xaml - How to do the image fill the text - the same size always - xamarin.forms -


i trying button image, , each button has text inside...but don't know xamarin forms, i'm beginner , images little while text bigger it...

i using grid...and inside 1 other grid 1 colunm , 1 row each button (image , texts) neet image (that button) size of texts inside it

enter image description here

my xml @ moment:

<!-- buttons grid-->     <grid horizontaloptions="center" margin="20,20,20,20" rowspacing="30" columnspacing="10" backgroundcolor="aquamarine" verticaloptions="fillandexpand">         <grid.rowdefinitions>             <rowdefinition height="auto"/>             <rowdefinition height="auto"/>             <rowdefinition height="auto"/>         </grid.rowdefinitions>         <grid.columndefinitions>             <columndefinition width="*"/>             <columndefinition width="*"/>         </grid.columndefinitions>    <!--one of buttons grid, there 4 others one-->   <grid grid.column="0" grid.row="1" backgroundcolor="gray">             <grid.rowdefinitions>                 <rowdefinition height="*"/>             </grid.rowdefinitions>              <image source="comochegarbtn.png" horizontaloptions="fillandexpand" grid.row="0" grid.column="0">                 <image.gesturerecognizers>                     <tapgesturerecognizer tapped="mapaclique"/>                 </image.gesturerecognizers>             </image>              <stacklayout grid.row="0" grid.column="0"  horizontaloptions="center" verticaloptions="center">                 <image source="location.png" verticaloptions="fillandexpand"/>                 <label text="como chegar" textcolor="white" horizontaloptions="center" style="{binding labelsfont}"/>             </stacklayout>           </grid>         </grid>

in android solve using wrap_content here, in xamarin forms, don't know how solve gray part grid item size

if need exact size of text width of image have use relativelayout.

in relativelayout image width use relativetoview. similar relative layout in android.

<relativelayout>              <image relativelayout.widthconstraint="{constraintexpression type=type=relativetoview, elementname=mystacklayout,property=width,factor=1}" source="comochegarbtn.png" horizontaloptions="fillandexpand" grid.row="0" grid.column="0">                 <image.gesturerecognizers>                     <tapgesturerecognizer tapped="mapaclique"/>                 </image.gesturerecognizers>             </image>              <stacklayout x:name="mystacklayout" horizontaloptions="center" verticaloptions="center">                 <image source="location.png" verticaloptions="fillandexpand"/>                 <label text="como chegar" textcolor="white" horizontaloptions="center" style="{binding labelsfont}"/>             </stacklayout> </relativelayout>

using 1 or 2 relative layouts won't affect much. if think can write custom render , create complex button in native layer.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -
