使用步骤如下

android studio中可以直接添加依赖：

// litepal数据库

compile ‘org.litepal.android:core:1.6.1’

下面的操作eclipse和android studio都是一样的了。

eclipse中在项目中新建libs文件夹，把jar包行进去：

新建assets目录，然后创建 litepal.xml资源文件，用于创建数据库名称、数据库版本、表名、数据库存放的位置；

<?xml version="1.0" encoding="UTF-8"?>

页面activity_main.xml，就定义了几个按钮，用于测试

<LinearLayout xmlns:android=“http://schemas.android.com/apk/res/android”

xmlns:tools=“http://schemas.android.com/tools”

android:id="@+id/LinearLayout1"

android:layout_width=“match_parent”

android:layout_height=“match_parent”

android:orientation=“vertical”

tools:context="$relativePackage.${activityClass}" >

<Button

android:id="@+id/button1"

android:layout_width=“match_parent”

android:layout_height=“wrap_content”

android:text=“创建数据库” />

<Button

android:id="@+id/button2"

android:layout_width=“match_parent”

android:layout_height=“wrap_content”

android:text=“添加数据” />

<Button

android:id="@+id/button3"

android:layout_width=“match_parent”

android:layout_height=“wrap_content”

android:text=“删除” />

<Button

android:id="@+id/button4"

android:layout_width=“match_parent”

android:layout_height=“wrap_content”

android:text=“修改” />

<Button

android:id="@+id/button5"

android:layout_width=“match_parent”

android:layout_height=“wrap_content”

android:text=“查找” />

TbUser.java定义的实体类，要继承DataSupport

package com.mcy.litepaldemo.model;

import java.util.Date;

import org.litepal.crud.DataSupport;

public class TbUser extends DataSupport {

private Integer id;

private String username;

private String password;

private String name;

private String sex;

private Date born;

public Integer getId() {

return id;

}

public void setId(Integer id) {

this.id = id;

}

public String getUsername() {

return username;

}

public void setUsername(String username) {

this.username = username;

}

public String getPassword() {

return password;

}

public void setPassword(String password) {

this.password = password;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public String getSex() {

return sex;

}

public void setSex(String sex) {

this.sex = sex;

}

public Date getBorn() {

return born;

}

public void setBorn(Date born) {

this.born = born;

}

public TbUser(String username, String password, String name, String sex,

Date born) {

super();

this.username = username;

this.password = password;

this.name = name;

this.sex = sex;

this.born = born;

}

public TbUser(Integer id, String username, String password, String name,

String sex, Date born) {

super();

this.id = id;

this.username = username;

this.password = password;

this.name = name;

this.sex = sex;

this.born
