。我想在横向和全屏播放。这是我的xml代码

    <VideoView
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:id="@+id/FBG"
    android:layout_alignParentTop="true"
    android:layout_alignParentEnd="true"
    android:layout_alignParentStart="true"/>

---

要使其成为横向的，如果需要动态更改方向，可以通过编程方式进行：

    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

或静态，方法是将其添加到Manifest.xml文件中：

    <activity
        android:name="...."
        android:screenOrientation="landscape"
        />

或者使用沉浸式全屏模式，如下所述：

这比我在这里所写的要好得多。
