the code provided in comment:

<radiogroup     xmlns:android="schemas.android.com/apk/res/android";      android:layout_width="fill_parent"      android:layout_height="wrap_content"     android:orientation="vertical">      <radiobutton          android:id="@+id/radio_blue"          android:layout_width="wrap_content"          android:layout_height="wrap_content"          android:text="@string/pirates"          android:onclick="onradiobuttonclicked"/>      <radiobutton          android:id="@+id/radio_red"          android:layout_width="wrap_content"          android:layout_height="wrap_content"          android:text="@string/ninjas"          android:onclick="onradiobuttonclicked"/>  </radiogroup>

in order handle onclick events, have use activity class handle action.

you can start:

public class mainactivity extends activity {     textview title;     radiobutton red_button, blue_button, ...;      protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.[your xml name]);           //getting widget references         title = (textview) findviewbyid(r.id.title);         red_button = (radiobutton) findviewbyid(r.id.radio_red);           //handle onclick events         red_button.setonclicklistener(new view.onclicklistener() {             @override             public void onclick(view v) {                 title.settextcolor(color.parsecolor("#ff0000"));             }         });     } }

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer
