最近在做一个 小应用， 涉及到的跟以前接触的 不太一样。 这次是  onTouchEvent 和 OnGestureListener接口的 结合， 本身继承SurfaceView...

拿出来跟大家讨论一下 看看有没有更好的办法！自己定义了好多 flag， 自己总觉得有更简洁的办法。。。

上码吧！ 注释不多！重在意会蛤！

@Override	public boolean onTouchEvent(MotionEvent event) { 				int pointerCounter = event.getPointerCount();		int action = (event.getAction() & event.getActionMasked());		gd.onTouchEvent(event);		 		if( pointerCounter <= 2){			switch (action) {			case MotionEvent.ACTION_DOWN:				int X1 = (int) event.getX(0);				int Y1 = (int) event.getY(0);				this.checkCollection(X1, Y1);				tempForId [0] = currentBallId;				tempForCollision [0] = currentBallId;				Log.e(TAG, "first===getX(0)===getY(0)===>DOWN"  + X1 + ":" + Y1 + tempForCollision [0]);				if(touched){					longFlag = true;					secondTouched = false;					firstTouchenCanMove = true;				}								break;			case MotionEvent.ACTION_POINTER_DOWN:				int X2 = (int) event.getX(1);				int Y2 = (int) event.getY(1);				if(touched & (pointerCounter > 1) ){					this.checkCollection(X2, Y2);					tempForId [1] = currentBallId;					Log.d(TAG, "second===getX(1)===getY(1)===>DOWN"  + X2  + ":" + Y2);					secondTouched = true;				}else{					firstTouchenCanMove = false;					secondTouched = false;				}				longFlag = false;				break;			case MotionEvent.ACTION_MOVE:								if (firstTouchenCanMove) {					X1 = (int) event.getX(0);					Y1 = (int) event.getY(0);					this.touchMoveBalls(tempForId [0], X1, Y1);					this.tempMoveCollisionCheck(tempForCollision[0]);					Log.d(TAG, "first===getX(0)===getY(0)===>MOVE" + X1 + ":" + Y1);					if (secondTouched){						X2 = (int) event.getX(1);						Y2 = (int) event.getY(1);						this.touchMoveBalls(tempForId [1], X2, Y2);						Log.e(TAG, "second===getX(1)===getY(1)===>MOVE"  + X2 + ":" + Y2);					}else{						secondTouched = false;						touched = false;					}				}								longFlag = false;				afterMoveSendPdFlag = false;				break;			case MotionEvent.ACTION_POINTER_UP:				secondTouched = false;				touched = false;				longFlag = false;				firstTouchenCanMove = false;				break;			case MotionEvent.ACTION_UP:				secondTouched = false;				if (firstTouchenCanMove ) {					if(afterMoveSendPdFlag){						if(pdSendCheckForLongTouch){							this.sendToPd();							Log.i(TAG, "first pointer======>up, SEND pd");						}					}					touched = false;					afterMoveSendPdFlag = true;					longFlag = false;					pdSendCheckForLongTouch = true;					secondTouched = false;					firstTouchenCanMove = false;				}								break;			}// close events switch loop		}//end of if (pointerCounter <= 2)		return true; //return to void onTouchEvents()	}
