In the package org.mapsforge.samples.android there is the class PoiSearchViewer,

which has the variable private static final String POI_CATEGORY = "Restaurants";

How can I get all possible domain values ("Restaurants", "Cinemas",...) out of a POI-file?

I have a POI-file from openandromaps.org which has quite a bit long domain values e.g. "Drinking water / Trinkwasser".

How do I have to adjust the class PoiSearchViewer, that I can only search with e.g. "Trinkwasser"?

Thank you!

You can use the PoiCategoryManager.getRootCategory().deepChildren() to retrieve all categories.

The poi categories are configured by the poi file creators.

You can search by name / tags, see the documentation about filtered search.
(this API is demonstrated in VTM repository)
