配置

依賴

在module的build.gradle中：

    implementation 'com.squareup.okhttp3:okhttp:3.14.7'implementation 'com.squareup.okio:okio:1.17.5'

AndroidManifest.xml

  <uses-permission android:name="android.permission.INTERNET" />

xml文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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"android:orientation="vertical"tools:context=".test.TestOKHttpActivity"><Buttonandroid:id="@+id/btn_get_post"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="get和post" /><TextViewandroid:id="@+id/tv_result"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="xx"android:textSize="15sp"/>
</LinearLayout>

總結

原生okhttp比較麻煩，使用第三方庫去封裝使用
