当我按下 android 主页按钮时，通过本机模块播放 pip 视频并传递视频 url 和视频的当前持续时间，并且本机模块接受该参数和意图给 Video Activity。在 Video Activity OnCreate 方法中，我尝试显示 PiP 视频。当我按下在反应本机图标上，画中画模式显示，但我无法返回反应本机视图。当我按下 Android 主页按钮时，画中画模式无法显示。

PiPModule.java

public class PiPModule extends ReactContextBaseJavaModule {

public PiPModule(ReactApplicationContext reactContext){
    super(reactContext);
}

@NonNull
@Override
public String getName() {
    return "PiPModule";
}

@ReactMethod
public void showPiPVideo(String videoURL,int seekToDuration)
{
    Toast.makeText(getReactApplicationContext(),"showPiPVideo is working",Toast.LENGTH_SHORT).show();
    Intent intent = new Intent(getCurrentActivity(), PiPVideoActivity.class);
    intent.putExtra("VIDEO_URL",videoURL);
    intent.putExtra("VIDEO_CURRENT_DURATION",seekToDuration);
    getCurrentActivity().startActivity(intent);
}

}

在 React-Native 组件中的使用

import {NativeModules} from 'react-native'
const pipVideo = NativeModules.PiPModule;
pipVideo.showPiPVideo(videoURL, Math.floor(currentTime) * 1000);

画中画活动

public class PiPVideoActivity extends AppCompatActivity {

private String videoPath;
private int videoDuration;
VideoView myVideoView;

@RequiresApi(api = Build.VERSION_CODES.O)
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_pip_video);

    Intent i = getIntent();

    if(i != null){
        myVideoView = (VideoView) findViewById(R.id.videoView);
        videoPath = i.getStringExtra("VIDEO_URL");
        videoDuration = i.getIntExtra("VIDEO_CURRENT_DURATION",0);
        PlayVideo();
    }
    else{
        Toast.makeText(PiPVideoActivity.this, "VideoURL not found", Toast.LENGTH_SHORT).show();
    }

    PictureInPictureParams params = new PictureInPictureParams
            .Builder()
            .setAspectRatio(new Rational(1,1))
            .build();
    enterPictureInPictureMode(params);

}

private void PlayVideo() {
    try {
        getWindow().setFormat(PixelFormat.TRANSLUCENT);
        Uri video = Uri.parse(videoPath);
        myVideoView.setVideoURI(video);
        myVideoView.requestFocus();
        myVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
            public void onPrepared(MediaPlayer mp) {
                //seek to receive miliseconds
                myVideoView.seekTo(videoDuration);
                myVideoView.start();
            }
        });

    } catch (Exception e) {
        System.out.println("Video Play Error :" + e.toString());
        finish();
    }

}

}
