How to insert value of multiple checkbox in mysql database in android?

i have a list of textview and checkbox. there is a spinner in the activity. according to spinner data the is fetched form the database. when the list is displayed, user checks the checkboxs in the listview. when multiple checkboxs are selected, the selected data should be stored in mysql database. i have adapter class to get the data form database. but unable to store the selected data from listview.

any help would be appreciated. thank u.

public class CallplanActivity extends Activity implements
    OnItemSelectedListener {

CheckBox chbk;

ListView lv;

Context context;

Spinner city;

ImageButton done;

JSONArray doctors_info;

ListView listview;
ListViewAdapter adapter,adaper2;

String cityselected;

             for (int i = 0; i < checked.size(); i++) {
