Question

I tried this to get the count of rows. But the program is hanging.

private int countbaglist()
{
    int count = 0;
    SQLiteDatabase db = datasource.getWritableDatabase();
    Cursor cursor = db.rawQuery(
        "select count(*) from shoplist where itemname=?",
        new String[] { String.valueOf("itemname") });

    while(cursor.moveToFirst())
    {
        count = cursor.getCount();
    }
    return count;
}

Answer 1

It’s hanging because your while loop never exits. Replace the while with a one-time if check instead. Also, note that you need to read the integer value returned from the COUNT query, rather than the cursor’s row count which will always be 1.

if (cursor.moveToFirst())
    count = cursor.getInt(0);
