I’m trying to implement the Color State List Resources in my android application, following Android developer guide Color State List Resource | Android Developers. So I created two resource files button_text.xml and button_background.xml in the directory res/color/ and referred them in the with @color/button_text and @color/button_background respectively in the activity_main.xml. Here’s the layout code:
<Button
android:id="@+id/myButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/app_name"
android:layout_marginTop="150dp"
android:layout_gravity="center"
android:textColor="@color/button_text"
android:background="@color/button_background"/>
On running the App, I’m getting a Resources Not Found Exception in the logs as shown below:
Process: com.example.myanimation, PID: 29254

I’ve tried to clean and rebuild the project but it didn’t work. Also, putting the xml files in res/drawable/ instead of res/color/ is showing the same error.Please help solving the issue. Thanks in advance!
EDIT:
Here is the button_text.xml file code:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="#000"
android:state_pressed="true"/>
<item android:color="#fff"
android:state_activated="true"/>
</selector>
And, button_background.xml file code:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="#fff"
android:state_pressed="true"/>
<item android:color="#000"
android:state_activated="true"/>
</selector>

Answer
So, here it is. Please read the full answer. The android:background attribute does not supports the Color State List unlike android:textColor. To make android:background property work, you need State List Drawables. Thus, instead of res/color/ create the file in res/drawable/ directory. Here’s the code:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@color/white"
android:state_pressed="true"/>
<item android:drawable="@color/black"
android:state_activated="true"/>
</selector>
Note the use of android:drawable instead of android:color. Android will use the color resource and make a drawable out of it. To finish this off, you need to add the color resources to your res/values/colors.xml file.
