android - SoundPool streamid

Question

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 soundpools。我使用 mStreamId 来停止 soundpool。我的问题是当我单击第一个按钮时它播放声音并且我单击第二个按钮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);
    }

Answer 1

soundId 和 streamId 分开保存。

onLoadComplete 在加载后调用，所以当您按下 button2 时，streamId 是 button1 播放的声音的 id。
