获取系统设置好的闹钟时间

一开始的思路是通过android content provider获取

大部分手机系统，闹钟都被重新包装了一道，根本找不到的。

Uri uri = Uri.parse("content://com.android.alarmclock/alarm");
		Cursor c = context.getContentResolver().query(uri, null, null, null, null);
		if (c != null) {
		    if (c.moveToFirst()) {
		        do {
		            for (int j = 0; j < c.getColumnCount(); j++) {
		                Log.i(tag_alarm, c.getColumnName(j)
		                        + " which has value " + c.getString(j));
		            }
		        } while (c.moveToNext());
		    }
		    c.close();
		}　　

还会有可能出现如下错误：

google 了一翻。就是没找到解决之道

发现用如下方法可以直接取到下一个闹钟的时间

String str = Settings.System.getString(mActivityObject.getContentResolver(),
                        Settings.System.NEXT_ALARM_FORMATTED);
