创建一个由要设置为页脚的文本组成的页脚视图布局,然后尝试

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:

<?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> 

活动类可能是:

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);
    }
}

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);

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> 

The activity class could be:

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);
    }
}

这里的答案有点过时了。尽管代码保持不变,但行为发生了一些变化。

public class MyListActivity extends ListActivity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        TextView footerView = (TextView) ((LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.footer_view, null, false);
        getListView().addFooterView(footerView);
        setListAdapter(new ArrayAdapter<String>(this, getResources().getStringArray(R.array.news)));
    }
}

有关 addFooterView() 方法的信息

添加一个固定视图以显示在列表底部。如果addFooterView()被多次调用,视图将按照添加的顺序显示。如果需要,使用此调用添加的视图可以获得焦点。

上面的大多数答案都强调了非常重要的一点 -

addFooterView() 必须在调用 setAdapter() 之前调用。这样 ListView 就可以用一个也能处理页眉和页脚视图的光标来包装所提供的光标。

从 Kitkat 开始,情况发生了变化。

注意:首次引入时,只能在使用 setAdapter(ListAdapter) 设置适配器之前调用此方法。从 KITKAT 开始,可以随时调用此方法。如果 ListView 的适配器不扩展 HeaderViewListAdapter,它将使用 WrapperListAdapter 的支持实例进行包装。

文档

Answers here are a bit outdated. Though the code remains the same there are some changes in the behavior.

public class MyListActivity extends ListActivity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        TextView footerView = (TextView) ((LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.footer_view, null, false);
        getListView().addFooterView(footerView);
        setListAdapter(new ArrayAdapter<String>(this, getResources().getStringArray(R.array.news)));
    }
}

Info about addFooterView() method

Add a fixed view to appear at the bottom of the list. If addFooterView() is called more than once, the views will appear in the order they were added. Views added using this call can take focus if they want.

Most of the answers above stress very important point -

addFooterView() must be called before calling setAdapter().This is so ListView can wrap the supplied cursor with one that will also account for header and footer views.

From Kitkat this has changed.

Note: When first introduced, this method could only be called before setting the adapter with setAdapter(ListAdapter). Starting with KITKAT, this method may be called at any time. If the ListView's adapter does not extend HeaderViewListAdapter, it will be wrapped with a supporting instance of WrapperListAdapter.

我知道这是一个非常老的问题,但我在这里用谷歌搜索,发现提供的答案并不是100%令人满意,因为正如 gcl1 提到的 - 这样页脚并不是真正的屏幕页脚 - 它只是一个“附加组件” ”到列表中。

底线 - 对于其他可能在这里谷歌搜索方式的人 - 我在这里找到了以下建议: ListFragment 下面的固定且始终可见的页脚

尝试执行以下操作,其中重点是 XML 中首先列出的按钮(或任何页脚元素) - 然后将列表添加为“layout_above”:

<RelativeLayout>

<Button android:id="@+id/footer" android:layout_alignParentBottom="true"/> 
<ListView android:id="@android:id/list" **android:layout_above**="@id/footer"> <!-- the list -->

</RelativeLayout>

I know this is a very old question, but I googled my way here and found the answer provided not 100% satisfying, because as gcl1 mentioned - this way the footer is not really a footer to the screen - it's just an "add-on" to the list.

Bottom line - for others who may google their way here - I found the following suggestion here: Fixed and always visible footer below ListFragment

Try doing as follows, where the emphasis is on the button (or any footer element) listed first in the XML - and then the list is added as "layout_above":

<RelativeLayout>

<Button android:id="@+id/footer" android:layout_alignParentBottom="true"/> 
<ListView android:id="@android:id/list" **android:layout_above**="@id/footer"> <!-- the list -->

</RelativeLayout>

如果 ListView 是 ListActivity 的子级:(

getListView().addFooterView(
    getLayoutInflater().inflate(R.layout.footer_view, null)
);

在 onCreate() 内)

If the ListView is a child of the ListActivity:

getListView().addFooterView(
    getLayoutInflater().inflate(R.layout.footer_view, null)
);

(inside onCreate())

您要在其中添加列表视图页脚的活动,我还在列表视图页脚单​​击时生成了一个事件。

  public class MainActivity extends Activity
{

        @Override
        protected void onCreate(Bundle savedInstanceState)
         {

            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);

            ListView  list_of_f = (ListView) findViewById(R.id.list_of_f);

            LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);

            View view = inflater.inflate(R.layout.web_view, null);  // i have open a webview on the listview footer

            RelativeLayout  layoutFooter = (RelativeLayout) view.findViewById(R.id.layoutFooter);

            list_of_f.addFooterView(view);

        }

}

活动主文件

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/bg" >

    <ImageView
        android:id="@+id/dept_nav"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/dept_nav" />

    <ListView
        android:id="@+id/list_of_f"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/dept_nav"
        android:layout_margin="5dp"
        android:layout_marginTop="10dp"
        android:divider="@null"
        android:dividerHeight="0dp"
        android:listSelector="@android:color/transparent" >
    </ListView>

</RelativeLayout>

The activity in which you want to add listview footer and i have also generate an event on listview footer click.

  public class MainActivity extends Activity
{

        @Override
        protected void onCreate(Bundle savedInstanceState)
         {

            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);

            ListView  list_of_f = (ListView) findViewById(R.id.list_of_f);

            LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);

            View view = inflater.inflate(R.layout.web_view, null);  // i have open a webview on the listview footer

            RelativeLayout  layoutFooter = (RelativeLayout) view.findViewById(R.id.layoutFooter);

            list_of_f.addFooterView(view);

        }

}

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/bg" >

    <ImageView
        android:id="@+id/dept_nav"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/dept_nav" />

    <ListView
        android:id="@+id/list_of_f"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/dept_nav"
        android:layout_margin="5dp"
        android:layout_marginTop="10dp"
        android:divider="@null"
        android:dividerHeight="0dp"
        android:listSelector="@android:color/transparent" >
    </ListView>

</RelativeLayout>

在这个问题中,最佳答案对我不起作用。之后我发现这个方法来显示listview页脚,

LayoutInflater inflater = getLayoutInflater();
ViewGroup footerView = (ViewGroup)inflater.inflate(R.layout.footer_layout,listView,false);
listView.addFooterView(footerView, null, false);

并创建新的布局调用footer_layout

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <TextView
        android:id="@+id/tv"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Done"
        android:textStyle="italic"
        android:background="#d6cf55"
        android:padding="10dp"/>
</LinearLayout>

如果不起作用请参考这篇文章听到

In this Question, best answer not work for me. After that i found this method to show listview footer,

LayoutInflater inflater = getLayoutInflater();
ViewGroup footerView = (ViewGroup)inflater.inflate(R.layout.footer_layout,listView,false);
listView.addFooterView(footerView, null, false);

And create new layout call footer_layout

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <TextView
        android:id="@+id/tv"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Done"
        android:textStyle="italic"
        android:background="#d6cf55"
        android:padding="10dp"/>
</LinearLayout>

您可以使用 stackLayout,在此布局内您可以将列表放在框架中,例如:

<StackLayout VerticalOptions="FillAndExpand">
            <ListView  ItemsSource="{Binding YourList}"
                       CachingStrategy="RecycleElement"
                       HasUnevenRows="True">

                <ListView.ItemTemplate>
                    <DataTemplate>
                        <ViewCell >
                            <StackLayout  Orientation="Horizontal">
                                <Label Text="{Binding Image, Mode=TwoWay}" />

                            </StackLayout>
                        </ViewCell>
                    </DataTemplate>
                </ListView.ItemTemplate>
            </ListView>
            <Frame BackgroundColor="AliceBlue" HorizontalOptions="FillAndExpand">
                <Button Text="More"></Button>
            </Frame>
        </StackLayout>

这是结果:

在此处输入图像描述

you can use a stackLayout, inside of this layout you can put a list a frame, for example:

<StackLayout VerticalOptions="FillAndExpand">
            <ListView  ItemsSource="{Binding YourList}"
                       CachingStrategy="RecycleElement"
                       HasUnevenRows="True">

                <ListView.ItemTemplate>
                    <DataTemplate>
                        <ViewCell >
                            <StackLayout  Orientation="Horizontal">
                                <Label Text="{Binding Image, Mode=TwoWay}" />

                            </StackLayout>
                        </ViewCell>
                    </DataTemplate>
                </ListView.ItemTemplate>
            </ListView>
            <Frame BackgroundColor="AliceBlue" HorizontalOptions="FillAndExpand">
                <Button Text="More"></Button>
            </Frame>
        </StackLayout>

this is the result:
