最近有个需求，限制广告页每天只显示三次，我的思路是：如果似乎同一天，假如次数小于三，就显示广告页，次数+1，然后用SharePreferences保存时间和次数，如果不是同一天，次数就为0，然后操作跟上次一样，但总觉得哪里不太对，所以没有达到效果，求指教，以下是代码：
int frequency = SharePreferencesUtils.getIntValue(mContext,"time_and_frequency","frequency");
int lastDay = SharePreferencesUtils.getIntValue(mContext,"time_and_frequency","lastDay");
int today = Calendar.getInstance().get(Calendar.DAY_OF_YEAR);
Log.i(TAG, "date____today: "+today);
Log.i(TAG, "date____lastDay: "+lastDay);
Log.i(TAG, "date____get_frequency: "+frequency);
if (lastDay == 0 ||lastDay != today){
int new_frequency = SharePreferencesUtils.getIntValue(mContext,"time_and_frequency","new_frequency");
Log.i(TAG, "date____get_new_frequency: "+new_frequency);
if(new_frequency < 3){
new_frequency ++;
//显示广告页
int day = Calendar.getInstance().get(Calendar.DAY_OF_YEAR);
Log.i(TAG, "date____get_new_frequency++: "+new_frequency);
SharePreferencesUtils.putIntValue(mContext,"time_and_frequency","new_frequency",new_frequency);
SharePreferencesUtils.putIntValue(mContext,"time_and_frequency","lastDay",day);
}else{
//别的操作
}
}else {
if(frequency < 3){
frequency ++;
//显示广告页
int day = Calendar.getInstance().get(Calendar.DAY_OF_YEAR);
Log.i(TAG, "date____sameday_frequency: "+frequency);
SharePreferencesUtils.putIntValue(mContext,"time_and_frequency","frequency",frequency);
SharePreferencesUtils.putIntValue(mContext,"time_and_frequency","lastDay",day);
}else{
//别的操作
}
}
