深入浅析Android项目中的View事件分发机制-创新互联

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);
  }

}
