Display Checkbox field from MySQL in Android

Question

I have a MySQL database that has some yes/no fields that are set up as TINYINT(1) in mysql. I'm displaying information from that table into a table layout on android. How do I get those fields to show as a checkbox in android since the values in those fields are 0 for no and anything except 0 for yes? Or is there a better way of doing this by changing the field type in mysql?

Here is my MainActivity.java in case you would like to see it. It currently is only displaying 3 text fields from the table.

public class MainActivity extends Activity {
 String data = "";
 TableLayout tl;
 TableRow tr;
 TextView label;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    tl = (TableLayout) findViewById(R.id.maintable);

    final GetDataFromDB getdb = new GetDataFromDB();
    new Thread(new Runnable() {
        public void run() {
            data = getdb.getDataFromDB();
            System.out.println(data);

            runOnUiThread(new Runnable() {

                @Override
                public void run() {
                    ArrayList<Users> users = parseJSON(data);
                    addData(users);
                }
            });

        }
    }).start();
}

public ArrayList<Users> parseJSON(String result) {
    ArrayList<Users> Suppliers = new ArrayList<Users>();
    try {
        JSONArray jArray = new JSONArray(result);
        for (int i = 0; i < jArray.length(); i++) {
            JSONObject json_data = jArray.getJSONObject(i);
            Users user = new Users();
     //       user.setId(json_data.getInt("id"));
            user.setDelivery_date(json_data.getString("Delivery_Date"));
            user.setOrder(json_data.getString("Order"));
            user.setHauler(json_data.getString("Haulers_HaulerID"));
            Suppliers.add(user);
        }
    } catch (JSONException e) {
        Log.e("log_tag", "Error parsing data " + e.toString());
    }
    return Suppliers;
}

void addHeader(){

Any suggestions appreciated.

You have a Users data object, so I think you should have a boolean property in the Users object, convert the JSON integer to boolean on parse, and use the boolean to set the checkbox:

class Users {

    .
    .
    .
    private boolean mFlag;

    public boolean isFlag() {
        return mFlag;
    }

    public void setFlag(boolean flag) {
        mFlag = flag;
    }

    .
    .
    .
}

parse:

 user.setFlag(json_data.getInt("Flag") != 0);

display:

CheckBox cbFlag = new CheckBox(activity);

cbFlag.setChecked(user.isFlag());
