  • 0

In my application, after the user presses the appropriate button, an activity starts that creates a database with one table with two columns. The thing I can’t seem to get is: I would like one of the columns to automatically fill with the days of the week so that when I return a cursor over the database for the listActivity, the days are shown. I can get the database to build but I can’t seem to get the column to fill with the days. I tried this

public void installDays()
{
   String[] day = new String[7];;
   ContentValues initialValues = new ContentValues();
   day[0] = "Monday";
   day[1] = "Tuesday";
   day[2] = "Wednesday";
   day[3] = "Thursday";
   day[4] = "Friday";
   day[5] = "Saturday";
   day[6] = "Sunday";
   for(int i = 0; i < 7; i++)
   {
    initialValues.put(KEY_DAY, day[i]);
   }
 menuDb.insert(DATABASE_TABLE, null, initialValues);
 }

but that didn’t work. Then I tried this:

if(rowId == 0)
        {
            menuDbHelper.createMenu("Monday", "", "", "");
            menuDbHelper.createMenu("Tuesday", "", "", "");
            menuDbHelper.createMenu("Wednesday", "", "", "");
            menuDbHelper.createMenu("Thursday", "", "", "");
            menuDbHelper.createMenu("Friday", "", "", "");
            menuDbHelper.createMenu("Saturday", "", "", "");
            menuDbHelper.createMenu("Sunday", "", "", "");
            //menuDbHelper.installDays();
            rowId = 1;
        }

That works but its no good, if you hit the back button and come back to that activity it just adds them all over again and then I have fourteen days. What am I doing wrong here? I am new to Java so take it easy on me.

    You’re inserting records into your database every time you call that ListActivity. Do you have to use a database in this case? If you’re truly storing days of the week (assuming this isn’t an example), then you can simply store those values in an array that is initialized whenever that ListActivity is created. The docs state that the internal ListView in ListActivity can take an array as well as a cursor:

    ListActivity hosts a ListView object
    that can be bound to different data
    sources, typically either an array or
    a Cursor holding query results.
