Android creating button programmatically issue

Question

i'm trying to create buttons programmatically on my android application depending on how many items I have on my sqlite database. The buttons are there, but my problem is to set onClick on every button because I want to show different content when user's click the buttons. I'm using this code for now :

   for(cursorCol.move(0); cursorCol.moveToNext(); cursorCol.isAfterLast()){
          Id = Integer.parseInt(cursorCol.getString(cursorCol.getColumnIndex("id")));
          Log.i("Id","Id : "+Id);
                titleButton = cursorCol.getString(cursorCol.getColumnIndex("title"));
             Log.i("titleButton","titleButton : " + titleButton);
             elemOrder1 = Integer.parseInt(cursorCol.getString(cursorCol.getColumnIndex("elemOrder")));
               Log.i("elemOrder1 ","elemOrder1 : " + elemOrder1 );    

               btn = new Button(this); 
                  btn.setText("  " + titleButton + "  "); 
                  btn.setId(Id);
                  btn.setTextColor(Color.parseColor("#000000"));
                  btn.setTextSize(12);
                  btn.setPadding(10, 10, 10, 10);
                  btn.setBackgroundResource(R.drawable.gray_button);
                  btnlayout.addView(btn,params); 

                  btn.setOnClickListener(new View.OnClickListener() {

          @Override
          public void onClick(View v) {
           infoCard.removeAllViews();

           for(int i=0;i<=cursorCol.getCount();i++){

            Log.i("","titleButton : "+titleButton);

               }
          }
}

But the problem is that when I click the button it's showing only the last titleButton. Actually I don't need to show titleButton, I just did it for testing purposes. Any ideas how can I create different onClick methods for every single button?

I think the problem lies with this line of code:

btn = new Button(this);

You are editing the same button over and over again in your loop and not acutally creating a new one. To create a new one you will need to do this:

Button new_btn = new Button(this);

This will create a brand new one every time you iterate through your for loop.
