深入浅析Android项目中的 View事件分发机制

本篇文章为大家展示了深入浅析Android项目中的 View事件分发机制，内容简明扼要并且容易理解，绝对能使你眼前一亮，通过这篇文章的详细介绍希望你能有所收获。

具体方法如下：

public class MyButton extends Button {  private final static String TAG = "MyButton::zjt";  public MyButton(Context context, AttributeSet attrs) {    super(context, attrs);    // TODO Auto-generated constructor stub  }  public MyButton(Context context, AttributeSet attrs, int defStyle) {    super(context, attrs, defStyle);    // TODO Auto-generated constructor stub  }  @Override  public boolean onTouchEvent(MotionEvent event) {    // TODO Auto-generated method stub    switch (event.getAction()) {    case MotionEvent.ACTION_DOWN:      Log.e(TAG, "onTouchEvent ACTION_DOWN");      break;    case MotionEvent.ACTION_MOVE:      Log.e(TAG, "onTouchEvent ACTION_MOVE");      break;    case MotionEvent.ACTION_UP:      Log.e(TAG, "onTouchEvent ACTION_UP");      break;    default:      break;    }    //return super.onTouchEvent(event);    return false;  }  @Override  public boolean dispatchTouchEvent(MotionEvent event) {    // TODO Auto-generated method stub    switch (event.getAction()) {    case MotionEvent.ACTION_DOWN:      Log.e(TAG, "dispatchTouchEvent ACTION_DOWN");      break;    case MotionEvent.ACTION_MOVE:      Log.e(TAG, "dispatchTouchEvent ACTION_MOVE");      break;    case MotionEvent.ACTION_UP:      Log.e(TAG, "dispatchTouchEvent ACTION_UP");      break;    default:      break;    }    return super.dispatchTouchEvent(event);  }}
