android - How to add tabs to listview? -


i need add 2 tabs in listing , not know how it, wanted add 1 in first row , after fourth item separates: trend , genre, saw adding new xml layout need because can not, text between items..

my main activity:

public class inicio extends appcompatactivity {      private listview listaitens;     private string[] itens = {             "home", "playlist", "trend", "conta", "live", "rock", "hip hop", "pop",             "house", "gospel music", "metal", "alt rock", "sport", "game"     };     integer[] imgid={             r.drawable.home,             r.drawable.playlist,             r.drawable.trend,             r.drawable.conta,             r.drawable.live,             r.drawable.rock,             r.drawable.hiphop,             r.drawable.pop,             r.drawable.house,             r.drawable.gospel,             r.drawable.metal,             r.drawable.alternative_rock,             r.drawable.sport,             r.drawable.game,     };      @override     public void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_inicio);          listaitens = (listview) findviewbyid(r.id.listview);          customlistadapter adapter=new customlistadapter(this, itens, imgid);         listaitens=(listview)findviewbyid(r.id.listview);         listaitens.setadapter(adapter);          listaitens.setonitemclicklistener(new adapterview.onitemclicklistener() {             @override             public void onitemclick(adapterview<?> adapterview, view view, int position, long id) {                  if (position == 0) {                     intent intent = new intent(inicio.this, insmainactivity.class);                     intent.putextra("link", "https://m.youtube.com/");                     startactivity(intent);

my adapter:

public class customlistadapter extends arrayadapter<string> {      private final activity context;     private final string[] itens;     private final integer[] imgid;      public customlistadapter(inicio context, string[] itens, integer[] imgid) {         super(context, r.layout.mylist, itens);          this.context=context;         this.itens=itens;         this.imgid=imgid;     }      public view getview(int position,view view,viewgroup parent) {         layoutinflater inflater=context.getlayoutinflater();         view rowview=inflater.inflate(r.layout.mylist, null,true);          textview txttitle = (textview) rowview.findviewbyid(r.id.item);         imageview imageview = (imageview) rowview.findviewbyid(r.id.icon);         textview extratxt = (textview) rowview.findviewbyid(r.id.textview1);          txttitle.settext(itens[position]);         imageview.setimageresource(imgid[position]);         extratxt.settext("access "+itens[position]);         return rowview;      }

xml listview

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:orientation="horizontal" >      <imageview         android:id="@+id/icon"         android:layout_width="60dp"         android:layout_height="60dp"         android:padding="5dp" />      <linearlayout android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:orientation="vertical">          <textview             android:id="@+id/item"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:text="medium text"             android:textappearance="?android:attr/textappearancemedium"             android:layout_marginleft="10dp"             android:layout_margintop="5dp"             android:padding="2dp"             android:textcolor="#000000" />         <textview             android:id="@+id/textview1"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:text="textview"             android:layout_marginleft="10dp"/>     </linearlayout> </linearlayout>

if can me, thank much.

you have create separate xml files:

  • one create row layout
  • another tab

and make changes adapter below

public class customlistadapter extends arrayadapter<string> {  private static final int type_item = 0; private static final int type_tab = 1;  private final activity context; private final string[] itens; private final integer[] imgid;  public customlistadapter(inicio context, string[] itens, integer[] imgid) {     super(context, r.layout.mylist, itens);      this.context=context;     this.itens=itens;     this.imgid=imgid; }  public view getview(int position,view view,viewgroup parent) {     int type = getitemviewtype(position);      layoutinflater inflater=context.getlayoutinflater();      if (view == null) {           // inflate layout according view type           layoutinflater inflater = (layoutinflater) ctx.getsystemservice(context.layout_inflater_service);     if (type == type_item) {          view = inflater.inflate(r.layout.your_item_layout, parent, false);     } else {          view = inflater.inflate(r.layout.your_tab_layout, parent, false);     }     textview txttitle = (textview) view.findviewbyid(r.id.item);     imageview imageview = (imageview) view.findviewbyid(r.id.icon);     textview extratxt = (textview) view.findviewbyid(r.id.textview1);      /**     * tab layout textview     */     if (type == type_tab) {       textview tab = (textview) view.findviewbyid(r.id.tab);       tab.settext("your text");     }      txttitle.settext(itens[position]);     imageview.setimageresource(imgid[position]);     extratxt.settext("access "+itens[position]);      return view;  }  /** * override function, returns number of types of views in list.  * in case 2 */ @override     public int getviewtypecount() {         return 2;     }  /** * override function, returns item return @ position */ @override     public int getitemviewtype(int position) {         //return type = tab according position         if (position == 0 || position == 4) {            return type_tab;         } else {           return type_item;         }     }

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 ...
