android - Android のカスタム カレンダーの通知

Question

学校のキオスク アプリケーションと統合したカスタム カレンダー アプリケーションがあります。カレンダーはイベントの追加を許可し、各イベントの通知を設定する必要があります。各イベントを保存し、設定された日時に通知するにはどうすればよいでしょうか? 誰でも私を助けることができますか？これがカレンダーコードです。

public class MyCalendar extends Activity implements OnClickListener {

public Calendar month;
public CalendarAdapter adapter;
public Handler handler;
public ArrayList<String> items;

    @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.calendar);

        month = Calendar.getInstance();
    items = new ArrayList<String>();
    adapter = new CalendarAdapter(this, month);

    GridView gridView = (GridView) findViewById(R.id.gridview);
    gridView.setAdapter(adapter);

    handler = new Handler();
    handler.post(calendarUpdater);

    TextView title = (TextView) findViewById(R.id.title);
    title.setText(android.text.format.DateFormat.format("MMMM yyyy", month));

    Button previous = (Button) findViewById(R.id.previous);
    previous.setOnClickListener(this);

    Button next = (Button) findViewById(R.id.next);
    next.setOnClickListener(this);

    gridView.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View v,
                int position, long id) {
            TextView date = (TextView) v.findViewById(R.id.date);
            if (date instanceof TextView && !date.getText().equals("")) {

                Intent intent = new Intent(
                        "com.gpplsmje.mac.calendar.CALENDAREVENTS");

                intent.putExtra(
                        "date",
                        android.text.format.DateFormat
                                .format("MMMM", month)
                                + " "
                                + day
                                + ", "
                                + android.text.format.DateFormat.format(
                                        "yyyy", month));
                startActivity(intent);
            }
        }
    });

public void refreshCalendar() {
    TextView title = (TextView) findViewById(R.id.title);
    daysAdapter.fill();
    adapter.refreshDays();
    adapter.notifyDataSetChanged();
    handler.post(calendarUpdater);
    title.setText(android.text.format.DateFormat.format("MMMM yyyy", month));
}

@Override
public void onNewIntent(Intent intent) {
    String date = intent.getStringExtra("date");
    String[] dateArr = date.split("-");
    month.set(Integer.parseInt(dateArr[0]),
            Integer.parseInt(dateArr[1], Integer.parseInt(dateArr[2])));
}

public Runnable calendarUpdater = new Runnable() {

    @Override
    public void run() {
        items.clear();
        for (int i = 0; i < 31; i++) {
            Random r = new Random();
            if (r.nextInt(10) > 6) {
                items.add(Integer.toString(i));
            }
        }
        adapter.setItems(items);
        adapter.notifyDataSetChanged();
    }

};

@Override
public void onClick(View v) {
    switch (v.getId()) {
    case R.id.previous:
        if (month.get(Calendar.MONTH) == month
                .getActualMinimum(Calendar.MONTH)) {
            month.set((month.get(Calendar.YEAR) - 1),
                    month.getActualMaximum(Calendar.MONTH), 1);
        } else {
            month.set(Calendar.MONTH, month.get(Calendar.MONTH) - 1);
        }
        refreshCalendar();
        break;
    case R.id.next:
        if (month.get(Calendar.MONTH) == month
                .getActualMaximum(Calendar.MONTH)) {
            month.set((month.get(Calendar.YEAR) + 1),
                    month.getActualMinimum(Calendar.MONTH), 1);
        } else {
            month.set(Calendar.MONTH, month.get(Calendar.MONTH) + 1);
        }
        refreshCalendar();
        break;
    }
}
}

CalendarAdapter クラスは次のとおりです。

public class CalendarAdapter extends BaseAdapter {

static final int FIRST_DAY_OF_WEEK = 0;

private Context context;

private java.util.Calendar month;
private Calendar selectedDate;
private ArrayList<String> items;

public String[] days;

public CalendarAdapter(Context c, Calendar monthCalendar) {
    month = monthCalendar;
    selectedDate = (Calendar) monthCalendar.clone();
    context = c;
    month.set(Calendar.DAY_OF_MONTH, 1);
    this.items = new ArrayList<String>();
    refreshDays();
}

public void setItems(ArrayList<String> items) {
    for (int i = 0; i != items.size(); i++) {
        if (items.get(i).length() == 1) {
            items.set(i, "0" + items.get(i));
        }
    }
    this.items = items;
}

@Override
public int getCount() {
    // TODO Auto-generated method stub
    return days.length;
}

@Override
public Object getItem(int arg0) {
