在 android 中停止的 exoplayer 中恢复视频

如何解决在 android 中停止的 exoplayer 中恢复视频

每当点击一个项目时，我想在应用程序关闭时从停止的地方恢复视频。我尝试了以下但它没有做任何事情。当视频被点击时，它会从头打开，而不是从它离开的地方打开。这是实现

SimpleExoPlayer player;
long mLastPosition;
PlayerView playerView;
int position = 0;
ArrayList<Files> myFiles = new ArrayList<>();


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        position = getIntent().getIntExtra("position",0);
        String path = myFiles.get(position).getPath();
        Uri uri = Uri.parse(path);
        player= new SimpleExoPlayer.Builder(this).build();
        DataSource.Factory factory = new DefaultDataSourceFactory
                (this,Util.getUserAgent(this,"My App"));
        ExtractorsFactory extractorsFactory = new DefaultExtractorsFactory();

        MediaSource mediaSource = new ProgressiveMediaSource.Factory(factory,extractorsFactory).createMediaSource(uri);
        playerView.setPlayer(player);
        playerView.setKeepScreenOn(true);
        player.prepare(mediaSource);
        player.setPlayWhenReady(true);
   
    @Override
    protected void onPause() {
        super.onPause();
        player.setPlayWhenReady(false);
        player.getPlaybackState();
        if (player != null){
            player.stop();
            mLastPosition= player.getCurrentPosition();
        }
    }
  @Override
    protected void onResume() {
      super.onResume();
      if(mLastPosition!=0 && player!=null){
         player.seekTo(mLastPosition);
     }
 }

解决方法

您使用了错误的变量

@Override
    protected void onPause() {
        super.onPause();
        player.setPlayWhenReady(false);
        player.getPlaybackState();
        if (player != null){
            player.stop();
            last_position  = player.getCurrentPosition(); //what is last_position here?
           //it should be mLastPosition like this
           mLastPosition = player.getCurrentPosition();
        }
    }
  @Override
    protected void onResume() {
      super.onResume();
      if(mLastPosition!=0 && player!=null){
         player.seekTo(mLastPosition);
     }
 }
