这是一个完整的图像选择代码，使用带有改造库的rest客户端裁剪和上传到服务器这里很少使用变量，因为我的使用请忽略它们
我也在gradel中使用这些库
compile 'com.squareup.retrofit2:retrofit:2.3.0'
compile 'com.theartofdev.edmodo:android-image-cropper:2.4.+'
compile 'com.squareup.retrofit:retrofit:1.6.1'
在 Mainfrest 中，我将其指定为 <activity
android:name="com.theartofdev.edmodo.cropper.CropImageActivity"
android:screenOrientation="portrait" />
