How to change color for item selected in Gallery

I've done a Gallery view composed by just textviews as numbers. By default if I don't set any colors the item in the centre is black. I want to change it.

Using a selector it doesn't work, any ideas?

UPDATE: if I try to use a selector also the default behavior gone and I can see only grey textview

So, this is the getVIew of my TextAdapter that extends BaseAdapter

 public View getView(int position, View convertView, ViewGroup parent) {
            TextView t = new TextView(mContext);
            int val = position + 1;
            t.setText("" + val);
            t.setTextSize(30f);
            t.setTextColor(R.drawable.numericgallery_selector);

            return t;
 }

and this is my selector.

<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:state_开发者_开发问答selected="true" android:color="#FDF132"></item>

    <item android:state_selected="false" android:color="#CADDCD"></item>

    <item android:color="#FFFFFF"></item>
</selector>

but it doen't work.... :(

I found my old post with no solution. So I tell you how I worked it out.

t.setTextColor(mContext.getResources().getColorStateList(R.drawable.numericgallery_selector));

Inflate the TextView to use inside the gallery. Then it does not require to change any thing dynamically.

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:textSize="12sp"
    **android:textColor="@drawable/tracker_selected_color"**
    android:id="@+id/textview_tracker_item" 
    android:textStyle="bold"
    />

and then try tracker_selected_color.xml

<item android:state_selected="true" android:color="#FDF132"></item>

<item android:state_selected="false" android:color="#CADDCD"></item>

<item android:color="#FFFFFF"></item>
