Programmatically Set Layout Params in Android v7.0 vs. Android 5.0 -


background

in android app, add, remove, , manipulate elements of rows in table programmatically. need set layout parameters of elements in tablerow() upon these table manipulation events.

problem

after migrating android 5.0 android 7.0 , running app on different tablet, table row's not reflect layout param's defined.

to clarify:

configuration 1:

  • hardware: samsung galaxy tab4
  • android version: 5.0.2
  • result: table row's formatted correctly

configuration 2

  • hardware: samsung galaxy tab s2

  • android version: 7.0

  • result: table row's not formatted

code sample

//define layout parameters rowlayoutparams = new tablerow.layoutparams(tablerow.layoutparams.match_parent, tablerow.layoutparams.wrap_content); tablelayoutparams = new tablelayout.layoutparams(tablelayout.layoutparams.match_parent, tablelayout.layoutparams.wrap_content); edittextlayoutparams = new tablerow.layoutparams(100, 40); tvlayoutparams = new tablerow.layoutparams(tablerow.layoutparams.wrap_content, tablerow.layoutparams.wrap_content);  //create new table tow tablerow = new tablerow(getactivity()); tablerow.setlayoutparams(rowlayoutparams);  //define margins int etmargin1 = (int)getactivity().getresources().getdimension(r.dimen.etmargin1); int etmargin2 = (int)getactivity().getresources().getdimension(r.dimen.etmargin2);  int tvmargin1 = (int)getactivity().getresources().getdimension(r.dimen.tvmargin1); int tvmargin2 = (int)getactivity().getresources().getdimension(r.dimen.tvmargin2);   if(editable) {     //create edit texts     edittext exampleet = new edittext(getactivity());     edittextlayoutparams.setmargins(etmargin1,5,etmargin2,5);     exampleet.setlayoutparams(edittextlayoutparams);     tablerow.setlayoutparams(rowlayoutparams);     tablerow.addview(exampleet); } else {     //create text views     textview exampletv = new textview(getactivity());      //set layout params     tvlayoutparams.setmargins(tvmargin1,5,tvmargin2,5);     exampletv.setlayoutparams(tvlayoutparams);      tablerow.setlayoutparams(rowlayoutparams);     tablerow.addview(exampletv); }

further specification

note in code sample edit text's vs. text views. edit text elements not formatted properly. text view margins format expected.

this ended being 2 part solution revolved around different screen sizes of tablets. android version not factor.

part 1 define row layout width , height parameters in terms of density independent pixels rather hard-coded values

int etheight = (int)getactivity().getresources().getdimension(r.dimen.etheight); int etwidth = (int)getactivity().getresources().getdimension(r.dimen.etwidth);  edittextlayoutparams = new tablerow.layoutparams(etwidth, etheight);

where in dimens.xml

<dimen name="etheight">40dp</dimen> <dimen name="etwidth">100dp</dimen>

part 2 change table width dimension referenced xml table definition in layout file. margins in fact formatting correctly, table large screen , created illusion elements packed left side of table.

the question whether design layout smaller tablet , waste screen space on larger tablet, or create multiple layout/dimension files support different tablet sizes. but, topic different thread.

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
