Using selector to change TextView text color

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.

Solution

  • 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.
