关于android:智汀云盘开发指南android端文件夹共享

1. 阐明

文件夹共享分为两种状况：

• 一种是在创立文件夹时抉择文件夹类型为共享文件夹，另外他人共享给我的文件夹。
• 第一种状况是没有共享者的，根目录不能共享，相当于能够有多个拜访成员的非共享文件夹；

第二种状况是有共享者的，在共享文件列表能够再共享给他人。

以第一种形式共享文件夹时，能够给访问者设置读、写和删权限；

以第二种形式共享文件夹，读、写和删的权限受制于共享者本人是否有对应的权限。

在设置权限时，如果用户去掉了读权限，那么写和删权限也会随之去掉；如果用户抉择了写或删权限，那么会主动把读权限也选上。

1) 次要代码实现

public class ShareFolderActivity extends BaseMVPDBActivity<ActivityShareFolderBinding, ShareFolderContract.View, ShareFolderPresenter> implements ShareFolderContract.View {
    ...

            public void onConfirm(int read, int write, int del) {List<String> paths = new ArrayList<>();
                for (FileBean fileBean : folders){ // 要共享的文件夹
                    paths.add(fileBean.getPath());  
                }
                List<Integer> to_users = new ArrayList<>();
