Unable to set only one checkbox selected in a listview

Question

I have a listview that each item in listview contains a checkbox. My problem is i want to set only one checkbox selected at a time. Another problem is when i select a checkbox in order 3, then when i scroll up and back, checkbox is checked in different order 5 or 8 randomly Could you help me solve this issue

Thisis because of the way in which listview recycling mechanism works. You need to post relevant adapter code — Raghunandan, Jul 27 '15 at 05:39
Probably what you want is a radio button rather than checkbox. Also, to get better response, post the relevant code. — Ganesh Kumar, Jul 27 '15 at 05:39
take a boolean in listview object for check and uncheck and change its value if checked true and false if uncheck and in place of taking android checkbox, use a checkbox image let's say checked.png and unchecked.png use it according to check status. — Sandeep Tiwari, Jul 27 '15 at 05:43
I know, every item when i scroll up and back, listview is redrawn. Do you know where i can get clear concept about it? — Farruh Habibullaev, Jul 27 '15 at 05:44

Set your listview to :

lvSelectLocation.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
ArrayAdapter<String> adptr = new ArrayAdapter<String>(Location.this, android.R.layout.simple_list_item_single_choice, locationList);

Handle onItemClick only :

lvSelectLocation.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                    long arg3) {
                    Selected = arg0.getItemAtPosition(arg2).toString();
            }
        });

Android automatically recycle the listview view so, selected option is recycle when you scroll. For that you have to set the selected list item to your ArrayList.

You can use the API demo to understand the best way for this implementation. Have a look on this. There is a CHOCIE_MODE option with the list view you can set it to CHOCIE_MODE_SINGLE. Simple code is like this-

public class List10 extends ListActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setListAdapter(new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_single_choice, GENRES));

        final ListView listView = getListView();
        listView.setItemsCanFocus(false);
        listView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
    }
    private static final String[] GENRES = new String[] {
        "Action", "Adventure", "Animation", "Children", "Comedy", "Documentary", "Drama",
        "Foreign", "History", "Independent", "Romance", "Sci-Fi", "Television", "Thriller"
    };
}
