} The problem here is that on the textview is displayed only two ids. The last one and the current. I want to show all the ids as far as the user wants. Not infinite of course. So how can i create an arraylist, lets say with ten values, and store the id each time?

• android
• database
• arraylist

You are adding only two IDs in your list so the behavior is correct. If your activity is created multiple times and you want to use the values added last time, 2 things must be done:

• declare the list as a static member:

  static ArrayList idList;

• change the way you allocate it like this:

  if (idList == null) { idList = new ArrayList(); }

This will do what you want. I would recommend not starting the activity again and just update the text in TextView when the buttons are clicked.

EDIT------

To update the TextView instead of starting the activity again do like this:

score.setText(score.getText().toString() + ", " + ID)

I just added a comma and the new id to the end of the existing text. Of course, you might want to format it differently. Having the displayed text and the new one should be good enough to get the desired format.
