`ArrayAdapter` not working in android 2.1_问答_开发者

i have written the following code in my application:

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

where the yearlistingheader.xml file is as follows:

<?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" />

when i try and run my program i get the following error:

i am not able to understand which resource is not available. the code on line 238 is the call to getView of this arrayadapter.

Also when i use the default android layout, there seems to be no error. here is the code that gives no error:

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

what is going wrong here? thank you in advance.

Maybe some attribute of your textview is not accessible by the Program

I saw that you called style="@style/style="@style/compactview"".

Are u sure you have styles.xml in values folder.

If it is make sure you have resource element named "compactview".

Sometimes the Android tooling in eclipse fails to update values in R after changes are made, which can cause error messages like this. Selecting to clean the project fixes it.
