Using appcompat? ColorAccent in color selector doesn't seem to work
I'm trying to use "? ColorAccent" inside a text color selector element, but whenever an activated state is fired, the text shows red instead of the actual colorAccent value. I've isolated the problem to a minimum of files and posted the relevant snippets below. I also downloaded the complete project here: https://github.com/danh32/ColorAccentSelector if it helps.
1) I have a ListView for single selection mode so that its rows can be checked.
public class MainActivity extends ActionBarActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ListView listView = (ListView) findViewById(R.id.listview);
listView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
listView.setAdapter(new ItemAdapter());
}
}
2) Each row is just a CheckedTextView, so I can manipulate its textColor based on the checked state. row.xml:
<?xml version="1.0" encoding="utf-8"?>
<CheckedTextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:textSize="16sp"
android:padding="8sp"
android:textColor="@color/row_text_color" />
3) @ color / row_text_color has the following value, which should appear solid black if unchecked, and my colorAccent value when checked:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true" android:color="?colorAccent" />
<item android:color="@android:color/black" />
</selector>
4) My app theme is what should set the colorAccent value to ## ff4081 (pink A200 stuff):
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#3f51b5</item>
<item name="colorPrimaryDark">#303f9f</item>
<item name="colorAccent">#ff4081</item>
</style>
</resources>
However, when I run I see the following:
If I changed the CheckedTextView so that instead of using textcolor = "? ColorAccent" instead of using a selector, the color was the correct pink value. Is there a way to make this work inside a selector?

Thanks to fooobar.com/questions/63190 / ... for the answer, apparently you just can't use the attr link in the color selector. I ended up taking his advice and creating a new attr specific to my application called textColorSelector so that I can change my selector in the theme.
I would be happy to share more specific features if anyone finds it helpful.
EDIT: The code I used:
attrs.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<attr name="checkedTextSelector" format="reference"/>
</resources>
themes.xml (note that each child theme specifies a different "checkedTextSelector"):
<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:tools="http://schemas.android.com/tools">
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- specify enter and exit transitions -->
<item name="android:windowContentTransitions" tools:targetApi="21">true</item>
<item name="android:windowEnterTransition" tools:targetApi="21">@android:transition/explode</item>
<item name="android:windowExitTransition" tools:targetApi="21">@android:transition/explode</item>

<style name="AppTheme.Blue">

nav_row_text_color_blue.xml (other files only indicate different colors):
