android - Textcolor selector not working

I did this before. I copy-pasted. I copy-pasted many other examples from the net. I simply cannot make the textcolor selector work. It sets the default color to the textview, but it won't change if you click on the textview. The settings_selector for the background works fine.

This is the layout:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/settings_selector"
    android:clickable="true"
    android:id="@+id/llRecentChanges"
    android:paddingTop="5dp"
    android:paddingBottom="5dp"
    android:paddingLeft="5dp">
      <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="vertical"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/llRecentChanges2"
        android:layout_weight="1"
        android:layout_gravity="center_vertical">
    <TextView
        android:id="@+id/tvAbout"
        android:text="@string/settings_recentchanges"
        android:gravity="center_vertical"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="16dp"
        android:textColor="@drawable/settings_selector_txt" >
    </TextView>
    <TextView
        android:id="@+id/tvAbout2"
        android:text="@string/settings_recentchanges2"
        android:gravity="center_vertical"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="@drawable/settings_selector_txt"
        android:textSize="10dp">
    </TextView>
    </LinearLayout>

</LinearLayout>

This is the settings_selector_txt xml:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_focused="true" 
          android:state_pressed="false" 
          android:color="#FFFFFF" />
    <item android:state_focused="true" 
          android:state_pressed="true"
          android:color="#ffa800" />
    <item android:state_focused="false" 
          android:state_pressed="true"
          android:color="#ffa800" />
    <item android:color="#FFFFFF" />
</selector>

or this

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:state_selected="true" android:color="#444"/>
    <item android:state_focused="true" android:color="#444"/>
    <item android:state_pressed="true" android:color="#444"/>
    <item android:color="#ccc"/>

</selector>

or this

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_focused="true" android:state_pressed="false" android:color="#ffffff" />
    <item android:state_focused="true" android:state_pressed="true" android:color="#000000" />
    <item android:state_focused="false" android:state_pressed="true" android:color="#000000" />
    <item android:color="#ffffff" />
</selector>

None of them is working. Putting the selector xml to the color folder is also no solution. Any ideas?

Make sure your TextView is ready for listening the states you are applying for. For instance, to be able to reach the "state_pressed" your textView should be clickable:

android:clickable="true"

EDIT: There we go. This layout does the job. Note that the View that gathers the click event is the linearLayout, but the TextView reproduces it because of "duplicateParentState" set to true. The color selector would take care of the colors for the different states.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/testLlayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:clickable="true" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="@drawable/textview_selector"
        android:duplicateParentState="true"
        android:text="TextView" />

</LinearLayout>

And here is the code for the color selector.

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:state_selected="true" android:color="#444"/>
    <item android:state_focused="true"  android:color="#444"/>
    <item android:state_pressed="true"  android:color="#444"/>
    <item android:color="#ccc"/>

</selector>

That should be it.
