Android ListView 中的奇怪异常

Question

我收到异常，但无法准确了解异常发生的位置。 我进行了搜索，但无法在堆栈跟踪中获取我的项目名称。

下面是我的堆栈跟踪

我的项目包名称是

com.stylingandroid.IntelligentLayout.SecondaryLayout;

我根本看不到我的包名称 在我遇到异常之前，我将其正确设置，异常是

02-13 15:39:25.756: W/System.err(379): Caused by: java.lang.RuntimeException: Your content must have a ListView whose id attribute is 'android.R.id.list'

我将 ListView Id 更改为 android:id="@id/android:list" 并在 java 代码中将适配器更改为

  setListAdapter(new ArrayAdapter<String>(this,android.R.id.list, STATE));
   getListView().setTextFilterEnabled(true);

My class extends ListActivity

public class StateList extends ListActivity{

期待您的回复。 谢谢。

Answer 1

似乎缺少资源 0x102000a。您需要从 R.java 反向引用该值并找到导致此问题的资源。

我还怀疑您使用了自己的 id，而不是 android.R.id.list 来标识布局 xml 文件中的资源。

请参阅 @+id/android:list 和@+id/list

ListView 并不像其他小部件那样直接。需要进行一些更详细的研究才能使其发挥作用。我经历了这个循环:)。

Answer 2

请在 Android 开发者论坛中查看 ListView 规范：
http://developer.android.com/resources/tutorials/views/hello -listview.html

下面的方法需要一个布局资源，用于显示列表视图中的每个项目。

setListAdapter(new ArrayAdapter<String>(this, R.layout.list_item, COUNTRIES));

list_item.xml

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:padding="10dp"
    android:textSize="16sp" >
</TextView>

因此，这里每个列表项都将显示为 TextView。

Answer 3

我也有同样的问题。我的类正在扩展 ListActivity，我更改为 Activity 并且现在正在运行。
