android SQLite数据库的增删改查以及事务的单元测试

核心提示：废话少说，为了这个数据库整理一两天的时间，android SQLite数据库的增删改查以及事务的单元测试，下面就把代码直接贴出来：创建androidproject 名称：db创建包名:com.gohighsoft.db新建一个Person实体类：package com.gohighsoft.db;public clas

废话少说，为了这个数据库整理一两天的时间，下面就把代码直接贴出来：

创建androidproject 名称：db

创建包名:com.gohighsoft.db

新建一个Person实体类：

package com.gohighsoft.db;

public class Person {

private Integer id;

private String name;

private Integer age;

public Person() {

};

public Person(String name, Integer age) {

this.name = name;

this.age = age;

}

public Integer getId(){

return id;

}

public void setId(Integer id) {

this.id = id;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public Integer getAge() {

return age;

}

public void setAge(Integer age) {

this.age = age;

}

public String toString() {

return "Person [age=" + age + ",id=" + id + ",name" + name + "]";

}

}

新建工具类：

DataBaseHaler.java

package com.gohighsoft.db;

import android.content.Context;

import android.database.sqlite.SQLiteDatabase;

import android.database.sqlite.SQLiteDatabase.CursorFactory;

import android.database.sqlite.SQLiteOpenHelper;

import android.util.Log;

public class DataBaseHaler extends SQLiteOpenHelper {

private static final String NAME = "sharp.db";// 。db可有可无

private static final int version = 1;// 版本号不能为0

public DataBaseHaler(Context context) {

super(context, NAME, null, version);

}

@Override

public void onCreate(SQLiteDatabase db) {

Log.i("aa","1111111111111");

db.execSQL("CREATE TABLE person(personid integer primary key
