java - Text box value not updating properly according to the change in spinner value (and i have tried most of the methods in stackoverflow) -


there spinner in mainactivity , 1 text box in fragment. task change value of text box according selected spinner value. code works well, textbox changes state after 2 swipes. don't know why lagging happening. me out (before downvoting kindly solutions)

here code in main activity

spinner = (spinner)findviewbyid(r.id.spinner2); final arrayadapter<string> dataadapter1 = new arrayadapter<>(this,android.r.layout.simple_spinner_item,array2); dataadapter.setdropdownviewresource(android.r.layout.simple_spinner_dropdown_item); spinner.setadapter(dataadapter1); spinner.invalidate();  spinner.setonitemselectedlistener(new adapterview.onitemselectedlistener() {     @override     public void onitemselected(adapterview<?> parent, view view, int position, long id) {         //dataadapter1.notifydatasetchanged();         toast.maketext(getapplicationcontext(),"well",toast.length_long).show();         string pos = (string) spinner.getselecteditem();         sharedpreferences sharedpref = getsharedpreferences("mode", activity.mode_private);         sharedpreferences.editor prefeditor = sharedpref.edit();         prefeditor.putstring("userchoicemode", pos);         prefeditor.commit();     }     @override     public void onnothingselected(adapterview<?> parent) {     } });

my fragment code :

final textview modeselect = (textview) view.findviewbyid(r.id.pass);  final sharedpreferences sharedpref = this.getactivity().getsharedpreferences("mode", activity.mode_private); string = sharedpref.getstring("userchoicemode",selected);  modeselect.settext("" + get);

in fragment

 @override public void setuservisiblehint(boolean isvisibletouser) {     try {         if (isvisibletouser) {             final textview modeselect = (textview) view.findviewbyid(r.id.pass);  final sharedpreferences sharedpref = this.getactivity().getsharedpreferences("mode", activity.mode_private); string = sharedpref.getstring("userchoicemode",selected);  modeselect.settext("" + get);         }     } catch (exception e) {         e.printstacktrace();     }     super.setuservisiblehint(isvisibletouser); }

just add override method fragment , put value of selected spinner item in text view of fragment in method. inflated view should declared globally

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
