Description Ryan 2016-03-08 09:42:54 UTC
I'm running into a problem that seems to have been a known bug in previous versions of the support library but is meant to have been fixed. I wonder if it's now affecting Xamarin only for some reason. I have the latest support packages from the SDK manager and Nuget Support.Design package is at 23.1.1.1

I'm trying to use a drawable selector to set a custom background for the current item in a NavigationView. However the state_checked selector item is ignored completely (state_pressed works fine).

An example of the problem can be seen here http://stackoverflow.com/questions/31208179/appitembackground-attribute-doesnt-work-as-expected

And on the Android issue tracker here https://code.google.com/p/android/issues/detail?id=178697

Layout:

<android.support.design.widget.NavigationView
    android:id="@+id/nav_view"
    android:layout_height="match_parent"
    android:layout_width="wrap_content"
    android:layout_gravity="start"
    android:fitsSystemWindows="true"
    app:headerLayout="@layout/nav_header"
    app:menu="@menu/drawer_view"
    app:itemBackground="@drawable/state_list_drawer_background" />

and selector:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- Checked state (this one is the problem and never gets used) -->
    <item android:drawable="@drawable/background_checked" android:state_checked="true" />
    <!-- This is the default background color -->
    <item android:drawable="@drawable/background_normal" />
</selector>

Hi, has there been any movement on this? We have delayed implementing a custom menu for the run of the project, but we have to deliver in a couple of weeks so we need to come up with a solution soon.

Thanks for your help,
Ryan

Hi Ryan,

I don't believe this is a bug in the Xamarin Support Design Library(https://www.nuget.org/packages/Xamarin.Android.Support.Design/) as it seems to work on my end just fine.

Here's my selector named "navigationstate.xml" with the following code based on your example:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <!-- Checked state (this one is the problem and never gets used) -->
  <item android:drawable="@drawable/cheese_1" android:state_checked="true" />
  <item android:drawable="@drawable/cheese_2" android:state_pressed="true" />
  <item android:drawable="@drawable/cheese_3" android:state_activated="true" />
  <!-- This is the default background color -->
  <item android:drawable="@drawable/icon" />
</selector>

I used this repo below to try and reproduce as it already had the key items built into it:

https://github.com/xamarin/monodroid-samples/tree/master/android5.0/Cheesesquare

Now the only thing to do was to add the selector from above to the NavigationView:

    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_height="match_parent"
        android:layout_width="wrap_content"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/nav_header"
        app:menu="@menu/drawer_view"
        app:itemBackground="@drawable/navigationstate"
        />

After this, it seems that the respective "cheese_1" drawable is being displayed as the "state_checked" state here.

Here's my packages.config as well for reference:

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="Xamarin.Android.Support.Animated.Vector.Drawable" version="23.4.0.1" targetFramework="monoandroid50" />
  <package id="Xamarin.Android.Support.Design" version="23.4.0.1" targetFramework="monoandroid50" />
  <package id="Xamarin.Android.Support.v4" version="23.4.0.1" targetFramework="monoandroid50" />
  <package id="Xamarin.Android.Support.v7.AppCompat" version="23.4.0.1" targetFramework="monoandroid50" />
  <package id="Xamarin.Android.Support.v7.CardView" version="23.4.0.1" targetFramework="monoandroid50" />
  <package id="Xamarin.Android.Support.v7.RecyclerView" version="23.4.0.1" targetFramework="monoandroid50" />
  <package id="Xamarin.Android.Support.Vector.Drawable" version="23.4.0.1" targetFramework="monoandroid50" />
</packages>

Do you have a sample in which these conditions are not working for you? It seems to work out of the box on this end.
