android - 在媒体播放器中重复播放音频

Question

对于媒体播放器中的重复音频，编写此代码但无法正常工作:

seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
      @Override
      public void onProgressChanged(SeekBar seekBar, int i, boolean b) {
        if (b) {
          G.mediaPlayer.seekTo(i);
        }
        if (i >= G.mediaPlayer.getDuration()) {
          if (isRepeat) {
            G.mediaPlayer.seekTo(0);
            G.mediaPlayer.start();
          }else {
            G.mediaPlayer.seekTo(0);
            G.mediaPlayer.pause();
          }
        }
      }

要播放音频，请执行以下操作:

    public void playSongWithIndex(final int songIndex) {
    progressBar.setVisibility(View.VISIBLE);
    if (music_exist.exists()) {
      playMusicOfflineMode();
    } else {
      try {
        G.mediaPlayer.reset();
        G.mediaPlayer.setDataSource(songList.get(songIndex).getFile_128());
        G.mediaPlayer.prepareAsync();
        G.mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
          @Override
          public void onPrepared(MediaPlayer mediaPlayer) {
            runOnUiThread(new Runnable() {
              @Override
              public void run() {

              }
            });

            G.mediaPlayer.start();
            seekBar.setMax(G.mediaPlayer.getDuration());
            progressBar.setVisibility(View.INVISIBLE);

            timer = new Timer();
            timer.schedule(new MainTimer(), 0, 1000);

          }
        });
      } catch (IllegalArgumentException | IllegalStateException | IOException e) {
        e.printStackTrace();
      }
    }
  }

但重复音频有时会起作用，有时当搜索栏结束时停止并且不起作用。请帮我如何重复音频？

您可以将媒体播放器循环设置为 true，使用此代码:

 G.mediaPlayer.setLooping(true);

如果你想知道玩家什么时候结束，你应该像这样使用 OnCompletionListener:

 G.mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
        @Override
        public void onCompletion(MediaPlayer mediaPlayer) {


        }
    });
