我有一個soundpool,將加載SD卡中的文件,我用mstreamID來停止它,我在OnLoadCompleteListener中使用mstreamID,因此可以加載文件。我使用2個按鈕來播放soundpool不同的聲音。但是,當我點擊第一個按鈕,並播放1聲音時,我點擊第二個按鈕,它會停止第一個按鈕的聲音。Soundpool不同streamid
這裏是我的代碼:
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);
}
// et1 is extended from Settings.java
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);
}
