Android Fragment what container is it in onCreateView() method -


i wonder container parameter in oncreateview(), cause when inflate view container make me wonder viewgroup this,is viewgroup activity add fragment ? if true why need attach in inflate method cause think add fragment viewgroup of activity in activity's xml anyway.

public view oncreateview(layoutinflater inflater, @nullable viewgroup container, bundle savedinstancestate) {      view view = inflater.inflate(r.layout.fragment_top,container,true);     return view; }

the inflate() method takes 3 arguments:

  • the resource id of layout want inflate.

  • the viewgroup parent of inflated layout. passing container important in order system apply layout parameters root view of inflated layout, specified parent view in it's going.

  • a boolean indicating whether inflated layout should attached viewgroup (the second parameter) during inflation.

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.
