java - ユーザーが選択した時間から通知を生成する方法

Question

何らかの通知を生成したい。この通知は、ユーザーが timePicker ダイアログで時間を設定したときに生成されます。これがシナリオです。ボタンをクリックすると、タイムピッカーダイアログが表示され、ユーザーは時間を選択できます..しかし、時間を設定したいときに、アプリが動かなくなり、強制的に閉じるように求められます..私が望むのはいつですかユーザーが設定した時刻を午後 10 時 45 分としましょう。ユーザーに通知するために午後 10 時 45 分に通知が生成されます。

これは私のTabTwoclassです：

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_tab_two);

    btnBrfkst = (Button) findViewById(R.id.button1);
    btnMtea = (Button) findViewById(R.id.button2);
    btnLunch = (Button) findViewById(R.id.button3);
    btnAftea = (Button) findViewById(R.id.button4);
    btnDinner = (Button) findViewById(R.id.button5);
    btnSupper = (Button) findViewById(R.id.button6);

    mCalen = Calendar.getInstance();
    hourOfDay = mCalen.get(Calendar.HOUR_OF_DAY);
    minute = mCalen.get(Calendar.MINUTE);
    ampm = mCalen.get(Calendar.AM_PM);

    btnBrfkst.setOnClickListener(this);
    btnMtea.setOnClickListener(this);
    btnLunch.setOnClickListener(this);
    btnAftea.setOnClickListener(this);
    btnDinner.setOnClickListener(this);
    btnSupper.setOnClickListener(this);
}

これは、通知を生成する AlarmReceiver クラスです

    private static final int MY_NOTIFICATION_ID=1;
     NotificationManager notificationManager;
     Notification myNotification;

     @Override
     public void onReceive(Context context, Intent intent) {
      Toast.makeText(context, "Time is set", Toast.LENGTH_LONG).show();

         Intent myIntent = new Intent(context, MainActivity.class);
         PendingIntent pendingIntent = PendingIntent.getActivity(
                context, 
                0, 
                myIntent, 
                Intent.FLAG_ACTIVITY_NEW_TASK);

         myNotification = new NotificationCompat.Builder(context)
           .setContentTitle("eMedicine")
           .setContentText("Time to take your medicine")
           .setTicker("Notification!")
           .setWhen(System.currentTimeMillis())
           .setContentIntent(pendingIntent)
           .setDefaults(Notification.DEFAULT_SOUND)
           .setAutoCancel(true)
           .setSmallIcon(R.drawable.ic_launcher)
           .build();

         notificationManager = 
           (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
         notificationManager.notify(MY_NOTIFICATION_ID, myNotification);
     }
}
