Android 如何设置expandablelist底部的页脚？

我使用了expandablelist，我想在屏幕底部设置它的页脚，但它不起作用。我附上了它的代码和截图

 <ExpandableListView
        android:layout_alignParentBottom="true"
        android:id="@+id/list_slidermenu"
        android:layout_width="260dp"
        android:layout_height="fill_parent"
        android:layout_gravity="start"
        android:background="@color/colorAccent"
        android:choiceMode="singleChoice"
        android:divider="@color/colorPrimary"
        android:dividerHeight="1dp"
        android:groupIndicator="@null"
        android:listSelector="@drawable/list_selector" >
    </ExpandableListView>

expListView = (ExpandableListView) findViewById(R.id.list_slidermenu);
        TextView textView = new TextView(this);
        textView.setText("footer");
        expListView.addFooterView(textView);

expListView=（ExpandableListView）findViewById（R.id.list\u slidermenu）；
TextView TextView=新的TextView（此）；
setText（“页脚”）；
expListView.addFooterView（文本视图）；

编辑的

View v= inflator.inflate(R.layout.your_view, null);
expandableList.addFooterView(v);

Footer

view将在列表的最后一项之后获得add。因此这是

addFooterView（）的预期输出

。如果您需要视图始终位于底部，您可以使用底部对齐的

视图
列表视图
。或者使用
页脚视图
方法，您可以使用
列表视图
填充高度，以便
