Using selector to change TextView text color

Question

I'm trying to use a TextView to define the style of a TabWidget on a tabhost.

I just created a selector for bgcolor and works fine, but i want to make a selector for textColor but the text color don't change:

This is my tab_text_selector.xml:

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

</selector>

And this is the code when i'm trying to use on a textView:

TextView txtTab=new TextView(this);
        txtTab.setTextColor(R.drawable.tab_text_selector);
        txtTab.setBackgroundResource(R.drawable.tab_bg_selector);
        txtTab.setGravity(Gravity.CENTER);
        txtTab.setText("Agregar Idea");

I know the text color must be white in any case but it doesn't.

Answer 1

1) Use tab_text_selector.xml as below and put it into res/color folder:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_selected="true" android:color="@android:color/white" />
    <item android:state_focused="true" android:color="@android:color/white" />
    <item android:state_pressed="true" android:color="@android:color/white" />
    <item android:color="#504f4f" /> <!-- default case -->
</selector>

And set it to your textview as below..

TextView tv = (TextView) findViewById(R.id.TextView1) ;
tv.setTextColor(context.getResources().getColor(R.color.tab_text_selector));

2) The Second option is If you are using textview in xml rather than using programatically then use tab_text_selector.xml as below :

<TextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:gravity="center_horizontal"
    android:text="TextView"
    android:textColor="@‌​drawable/tab_text_sel‌​ector" />

Answer 2

You have to use getColorStateList(). And for xml, see here.

I was also struggling with this problem. If you want to have use a state list, you need to declare it in the color resources folder, instead of the drawable folder, and use the setTextColor(getResources().getColorStateList(R.color.tab_text_selector)) method.

Use this way:

tab_text_selector.xml:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:state_pressed="true" android:color="#FF111111"/>  
    <item android:state_focused="true" android:color="#FF222222"/>    
    <item android:state_selected="true" android:color="#FF333333"/> 
</selector>

TextView:

TextView txtTab = new TextView(this);

XmlResourceParser xrp = getResources().getXml(R.drawable.tab_text_selector);  
try {  
    ColorStateList csl = ColorStateList.createFromXml(getResources(), xrp);  
    txtTab.setTextColor(csl);  
} catch (Exception e) {  } 

txtTab.setBackgroundResource(R.drawable.tab_bg_selector);
txtTab.setGravity(Gravity.CENTER);
txtTab.setText("Agregar Idea");

But it's better to put color in /res/color/yourcolor.xml
