如何在更改为横向模式安卓时继续播放视频

您需要做的就是将其添加到AndroidManifest中的活动中.xml：

 android:configChanges="orientation"

您的视频活动应如下所示。

 <activity android:name=".VideoPlayerActivity" 
  android:configChanges="orientation" />

如果您的目标 API 级别 13 或更高版本，则除了值之外，还必须包括该值，如此处所述。您的视频活动应如下所示。screenSizeorientation

 <activity android:name=".VideoPlayerActivity" 
  android:configChanges="orientation|screenSize" />

然后将以下方法添加到VideoPlayerActivity：

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
}

全屏横向视频

AndroidManifext.xml （设置方向）

        <activity
        android:name=".Video1"
        android:screenOrientation="landscape" />

视频1.xml代码 ：

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout

<VideoView
    android:id="@+id/videoView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="center"
    app:layout_constraintLeft_toLeftOf="parent"
    app:layout_constraintRight_toRightOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    app:layout_constraintBottom_toBottomOf="parent">
</VideoView>

Video1.java 代码 ：

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_video1);

    videoView = findViewById(R.id.videoView);
    String fullScreen =  getIntent().getStringExtra("fullScreenInd");
    if("y".equals(fullScreen)){
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
        getSupportActionBar().hide();
    }

    Uri videoUri = Uri.parse("android.resource://"+getPackageName()+"/"+R.raw.YOUR_VIDEO_NAME);

    videoView.setVideoURI(videoUri);

    mediaController = new FullScreenMediaController(this);
    mediaController.setAnchorView(videoView);

    videoView.setMediaController(mediaController);
    videoView.start();
    }
}
