数据库框架--Litepal 使用笔记

Litepal的相关配置，其步骤如下：
1，在app/build.gradle文件中引入
compile ‘org.litepal.android:core:1.5.1’

2，配置litepal.xml文件，在app/main/创建assets目录，配置文件放在这个目录中。

<?xml version="1.0" encoding="utf-8"?>
<litepal>
    <dbname value="BookStore"/>
    <version value = "1"/>
    <list>
        <mapping class = "com.ming.bean.Book"/>
    </list>
</litepal>

3，在application中配置

 <application
        android:name="org.litepal.LitePalApplication"
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">

    </application>

4，创建javabean

public class Book extends DataSupport {
    private int id;
    private String author;
    private double price;
    private String name;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getAuthor() {
        return author;
    }

    public void setAuthor(String author) {
        this.author = author;
    }

    public double getPrice() {
        return price;
    }

    public void setPrice(double price) {
        this.price = price;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    @Override
    public String toString() {
        return "Book{" +
                "id=" + id +
                ", author='" + author + '\'' +
                ", price=" + price +
                ", name='" + name + '\'' +
                '}';
    }
}

5，litepal的一些简单操作方法
getDataBase();
save();
