android - change the return key -

-

i want change name of enter button (the button circled in image ) search

enter image description here

so used 

  <edittext                 android:imeoptions="actionsearch"                 android:imeactionlabel="search"                   android:id="@+id/et_patientid"                  android:layout_width="400dip"                 android:layout_height="50dip"                 android:layout_torightof="@id/tv_patientid"                 android:background="@android:drawable/editbox_background" />

but didn't work

add android:imeoptions="actionsearch" , android:inputtype="text" edittext view

also add editor action listener

edittext.setoneditoractionlistener(new textview.oneditoractionlistener() {     @override     public boolean oneditoraction(textview v, int actionid, keyevent event) {         if (actionid == editorinfo.ime_action_search) {             performsearch();             return true;         }         return false;     } });  <edittext              android:id="@+id/et_patientid"             android:inputtype="text"             android:layout_width="400dip"             android:layout_height="50dip"             android:layout_torightof="@id/tv_patientid"             android:background="@android:drawable/editbox_background"             android:imeoptions="actionsearch"              android:imeactionlabel="search"  />

c# - Copy ObservableCollection to another ObservableCollection -

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

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...
