android 限制某个操作每天只能操作指定的次数

最近有个需求，要求启动页的拦截页每天只能显示3次，超过三次就显示别的页面，然后到第二天才可以再次显示，利用SharePreferences保存天数和每天的次数，大概是思路是：判断 如果是同一天，就去拿保存的次数，当次数小于3才执弹出拦截页，然后，每次弹出，次数就加1,并且保存次数和当天的时间；如果不是同一天，就把次数赋值为1，并且把当天赋值给最后访问的时间，然后保存当前的次数。具体实现如下：

 

package com.example.demo1.test;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;

import com.example.demo1.R;

import java.util.Calendar;

public class TwoActivity extends AppCompatActivity {
    private static final String TAG = "TwoActivity";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_two);
        findViewById(R.id.test).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                int frequency =   SharePreferencesUtils.getIntValue(TwoActivity.this,"time_and_frequency","frequency");
                int today = Calendar.getInstance().get(Calendar.DAY_OF_YEAR);
                int lastDay = SharePreferencesUtils.getIntValue(TwoActivity.this,"time_and_frequency","lastDay");
                Log.i(TAG, "onClick-----: "+"today:"+today);
                Log.i(TAG, "onClick-----: "+"lastDay:"+lastDay);
                Log.i(TAG, "onClick-----: "+"frequency:"+frequency);
                if(today != lastDay)
                {
                     //TODO执行拦截页操作；

                    //修改SharePreferences日期为当前日期，并记录次数一次；
                    frequency = 1;
                    Log.i(TAG, "onClick-----: "+"不是同一天执行次数"+frequency);
                    //把today赋值给lastDay  让today == lastDay
                    SharePreferencesUtils.putIntValue(TwoActivity.this,"time_and_frequency","lastDay",today);
                    SharePreferencesUtils.putIntValue(TwoActivity.this,"time_and_frequency","frequency",frequency);
                }else if(today == lastDay){
                    if(frequency < 3) {
                        //TODO执行拦截页操作；

                        Log.i(TAG, "onClick-----: "+"同一天执行次数"+frequency);
                        frequency++;
                        SharePreferencesUtils.putIntValue(TwoActivity.this,"time_and_frequency","lastDay",lastDay);
                             SharePreferencesUtils.putIntValue(TwoActivity.this,"time_and_frequency","frequency",frequency);
                    }else {
                        //TODO执行别的操作

                        Log.i(TAG, "onClick-----: "+"超过三次");
                    }
                }

            }
        });
    }

}
