android - Displaying a TextView immediately after another -


i first time developer android, can i've been learning developing. of code doesn't have xml layout, had no problem patching rookie mistakes. said, rookie mistakes has caught me in regards 2 textviews when designed them gui interface designer (my major rookie mistake).

my display_city tv , display_today_date tv seem have symbiotic relationship each other. removal of either 1 crash app. seem dependent on each other changing each other's positioning impossible (at least myriad of things have tried such setting layout margins).

<textview     android:id="@+id/display_city"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:layout_margintop="20dip"     android:layout_above="@+id/display_today_date"     android:layout_below="@+id/get_data"     android:layout_centerhorizontal="true"     android:gravity="center_horizontal" />  <textview     android:id="@+id/display_today_date"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:layout_centerhorizontal="true"     android:layout_below="@+id/display_pollen_type"/>

my question - how position display_today_date after display_city? when first started android app, relied lot on gui builder. first rookie mistake, resulted in symbiotic relationship explained.

currently app looks like:

enter image description here

i have tried changing display_today_date's layout android:layout_below="@+id/display_city. results in crash. checked logcat, did not give me relevant information reason of crash within xml file.

p.s. get_data textedit box.

you have city show above date line android:layout_above="@+id/display_today_date". can't have 2 views in relative layout each reference other, or won't able figure out do. if don't want put city above date, delete line add code place want.

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
