我有两个按钮，如果按下它们会发出声音。我想同时按下两个声音同时听到这两个声音。到目前为止：
@覆盖 //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;
}
它不起作用。我该怎么解决这个问题？如果我在屏幕上移动手指的另一个问题我想在我的手指到达按钮时按下按钮而不抬起它。 ACTION_MOVE也可以。对不起这个愚蠢的问题，我在这个领域非常初学。
更新
使用此代码可以检测到多点触控，但我总是有两个相同的日志，好像我用两个手指触摸了相同的按钮。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“C”错误，我应该得到C和D.
感谢您提前！

你在玩SurfaceView吗？我感觉不是。你为什么不简单地设置每个Button的OnClickListener？
否则，您需要单独访问每个触摸事件：请参阅http://android-developers.blogspot.be/2010/06/making-sense-of-multitouch.html处的“索引与ID”段落：也许它会对您有所帮助

你的代码看起来像这样吗？我强调了一些关键点
包be.domore.smokesignaltest;
import android.app.Activity; import android.os.Bundle; import android.view.MotionEvent; import android.view.View; import android.view.View.OnTouchListener; import android.widget.Button;
公共类DummyActivity扩展Activity实现OnTouchListener { 私人按钮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;**

以下类是我为管理声音而创建的帮助程序。有趣的部分是AssignSoundToView函数。我不知道它对你有帮助吗？
