android – 防止周末发生重复闹钟

我已经把代码封锁了周末的闹钟到AlarmReceiver.java.

>我不知道AlarmReceiver.java是否是在周末放置警报的代码的正确位置.
>我不知道我正在使用的代码在周末阻止闹钟是正确的.基本上我告诉AlarmReceiver如果今天是星期六或星期天什么都不做.否则,消除警报.

AlarmActivity.java代码设置闹钟：

//Set a one time alarm
            if (repeatInterval == 0) {
                    alarmManager.set(AlarmManager.RTC,alarmTime.getTimeInMillis(),pendingIntent);
                    AlarmReceiver alarmReceiver = new AlarmReceiver(this); //https://stackoverflow.com/questions/16678763/the-method-getapplicationcontext-is-undefined

                    Toast.makeText(AlarmActivity.this,"Your one time reminder is Now set for " + hourSet + ":" + minuteSetString + amPmlabel,Toast
                            .LENGTH_LONG)
                            .show();
            }

            //Set a repeating alarm
            else {
                alarmManager.setRepeating(AlarmManager.RTC,repeatIntervalMilliseconds,pendingIntent);
                AlarmReceiver alarmReceiver = new AlarmReceiver(this); //https://stackoverflow.com/questions/16678763/the-method-getapplicationcontext-is-undefined

                    Toast.makeText(AlarmActivity.this,"Your reminder is Now set for " + hourSet + ":" + minuteSetString + amPmlabel + " and will " +
                            "repeat " +
                            "every " +
                            repeatInterval + " minutes.",Toast.LENGTH_LONG).show();
        }
