Assinging The Values Of Cursor To Object

I'm working on showing list of contacts with checkbox. I tried implementing my own cursor adapter and it is checkable. But once I check that value I want the contacts to be stored

Solution 1:

Check this code. It worked for me. Best of luck.

Solution 2:

Here i changed little bit code of your adapter and activity. just look at it:

publicclassMainActivityextendsActivity  {

      private ArrayList<ContactPerson> arr;
        private Context context;
        private ListView list;
        private ContactArrayAdapter adapter;
        private String strName,strNumber;
        private View view;  
        publicstaticboolean[] arrBoolean = null;

        @OverridepublicvoidonCreate(Bundle savedInstance) {
            super.onCreate(savedInstance);
            setContentView(R.layout.activity_main);
            ProgressDialogpd=newProgressDialog(this);
            list = (ListView)findViewById(R.id.ListView2);
            arr = newArrayList<ContactPerson>();
            context = MainActivity.this;
            arr =  displayContacts();

            adapter = newContactArrayAdapter(this, R.layout.checkbox_item, arr);
            list.setAdapter(adapter);
        }

        public ArrayList<ContactPerson> displayContacts() {

            ContentResolvercr= getContentResolver();
            Cursorcur= cr.query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null);
            ContactPerson contact;
            if (cur.getCount() > 0) {
                while (cur.moveToNext()) {
                    contact = newContactPerson();

                    Stringid= cur.getString(cur.getColumnIndex(People._ID));
                    Stringname= cur.getString(cur.getColumnIndex(People.DISPLAY_NAME));
                    ContactPersoncp=newContactPerson();
                    cp.setName(name);
                    cp.setNumber(id);
                    cp.setSelected(false);
                    arr.add(cp);
                }
            }
            return arr;
        }

    //********* Adapter *****publicclassContactArrayAdapterextendsArrayAdapter<ContactPerson> {

    //  private final List<Contact> list;private Context context;

         publicContactArrayAdapter(Context context, int textViewResourceId,

                 ArrayList<ContactPerson> stateList) {
                 super(context, textViewResourceId, stateList);
                 this.list = newArrayList<ContactPerson>();
                 this.list.addAll(stateList);
                 }


        classViewHolder {

                viewHolder = newViewHolder();

                viewHolder.checkbox = (CheckBox) view.findViewById(R.id.contact_check);
                view.setTag(viewHolder);


            } else {

            }

            finalintpos= position;
