Inflate you xml

    LayoutInflater inflater = LayoutInflater.from(this);
    View view = inflater.inflate(R.layout.linear_layout, null);

    textView2 = (TextView) view.findViewById(R.id.textView2);

Try this, hope it would help you out

SharedPreferences prefs;
String x = prefs.getString("tel",defaultString value);
textView.setText(x);

The reason why a simple findViewById in your EditPreferences.onCreate doesn't work is because your layout with the TextView is created inside of a ListView and there is a delay before that actually happens when the activity is launched.

I'm not sure this is the best way, but one way to handle the event of ListView item population is to handle the OnHierarchyChange event for the ListView object. If you put this in your onCreate, after the preference layout has been loaded from what I assume is a call to addPreferencesFromResource, it should work.

ListView list = (ListView) findViewById(android.R.id.list);
list.setOnHierarchyChangeListener(new ViewGroup.OnHierarchyChangeListener() {
    @Override
    public void onChildViewAdded(View parent, View child) {
        TextView text = (TextView) child.findViewById(R.id.textView2);
        if (text != null) {
            text.setText("Something else here");
        }
    }

    @Override
    public void onChildViewRemoved(View view, View view2) {
    }
});
