Initialize views of activity in android -


is necessary initialize views of activity in oncreate() only. can tell me best initializations of views of activity.

thanks

  1. no need initialize view if not modify it.
  2. you can initialize in activity lifecycle wish(before accessing).
  3. but is said best practice initialize in oncreate().

why:

  1. if see lifecycle oncreate called when app page not shown. onstart called when app partially visible & onresume called when visible. so, want ready before seeing it. 1 reason.

  2. another findviewbyid bit more expensive. so, don't want see when app visible.

  3. onstart & onresume may call multiple time when go page. so, it's preferable initialize once , multiple time.

so, choice yours now.

iOS: Performance of reloading UIImage(name:...) -

i have tableview , each row has icon. 90% of rows have same icon. in cellforrowatindexpath method load image assets folder this: var cellimage = uiimage(named: "myimage") does pose performance problem? os somehow smart enough it's same image each time? better if loaded image once , saved in class variable , assigned each time? uiimage 's named: api does kind of caching. if @ uiimage's documentation , states: use init(named:in:compatiblewith:) method (or init(named:) method) create image image asset or image file located in app’s main bundle (or other known bundle). because these methods cache image data automatically, recommended images use frequently.
