Completing UI Activity assignment

I have a UI Lab for Android Programming that I'm trying to complete. I think I'm close, yet so far away. I have four activities that I'm working with but only three of them needed worked on. Here is what I have. I need help with what I'm missing. Here's the first Activity which is AddToDoActivity ``` package course.labs.todomanager; import java.util.Calendar; import java.util.Date; import android.app.Activity; import android.app.DatePickerDialog; import android.app.Dialog; import android.app.DialogFragment; import android.app.TimePickerDialog; import android.content.Intent; import android.os.Bundle; import android.util.Log; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.DatePicker; import android.widget.EditText; import android.widget.RadioButton; import android.widget.RadioGroup; import android.widget.TextView; import android.widget.TimePicker; import course.labs.todomanager.ToDoItem.Priority; import course.labs.todomanager.ToDoItem.Status; public class AddToDoActivity extends Activity { // 7 days in milliseconds - 7 * 24 * 60 * 60 * 1000 private static final int SEVEN_DAYS = 604800000; private static final String TAG = "Lab-UserInterface"; private static String timeString; private static String dateString; private static TextView dateView; private static TextView timeView; private Date mDate; private RadioGroup mPriorityRadioGroup; private RadioGroup mStatusRadioGroup; private EditText mTitleText; private RadioButton mDefaultStatusButton; private RadioButton mDefaultPriorityButton; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.add_todo); mTitleText = (EditText) findViewById(R.id.title); mDefaultStatusButton = (RadioButton) findViewById(R.id.statusNotDone); mDefaultPriorityButton = (RadioButton) findViewById(R.id.medPriority); mPriorityRadioGroup = (RadioGroup) findViewById(R.id.priorityGroup); mStatusRadioGroup = (RadioGroup) findViewById(R.id.statusGroup); dateView = (TextView) findViewById(R.id.date); timeView = (TextView) findViewById(R.id.time); // Set the default date and time setDefaultDateTime(); // OnClickListener for the Date button, calls showDatePickerDialog() to show // the Date dialog final Button datePickerButton = (Button) findViewById(R.id.date_picker_button); datePickerButton.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { showDatePickerDialog(); } }); // OnClickListener for the Time button, calls showTimePickerDialog() to show // the Time Dialog final Button timePickerButton = (Button) findViewById(R.id.time_picker_button); timePickerButton.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { showTimePickerDialog(); } }); // OnClickListener for the Cancel Button, final Button cancelButton = (Button) findViewById(R.id.cancelButton); cancelButton.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { log("Entered cancelButton.OnClickListener.onClick()"); //TODO - Implement onClick().
