1. 第一層觸摸事件-Activty

public class MainActivity extends Activity {@Overridepublic boolean onTouchEvent(MotionEvent event) {return mGameView.onTouchEvent(event);}

2. 第二層觸摸事件-GameView

public class GameView extends SurfaceView implements SurfaceHolder.Callback, Runnable {@Overridepublic boolean onTouchEvent(MotionEvent event) {for (BaseModel model : gameLayout2) {// 是否實現了TouchAble接口if (model instanceof TouchAble) {// 事件傳遞給具體卡片if (((TouchAble) model).onTouch(event)) {// true 表示觸摸事件到此為止不再響應return true;}}}return false;}

3. 第三層觸摸事件-具體卡片

public class SeedFlower extends BaseModel implements TouchAble {// 觸摸區域private Rect touchArea;public SeedFlower(int locationX, int locationY) {this.locationX = locationX;this.locationY = locationY;this.isLive = true;touchArea = new Rect(locationX, locationY, locationX + Config.seedFlower.getWidth(), locationY + Config.seedFlower.getHeight());}@Overridepublic boolean onTouch(MotionEvent event) {int x = (int) event.getX();int y = (int) event.getY();// x,y坐標是否在觸摸區域if (touchArea.contains(x, y)) {Log.d("sufadi", "touch seed flower");return true;}return false;}
