添加ddHeaderView注意问题

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout  xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent"android：id=“@+id=header” 
    android:layout_height="fill_parent" > 
    <Button  
        android:id="@+id/testButton" 
        android:layout_width="fill_parent"  
        android:layout_height="wrap_content" 
        android:text="Income"  
        android:textSize="15dip" 
        android:layout_weight="1" /> 
</LinearLayout>

上面是head.xml

你如果ListView lv = getListView(); 
lv.addHeaderView(findViewById(R.layout.header)); 就错了

通常ListView lv = getListView(); 
LayoutInflater inflater = getLayoutInflater(); 
ViewGroup header = (ViewGroup)inflater.inflate(R.layout.header, lv, false); 
lv.addHeaderView(header, null, false);
