我有两个按钮，如果按下它们就会发出声音。我想同时按下这两个键来同时听到这两种声音。至今：

@Override // 处理导航箭头的触摸 public boolean onTouch(View v, MotionEvent event) {

    int action = event.getActionMasked();

    switch (action){

    case MotionEvent.ACTION_DOWN:
         switch (v.getId()) { // Which button?
            case R.id.cnotebutton: // The upArrow
                Log.i("C", "C");
              //  mSoundPool.stop(mStream1);
                //mStream1= mSoundPool.play(mSoundPoolMap.get(1), streamVolume, streamVolume, 1,0, 1f);
                break;
            case R.id.dnotebutton: // The downArrow
                  Log.i("D", "D");
                 // mSoundPool.stop(mStream2);
                //mStream2= mSoundPool.play(mSoundPoolMap.get(2), streamVolume, streamVolume, 1,0, 1f);
                break;
            default:
            }

            break;
        case MotionEvent.ACTION_UP:

            break;  
        case MotionEvent.ACTION_POINTER_DOWN:
             switch (v.getId()) { // Which button?
                case R.id.cnotebutton: // The upArrow
                    Log.i("C", "C");
                  //  mSoundPool.stop(mStream1);
                    //mStream1= mSoundPool.play(mSoundPoolMap.get(1), streamVolume, streamVolume, 1,0, 1f);
                    break;
                case R.id.dnotebutton: // The downArrow
                      Log.i("D", "D");
                     // mSoundPool.stop(mStream2);
                    //mStream2= mSoundPool.play(mSoundPoolMap.get(2), streamVolume, streamVolume, 1,0, 1f);
                    break;
                default:
                }
            break;
        case MotionEvent.ACTION_POINTER_UP:

            break;
        case MotionEvent.ACTION_MOVE:

            break;
        default:

    }
    return true;
}

这没用。我应该如何解决这个问题？另一个问题，如果我在屏幕上移动手指，我想在手指到达按钮时按下按钮而不抬起它。ACTION_MOVE 也不起作用。抱歉这个愚蠢的问题我在这个领域很初学者。

更新

使用此代码，它可以检测到多点触控，但我总是得到两个相同的日志，就好像我用两根手指总是触摸同一个按钮一样。因此，即使我同时按下两个按钮，我得到一个日志“C”和另一个错误的“C”，我应该得到 C 和 D。

感谢提前！

你的代码看起来像这样吗？我强调了一些关键点

包be.domore.smokesignaltest；

导入android.app.Activity；导入android.os.Bundle；导入 android.view.MotionEvent；导入android.view.View；导入 android.view.View.OnTouchListener；导入android.widget.Button；

公共类 DummyActivity 扩展 Activity 实现 OnTouchListener { private Button myButton1; 私人按钮 myButton2;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Set the content view
    setContentView(R.layout.activity_dummy);

    // Map controls
    mapControls();
}

private void mapControls() {
    myButton1 = (Button) findViewById(R.id.myButton1);
    myButton1.setOnTouchListener(this);

    myButton2 = (Button) findViewById(R.id.myButton2);
    myButton2.setOnTouchListener(this);
}

public boolean onTouch(View v, MotionEvent event) {
    **if (event.getAction() == MotionEvent.ACTION_DOWN)**
        switch (v.getId()) {
        case R.id.myButton1:
            // TODO: put your code here
            **return true;**
        case R.id.myButton2:
            // TODO: put your code here
            **return true;**
        }

    *return false;*
}

}

以下类是我创建的用于管理声音的助手。有趣的部分是函数 AssignSoundToView。不知道对你有没有帮助？

你在玩 SurfaceView 吗？我感觉不是。为什么不简单设置每个Button的OnClickListener呢？

否则，您需要分别访问每个触摸事件：请参阅http://android-developers.blogspot.be/2010/06/making-sense-of-multitouch.html上的“索引与 ID”段落：也许会有所帮助你
