推荐答案
此代码中的操作是您首先通过xml设置onClickListener来运行方法void KlickNo (View view)
what you do in this code is that you first set an onClickListener through the xml to run the methodvoid KlickNo (View view)
，然后通过设置new OnClickListener(){ blah,blah}代替以前的设置来取消所有这些操作
and then you cancel all this by setting a new OnClickListener(){ blah,blah} replacing the previous setting
您必须使用其中之一. xml OnCLickListener设置的OnClick调用KlickNo方法，因此直接在其中进行操作并删除.setOnClickListener(.....)声明
You either have to use one or the other. The KlickNo method is called by the OnClick of the set by xml OnCLickListener, so do your stuff directly there and delete the .setOnClickListener(.....) declaration
