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
/**

paths.add(fileBean.getPath());
}
List<Integer> to_users = new ArrayList<>();
for (MemberBean.UsersBean usersBean : memberAdapter.getSelectedUsers()){ // 抉择的成员
to_users.add(usersBean.getUser_id());
}
ShareRequest shareRequest = new ShareRequest(to_users, paths, read, write, del, Constant.userName);
mPresenter.share(Constant.scope_token, shareRequest);
}
});
}
...
public class OnClickHandler {public void onClick(View view) {int viewId = view.getId();
if (viewId == R.id.ivBack){ // 返回
...
}else if (viewId == R.id.tvAll){ // 全选

bundle.putInt("read", 1); // 读权限

bundle.putBoolean("checkSaveEnabled", true);
List<PermissionUserBean> users = new ArrayList<>();

}
}
}
