i have listview binds image & text. have been trying add floating button bottom-right of page no avail. done research there seems still no clear solution this. knows how can implement this? in xaml code , have shown have tried.

my xaml

 <?xml version="1.0" encoding="utf-8" ?>     <contentpage xmlns="http://xamarin.com/schemas/2014/forms"                  xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"                  x:class="loyaltyworx.page1"                  title="stores">         <contentpage.toolbaritems>              <toolbaritem text="about"                           icon="ic_action_more_vert.png"                          priority="0"                          order="secondary"                          clicked="toolbaritem_clicked"/>              <toolbaritem text="settings"                          icon="ic_action_more_vert.png"                          priority="0"                          order="secondary"/>          </contentpage.toolbaritems>           <listview x:name="mainlistview" hasunevenrows="true" itemtapped="mainlistview_itemtapped" separatorcolor="darkgray">             <listview.itemtemplate>                 <datatemplate>                      <imagecell imagesource="{binding image}" text="{binding name}" textcolor="black" />                   </datatemplate>              </listview.itemtemplate>         </listview>  ***//here attempted image covers whole page***         <image source="add.png"                   verticaloptions="fillandexpand"                   horizontaloptions="fillandexpand"                heightrequest="0"                widthrequest="0"                   absolutelayout.layoutbounds="1,.99, 65, 65"                   absolutelayout.layoutflags="positionproportional" >             <image.gesturerecognizers>                 <tapgesturerecognizer                   command="{binding clicknewcard}"                   commandparameter="3" />             </image.gesturerecognizers>         </image>      </contentpage>

(sorry poor english)

there's lot of problems here:

  1. if setting content of contentpage, must declare 1 element (so should use layout container stacklayout - can handle multiple children - compose page). see this topic it;
  2. you're setting absolutelayout attached properties, image not inside absolutelayout. this topic lead way use absolutelayout (i guess it's not need here).
  3. you're setting verticaloptions="fillandexpand" , horizontaloptions="fillandexpand" image view, when properties should on listview. this topic layoutoptions.

try way , tell me if works you:

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
