Mediaplayer播放几次后停止播放

Question

我有一个按钮，按下它播放一个随机的声音剪辑，然后是另一个，然后通过一个媒体播放器，然而，在按下按钮多次(15-20次)后，所有的音频都会停止。我会在播放完最后一个音频片段后释放mediaplayer，所以我看不出这是原因。有什么建议吗？

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，但我试图回答它，以防其他人有类似的问题。

您的音频资源即将耗尽。代码实际上并不会释放所有MediaPlayer实例。它每次运行只释放三个中的一个。audioTwo()和audioThree将新的MediaPlayer实例赋给mp变量，但是它们不会释放已经存储在其中的实例。做一些类似的事情：

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。
