简单例子了解View的事件分发(5)

可以看出没有打印出viewTest的onTouchEvent日志，证明确实没有调用，现在设置返回为false, onTouchEvent被调用的日志会出现，受限于篇幅，结果就不放出来了。
接下来，我们在ViewTest的onTouchEvent中设置一个点击监听，查看一些好玩的东西。首先，我先设置我们的ViewTest为可点击，viewTest的onTouch返回值也是false，然后我们看一下onTouchEvent代码：

@Override public boolean onTouchEvent(MotionEvent event) { Log.e("ViewTest","View onTouchEvent" + event.getAction()); Log.e("More","我被调用"); setOnClickListener(new OnClickListener() { @Override public void onClick(View view) { Log.e("ViewTest","原来中弹的不是我"); } }); return false; }

这时点击我们的viewTest，我们发现他竟然没有点击事件的日志。这是因为我们直接返回的false，截断了后面的点击事件的触发，所以决定什么都不做，采用默认的实现，即

return super.onTouchEvent(event);

神奇的事情发生了，出现了该有的点击效果。我们查看Log
