FinalDb操作sqlite的数据库(增删改查)

使用Stetho工具查看sqlite数据库，使用方法见：http://blog.csdn.net/u010002184/article/details/52563247

如下实例：

package com.example.liuyazhou.myfifthapplication;

import java.util.Date;
import java.util.List;

import net.tsz.afinal.FinalActivity;

import net.tsz.afinal.annotation.view.ViewInject;

import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import android.widget.Toast;

public class AfinalOrmDemoActivity extends FinalActivity {

    String TAG = AfinalOrmDemoActivity.class.getName();

    @ViewInject(id = R.id.textView)
    TextView textView; //这里使用了afinal的ioc功能
    @ViewInject(id = R.id.btn_add,click = "btnAddClick")
    Button btnAdd; //对象名没有用到，用到了click方法名
    @ViewInject(id = R.id.btn_delete,click = "btnDeleteClick")
    Button btnDelete;
    @ViewInject(id = R.id.btn_update,click = "btnUpdateClick")
    Button btnUpdate;

        setContentView(R.layout.activity_main);

    }//onCreate()
