android - android.R.layout.simple_list_item_1 的资源 $NotFoundException

Question

我正在阅读 Arno Becker 和 Marcus Pant 合着的《Android 2》一书。在本书的类(class)中，他们与读者一起开发了一个小型安卓应用程序。现在有一次我遇到了一个我无法解决的错误。我有一个 ListActivity 应该填充静态数据。每当我开始 Activity 时，我都会收到一个异常 Resources$NotFoundException，其文本为:“File res/layout/simple_list_item_1.xml from xml type layout resource ID”。

这是调用 Activity 的代码:

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

这是 Activity 的代码:

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/android: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>

抛出异常的时间是在 showContacts() 方法完成之后。这里是堆栈跟踪:

当我注释掉 setListAdapter() 行时，没有抛出异常。当给定数组为空且没有要显示的列表项时，也不会抛出异常。

当我将SDK中的simple_list_item_1.xml文件复制到我自己的项目(res/layout)中时，错误信息从上面提到的信息(File res/layout/simple_list_item_1.xml from xml type layout resource ID)变为“错误/AndroidRuntime(2609):android.content.res.Resources$NotFoundException:来自 xml 类型布局资源 ID #0x1090069 的文件 res/layout/typing_filter.xml”。这个错误更能抵抗。将 typing_filter.xml 复制到我自己的项目目录中不会改变任何内容。

我也在论坛 anddev.org 上问过这个问题，但没有得到答案，现在意识到那里的回答率不高。

编辑:我刚刚看到 LogCat 打印出比标准 eclipse View 更有用的堆栈跟踪。在抛出 Resources$NotFoundException 之前似乎有一个 FileNotFound 异常:

编辑2:感谢@DArkO 的快速回答。我更改了 res/layout/geokontakte_auflisten.xml，但我得到了完全相同的错误。

<?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>

我使用的是 API 版本 10 和 android 2.3.3 模拟器。

Answer 1

列表 Activity 仅在您的列表 ID 为以下时才支持:

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

只需在这里替换那个:

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