如何在回收站视图中为多按钮设置onclick

Question

我是新手，我想实施一个简单的项目来学习。但是我很难实现This photo shows 12 of the 240 buttons I made with recyclerview

此回收者视图创建一个级别列表，每个级别具有不同的信息我想在级别按钮上设置onclick，我尝试为此使用一个界面。但是onclick设置为所有recyclerview项，并且无法识别按钮

您为clickListener中的任何按钮设置了onBindViewHolder()：

@Override
public void onBindViewHolder(MyViewHolder holder, int position) {
holder.Bindlevels(levels.get(position));
holder.setIsRecyclable(false);


//here

//on click button level1

holder.level1.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v){

//do something
}
});



//on click button level2


holder.level2.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v){

//do something
}
});



//on click button level3


holder.level3.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v){

//do something
}
});

//do the rest .............

}
