Answer 1

Basically no, it's a bug that was fixed in Lollipop. The suggestion (until you can minSdkVersion=21) is to create a different drawable XML file for each different color you need (and have that as a theme attribute, I assume).

The duplicate question, answers and comments discuss this bug: How to reference colour attribute in drawable?

Answer 2

I had the same problem. The problem is that you are using ?attr/ in your drawable. Replace that with a @color or @drawable and it should go away. This does unfortunately mean that you have to bundle a drawable for each of your themes, it is a lot cleaner in lollipop.

Check out this commit of mine on the project I'm working on, it was to resolve exactly this problem.

You could create a drawable-v21 folder and put a drawable under it in hopes of a good time when you can support v21+ but I have chosen to go the other route and bundle different color resources (something you can see in the main branch, I have teal and default green colors).

Answer 3

I was finally able to fix the issue. I will post answer so that it may help future readers.

The problem is that we can't give attr values to item and gradient. I got the issue fixed by taking different xml files for colors.

I ended up using different versions of list_selector_white_1 and _2.xml to:

<!-- Selector style for listrow -->
<item android:drawable="@drawable/gradient_bg_white_1" android:state_pressed="false" android:state_selected="false"/>
<item android:drawable="@drawable/gradient_bg_hover_1" android:state_pressed="true"/>
<item android:drawable="@drawable/gradient_bg_hover_1" android:state_pressed="false" android:state_selected="true"/>

Similarly, I changed gradient_bg_hover and gradient_bg_white to different versions.

Finally, I created an attribute list_selector with format integer and used it in fragment xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:background="?attr/list_selector" >
    ....Other views here....

I am waiting for the time when I can support API level >= 21 in my app, in order to remove all these hacks.
