 本人小白，那个大神看到有问题可指出，谢谢。。。。

这个是接着之前的 android+myeclipse+mysql下拉框数据绑定 的服务器（后台）来做的，所以这里就只给 Android的代码，如果想要服务器的代码去 android+myeclipse+mysql下拉框数据绑定找就好了

一：Android studio

•  1);先进行准备前工作先 在build.gradle四个地方要加入代码

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
        mavenCentral()//apllay   // add plugin
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'
        classpath 'org.greenrobot:greendao-gradle-plugin:3.2.2' // add plugin
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

// 这个非常重要，会生成Dao的类
greendao {    //add plugin
    schemaVersion 2
    //生成greedao的对象类的路径   

设置DaoMaster,DaoSession,Dao包的路径，我不太喜欢它原来的路径，每次找都很麻烦，所以把它放在一个自己方便看的路径下来，你也可以不要下面这两句!
    daoPackage 'zhu.com.sprnner_cbo.greendao'
    targetGenDir 'src/main/java'//保存到java代码路径   ==》这句你可以不要
}

       

如果没有这俩句，那么DaoMaster,DaoSession,Dao的原路径是在这里的

有这俩句，那么DaoMaster,DaoSession,Dao那么路径挺好找的

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:26.+'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    testCompile 'junit:junit:4.12'
    compile 'com.loopj.android:android-async-http:1.4.9'// add library==》这个是添加 网络请求的插件
    compile 'org.greenrobot:greendao:3.2.2' // add library  ==>这个是 添加 greedao插件
}

 a):因为需要网络的请求 所以 要必须 要在AndroidManifest.xml加一句代码，不加就会出现下面这种错误的情况

 好了配置弄好剩下的就 很好解决了

b):设置实体类： 

  实体类 要根据返回的json中 相对于的key 一一对应

 

 注意：   主键：id必须要设置Long的类型 ，切记 必须要加入  @Entity， 和@Id

 

   设置好变量后 ，还有一个操作 设置 生成DaoMaster,DaoSession,Dao类的操作，这它就会自动补全我们实体类剩下的get和set的方法了

 ================生成的========》

  

    最后在实体类中再加 一个方法 得到 从 服务器专递的json的数据
    // 将json ==>转化为 Bean的对象（即Tb_Cbo_CLDL的对象）
    public static  Tbmep json_To_Bean(JSONObject object){
        try {
            return  new Tbmep(object.getLong("did"),
                    object.getString("dname")
            );
        }catch (Exception e){   }
        return  null;
    }

 需要用到 一些应用来设置界面 

  a):values的设置

 b)drawable的设置

btn_click_radius_press.xml

    <item android:drawable="@drawable/btn_radius"/>
</selector>

    <!--要是button可以变色：
    那么要把在btn_radius.xml的btn_bg和btn_press.xml没按的效果组合起来就可以进行变色的效果-->

 btn_press.xml

    <stroke android:width="1dp"
        android:color="#A3AAAA">

    <corners android:radius="5dp"/>
</shape>

    <!--这个是按的效果： 这个是定义进度条的时候使用 button 变色的情况-->
