c# - Android custom viewgroup not rendering children -


i trying write custom viewgroup duplicate lot across layout files. simple one, 2 textboxes placed within linearlayout vertical orientation , padding. worth mentioning use xamarin develop application, don't think issue xamarin specific. implementation follows: 

[register("qube.applistitem")] class applistitem : linearlayout {     private string m_label;     private string m_value;     private int m_labelsize;     private int m_valuesize;     private int m_horizontalpadding;     private int m_verticalpadding;     private valuetype m_valuetype;      private textview m_labelview;     private textview m_valueview;      public applistitem(context context) : this(context, null)     {     }      public applistitem(context context, iattributeset attrs) : this(context, attrs, 0)     {     }      public applistitem(context context, iattributeset attrs, int defstyleattr) : base(context, attrs, defstyleattr)     {         initialize(context, attrs);     }      private void initialize(context context, iattributeset attrs)     {         var = context.obtainstyledattributes(attrs, resource.styleable.applistitem, 0, 0);          m_label = a.getstring(resource.styleable.applistitem_label);         m_value = a.getstring(resource.styleable.applistitem_value);         m_labelsize = a.getdimensionpixeloffset(resource.styleable.applistitem_labelsize, resource.dimension.font_small);         m_valuesize = a.getdimensionpixeloffset(resource.styleable.applistitem_valuesize, resource.dimension.font_medium);         m_horizontalpadding = a.getdimensionpixeloffset(resource.styleable.applistitem_horizontalpadding, resource.dimension.row_padding);         m_verticalpadding = a.getdimensionpixeloffset(resource.styleable.applistitem_verticalpadding, resource.dimension.info_list_padding);         m_valuetype = (valuetype)a.getint(resource.styleable.applistitem_valuetype, (int)valuetype.string);          a.recycle();          orientation = orientation.vertical;         clickable = true;         setpadding(m_horizontalpadding, m_verticalpadding, m_horizontalpadding, m_verticalpadding);          if (build.version.sdkint >= buildversioncodes.honeycomb)         {             // if we're running on honeycomb or newer, can use theme's             // selectableitembackground ensure view has pressed state             typedvalue outvalue = new typedvalue();             context.theme.resolveattribute(android.resource.attribute.selectableitembackground, outvalue, true);             setbackgroundresource(outvalue.resourceid);         }          buildview();     }      private void buildview()     {         m_labelview = new textview(context);         m_labelview.layoutparameters = new viewgroup.layoutparams(viewgroup.layoutparams.matchparent, viewgroup.layoutparams.wrapcontent);         m_labelview.textsize = m_labelsize;         m_labelview.text = m_label;         addview(m_labelview);          if (m_valuetype == valuetype.edittext)             m_valueview = new edittext(context);         else             m_valueview = new textview(context);          m_valueview.layoutparameters = new viewgroup.layoutparams(viewgroup.layoutparams.matchparent, viewgroup.layoutparams.wrapcontent);         m_valueview.textsize = m_valuesize;         m_valueview.text = m_value;         addview(m_valueview);     }      protected override void onmeasure(int widthmeasurespec, int heightmeasurespec)     {         base.onmeasure(widthmeasurespec, heightmeasurespec);     }      protected override void onlayout(bool changed, int l, int t, int r, int b)     {         base.onlayout(changed, l, t, r, b);     }      public string label     {         { return m_label; }         set         {             m_label = value;             m_labelview.text = value;             invalidate();             requestlayout();         }     }      public string value     {         { return m_valueview.text; }         set         {             m_valueview.text = value;             m_value = value;             invalidate();             requestlayout();         }     }      public enum valuetype     {         string, edittext     } }

the expected behavior is, said, 2 textboxes stacked on top of each other, however, actual behavior view height 0 (if android:layout_height="wrap_content"). setting layout_height 20dp manually shows blank view of height.

okay, mistake made silly one, expected. when dimensions typedarray, default value pass in resource id's instead of actual values associated id's. example: 

m_labelsize = a.getdimensionpixeloffset(resource.styleable.applistitem_labelsize, resource.dimension.font_small);

should be

m_labelsize = a.getdimensionpixeloffset(resource.styleable.applistitem_labelsize, resources.getdimensionpixeloffset(resource.dimension.font_small));

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...
