Answer 1

Try this..

Your Activity must implements OnClickListener

Inside OnCreate()

    sweets.setOnClickListener(this); 
    patisserie.setOnClickListener(this); 

then after OnCreate()

@Override
public void onClick(View v) { 

    switch(v.getId()){
       case R.id.sweetsbuttonid:
         // do stuff related sweets click
         break;
       case R.id.patisseriebuttonid:
         // do stuff related patisserie click
         break;
     }

}

Answer 2

You can make a class that implements OnClickListener that you can accept a Intent parameter to with pre-set activity. THat way the parameter activity will be started but the listeners will all be instances of the same parent. No need to re-write code.
