Ich denke du bist fast da. (PecLue Annahme, daß Ihr kleines Augenbild)

Pseudo-Code:

 holder.pecLue.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 

      //if(holder.pecLue.getVisibility()== View.VISIBLE) 
      // holder.pecLue.setVisibility(View.INVISIBLE); 

      if(conditionIfChapterIsMarked){ 
       holder.pecLue.setImageResource(R.drawable.pec_lue_icon_unmarked); 
       //unmarkChapterLogic() 
      }else{ 
       holder.pecLue.setImageResource(R.drawable.pec_lue_icon_marked); 
       //markChapterLogic() 
      } 
     } 
    });
