android - In a fragment,when an image is set as the background of a RelativeLayout in ScrollView, the RelativeLayout is misbehaving -


i have activity layout:

<?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     android:id="@+id/fragment_container"     android:layout_width="match_parent"     android:layout_height="match_parent"     tools:context=".activities.mainactivity" />

then have fragment layout, transacting in fragment_container of activity:

<?xml version="1.0" encoding="utf-8"?> <scrollview xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/scroll_view"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:fillviewport="true">      <relativelayout         android:id="@+id/relative_layout"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:background="@drawable/bg_login">       </relativelayout>  </scrollview>

the drawable bg_login is: bg_login strange thing happening is, background image(bg_login) hides content in relativelayout, in preview pane when run app. can't find out why happening! please help.

i dont know want do, want have multiple background in relative layouts when scrolled or not. assuming you, scroll view when have children element background not best practice. scoll view must set children parent have background practice. may can :

<?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android"   android:layout_width="match_parent"   android:layout_height="match_parent" android:background="@drawable/bg_login"> <scrollview     android:id="@+id/scroll_view"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:fillviewport="true">      <relativelayout         android:id="@+id/relative_layout"         android:layout_width="match_parent"         android:layout_height="wrap_content">       </relativelayout>  </scrollview> </relativelayout>

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 ...
