android - Application with 2 Activities Running Parallel -


i have application uses 2 activities, when clicking item in listview inside activity 1 goes activity 2 , adds new fragment it, , pressing button goes activity 1, activity 2 , fragments/controls destroyed, , clicking item in activity 1, creates new activity 2 , adds fragment it.

is there anyway can run 2 activities in parallel? both running in parallel? use code start activity 2

intent intent = new intent(this, displaydataactivity.class); startactivity(intent);

can keep reference in activity 1 clicking on listview items shows activity 2 if it's created?

thanks

i don't know why need that. check app architecture and/or ui - possibly wrong.

but possible - need maintain 2 activity tasks (google documentation)

  • use different taskaffinity activities create 2 tasks (separate activity stacks)
  • override onback button if need - replace appropriate second activity intent call

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
