第三次迭代感想

第三次迭代就顺利很多，我们组的分配量小很多，因为后面越来越去代码合成所以需要精力很多，之前所有的代码质量都需要保证好。这次我认领的任务是发现界面中功能实现，我做的是VIP实现功能。这个功能代码如下：

........

import android.app.Activity;
import android.database.sqlite.SQLiteDatabase;
import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.widget.TextView;

import com.edg.foodie.R;
import com.edg.foodie.controller.VipControllerActivity;
import com.edg.foodie.dao.DB;

import java.text.SimpleDateFormat;
import java.util.Date;

public class vipinfo extends Activity {

    Date date ;
    Date date1 ;
    SimpleDateFormat sdf;
    String  fdate = null;
    String  fdate1 = null;
    long ms ;

    String t = null;
    long time ;
    long totol;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.vipinfo);

        TextView kai_tv = (TextView) findViewById(R.id.kait);
        TextView start_tv = (TextView) findViewById(R.id.start);
        TextView end_tv = (TextView) findViewById(R.id.end);

        ms = System.currentTimeMillis();
        date = new Date (ms);
        sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        fdate = sdf.format(date);
        start_tv.setText("起始时间： "+fdate);

        /*t = search(name);*/
        t= String.valueOf(VipControllerActivity.flag);
        kai_tv.setText("开通时长： "+t+"个月");

        time = Long.parseLong(t);
        totol = ms + time * 30 * 24 * 3600000;
        fdate1 = sdf.format(totol);
        end_tv.setText("到期时间： "+fdate1);
    }

}
.........
这个代码是实现开通功能。这里面刚接触时候我都不会，然后去百度图书馆找资料才找到知识点，这个功能可以把开通时间分为三个等次，1个月，半年，和1年，
相应的费用也会有不同变化。会员特权可以免费配送，优先配送，优先制作等等。
