【图片选择】Android 仿微信图片选择器疾风加载（单选，多选，相机）--唯剑做伴且随疾风前行

本文主要是介绍【图片选择】Android 仿微信图片选择器疾风加载（单选，多选，相机）--唯剑做伴且随疾风前行，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

请下载必要的配置文件按里面的目录copy导入使用

效果图

这里写图片描述

配置

app graild加依赖：compile 'com.squareup.picasso:picasso:2.4.0'
权限：

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

声明Activity

<activity
            android:configChanges="orientation|screenSize"android:name=".mvp.main.act.gongneng.imgselected.MultiImageSelectorActivity" />

修改布局文件：mis_list_item_camera 中的SquareFrameLayout改为自己目录下的，mis_list_item_image里面的自定义view都改为自己的
导入上面下载的文件改变导入类的包名就可以了ok

使用步骤

代码是最好的老师
