java - Mediaplayer 播放几次后停止播放

Question

我有一个按钮，按下它会播放一个随机声音剪辑，然后播放另一个声音剪辑，然后通过一个媒体播放器播放另一个声音剪辑，但是多次按下该按钮(15-20 次)后，所有音频都会停止。我在播放最后一个音频剪辑后释放媒体播放器，所以我不认为这是原因。有什么指点吗？

public class Main extends Activity {


MediaPlayer mp;
Button generate;

@Override
protected void onCreate(Bundle savedInstanceState) {

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

    generate = (Button) findViewById(R.id.sound);

}

public void youSir (View view)
{
    generate.setVisibility(View.INVISIBLE);
    Random randomGenerator = new Random();
    int randomInt = randomGenerator.nextInt(3) + 1;
    switch (randomInt){
    case 1: mp = MediaPlayer.create(this, R.raw.beg); mp.start();
    break;
    case 2: mp = MediaPlayer.create(this, R.raw.begone); mp.start();
    break;
    case 3: mp = MediaPlayer.create(this, R.raw.begtwo); mp.start();
    break;
    }
    mp.setOnCompletionListener(new OnCompletionListener(){
        // @Override
        public void onCompletion(MediaPlayer arg0) {

            audioTwo();
         }
    });

}


protected void audioTwo() {
    // TODO Auto-generated method stub
    Random randomGenerator = new Random();
    int randomInt = randomGenerator.nextInt(3) + 1;
    switch (randomInt){
    case 1: mp = MediaPlayer.create(this, R.raw.start); mp.start();
    break;
    case 2: mp = MediaPlayer.create(this, R.raw.end); mp.start();
    break;
    case 3: mp = MediaPlayer.create(this, R.raw.mid); mp.start();
    break;
    }
    mp.setOnCompletionListener(new OnCompletionListener(){
        // @Override
        public void onCompletion(MediaPlayer arg0) {
            audioThree();
         }
    });
}

protected void audioThree() {
    // TODO Auto-generated method stub
    Random randomGenerator = new Random();
    int randomInt = randomGenerator.nextInt(3) + 1;
    switch (randomInt){
    case 1: mp = MediaPlayer.create(this, R.raw.three); mp.start();
    break;
    case 2: mp = MediaPlayer.create(this, R.raw.two); mp.start();
    break;
    case 3: mp = MediaPlayer.create(this, R.raw.one); mp.start();
    break;
    mp.setOnCompletionListener(new OnCompletionListener(){
        // @Override
        public void onCompletion(MediaPlayer arg0) {
            mp.stop();
            mp.release();
            generate.setVisibility(View.VISIBLE);
         }
    });
}

这是一个有点老的问题，但我尝试回答它，以防其他人遇到类似的问题。

您的音频资源即将耗尽。该代码实际上并没有释放所有 MediaPlayer 实例。每次运行仅释放三分之一。 audioTwo() 和 audioThree 将新的 MediaPlayer 实例分配给 mp 变量，但它们不会释放该实例已经存储在那里了。做类似的事情:

protected void audioTwo() {
    // RELEASING PREVIOUS MEDIAPLAYER
    mp.release();

    Random randomGenerator = new Random();
    int randomInt = randomGenerator.nextInt(3) + 1;
    switch (randomInt){
    case 1: mp = MediaPlayer.create(this, R.raw.start); mp.start();
    break;
    ...

audioThree() 也是如此。
