Question

我正在开发一个调度应用程序，其中用户从列表视图中选择时间，如下午9:30或列表中的任何时间点击按钮停止计划，我想要在9:30时停止计划9:30（我将在数据库中更新方法并更新用户结束时间）或用户从列表中选择的内容，用户也可以同时停止多个时间表，我尝试使用调度重复警报但没有找到任何解。请帮帮我，我该怎么做？。

这是我在特定时间发出警报的代码

  @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);

}

这是广播接收器的工作原理，但是当我在给定时间内没有给出报警时间表的时候，广播类触发。

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();
}

}

删除此行

calendar.setTimeInMillis(System.currentTimeMillis());

从代码..... Calendar.getInstance()已经是最新的。所以你有。

  @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);

在给定时间内停止计划
