i have db integration test i'm running using boost build. test needs commandline args (db username, password). what's best way set via boost build in way that's configurable user (via environment variables, bjam commandline, user-config.jam)? i know can variables: import os ; local db_pass = [ os.environ db_pass ] ; run dbtest : test.cpp : --dbpass $(db_pass) ; this can set via commandline ( bjam -s db_pass=pass ) or via environment variable. on other hand, boost build tends of configuration via feature mechanism. define new feature , configuration data right place way. what's pros , cons of each approach? 1 should take? if features: how that? nb: actual test within jamfile that's used jamroot, not directly in root file. i use suggestion of variables. provide great deal of flexibility. don't see how "feature" in case things.

i developping app has page there must header followed multiple recycler views within viewpager. however, not know how "hide" header when scrolling down. the following layout not work : - recyclerview - header - slidingtablayout - viewpager - recyclerview because verticaly scrollable view cannot put inside verticaly scollable view. possible create type of layout in way because twitter did : so how 1 achieve create type of layout? theorical solution suggestion if had layout : - linearlayout - header - slidingtablayout - viewpager - recyclerview and when recyclerview scrolled, move manually every element upwards header progressively "hidden" , viewpager higher, work? because verticaly scrollable view cannot put inside verticaly scollable view that not true, can put scrollable view scrollable view. hard manage scrolling events , of times not necesseary. should not nest scrollable views. howe
