android - AutoCompleteTextView Not Working Properly on adding data from Database -

-

i have autocompletetextview works fine when define string statically this..

private string names[] = {"hassan", "usman", "kristen stewart"};

then this..

  arrayadapter<string> adapter = new arrayadapter<string>             (this, android.r.layout.select_dialog_item, names);     //getting instance of autocompletetextview      catgnames.setthreshold(0);//will start working 0 character     catgnames.setadapter(adapter);//setting adapter data autocompletetextview

but when try load data sqlite, drop down suggestion doesn't work. i'm doing this..

  categories = new string[100]   int =0;   databasehandler db = new databasehandler(this);     list<entries> entries1 = db.getcategories();     (entries cn : entries1) {         log.i("", cn.getcategories());          names[i] = cn.getcategories();         i++;     }

and after define adapter..

    arrayadapter<string> adapter = new arrayadapter<string>             (this, android.r.layout.select_dialog_item, names);     //getting instance of autocompletetextview      catgnames.setthreshold(0);//will start working 0 character     catgnames.setadapter(adapter);//setting adapter data autocompletetextview

this doesn't work. there no error or warning in log-cat..

i wondering why pass categories in arrayadapter while adding values names[]? should 'names' instead of 'categories' in arrayadapter, 

arrayadapter<string> adapter = new arrayadapter<string>         (this, android.r.layout.select_dialog_item, names);

or can create list, add db column values , pass them in arrayadapter. hope helps!
