Resources$NotFoundException for android.R.layout.simple_list_item_1

I am reading the book \"Android 2\" from Arno Becker and Marcus Pant. In the course of this book they develop a small android application with the reader.

I am reading the book "Android 2" from Arno Becker and Marcus Pant. In the course of this book they develop a small android application with the reader. At one point now I get an error I can't solve. I have an ListActivity which should be filled with static data. Whenever I start the activity, I get an Exception Resources$NotFoundException with the text: "File res/layout/simple_list_item_1.xml from xml type layout resource ID".

Here is the code calling the activity:

public void onClickManageContacts(View view)
{
   final Intent intent=new Intent(this,ListContacts.class);
   startActivity(intent);      
}

Here is the code of the activity:

package androidbook.amando.gui;

import androidbook.amando.R;
import android.app.ListActivity;
import android.os.Bundle;
import android.widget.ArrayAdapter;

public class ListContacts extends ListActivity {

   private static final String[] NAMES = new String[] { "Berthold Schmitz",
         "Chantal Schulze", "Bartolomäus Weissenbaum", "Jean-Paul Küppers" };

   @Override
   public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);

      setContentView(R.layout.geokontakte_auflisten);

      showContacts();
   }

   private void showContacts() {
      final ArrayAdapter<String> contactAdapter = new ArrayAdapter<String>(
            this, android.R.layout.simple_list_item_1, NAMES);
      setListAdapter(contactAdapter);
   }
}

res/layout/geokontakte_auflisten.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="vertical"
  android:layout_width="match_parent"
  android:layout_height="match_parent">
  <Spinner
    android:layout_height="wrap_content"
    android:drawSelectorOnTop="true"
    android:id="@+id/sp_sortierung"
    android:layout_width="wrap_content"
    android:entries="@array/Sortierung">
  </Spinner>
  <ListView
    android:layout_height="wrap_content"
    android:id="@+id/androi开发者_Python百科d:list"
    android:layout_width="wrap_content"
    android:textFilterEnabled="true"
    android:cacheColorHint="@color/hintergrund">
  </ListView>
  <TextView
    android:id="@+id/android:empty"
    android:layout_height="wrap_content"
    android:layout_width="wrap_content"
    android:text="@string/txt_geokontakt_auflisten_keineDaten">
  </TextView>
</LinearLayout>

The time when the exception is thrown, is after the method showContacts() finished. Here the stack trace:

The exception is not thrown, when I comment out the setListAdapter() line. The exception is also not throw, when the given array is empty and there are no list items to be displayed.

When I copy the simple_list_item_1.xml file from the SDK into my own project (res/layout), The error message changes from the above mentioned message (File res/layout/simple_list_item_1.xml from xml type layout resource ID) to "ERROR/AndroidRuntime(2609): android.content.res.Resources$NotFoundException: File res/layout/typing_filter.xml from xml type layout resource ID #0x1090069". This error is more resistant. Copying typing_filter.xml into my own projects directory doesn't change anything.

I also asked this question in the forum anddev.org, but didn't get an answer and now realized that the answer rates there aren't high.

edit: I just saw that LogCat prints a more useful stacktrace than the standard eclipse view. There seems to be a FileNotFound exception before Resources$NotFoundException is thrown:

edit2: Thank you @DArkO for your quick answer. I changed res/layout/geokontakte_auflisten.xml, but I am getting exactly the same error.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="vertical"
  android:layout_width="match_parent"
  android:layout_height="match_parent">
  <Spinner
    android:layout_height="wrap_content"
    android:drawSelectorOnTop="true"
    android:id="@+id/sp_sortierung"
    android:layout_width="wrap_content"
    android:entries="@array/Sortierung">
  </Spinner>
  <ListView
    android:layout_height="wrap_content"
    android:id="@android:id/list"
    android:layout_width="wrap_content"
    android:textFilterEnabled="true"
    android:cacheColorHint="@color/hintergrund">
  </ListView>
  <TextView
    android:id="@android:id/empty"
    android:layout_height="wrap_content"
    android:layout_width="wrap_content"
    android:text="@string/txt_geokontakt_auflisten_keineDaten">
  </TextView>
</LinearLayout>

I am using API version 10 and an android 2.3.3 emulator.


A list activity can only support if your list's id is:

android:id="@android:id/list"

just replace that one here:

 <ListView
android:layout_height="wrap_content"
android:id="@+id/android:list"
android:layout_width="wrap_content"
android:textFilterEnabled="true"
android:cacheColorHint="@color/hintergrund">
