安卓Base64批量上传至服务器

Step1：效果图
Step2:整体过程
/**
* 由于请求框架开始就是Xutils compile ‘org.xutils:xutils:3.3.36’ 不做更改
* 1.第三方的图片选择器（支持选择多张图片、预览、删除等）
* 2.onActivityResult 返回选择图片的数组
* 3.注意：接口有2个 A接口：专门用于接受图片base64码 B接口用来上传 标题、内容和拼接的url链接
* 4.
* ①：将选取的图片路径的转化为base64字符串 encode()方法
* ②：选取多张时采用计数叠加一张张的上传 每上传一张将地址进行拼接 StringBuffer()方法
* ③：当上传图片完成时A接口结束，在调用B接口 传入对应的参数即可，图片是多张之后的url链接，要去除第一个,号否则后台解析失败 substring()方法
*/
上图中一共上传了9张图片，蓝色部分就是一至9张的叠加链接，一共花了9秒 当然这些图片都是很小的，如果是高清图 记着一定要压缩 否则会非常慢，因为流程非常多，容易卡死
Step3:进入主题
build.gradle 引入这些
//recyclerview 展示图片的 compile 'com.android.support:recyclerview-v7:25.3.1' //请求网络框架xutils compile 'org.xutils:xutils:3.3.36' //加载图片的glide compile 'com.github.bumptech.glide:glide:3.7.0' //图库选择器 compile 'me.iwf.photopicker:PhotoPicker:0.9.5@aar' //压缩图片的 compile 'com.zxy.android:tiny:0.0.6' //删除图片显示的snackbar compile 'com.android.support:design:26.0.0-alpha1Step4：AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?><manifest package="com.helloworld.base64demo" xmlns:android="http://schemas.android.com/apk/res/android"> <uses-permission android:name="android.permission.INTERNET" /> <application android:name=".AppContext" android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:roundIcon="@mipmap/ic_launcher_round" android:supportsRtl="true" android:theme="@style/AppTheme"> <activity android:name=".MainActivity"> <intent-filter> <action android:name="android.intent.action.MAIN"/> <category android:name="android.intent.category.LAUNCHER"/> </intent-filter> </activity> <!-- photopicker图片选取界面 --> <activity android:name="me.iwf.photopicker.PhotoPickerActivity" android:theme="@style/Theme.AppCompat.NoActionBar" /> <!-- photopicker选取图片预览删除界面 --> <activity android:name="me.iwf.photopicker.PhotoPagerActivity" android:theme="@style/Theme.AppCompat.NoActionBar" /> </application></manifest>Step5：4个java类
1.AppContext
2.MainActivity
3.PhotoAdapter
4.RecyclerItemClickListener
