I'm writing a small corporate program that sends photos to the company's server.

Each photo should fall into a specially allocated folder, for example photo of the forest should be in the folder nature -> forest. The directory tree I'm getting from the server as a list of objects with fields:

name
id
parentId
prefix

Where prefix is a numeric value, for example:

Nature - 1000;
- Forest - 1100
- Hill - 1200
Animals - 2000
- Bear - 2100
- Mouse - 2200
- and so on.

In order to send a photo user needs to select the appropriate folder. The question is, how to implement easy and clear folder-picker?

At the moment, the picker is made using AutoCompleteTextView, but in order to enter the first three letters of the folder name - this name should be remembered to the user and if the folders are around 10, then it will not be difficult, but if the folders become more than 100 - then hold all the names in the head become simply impossible.

Maybe someone have an idea how to implement the user interface to select a folder, without forcing employees to learn a hundred names?

Put all in a ListView. Or yet better ExpandableListView. – greenapps Aug 22 '17 at 12:09

You can do it many way.... I think you can keep the directory information in sqlite and use as folder picker. – Aug 22 '17 at 12:09

@greenapps, as i know ExpandableListView can have only 3 levels, in my case it's not enough – Vsevolod Vladimirovich Aug 23 '17 at 17:52
???? You need only two levels you said. – greenapps Aug 23 '17 at 18:35
@greenapps, you're right. Perhaps I gave an unfortunate example. – Vsevolod Vladimirovich Aug 27 '17 at 12:36
