Duplicating items with android: -


trying setup app use material design:

<style name="apptheme" parent="android:theme.material.light.darkactionbar">         <!-- customize theme here. -->         <item name="colorprimary">@color/colorprimary</item>         <item name="colorprimarydark">@color/colorprimarydark</item>         <item name="coloraccent">@color/coloraccent</item>          <item name="android:colorprimary">@color/colorprimary</item>         <item name="android:colorprimarydark">@color/colorprimarydark</item>         <item name="android:coloraccent">@color/coloraccent</item>
  • if items android: removed - colors not getting applied.
  • if items without android: removed - app crashes:

unable start activity componentinfo{com.foo.bar/com.foo.bar.mainactivity}: android.view.inflateexception: binary xml file line #9: error inflating class android.support.design.widget.tablayout

questions:

  • why have duplicate those?
  • should duplicate styles that?

edit:

the manifest file is:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"     package="com.foo.bar">      <application         android:allowbackup="true"         android:icon="@mipmap/ic_launcher"         android:label="@string/app_name"         android:supportsrtl="true"         android:theme="@style/apptheme">         <activity             android:name=".mainactivity"             android:screenorientation="portrait">             <intent-filter>                 <action android:name="android.intent.action.main"/>                  <category android:name="android.intent.category.launcher"/>             </intent-filter>

edit2

activity_main.xml:

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:app="http://schemas.android.com/apk/res-auto"     android:id="@+id/activity_main"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:orientation="vertical">      <android.support.design.widget.tablayout         android:id="@+id/tl_periods"         android:layout_width="match_parent"         android:layout_height="wrap_content"         app:tabminwidth="100dp"         app:tabmode="scrollable"/>

the theme of application not descendant of appcompat theme, whereas tablayout support packages.

you either have stick appcompat theme , views, or entirely support packages independent, otherwise such nasty issues rise.

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
