`ArrayAdapter`不是在Android 2.1的

Question

工作我寫了下面的代碼在我的應用程序：

headers = new ArrayAdapter<String>(context,R.layout.yearlistingheader); 

其中yearlistingheader.xml文件如下：

<?xml version="1.0" encoding="utf-8"?> 
<TextView 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/list_header_title" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:paddingTop="2dip" 
    android:paddingBottom="2dip" 
    android:paddingLeft="5dip" 
    style="@style/compactview" 
    android:textColor="#ffffff" 
    android:background="@drawable/mothlistingsectionhead" /> 

當我嘗試運行我的程序我收到以下錯誤：

我無法瞭解哪些資源不可用即 第238行的代碼是調用getView的這個arrayadapter。

此外，當我使用默認的android佈局，似乎沒有錯誤。這裏是沒有錯誤的代碼：

headers = new ArrayAdapter<String>(context,android.R.layout.simple_list_item_1); 

這裏怎麼回事？ 預先感謝您。

Answer 1

也許你的TextView的某些屬性不是由程序

Answer 2

訪問我看到你叫style="@style/style="@style/compactview""。

是否確定在values文件夾中有styles.xml。

如果確保您有名爲「compactview」的資源元素。

Answer 3

有時Eclipse中的Android工具在更改後無法更新R中的值，這會導致類似這樣的錯誤消息。選擇清理項目會修復它。
