Retrofit网络框架

1、定义接口

public interface JieKou {
    @GET("toutiao/index?type=top&key=097060266650f67b2cebd2a06aded587")
    Call<MyBean> getdata();

    @GET("toutiao/index")
    Call<MyBean> getdata(@Query("type")String name,@Query("key")String age);

    @GET("toutiao/index")
    Call<MyBean> getdata(@QueryMap Map<String ,String> map);

    @FormUrlEncoded
    @POST("toutiao/index")
    Call<MyBean> postData(@Field("type")String name,@Field("key")String age);

    @FormUrlEncoded
    @POST("toutiao/index")
    Call<MyBean> postData(@FieldMap Map<String ,String> map);
}

2、建实体MyBean

串放进实体Bean

3、XML：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    android:orientation="vertical" xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.mmaster.myapplication.MainActivity">

    <Button
        android:id="@+id/but"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="GET" />

    <Button
        android:id="@+id/but2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="GET2" />

    <Button
        android:id="@+id/but3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="GET3" />

    <Button
        android:id="@+id/post1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Post1" />

    <Button
        android:id="@+id/post2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Post2" />

</LinearLayout>

4、MainActivity页面 3GET  2Post请求

                myBeanCall.enqueue(this);
                break;
        }
    }

    @Override
