給定時間的停止時間表

Question

我正在開發一個時間安排應用程序，其中用戶從列表視圖中選擇一個時間，如下午9:30或列表中的任何時間點擊按鈕停止時間表，我想要停止時間表在9點半時9點30分（我將更新數據庫方法並更新用戶結束時間），或者用戶從列表中選擇的用戶也可以同時停止多個時間表，我嘗試使用調度重複警報但沒有找到任何解決方案。 請幫我，我該如何做到這一點？

這是代碼，我想提出警告的具體時間

@TargetApi(Build.VERSION_CODES.N) 
public void scheduleAlarm(View view, String timeEnd,String id) { 

    StringTokenizer tokens = new StringTokenizer(timeEnd, ":"); 
    String first = tokens.nextToken(); 
    String second = tokens.nextToken(); 

    StringTokenizer token = new StringTokenizer(second, " "); 
    String two = token.nextToken(); // just changing given time into like 9:30 to 9 and 30 

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

    android.icu.util.Calendar calendar = android.icu.util.Calendar.getInstance(); 
    calendar.setTimeInMillis(System.currentTimeMillis()); 
    calendar.set(android.icu.util.Calendar.HOUR_OF_DAY, Integer.parseInt(first)); 
    calendar.set(android.icu.util.Calendar.MINUTE, Integer.parseInt(two)); 

    Intent intent = new Intent(getApplicationContext(), AlarmReciever.class); 
    intent.putExtra("ID",id); 
    intent.putExtra("EndTime",timeEnd); 
    PendingIntent sender = PendingIntent.getBroadcast(getApplicationContext(), 0, intent, PendingIntent.FLAG_UPDATE_CURRENT); 
    am.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), sender); 

} 

這是廣播接收器的工作，但在同一時間播出的類扳機時，我給報警時間安排不是在給定的時間。

public class AlarmReciever extends BroadcastReceiver { 

@Override 
public void onReceive(Context context, Intent intent) { 
    SQLITEDBTABLE sqLiteDatabase = new SQLITEDBTABLE(context); 

    String id = intent.getStringExtra("ID"); 
    String time_end = intent.getStringExtra("EndTime"); 

    sqLiteDatabase.update(time_end, id); 
    /* sqLiteDatabase.deleteOlderData(laterId); 
    sqLiteDatabase.deleteInactive(laterId); 
    sqLiteDatabase.updateEmployee(laterId, "Inactive");*/ 
    //Toast.makeText(context, "Alarm Triggered and SMS Sent", Toast.LENGTH_LONG).show(); 
} 

}

刪除此行

calendar.setTimeInMillis(System.currentTimeMillis()); 

從代碼..... Calendar.getInstance()已經是最新的。所以你有了。

@TargetApi(Build.VERSION_CODES.N) 
    public void scheduleAlarm(View view, String timeEnd,String id) { 

     StringTokenizer tokens = new StringTokenizer(timeEnd, ":"); 
     String first = tokens.nextToken(); 
     String second = tokens.nextToken(); 

     StringTokenizer token = new StringTokenizer(second, " "); 
     String two = token.nextToken(); // just changing given time into like 9:30 to 9 and 30 

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

     android.icu.util.Calendar calendar = android.icu.util.Calendar.getInstance(); 

     calendar.set(android.icu.util.Calendar.HOUR_OF_DAY, Integer.parseInt(first)); 
     calendar.set(android.icu.util.Calendar.MINUTE, Integer.parseInt(two)); 

     Intent intent = new Intent(getApplicationContext(), AlarmReciever.class); 
     intent.putExtra("ID",id); 
     intent.putExtra("EndTime",timeEnd); 
     PendingIntent sender = PendingIntent.getBroadcast(getApplicationContext(), 0, intent, PendingIntent.FLAG_UPDATE_CURRENT); 
     am.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), sender);
