java - Non Deprecated findPreference() Method? - Android -

-

i want detect when preference contained in listview gets clicked, can launch intent manage selection.

i have done in layout xml file:

<preference android:title="about" android:key="mykey"></preference>

and following in java code:

preference mypref = (preference) findpreference("mykey"); mypref.setonpreferenceclicklistener(new onpreferenceclicklistener() {              public boolean onpreferenceclick(preference preference) {                  //open browser or intent here              }          });

but method public preference findpreference (charsequence key) deprecated.

  1. is there non deprecated equivalent?
  2. if not, if use anyway?
  3. how can fragments me task in better way?chek here: preferences without deprecated methods.

here can check xml layout structure activity has, , snapshot of application:

xml:

<?xml version="1.0" encoding="utf-8"?> <preferencescreen xmlns:android="http://schemas.android.com/apk/res/android" >      <preference          android:key="about"          android:title="@string/titleabout"          android:summary="@string/summaryabout"      />      <preference          android:key="labeltaxonomy"          android:title="@string/titlelabeltaxonomy"          android:summary="@string/summarylabeltaxonomy"      />  </preferencescreen>

snapshot:

snapshopt

after clicking on (or access label taxonomy) preference, i'd open intent of kind (could video or else...the names misleading).

is there non deprecated equivalent?

if using preferencefragment on api level 11+ devices, call findpreference() on it. otherwise, call findpreference() on preferenceactivity, have no choice.

if not, if use anyway?

it work.

how can fragments me task in better way?

api level 11+ introduced preferencefragment way of constructing contents of preferenceactivity. welcome use them, if still supporting older devices, cannot use preferencefragment devices.

that being said:

i want detect when preference contained in listview gets clicked, can launch intent manage selection.

you not need java code this. use:

    <preferencescreen             android:title="@string/title_intent_preference"             android:summary="@string/summary_intent_preference">          <intent android:action="android.intent.action.view"                 android:data="http://www.android.com" />      </preferencescreen>

(as seen in javadocs preferenceactivity)

this create entry in preference ui that, when clicked, start activity specified intent.

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...
