I have a ListView that is populated with values from the mySQL database, and not all values are pulled, but those that match the specified condition: if (getHarakterByid (currCount) .equals ("Sale of monitors")). At the moment, in the listview element, one line together displays the position, code and address values, and only one address needs to be displayed. How can I do it? Tried SimpleAdapter, but nothing comes out.
