在 Edittext 中输入 DateTime 后，如何为我的任务创建通知剩余

Question

大家早上好..我创建了 Android 应用程序来准备计划任务..对于我的任务我想为我的任务创建通知剩余部分..我没有任何编码来创建它...我在谷歌上搜索这个主题但是我没有得到任何适当的解决方案..请任何人帮助我...提前谢谢..

这是我的编码..用于在编辑文本框中插入日期时间：

MainActivity.java：

 EditText edtdate;
  private ImageButton ib;
    private Calendar cal;
    private int day ,month ,year;

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.add_inbox);
edtdate = (EditText) findViewById(R.id.edtdate);

cal = Calendar.getInstance();
        day = cal.get(Calendar.DAY_OF_MONTH);
        month = cal.get(Calendar.MONTH);
        year = cal.get(Calendar.YEAR);
     cal.add(Calendar.HOUR, heure);                         
        Intent intent1 = new Intent(this, MyBroadcastReceiver.class);                       
        PendingIntent sender = PendingIntent.getBroadcast(this, 0, intent1,   
      PendingIntent.FLAG_UPDATE_CURRENT);                       
        AlarmManager am = (AlarmManager) this .getSystemService(Context.ALARM_SERVICE);                         
        am.setRepeating(AlarmManager.RTC_WAKEUP, 
                cal.getTimeInMillis(), 
                heure*3600*1000,  sender);

      custom = new CustomDateTimePicker(this, new     
      CustomDateTimePicker.ICustomDateTimeListener() {
          @Override
          public void onSet(Dialog dialog, Calendar calendarSelected,
                  Date dateSelected, int year, String monthFullName,
                  String monthShortName, int monthNumber, int date,
                  String weekDayFullName, String weekDayShortName,
                  int hour24, int hour12, int min, int sec,
                  String AM_PM)
          {
              ((EditText) findViewById(R.id.edtdate))
                      .setText(calendarSelected
                                      .get(Calendar.DAY_OF_MONTH)
                              + "/" + (monthNumber+1) + "/" + year
                              + ", " + hour12 + ":" + min
                              + " " + AM_PM);
          }
          @Override
          public void onCancel() {
          }
      });
          }
      });
 custom.set24HourFormat(false);

        custom.setDate(Calendar.getInstance());

        findViewById(R.id.imageButton1).setOnClickListener(
                new OnClickListener() {

                    @Override
                    public void onClick(View v) {
                        custom.showDialog();
                    }
                });
}
  CustomDateTimePicker custom;

@odiiil 您可以使用警报管理器在特定日期时间安排通知

Answer 2

使用广播接收器创建通知：

public class MyBroadcastReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {

    Intent resultIntent = new Intent(context,
            MainActivity.class);

    resultIntent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);

    // Because clicking the notification opens a new ("special") activity,
    // there's no need to create an artificial back stack.
    PendingIntent resultPendingIntent = PendingIntent.getActivity(context,
            0, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);

    Notification.Builder mBuilder = new Notification.Builder(context)
    .setSmallIcon(R.drawable.courier_blanc)
    .setContentTitle("Title")
    .setContentText("Message");

    mBuilder.setAutoCancel(true);   
    mBuilder.setPriority(Notification.PRIORITY_MAX);
    mBuilder.setContentIntent(resultPendingIntent);

    // Sets an ID for the notification
    int mNotificationId = 001;
    // Gets an instance of the NotificationManager service
    NotificationManager mNotifyMgr = (NotificationManager) context
            .getSystemService(Application.NOTIFICATION_SERVICE);


    // Builds the notification and issues it.
    mNotifyMgr.notify(mNotificationId, mBuilder.build());

} }

说是否有帮助。如果您有一些问题或者不是您真正想要的，请说出来:)

编辑：

        int heure = 1;
        int minute = 30;
        Calendar cal = Calendar.getInstance();
        cal.add(Calendar.HOUR, heure); 
        cal.add(Calendar.MINUTE, minute);

        Intent intent = new Intent(this, MyBroadcastReceiver.class);

        PendingIntent sender = PendingIntent.getBroadcast(this, 0, intent,
                PendingIntent.FLAG_UPDATE_CURRENT);

        AlarmManager am = (AlarmManager) this
                .getSystemService(Context.ALARM_SERVICE);

        am.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), minute*60*1000+heure*3600*1000,  sender);
