推荐答案

创建一个包含要设置为页脚的文本的页脚视图布局，然后尝试

Create a footer view layout consisting of text that you want to set as footer and then try

View footerView = ((LayoutInflater) ActivityContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.footer_layout, null, false);
ListView.addFooterView(footerView);

页脚的布局可能是这样的:

Layout for footer could be something like this:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:paddingTop="7dip"
    android:paddingBottom="7dip"
    android:orientation="horizontal"
    android:gravity="center">

    <LinearLayout 
        android:id="@+id/footer_layout" 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:gravity="center"
        android:layout_gravity="center">

    <TextView 
        android:text="@string/footer_text_1" 
        android:id="@+id/footer_1" 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content" 
        android:textSize="14dip" 
        android:textStyle="bold" 
        android:layout_marginRight="5dip" />
    </LinearLayout>
</LinearLayout> 

活动类可以是:

public class MyListActivty extends ListActivity {
    private Context context = null;
    private ListView list = null;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        list = (ListView)findViewById(android.R.id.list);

        //code to set adapter to populate list
        View footerView =  ((LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.footer_layout, null, false);
        list.addFooterView(footerView);
    }
}
