事件传递的总结图

处理特殊图形点击事件的几种方式 :

通过path绘制特殊的点击范围, 放入Region中 然后通过contains是否包含即可

public boolean isEventInPath(int xPos, int yPos) {
    // 判断手指是否在字幕框内
    RectF r = new RectF();
    Path path = new Path();
    path.moveTo(x,y);
    path.lineTo(x,y);
    ...
    path.close();
    path.computeBounds(r, true);
    Region region = new Region();
    region.setPath(path, new Region((int) r.left, (int) r.top, (int) r.right, (int) r.bottom)); //path与正切矩形做 交集，最后就是编程path的region
    return region.contains(xPos, yPos);
}

兼容onClick1:

 @Override
    public boolean dispatchTouchEvent(MotionEvent event) {
        return isEventInPath(event)?super.dispatchTouchEvent(event);
    }

兼容onClick2:

1
2
3
4
@Override
   public boolean onTouchEvent(MotionEvent event) {
       return isEventInPath(event)?super.onTouchEvent(event):false;
   }

自己的回调监听:

 @Override
    public boolean onTouchEvent(MotionEvent event) {
    switch (event.getActionMasked()) {
        mListener.onCenterCliched();//
     }
     return true;
    }


   	// 点击事件监听器
    public interface MenuListener {
        void onCenterCliched();
        }
