如何在另一个音频文件开始播放时暂停音频文件，反之亦然

Question

我有两个音频文件。我希望如果一个音频正在播放并且用户单击第二个音频，则第一个音频将暂停（同时保持进度并在再次播放时继续播放）并开始第二个音频，反之亦然。

如何实现此功能？

我是 Android 媒体的新手

代码

onClick在最后，如果你想直接跳转到XML，onClick在最后实现，如果你想查看XML请告诉我，我会更新它。

public class MainActivity extends AppCompatActivity {
    MediaPlayer player1, player2;
    SeekBar seekBar1, seekBar2;
    TextView currentTime1, currentTime2;
    TextView remainingTime1, remainingTime2;
    ImageView play1, play2;
    int totalTime1, totalTime2;

    @Override

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // PlayButton    *  The onClick is in the last if you want to jump directly there  *

        play1 = findViewById(R.id.playbtn);
        play2 = findViewById(R.id.playbtn2);

        // TimeLables

        currentTime1 = findViewById(R.id.currentTime1);
        currentTime2 = findViewById(R.id.currentTime2);
        remainingTime1 = findViewById(R.id.totalTime1);
        remainingTime2 = findViewById(R.id.totalTime2);

        // MediaPlayer

        player1 = MediaPlayer.create(this, R.raw.dog_howl);
        player2 = MediaPlayer.create(this, R.raw.dog_bark);
        player1.setLooping(false);
        player1.seekTo(0);
        totalTime1 = player1.getDuration();
        player2.setLooping(false);
        player2.seekTo(0);
        totalTime2 = player2.getDuration();


        //SeekBar *Progress*

Answer 1

添加此代码：-

public void playBtnClick1(View view) {

    if (player2.isPlaying()) {
        player2.pause();
        play2.setImageResource(R.drawable.ic_baseline_play_circle_filled_24);
    }
    
    if (!player1.isPlaying()) {
        // Stoping
        player1.start();
        play1.setImageResource(R.drawable.ic_baseline_pause_circle_filled_24);
    } else {
        // Playing
        player1.pause();
        play1.setImageResource(R.drawable.ic_baseline_play_circle_filled_24);
    }

}

public void playBtnClick2(View view) {

    if (player1.isPlaying()) {
        player1.pause();
        play1.setImageResource(R.drawable.ic_baseline_play_circle_filled_24);
    }
    
    if (!player2.isPlaying()) {
        // Stoping
        player2.start();
        play2.setImageResource(R.drawable.ic_baseline_pause_circle_filled_24);
    } else {
        // Playing
        player2.pause();
        play2.setImageResource(R.drawable.ic_baseline_play_circle_filled_24);
    }

}

Answer 2

如果我明白您的意思，您的解决方案真的很简单。当你想玩新的时候你可以停止上一个。

只需使用这两种方法：

    player1.start();
    player2.stop();

播放器 2 开始停止播放器 1。
