how to store values of checked check box in database mysql or sqlite any

I have created custom listview with image and text and check box. Now i want to store values of string array in database which are checked. I tried to store position of checked item in integer array and returned that array in activity but it's not working.

This the main activity

public class Industry extends AppCompatActivity {

    ListView listView;
    Toolbar toolbar;
    ArrayList<HashMap<String, Object>> topicname;
    ListTopic adapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_industry);

        toolbar = (Toolbar)findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        toolbar.setTitle("Industries");

        if (getSupportActionBar() != null) {
            getSupportActionBar().setDisplayHomeAsUpEnabled(false);
        }

        listView = (ListView)findViewById(R.id.listView);
        //these arrays are just the data that
        //I'll be using to populate the ArrayList
        //You can use our own methods to get the data
        String names[]={"Advanced Industries",
                "Automotive & Assembly",
                "Consumer & Retails",

        //Items in the ListView

        int noOfPlayers=names.length;

        //now populate the ArrayList players
        for(int i=0; i<noOfPlayers; i++)
        {
            temp=new HashMap<String, Object>();

            temp.put("name", names[i]);
            temp.put("photo", photos[i]);

            //add the row to the ArrayList
            topicname.add(temp);
        }

 /*create the adapter
 *first param-the context
 *second param-the id of the layout file
  you will be using to fill a row
 *third param-the set of values that
   will populate the ListView */
        adapter=new ListTopic(this, R.layout.list_adapter,topicname);

        //finally,set the adapter to the default ListView
        listView.setAdapter(adapter);

    }
