用XListView實現向上重新整理，向下追加資料，並且多條目載入
     
  
 
 
 開始佈局 
 此處只展示Xlistview的佈局 
 <?xml version="1.0" encoding="utf-8"?>

 package com.example.week3.Fragment; 
 import android.os.AsyncTask; import android.os.Bundle; import android.support.annotation.NonNull; import and

XListView設定上拉重新整理下拉載入和多條目載入
     
 
                首先匯入xlistviewlibrary在佈局中寫

com.bwie.xlistviewlibrary.view.XListView

可以用ctrl看看是否匯入成功

xlistView.setPullLoadEnable(true);

可以上拉重新整理更多

init 

  
 

    

    
    
AndroidStudio xlistview 多條目載入
     
  
  
  
 思路: 1 BaseAdapter 介面卡 2 多個條目佈局檔案 3 介面卡方法 
 在這裡插入程式碼片
```public class MyAdapter extends BaseAdapter {

TabLayout+ViewPager+Fragment實現多條目載入（多個介面）

多條目載入
     
  
  
  
 需要重寫getViewTypeCount,getItemViewType兩個方法 
   private void initData() {
        //這個過程是在子線中,請求網路比較慢,有可能8秒;
        new MAsyncTask().execute(url);

RecyclerView多條目載入（網路請求資料）
     
 
                
RecyclerView多條目載入和ListView的多條目載入用法是一樣的，程式碼如下：
1.匯入RecyclerView或XRecyclerView的依賴包（自己按照需求匯入依賴包，下面RecyclerView可以替換成XRecyclerView）XRecyclerVi 

  
 

    

    
    
Recyclerview 實現多條目載入
     
 
							
							
							

這種佈局樣式,相信很多開發者都會用到 
今天我是用RecyclerView來實現這個多種Item的載入. 
其實最關鍵的是要複寫RecyclerView的Adapter中的getItemViewType()方法  
這個方法就根據條件返回條目的型別

一般有
