Question

I am using a SimpleCrusorAdaptor to display a list of items in a list view. When an item in listview is selected it starts an other activity, this activity changes the puzzle status which is shown in the list view. When this activity terminates and activity containing the list view again becomes active, list view shows the old status,

How can I ensure if the activity containing list view resumes, the cursor adapter updated the values ? Some thing to be done in onResume() of the cativity ?

private static String[] FROM = { PuzzleDatabase.KEY_PUZZLE_TITLE,
PuzzleDatabase.KEY_PUZZLE_STATUS };
private static int[] TO = { R.id.puzzle_title, R.id.puzzle_status };

 ListView  listView = (ListView) findViewById(R.id.puzzle_list);

 this.cursor = ps.puzzleDatabase.getPuzzleTitles();

 // Set up data binding
          SimpleCursorAdapter adapter = new SimpleCursorAdapter(this,
                R.layout.puzzle_list_row, cursor, FROM, TO);

    // Assign adapter to ListView
    listView.setAdapter(adapter);

Answer 1

for the updating values try doing this

class YourClass extends Activity{
   //other members
   private Bundle savedInstanceState;   //add this to your code
   public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    this.savedInstanceState = savedInstanceState;    //add this to your code

    //your other code here 
   }
    @Override
protected void onResume() {                     //add this function to your code
    datasource.open();                      //change datasource to your own database class's object
    super.onResume();
    onCreate(savedInstanceState);        
}

}
