团队冲刺第十天

今天在昨天的基础上，增加了打卡的功能实现，点击打卡，显示打卡成功。根据不同时间段的日期，会有返回当前日期提醒。遇到的问题：当天打卡后，不可以时时更新显示在日历上，只有返回别的界面或者重选日期再次回到当前日期时才会显示打卡标志。计划明天完成这个功能。

相关代码：

package com.example.rili.sign;

import android.content.Context;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;


import java.util.ArrayList;

import java.util.List;


public class SignInHelper {

    private static final String TAG="SignInHelper--->>>";
    private SQLiteDatabase db;
    public SignInHelper(Context context){
        db=new LocalDbOpenHelper(context).getReadableDatabase();
    }

    public void insert(String signIn){
        String sql = "insert into signIn values('"+signIn+"')";
        db.execSQL(sql);
    }

    public List<String> query(int year,int month) {
        String mid = month > 9 ? "-" : "-0";
        String selection = "date like ?";
        String[] selectArgs = new String[]{"%" + year + mid + month + "%"};

        Cursor cursor = db.query("signIn",null,selection,selectArgs,null,null,null);
        List<String> result=new ArrayList<>();
        while (cursor.moveToNext()){
            String  date=cursor.getString(cursor.getColumnIndex("date"));
            result.add(date);
        }
            cursor.close();
        return result;
    }
}
