public class DoubleClickTest extends Activity {   String TAG = "DoubleClickTest";      private boolean waitDouble = true;   private static final int DOUBLE_CLICK_TIME = 350; //两次单击的时间间隔      @Override   public void onCreate(Bundle savedInstanceState){      super.onCreate(savedInstanceState);            // 设置布局文件，其中只有一个Button      setContentView(R.layout.double_click_test);            Button button = (Button)findViewById(R.id.button);      button.setOnClickListener(listener);   }         OnClickListener listener = new OnClickListener()   {      @Override      public void onClick(View v)       {         if ( waitDouble == true )          {            waitDouble = false;            Thread thread = new Thread() {               @Override               public void run() {                  try {                     sleep(DOUBLE_CLICK_TIME);                     if ( waitDouble == false ) {                        waitDouble = true;                        singleClick();                     }                  } catch (InterruptedException e) {                     e.printStackTrace();                  }               }            };            thread.start();         }          else {            waitDouble = true;            doubleClick();         }      }   };      // 单击响应事件   private void singleClick(){   Log.i(TAG, "singleClick");   }      // 双击响应事件   private void doubleClick(){   Log.i(TAG, "doubleClick");   }   }

缺点：用延时来确定双击，因为开了新的线程，对主线程UI操作不便
