首先，寫一個xml檔案，moredata.xml，該檔案即定義了放在listview底部的檢視：

<?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" >

<Button

android:id="@+id/bt_load"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:text="載入更多資料" />

<ProgressBar

android:id="@+id/pg"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_gravity="center_horizontal"

android:visibility="gone"

/>

</LinearLayout>

寫一個item.xml，大家應該很熟悉了。用來定義listview的每個item的檢視。

<?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" >

<TextView

android:id="@+id/tv_title"

android:textSize="20sp"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_marginTop="5dp"

/>

<TextView

android:textSize="12sp"

android:id="@+id/tv_content"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_marginTop="5dp"

/>

</LinearLayout>

main.xml就不貼了，整個主介面就一個listview。

直接先看下Activity的程式碼，在裡面實現分頁效果。

package com.notice.moredate;

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

handler = new Handler();

// 用map來裝載資料，初始化10條資料

// 加上底部View，注意要放在setAdapter方法前

lv.addFooterView(moreView);

lv.setAdapter(mSimpleAdapter);

// 繫結監聽器

bt.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

pg.setVisibility(View.VISIBLE);// 將進度條可見

handler.postDelayed(new Runnable() {

@Override

public void run() {

loadMoreDate();// 載入更多資料

bt.setVisibility(View.VISIBLE);

pg.setVisibility(View.GONE);

mSimpleAdapter.notifyDataSetChanged();// 通知listView重新整理資料

}

}, 2000);

}

});

}

private void loadMoreDate() {

int count = mSimpleAdapter.getCount();

if (count + 5 < MaxDateNum) {

// 每次載入5條

for (int i = count; i < count + 5; i++) {

HashMap<String, String> map = new HashMap<String, String>();

map.put("ItemTitle", "新增第" + i + "行標題");

map.put("ItemText", "新增第" + i + "行內容");

list.add(map);
