android - how to change font color in selected/focused ListView items?

Question

I am struggling with this which apparently is a very simple effect but incredibly haven't found any intutitive way for doing it in Android.

I have a ListView and I managed to customize the background images so the selected item gets highlighted by getting a new background drawable. This I do creating a new style where I set the android:listSelector attribute to point a StateListDrawable where I have specified which drawables to use for every state.

However each ListView item is a LinearLayout where i have two TextViews. My goal is to be able to change the text color of these child views whenever the parent is selected or pressed, at the same time as the background drawable does. I know there is a ColorStateList but haven't been succesful setting that up.

Has anybody succeed getting something like this to work?

Thanks.

Answer 1

Neither of these are possible answers when your ListView is compromised of a layout that has multiple views. You need to set your child views to:

android:duplicateParentState="true"

Now you can use the methods others have described above to declare your TextViews' colors using a selector such as:

android:textColor="@drawable/my_row_selector"

and I'm sure you're aware, but the selector can be as simple as:

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

As you can see, @color values are allowed. Hope this helps.

Also - android:state_pressed is used in conjunction with the AdapterView.OnItemClickListener.
