java - Android Reusing activities with different data -


hi i'm developing android application , have 2 activities practically same, load different data. have 2 activities lot of duplicate code , feel can optimise using 1 activity.

activity 1:

    @override public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);      setcontentview(r.layout.right_hearing_test);      string tophtml = this.getstring(r.string.top_content);     string bottomhtml = this.getstring(r.string.bottom_content);      view infobutton = findviewbyid(r.id.info_button);     infobutton.setvisibility(view.visible);      textview titletext = (textview) findviewbyid(r.id.title_text);     titletext.settext(r.string.hearing_test);      mscrollbutton = (scrollview) findviewbyid(r.id.scroll_view);      topcontent = (webview) findviewbyid(r.id.top_content);     topcontent.setbackgroundcolor(0);      bottomcontent = (webview) findviewbyid(r.id.bottom_content);     bottomcontent.setbackgroundcolor(0);      activityhelper = new activityhelper(this);      topcontent.loadurl("file:///android_asset/html/" + tophtml);     bottomcontent.loadurl("file:///android_asset/html/" + bottomhtml);      getscreensize();     getmargins();      setresult(result_ok); }

activity 2

    @override public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);      setcontentview(r.layout.left_hearing_test);      view infobutton = findviewbyid(r.id.info_button);     infobutton.setvisibility(view.visible);      mscrollbutton = (scrollview) findviewbyid(r.id.scroll_view);      topcontent = (webview) findviewbyid(r.id.top_content);     topcontent.setbackgroundcolor(0);      bottomcontent = (webview) findviewbyid(r.id.bottom_content);     bottomcontent.setbackgroundcolor(0);      string tophtml = this.getstring(r.string.switch_file);     string bottomhtml = this.getstring(r.string.bottom_content);      activityhelper = new activityhelper(this);      topcontent.loadurl("file:///android_asset/html/" + tophtml);     bottomcontent.loadurl("file:///android_asset/html/" + bottomhtml);      getscreensize();     getmargins(); }

i load data web views , button in activity 1, user test, take user activity 2. here display different data in web views , button.

my question if reuse 1 activity both pages, how load correct data each 1 , possible?

i've used helper class lot of other methods use on both activities passing context in, use 1 activity different content display in webviews , button!

thanks input!

simply keep flag decide option chose.. bellow give idea how control it.

you can control flag unisg getstringextra(), putstringextra() example. start activity fromactivity class.

fromactivity.java

.......     intent = new intent(fromactivity.this,youractivity.class); i.putextra("flag","optionone"); startactivity(i); .......

or 

.. intent = new intent(fromactivity.this,youractivity.class); i.putextra("flag","optiontwo"); startactivity(i); ...

youractivity.java

        @override         public void oncreate(bundle savedinstancestate) {          ......         ..         ..         string flag = string.valueof(getintent().getstringextra("flag"));          if(flag.equalsignorecase("optionone")){              string tophtml = this.getstring(r.string.top_content);             string bottomhtml = this.getstring(r.string.bottom_content);              textview titletext = (textview) findviewbyid(r.id.title_text);             titletext.settext(r.string.hearing_test);           }else if(flag.equalsignorecase("optiontwo")){             string tophtml = this.getstring(r.string.top_content);             string bottomhtml = this.getstring(r.string.bottom_content);         }else{     }         .....         ...         ...         if(flag.equalsignorecase("optionone")){             setresult(result_ok);         }         .... }

opencv - DataType<cv::detail::deriv_type>::depth what is it used for -

i wondering why line used in lucas kanade tracker in opencv: datatype<cv::detail::deriv_type>::depth can explain me? in opencv, depth of mat refers type of data contained in mat 's data buffer. represented integer values correspond given data type. these integers commonly abstracted appropriate macro definition (e.g. uchar data represented macro cv_8u ). cv::datatype type-traits class provides method obtain corresponding integer value without having memorize macro means data type. there few cases user code needs use datatype::depth . more common datatype::type . a simple example shows 1 possible use of datatype::depth : cv::mat uchar_data = cv::mat::ones(3, 3, cv_8uc1); cv::mat float_data; uchar_data.convertto(float_data, cv::datatype<float>::depth); // ^^ equivalently replaced // cv_32f macro float_data.at<float>(0,1) += 0.5f; std::cout << float_data << std::endl;...

python 3.x - Mapping specific letters onto a list of words -

can please suggest approach write piece of codes automatically maps letter in letter_str onto dic_key (a dict key string type contains dashes match length of words in word_lst)? so, mapping occurs if letter appears in every words in list @ same position no matter how many words in list. if no letter appears @ position words in word list new_dic_key '----'. please see examples below thanks word_lst = ['ague', 'bute', 'byre', 'came', 'case', 'doze'] dic_key = '----' letters_str ='abcdefghijklmnopqrstuvwxyz' new_dic_key = '---e' if word_list = ['bute', 'byre'] new_dic_key = 'b--e' or word_list = ['drek', 'drew', 'dyes'] new_dic_key = 'd-e-' if words in word_list of same length code give want: word_list = ['drek', 'drew', 'dyes'] cols = [] in range(len(word_list[0])): cols.append([]) word in ...
