一招教你在android中玩轉sqlite

對於sqlite的使用僅僅封裝成一個類，目的就是爲了那些對於sqlite使用不太熟悉的人準備的，有此代碼在手，再也不怕玩不轉sqlite了。話不多說直接看代碼：

import android.content.ContentValues;
import android.content.Context;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
import android.util.Log;

import java.io.File;
import java.lang.reflect.Field;
import java.lang.reflect.Method;
import java.util.ArrayList;
import java.util.List;
