okHttp之get post请求 调用相机

一.首先导入依赖

//    ok
    compile 'com.squareup.okhttp3:okhttp:3.9.0'
    //制作头像 圆形imageview
    compile 'de.hdodenhof:circleimageview:2.2.0'

二.联网权限
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
    <!--允许写入sdcard的权限-->
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>

三.控件里面写入第三方的布局

<de.hdodenhof.circleimageview.CircleImageView
        android:id="@+id/head_icon"
        android:layout_width="50dp"
        android:layout_height="50dp"
        android:src="@mipmap/ic_launcher" />

四.写主方法

package com.example.gjl.day02_okhttp;

import android.content.Intent;
import android.net.Uri;
import android.os.Environment;
import android.provider.MediaStore;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;

import java.io.File;
import java.io.IOException;

import de.hdodenhof.circleimageview.CircleImageView;
import okhttp3.Call;
import okhttp3.Callback;
import okhttp3.FormBody;
import okhttp3.MediaType;
import okhttp3.MultipartBody;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.RequestBody;
import okhttp3.Response;
