layout布局实现listview+button具体看代码：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <ListView
        android:id="@+id/menu_items"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:divider="#c9dddddd"
        android:dividerHeight="1dp"
        android:listSelector="@android:color/transparent"/>

    <Button
        android:id="@+id/menu_cancel"
        android:layout_width="match_parent"
        android:layout_height="45dp"
        android:layout_marginBottom="8dp"
        android:layout_marginTop="8dp"
        android:background="@drawable/menu_item_single"
        android:textColor="@color/menu_text"
        android:text="取消" />
</LinearLayout>

style：

<style name="ActionSheetDialog" parent="android:Theme.Dialog">
    <item name="android:windowContentOverlay">@null</item>//设置窗体内容背景
    <item name="android:windowFrame">@null</item>//是否有边框
    <item name="android:windowBackground">@android:color/transparent</item>//窗体的背景
    <item name="android:windowNoTitle">true</item>//窗体是否有背景
</style>里实现代码
