...And if you want to retrieve the index of that button then use a map!

Map<View,Integer> buttonMap = new HashMap<View,Integer>();

Button addAsFriend[] = new Button[c.getCount()];

for( i=0;i<c.getCount();i++)
{
   Button btn = new Button(this);
   buttonMap.put(btn,i);

   btn.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {
         int index = buttonMap.get( v );

         // do something with index here

      }
   };);
   addAsFriend[i] = btn;
}

You can implement the OnClickListener Interface in you activity. Doing this you will have to override the onClick() method. Then you can pass the activity as an OnClickListener to each button.

public class YourActivity implements OnClickListener {

     public void onCreate(){
         ...

         Button addAsFriend[] = new Button[c.getCount()];
         for( i=0;i<c.getCount();i++)
         {
             addAsFriend[i] = new Button(this);
             ((Button)addAsFriend[i]).setOnClickListener(this);
         }    
        ...
    }

    public void onClick(View v){
        // Put your listener code here.
    }
}

Button addAsFriend[] = new Button[c.getCount()];
for( i=0;i<c.getCount();i++)
{
 addAsFriend[i] = new Button(this);
 ((Button)addAsFriend[i]).setOnClickListener(myclickListener);
}

       @Override

       }
     };);
