Completing UI Activity assignment [closed]

Question

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;

    //TODO - Display Priority in a TextView

    final TextView priorityView = findViewByID(R.id.PriorityView);
    PriorityView.setToString();

    
    //TODO - Display Time and Date.

    } catch (InterruptedException e) {

Any thought on how to improve the cancelButton code in the AddToDoAcitivity?

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().  
        Intent intent = new Intent setResult;
        finish();
        
    }
});

Answer 1

change your AddToDoActivity code like this

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
