我如何在服务中实现以下方法，我希望它每 1 分钟工作一次（如果对应于当前时间，代码是检查天小时 mint 做某事）我看到了很多问题但没有用，请帮助。谢谢

{String[] columns = new String[] { KEY_ROWID, KEY_chNAME, KEY_prNAME, KEY_Rerun, KEY_HOUR, KEY_MINUTE, KEY_SUN, KEY_MON, KEY_TUE, KEY_WED, KEY_THU, KEY_FRI, KEY_SAT }; 光标 c = ourdatabase.query(DATABASE_TABLE, columns, null, null, null,null, null); 字符串结果 = "";

    Calendar cl = Calendar.getInstance();
    int today = cl.get(Calendar.DAY_OF_WEEK);

    // String mStr="";
    // mStr=mStr.concat("<body>");
    // mStr=mStr.concat("<table border='1' ><tr> <th style='width:5px></th><td align='center'><b> Channal  </b></td><td align='center'><b>  Program  </b></td><td align='center'><b>  Time  </b></tr>");
    int iRow = c.getColumnIndex(KEY_ROWID);
    int iCh = c.getColumnIndex(KEY_chNAME);
    int ipr = c.getColumnIndex(KEY_prNAME);
    int iHr = c.getColumnIndex(KEY_HOUR);

使用 AlarmManager + IntentService 的组合。

使用警报管理器，您可以安排事件。IntentServices 是在后台线程中执行一次性任务的服务。它们的组合是执行预定作业的更直接的方式。
