Question

I have setup a SQLite database in my android application. I used a tutorial from google and my database works (I can put data in it and read it out in an other form). Now, I want to get the column price and put it in a graph. I can draw the graph already with hard coded values. I’m trying:

Cursor item0 = _dbHelper.fetcAllBoughtItems();
startManagingCursor(item0);
String xaxis[]=new String[4];
        xaxis[0]= item0.getString(item0.getColumnIndexOrThrow(databaseManager.KEY_BOUGHT_ITEM));
        xaxis[1]="2007";
        xaxis[2]="2008";
        xaxis[3]="2009";

I get the follow error (I know it’s telling me what’s wrong, but I can’t get it fixed)

04-27 10:03:21.382: ERROR/AndroidRuntime(6920): java.lang.RuntimeException: Unable to start activity ComponentInfo{Adforce.files/Adforce.files.summarySpendBudget}: android.database.CursorIndexOutOfBoundsException: Index -1 requested, with a size of 5

Can someone help me please?
Regards

Edit:
fetchAllBoughtItems() code is:
public Cursor fetchAllBoughtItems(){ //function to fetch all bought items
return mDb.query(DATABASE_TABLE_ItemB, new String[]{KEY_ROWID_ItemB, KEY_BOUGHT_ITEM, KEY_PRICE_ItemB }, null, null, null, null, null);
}

Answer 1

fetcAllBoughtItems() returns Cursor without column named databaseManager.KEY_BOUGHT_ITEM

fix fetcAllBoughtItems()

EDIT:

add item0.moveToFirst() before item0.getString(... and check if will return true
