所以我有 soundpool OnLoadCompleteListener ,它有这个代码 mStreamId = soundPool.play(sampleId, 1, 1, 1, 0, 1f); 我有 2 个按钮可以播放不同的声音池。我使用 mStreamId 来停止声音池。我的问题是,当我单击第一个按钮并播放声音并且单击第二个按钮时,它将停止第一个按钮的声音。这是我的代码:

    public class MainActivity extends Settings {
        SoundPool mSoundPool;
        int mSoundId;
        int mStreamId = 0;
    @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            this.setVolumeControlStream(AudioManager.STREAM_MUSIC);
    mSoundPool = new SoundPool(5, AudioManager.STREAM_MUSIC, 0);
            mSoundPool
                    .setOnLoadCompleteListener(new SoundPool.OnLoadCompleteListener() {
                        public void onLoadComplete(SoundPool soundPool,
                                int sampleId, int status) {
                            mStreamId = soundPool.play(sampleId, 1, 1, 1, 0, 1f);
}
                });

    }
//OnClick
public void button1(View view) {
        if (mStreamId != 0) {
            mSoundPool.stop(mStreamId);
        }

        String path = getFullFilePath(getApplicationContext(), et1.getText()
                .toString());
        mSoundId = mSoundPool.load(path, 1);
    }
public void button2(View view) {
        if (mStreamId != 0) {
            mSoundPool.stop(mStreamId);
        }

        String path = getFullFilePath(getApplicationContext(), et2.getText()
                .toString());
        mSoundId = mSoundPool.load(path, 1);
    }

因为你告诉它。如果您希望声音播放完成,请删除 stop 方法调用。Soundpool 将在播放声音时从池中返回下一个可用流。
