Android自定义可标记日历

1.前几天某某人要求我记住她什么时候洗的头发，然后记得提醒她，这么复杂的事情，我只好想着做个什么东西帮我，然后就这样了

2.先直接看看效果吧

初始情况

点击一个作为标记

再次点击后删除

3.这里还要感谢前辈的代码作为参考，毕竟以前也没有写过关于日历方面的东西，别人确实写得不错，我在原基础上加入了数据库操作等补充，以完成自己实际需求，作为尊重首先给出原作者的连接

就是这里–>http://blog.csdn.net/airsaid/article/details/52139045

4.然后贴出来关于数据库操作的代码，给大家作为参考

DatabaseHelper .Java 这是关于简单数据库操作的部分

package com.xugongming38.editcalendar.utils;import android.content.Context;import android.database.sqlite.SQLiteDatabase;import android.database.sqlite.SQLiteOpenHelper;/** * Created by dell on 2017/5/18. */public class DatabaseHelper extends SQLiteOpenHelper {    public static final String CREATE_DIARY = "create table Hair("            + "id integer primary key autoincrement, "            + "content text)";    private Context mContext;    public DatabaseHelper(Context context, String name, SQLiteDatabase.CursorFactory factory, int version){        super(context, name, factory, version);        mContext = context;    }    @Override    public void onCreate(SQLiteDatabase db) {        db.execSQL(CREATE_DIARY);    }    @Override    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {        db.execSQL("drop table if exists Hair");        onCreate(db);    }}

DataHelper .java 简化数据操作接口，避免直接操作数据库，做了再一层的封装，建议读者也这样做，可以让代码更清晰，更容易复用

package com.xugongming38.editcalendar.utils;import android.content.ContentValues;import android.content.Context;import android.database.Cursor;import android.database.sqlite.SQLiteDatabase;import java.util.ArrayList;import java.util.List;/** * Created by dell on 2017/5/18. */public class DataHelper {    public static DatabaseHelper mHelper;    public static void deleteData2List(String content) {        SQLiteDatabase dbDelete = mHelper.getWritableDatabase();        dbDelete.delete("Hair", "content = ?", new String[]{content});    }    public static void addData2List(String content) {        SQLiteDatabase db = mHelper.getWritableDatabase();        ContentValues values = new ContentValues();        values.put("content", content);        db.insert("Hair", null, values);        values.clear();    }    public static List<String> getDataList(Context context) {        if(mHelper==null){            mHelper = new DatabaseHelper(context, "Hair.db", null, 1);        }        List<String> dataList = new ArrayList<>();        SQLiteDatabase sqLiteDatabase = mHelper.getWritableDatabase();        Cursor cursor = sqLiteDatabase.query("Hair", null, null, null, null, null, null);        if (cursor.moveToFirst()) {            do {                String content = cursor.getString(cursor.getColumnIndex("content"));                dataList.add(content);            } while (cursor.moveToNext());        }        cursor.close();        return dataList;    }}
