先上圖

前言：由於這段時間專案中需要用到這個功能，所以在此小計，以便以後方便檢視

實現的原理很簡單，就是給ListView設定一個HeanderView，當ListView資料第一行在頂部的時候，將HeanderView檢視顯示就行。

所以我們需要建立倆個HanderView的xml

第一個HeaderView佈局listview_headerview1.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    >
    <ImageView
        android:layout_width="match_parent"
        android:layout_height="240dp"
        android:background="@drawable/image"
        android:scaleType="fitXY"
        />
</LinearLayout>
 

<?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:layout_width="match_parent"
        android:layout_height="40dp"
        android:background="@android:color/darker_gray"
        android:text="好帥"
        android:gravity="center_vertical"
        />
</LinearLayout>
 

則主佈局程式碼如下

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:context="com.pengguichu.testlistheaderview.MainActivity">

    <com.handmark.pulltorefresh.library.PullToRefreshListView
        android:id="@+id/listview"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"></com.handmark.pulltorefresh.library.PullToRefreshListView>
    <include
        android:id="@+id/listview_headerview2"
        layout="@layout/listview_headerview2"></include>
</RelativeLayout>
 

PS：主佈局需要使用RL佈局，不然往上滑動時，會影響視覺效果 。

接下來就是邏輯程式碼。

思路如下：給ListView設定倆個HeaderView,--------->當滑動ListView到頂部時顯示固定頭部檢視，否則就隱藏。這裡需要注意的是，PullToRefreshListView是一個重寫的LinearLayout，所以我們需要獲取他內部巢狀的ListView，程式碼如下

ListView listView = pullToRefreshListView.getRefreshableView();

新增HeaderView程式碼

listView.addHeaderView(headerview1);
        listView.addHeaderView(headerview2);

 pullToRefreshListView.setOnScrollListener(new AbsListView.OnScrollListener() {
            @Override
            public void onScrollStateChanged(AbsListView view, int scrollState) {

            }

            @Override
            public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
                headerview_in.setVisibility(firstVisibleItem >=2 ? View.VISIBLE : View.GONE);
            }
        });

下拉重新整理以及全部程式碼我貼在下面，可以自己好好研究，不懂可以留言或者下載原始碼(原始碼在部落格最後)
