这里我的代码：——-

phonebooklistview.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:orientation="vertical" >

    <EditText
        android:id="@+id/searchTxtBox"
        android:layout_width="match_parent"
        android:layout_height="40dp"
        android:layout_marginTop="65dp"
        android:hint="@string/searchHintTxt"
        android:singleLine="true"
        android:drawableLeft="@android:drawable/ic_search_category_default"
        android:drawablePadding="0dp"
        android:text="" />

    <ListView
        android:id="@android:id/list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:fadingEdge="vertical"
        android:fastScrollEnabled="true"
        android:padding="2dp"
        android:layout_below="@+id/searchTxtBox" >
    </ListView>

    <TextView
        android:id="@+id/phoneBookEmptyView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center_horizontal"
        android:layout_gravity="center_horizontal"
        android:text="@string/phoneBookEmptyMsg"
        android:textColor="@color/white"
        android:layout_below="@+id/searchTxtBox"
        android:layout_marginTop="5dp"
        android:textAppearance="?android:attr/textAppearanceMedium" />

</RelativeLayout>

并在PhoneBookList.java文件中

    listView = getListView();

    listView.setAdapter(adapter);
    listView.setTextFilterEnabled(true);
    //listView.setFastScrollEnabled(true);
    listView.setOnItemLongClickListener(this);
    listView.setItemsCanFocus(false);
    listView.setEmptyView(findViewById(R.id.phoneBookEmptyView));
    registerForContextMenu(listView);
