You will be able to understand how to add a click to a recyclerview here: https://stackoverflow.com/questions/24471109/recyclerview-onclick — rlinoz, May 27 '20 at 20:58

You set the clickListener for any button in 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 .............

}

Thanks for taking the time to respond It works, but it's not, because it's not the job of the onBindViewHolder and the recyclerview, and it doesn't seem right to write this for 12 levels. — Shayan, May 28 '20 at 00:10
