DBFlow for eclipse 移植

根据DBflow3.0移植过来的，移植过程中有很多问题，比如类找不到啊，因为代码比较多修改起来比较慢，而且移植到eclipse上面提前编译直接报错，还找不到错误的原因，没办法只有一步一步的通过文件打log的方式才找到原因，我修改的地方我都写在com.gengsheng 包下面了Util.java

我还增加了可以支持数据库放入到SD卡中

还可以用sqlite3工具类创建好数据库然后把数据库放入到res/raw/initdb.db，注意把名字修改成initdb.db文件

DBFlow3 好处在于效率比反射的高

使用方式和github 上面的一样

1 初始化

 File docFilePath = CreatFileUtil.getDownLoad(this);

//初始化
//把数据库放入的地址，传null放在默认位置 ，true代表是用res/raw下面的数据库，必须要保证数据库还没创建成文件，也就是1

FlowManager.init(this, docFilePath, true);

2    创建表对象 //注意属性是public  修饰

<pre name="code" class="java"><pre name="code" class="java">package com.jtv.testdatabase.db;


import java.util.List;


import com.raizlabs.android.dbflow.annotation.Column;
import com.raizlabs.android.dbflow.annotation.ModelContainer;
import com.raizlabs.android.dbflow.annotation.PrimaryKey;
import com.raizlabs.android.dbflow.annotation.Table;
import com.raizlabs.android.dbflow.sql.language.SQLite;
import com.raizlabs.android.dbflow.structure.BaseModel;


/**
 * Created by gengsheng on 2016/3/14.
 */
@ModelContainer
@Table(database = StaticCheckDatabase.class)
public class Zx_lc extends BaseModel {
    @PrimaryKey(autoincrement = true)
    public long id;
    @Column
    public String wonum;
    @Column
    public String assetnum;
    @Column
    public double startlc;
    @Column
    public double endlc;
    
    @Column
    public String email;
    
    @Column
    public String email_hello;
    
    @Column
    public String ADD3;

}

3 创建数据库对象
@Database(name = StaticCheckDatabase.NAME, version = StaticCheckDatabase.VERSION)
public class StaticCheckDatabase {
    public static final String NAME= "staticcheck";
    public static final int VERSION=14;
}

//4 使用  zx_lc = new Zx_lc();
zx_lc.assetnum = "zz1234";
zx_lc.wonum = "wn3345";
zx_lc.startlc = 110.234;
zx_lc.endlc = 111.234;
zx_lc.insert();

//5  也支持sql语句直接写
// 执行原生sql
BaseDatabaseDefinition database = FlowManager.getDatabase(StaticCheckDatabase.NAME);
AndroidDatabase android = (AndroidDatabase) database.getWritableDatabase();
Cursor rawQuery = android.rawQuery("select * from zx_lc", null);
if (rawQuery != null) {
while (rawQuery.moveToNext()) {
String string = rawQuery.getString(0);
Toast.makeText(this, string, Toast.LENGTH_SHORT).show();
}
rawQuery.close();
}

//删除表
new Delete().from(Zx_lc.class).execute();
// 实时保存，马上保存
new SaveModelTransaction<>(ProcessModelInfo.withModels(Zx_lcList)).onExecute();

// 异步保存，使用异步，如果立刻查询可能无法查到结果
TransactionManager.getInstance().addTransaction(new SaveModelTransaction<>(ProcessModelInfo.withModels(Zx_lcList)));


6 表结构变化
如果新增表直接创建一个对象，创建对象参考第二步，并把版本增加
如果增加表列
/**
  * 在版本11中增加了email字段
 * 
 * @author 
 *
 */
@Migration(version = 11, database = StaticCheckDatabase.class)
public class AleartZx_lc extends AlterTableMigration<Zx_lc> {


public AleartZx_lc(Class<Zx_lc> table) {
super(table);
}


@Override
public void onPreMigrate() {
addColumn(SQLiteType.TEXT, Zx_lc_Table.email.getNameAlias().getName());
addColumn(SQLiteType.TEXT, Zx_lc_Table.email_hello.getNameAlias().getName());
// addColumn(SQLiteType.TEXT,
// Zx_lc_Table.ADD3.getNameAlias().getName());
}

},

//如果12版本有增加了，在创建一个这种的把版本改为12，并把数据库对象中版本改为12

7 引入jar包方式并提前编译  把dbflow3.0 放入lib下面，然后选中项目,鼠标右键properties,点击java compiler 在点annotation Processin 在点击Factory path ,把右边的ENABLE project sep...勾选上然后点击右侧的Add JARs..,选中DBflow3.0.jar ，然后apply ,然后ok 完毕

8 当你引用注解时编译器就会自动创建表所需要的对象

9 当你如果改了数据库对象值，文件最好重新编译下，（不重新编译很有可能项目直接运行奔溃）它会重新生成文件，你可以把自动生成的包删了，然后看见删了后，编译器会重新编译一个文件，

10 注解如果没有设置源代码存放位置，默认生成在项目下面，是一个隐藏文件，如果项目报错很有可能是switch的原因，需要jre为1.7才可以

完整的创建数据库和创建表代码，其他自动生成，使用方式参考上面

//1 创建数据库

import com.raizlabs.android.dbflow.annotation.Database;


@Database(name = ToolsDB.NAME, version = ToolsDB.Version)
public class ToolsDB {
	
	//数据库版本
	public final static int Version = 9;
	
	//数据库名字
	public final static String NAME = "tools";
}

//2 创建表

/**
 * 物料编号表
 * <p>
 *
 * @author 
 * @version 2016年3月26日
 */

@Table(database = ToolsDB.class)
