Android完全旋转-90度

Question

在处理数字标牌项目时，我们必须提供显示纵向图像和视频的功能。虽然图像效果很好，但视频会让我们的 Minix Neo x9 播放器做出奇怪的事情。

播放器不仅可以改变视频视图或应用程序的旋转，而且在以纵向模式播放视频后整个Android系统都会旋转。

的AndroidManifest.xml

 <activity
        android:name="com.example"
        android:label="@string/app_name"
        android:theme="@style/FullscreenTheme"
        android:launchMode="singleTask"
        android:stateNotNeeded="true"
        android:screenOrientation="portrait"
        >

fragment_video.xml

<FrameLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/video_frame"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/black"
android:alpha="0">

<VideoView
    android:id="@+id/video"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="center"/>

</FrameLayout>

之前有没有人遇到过这类问题？

从硬件提供商处获得反馈。说这是默认固件中的一个错误。
