    i am getting an error as no such Column  : "here whatever i have entered in the row id" how to solve this error

  3. Jarek Magulski Avatar

    If you keep getting one row after typing various row ID's check if your line:
    …..KEY_ROWID + "=" + l, null……
    contains the lowercased letter L after "=" +, instead of what I had at first, which was the number '1'

    hope this helped

    when i try a certain row ID it gets its data, but the next time with any ID it gets nothing and keep the last data !!
    did any one face this problem ?

    same here! -.-

    Also, if row id is unique and if the cursor finds that row, that will be the only row retrieved hence no need to move to first row. Am I missing something?

    still didn't got why are u using c.moveToFirst(); before reading the entry. Will that not set the cursor again to the first row…???

    How would someone do this with a web page. display information more smooth like this rather than in webview

  10. Mikhail Berezovskiy Avatar

    In that case the simplest way is to do like this:
    if (c.moveToFirst()) {
    hotness = c.getString(c.getColumnIndex(KEY_HOTNESS));
    c.close();
    }

    moveToFirst() – return false if there is no any data.

    And we also need to close cursor.

    how to merge this thing with the internet??

  12. Shawnecy Avatar

    Alternatively, you can also use:
    if (cursor != null && cursor.moveToFirst())

    Cursor c = ourDataBase.query(DATABASE_TABLE, KEY_NAME, null, null, null, null,
    null);
    that way we don't need to create the String Array, almost the same but in my cel with 30Mb of ram every byte counts

    @hamisym poor me,
    at KEY_ROWID + "=" + id in getname() and gethotness() methods
    I used "-" instead of "=". Time to bed now :))

    mine always returns the 1st row in database, still don't know how to fix >-(

  17. stri8ted Avatar

    You can prevent the error when imputing a nonexistent row, by switch the if c!=null to if (c!= null && c.getCount()>0)

    I fucking got the idea! I did GetDataById and used bundle! 🙂

    Travis, how would you program a selection not according to the I'd but a touch to the row
