Checkout the code below,

public class MainActivity extends AppCompatActivity implements View.OnClickListener {

private CheckBox cbDineIn;
private CheckBox cbTakeOut;
private CheckBox cbDelivery;

private Button btnDone;

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

private void initUI(){

    cbDineIn =(CheckBox)findViewById(R.id.cbDineInActivityMain);
    cbTakeOut =(CheckBox)findViewById(R.id.cbtakeOutActivityMain);
    cbDelivery =(CheckBox)findViewById(R.id.cbDeliveryActivityMain);
    btnDone=(Button)findViewById(R.id.btnDoneActivityMain);

    btnDone.setOnClickListener(this);
}

private JSONObject generateJSON(){
    JSONObject jsonObjectChoices = new JSONObject();
    try {
        if(cbDineIn.isChecked()){
            jsonObjectChoices.put("Dine-In","YES");
        }else {
            jsonObjectChoices.put("Dine-In","NO");
        }
        if(cbTakeOut.isChecked()){
            jsonObjectChoices.put("Take-Out","YES");
        }else {
            jsonObjectChoices.put("Take-Out","NO");
        }
        if(cbDelivery.isChecked()){
            jsonObjectChoices.put("Delivery","YES");
        }else {
            jsonObjectChoices.put("Delivery","NO");
        }
    } catch (JSONException e) {
        e.printStackTrace();
    }
    return jsonObjectChoices;
}

@Override
public void onClick(View v) {
    generateJSON();
}
}

Better you can set unique tag or id to your each CheckBoxes and then you can get the id or tag when you click the button.

Set those values in JSON and send.

To understand about JSON, you have lot of opportunities.

Your question is not clear enough

In android, if you need to generate JSON

try this one

CheckBox checkBox;

checkBox = (CheckBox) findViewById(R.id.checkbox);
checkBox.setOnClickListener(new View.OnClickListener(){
@override
public void onClick(){
String jsonObject = generateJSONData();
Log.i("Json Data", jsonObject);
}

}

public String generateJSONData(){
    JSONObject jsonObj = new JSONObject();
    jsonObj.put("name","ajay");
    jsonObj.put("address","fairfield");

    return jsonObj.toString();
    }
}

This code will generate JSON on CheckBox click.

The output will be

{ name:"ajay", address:"fairfield" }

I just write this code. I didn't test it. Hope it helps you :)
