java - constructor cannot resolve Array adapter in android -


i don't know error did. shows me can not resolve constructor arrayadapter on array adapter code.help me fix out.( have used getactivity() because have written code on fragment section) , gets crashes after it.i have tried issue fixing methods in stack overflow .(before down voting suggest me solutions )

spinner = (spinner) view.findviewbyid(r.id.spinner3); arrayadapter<string> dataadapter = new arrayadapter<string>(this,getactivity(),android.r.layout.simple_spinner_item,def); dataadapter.setdropdownviewresource(android.r.layout.simple_spinner_dropdown_item); spinner.setadapter(dataadapter);

here error log

try this, if use fragment:

1. code designed fetch static array

    arrayadapter myadapter = arrayadapter.createfromresource(             getactivity(), r.array.my_array, android.r.layout.simple_spinner_item);      myadapter.setdropdownviewresource(android.r.layout.simple_spinner_dropdown_item);     myspinner.setadapter(myadapter);

2. if fetching dynamic array, below sample code work.

in sample, i've fetched list db. can change upon requirement.

    spinner maritalspinner = (spinner) view.findviewbyid(r.id.marital_spinner);     list<maritalstatus> maritalstatuslist = new arraylist<>();     list<string> maritalstatusarray = new arraylist<>();     maritalstatuslist = dbconnection.getmaritalstatus(maritalstatusdao);     maritalstatusarray.clear();     maritalidarray.clear();     maritalstatusarray.add("~select~");     maritalidarray.add(0l); // number '0' , alphabet 'l'(small 'l') not number '1'     (maritalstatus marital : maritalstatuslist) {         string maritalstatus = marital.getmaritalstat();         long maritalid = marital.getmaritalid();         maritalstatusarray.add(maritalstatus);         maritalidarray.add(maritalid);     }     maritaladapter = new arrayadapter<>(getactivity(), android.r.layout.simple_spinner_item, maritalstatusarray);     maritaladapter.setdropdownviewresource(android.r.layout.simple_spinner_dropdown_item);     maritaladapter.notifydatasetchanged();     maritalspinner.setadapter(maritaladapter);

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
