android - disabled listitems in alertdialog does not show up as grayed out items -

-

this scenario.

i have activity in have show dialog box (which listview wit 2 options optiona , optionb). listview used in single choice mode. option disabled(the user not allowed select option a)

these code fragments

private void createdialog() {     boolean disableoptiona = false;     ...     alertdialog.builder builder = new alertdialog.builder(this);     builder.settitle(getstring(r.string.codec_title));      listview modelist = new listview(this);     final arrayadapter<charsequence> modeadapter = custommenuadapter.createfromresource(this, r.array.codec_decoder,             android.r.layout.simple_list_item_single_choice, disableoptiona);     modelist.setchoicemode(listview.choice_mode_single);     modelist.setadapter(modeadapter);     builder.setview(modelist);     final dialog dialog = builder.create(); ... }

the codec_decoder array contains 2 options optiona , optionb. code custommenuadapter follows.

public class custommenuadapter extends arrayadapter<charsequence> {      boolean disableoptiona = true;      private custommenuadapter(context context, int textviewresid, charsequence[] strings, boolean disableoptiona) {         super(context, textviewresid, strings);         this.disableoptiona = disableoptiona;     }      public static custommenuadapter createfromresource(context context, int textarrayresid, int textviewresid,             boolean disableoptiona) {          resources resources = context.getresources();         charsequence[] strings = resources.gettextarray(textarrayresid);          return new custommenuadapter(context, textviewresid, strings, disableoptiona);     }      @override     public view getview(int position, view convertview, viewgroup parent) {         view view = super.getview(position, convertview, parent);         view.setenabled(isenabled(position));         return view;     }      @override     public boolean areallitemsenabled() {         return false;     }      @override     public boolean isenabled(int position) {         if (position == 0) {             if (disableoptiona) {                 return false;             }         }         return true;     } }

now works well, when optiona disabled, acts disabled looks enabled, not grayed out. ideas?

all need replace following code:

    @override     public boolean isenabled(int position) {     if (position == 0) {         if (disableoptiona) {             return false;         }      }     return true;    }

with in case want disable item on position 1:

     @override      public boolean isenabled(int position) {      if (position == 1)         return true;      return false;    }

c++ - Using OpenSSL in a multi-threaded application -

-
i have been writing soap client application in c++ on ubuntu using openssl https transport , pthreads threading. have number of threads - 1 central data acquisition thread periodically gets worker threads make soap requests via shared mutex protected queues. reading documentation openssl found is openssl thread-safe? in openssl faq describes mechanisms required ensure thread safety when using openssl. implemented , works fine. the reason question conceptual difficulty really. thinking implementing same functionality application has already, instead of using threads, create 2 seperate applications : 1 worker thread (of multiple copies running) , main data acquisition thread. use tcp sockets communicate between 2 rather mutex protected queues. may bad idea not important - confusing me would have implement same functions required ensure openssl thread safety in second approach or not? my guess not have , treated independent (indeed surely must many applications use openssl) re...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
