java - Android，Soundpool 类 - 循环播放声音时出现自动暂停问题

Question

我在使用 soundpool 类的程序中遇到问题。我启动了 soundpool builder 并毫无问题地加载了我的声音。我希望能够使用多个切换按钮来打开和关闭特定的声音。我可以打开和关闭切换按钮，但是例如，如果我打开两个或多个切换按钮，然后暂停一个……其余的将停止。我不想这样，我希望其他声音继续播放。这是我的代码。另外，如果有人可以帮我清理一下，那会很有帮助。提前致谢。

 protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        bT1 = (ToggleButton) findViewById(R.id.firstToggle);
        bT2 = (ToggleButton) findViewById(R.id.secondToggle);
        bT1.setOnClickListener(this);
        bT2.setOnClickListener(this);
        bT3 = (ToggleButton) findViewById(R.id.thirdToggle);
        bT4 = (ToggleButton) findViewById(R.id.fourthToggle);
        bT3.setOnClickListener(this);
        bT4.setOnClickListener(this);
        bT5 = (ToggleButton) findViewById(R.id.fifthToggle);
        bT6 = (ToggleButton) findViewById(R.id.sixToggle);
        bT5.setOnClickListener(this);
        bT6.setOnClickListener(this);
        bT7 = (ToggleButton) findViewById(R.id.seventhToggle);
        bT8 = (ToggleButton) findViewById(R.id.eighthToggle);
        bT7.setOnClickListener(this);
        bT8.setOnClickListener(this);

将此添加到您的 OnPause 方法:

@Override
public void onPause() {
   super.onPause();   

   ourSounds.release();
   ourSounds = null;
}

更新:

请尝试使用 ourSounds.autoPause(); 而不是 ourSounds.autoPause(); 例如:

case R.id.firstToggle:
            if(bT1.isChecked()) {
                ourSounds.play(soundFx, 1, 1, 1, -1, 1);
            }
            else {
                ourSounds.pause(soundFx);
            }
            break;
