drawable file:

<selector xmlns:tools="http://schemas.android.com/tools" xmlns:android="http://schemas.android.com/apk/res/android"

          tools:ignore="MissingDefaultResource">

    <item

          android:color="@color/colorAccent"

          android:state_checked="true"/>

    <item android:color="#000000"

          android:state_checked="false"/>



</selector>

Gradle dependency

implementation 'androidx.appcompat:appcompat:1.0.0-alpha01'

The last item of a selector is usually without any explicit state. And that is because if can be in a lot more states than just checked or unckecked.

<selector xmlns:tools="http://schemas.android.com/tools" xmlns:android="http://schemas.android.com/apk/res/android"

          tools:ignore="MissingDefaultResource">

    <item

          android:color="@color/colorAccent"

          android:state_checked="true"/>

    <item android:color="#000000"/>



</selector>

The latest items acts as a default, fallback state.

This should be black always unless explicitely checked.

Try this, it works for me

xml--
