No resource found that matches given name in main.xml

Question

This is really starting to drive me crazy.

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@id+/textview"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:text="@string/hello"/> 

Produces the following error message: "Error: no resource found that matches the given name (at 'id' with value '@id+/textview').

This is copy and pasted from the Android hello world example.

Answer 1

It's just a small typo; you need to put the '+' after the '@', not after 'id':

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/textview"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:text="@string/hello"/> 

Answer 2

@+id not @id+. Seems the tutorial is wrong!
