32.7 Modifying the Fragment

The fragment class now needs to be updated to react to button clicks and to interact with the data values stored in the ViewModel. The class will also need references to the three views in the user interface layout to react to button clicks, extract the current dollar value and to display the converted currency amount. With the MainFragment class file loaded into the code editor, modify the onActivityCreated() method to obtain and store references to the three view objects as follows:

.

.

import android.widget.Button;

import android.widget.EditText;

import android.widget.TextView;

 

import com.ebookfrenzy.viewmodeldemo.R;

 

public class MainFragment extends Fragment {

 

    private MainViewModel mViewModel;

    private EditText dollarText;

    private TextView resultText;

    private Button convertButton;

.
