android - RelativeLayout in StackLayout Width Calculation -


i've got odd problem relativelayouts nested in stacklayout, appears stacklayout calculates width of elements should using relativelayout width , relativelayout recalculates again afterwards. results in child control being relative width squared, following controls being placed @ relative width.

is bug or doing wrong?

example

<?xml version="1.0" encoding="utf-8" ?> <contentpage x:class="myclass"              xmlns="http://xamarin.com/schemas/2014/forms"              xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"              >    <stacklayout orientation="horizontal" backgroundcolor="blue">     <relativelayout>       <contentview backgroundcolor="red"            relativelayout.xconstraint=                 "{constraintexpression type=relativetoparent,                                       property=width,                                       factor=0}"           relativelayout.widthconstraint=                 "{constraintexpression type=relativetoparent,                                       property=width,                                       factor=0.707106}"           relativelayout.yconstraint=                   "{constraintexpression type=relativetoparent,                                         property=height,                                         factor=0}"           relativelayout.heightconstraint=                 "{constraintexpression type=relativetoparent,                                       property=height,                                       factor=1}">        </contentview>      </relativelayout>     <relativelayout>       <contentview backgroundcolor="green"            relativelayout.xconstraint=                 "{constraintexpression type=relativetoparent,                                       property=width,                                       factor=0}"           relativelayout.widthconstraint=                 "{constraintexpression type=relativetoparent,                                       property=width,                                       factor=0.5}"           relativelayout.yconstraint=                   "{constraintexpression type=relativetoparent,                                         property=height,                                         factor=0}"           relativelayout.heightconstraint=                 "{constraintexpression type=relativetoparent,                                       property=height,                                       factor=1}">        </contentview>      </relativelayout>    </stacklayout> </contentpage>

screen shot

the 2 relativelayout elements confusing factor, , fact each specified @ x position 0 relative parent stacklayout, seems conflict.

it seems comments if each relativelayout expected half width of parent stacklayout, layout simplified eliminating 1 of relativelayout elements.

the specified widths of child strips divided 2 width of each intended relative parent stacklayout, , x positions set relative parent position them horizontally.

here came with:

does produce closer expected?

caching - How to check if a url path exists in the service worker cache -

i need check if particular url path exists in service worker cache. example, suppose url is: /myserviceworker/service?a=110&b=70 this url exists in cache, there many of them different values of , b. now, suppose want refresh of these urls, how can that? i want know how access key values service worker cache. if know key, plan follows: var url = new url(key); if(url.pathname === "\/myserviceworker/service") refetch key but not sure how cache key , in format is. mean, string or url? cache api has match() method returns promise resolving in response object if match or undefined if no match exists. second parameter object can specify ignoresearch not take account url parameters. the ignoresearch option supported firefox ( chrome status here ). in other hand, retrieve cache entries, can use keys() method.

Redirect to a HTTPS version using .htaccess -

i need modify .htaccess file redirect urls https version without "www". http://example.com --> https://example.com http://www.example.com --> https://example.com https://www.example.com --> https://example.com this how .htaccess file looks like: rewriteengine on rewritecond %{request_filename} !-d rewritecond %{request_filename} !-f rewriterule ^(.*)$ redirect.php?id=$1&page=$2 [qsa,l] what modifications need make .htaccess in order forward https without "www"? it depends on doing current code. looks file called redirect trying display php page seo friendly url. think might confusing people. anyway, need , force https without www, need 1 more rule above. also second rule needs two capture groups in rewriterule test string because wanting 2 different values using $1 , $2 references. rewriteengine on #rediect www non www and/or http https --- combinations. rewritecond %{http_host} !^example\.com [nc,or] rewritecond %{https} !^
