城市列表-根據拼音首字母排序

今天我們就簡單的實現一下城市的排序 讀取我們城市的資訊並通過listview展示 首先看一下我們的佈局檔案

<LinearLayout 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:orientation="vertical"
    >
<FrameLayout android:layout_width="fill_parent" android:layout_height="fill_parent" > <ListView android:id="@+id/lv" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_gravity
="center" android:divider="@null" >
</ListView> </FrameLayout> </LinearLayout>

我們看到佈局檔案中就是一個展示列表的listView
下面看一下我們需要展示的城市的列表資訊 在values資料夾下面建立一個xml檔名稱叫做 arrays.xml

<?xml version="1.0" encoding="UTF-8"?>
<resources>

    <string-array name
="date">
<item>北京首都</item> <item>上海虹橋</item> <item>上海浦東</item> <item>廣州</item> <item>深圳</item> <item>香港</item> <item>澳門</item> <item>天津</item> <item>成都</item> <item>重慶</item> <item>南京</item> <item>青島</item> <item>珠海</item> <item>福州</item> <item>哈爾濱</item> <item>大連</item> <item>海口</item> <item>瀋陽</item> <item>廈門</item> <item>安慶</item> <item>鞍山</item> <item>阿克蘇</item> <item>阿勒泰</item> <item>安康</item> <item>北京首都</item> <item>北京南苑</item> <item>保山</item> <item>包頭</item> <item>北海</item> <item>蚌埠</item> <item>重慶</item> <item>成都</item> <item>長沙</item> <item>長春</item> <item>常德</item> <item>長治</item> <item>常州</item> <item>朝陽</item> <item>赤峰</item> <item>大連</item> <item>敦煌</item> <item>大理</item> <item>達縣</item> <item>東營</item> <item>丹東</item> <item>大同</item> <item>恩施</item> <item>福州</item> <item>阜陽</item> <item>富蘊</item> <item>廣州</item> <item>桂林</item> <item>貴陽</item> <item>格爾木</item> <item>廣漢</item> <item>贛州</item> <item>海口</item> <item>哈爾濱</item> <item>杭州</item> <item>合肥</item> <item>黃山</item> <item>呼和浩特</item> <item>海拉爾</item> <item>哈密</item> <item>漢中</item> <item>黑河</item> <item>衡陽</item> <item>和田</item> <item>黃岩</item> <item>吉林</item> <item>濟南</item> <item>九江</item> <item>九寨黃龍</item> <item>吉安</item> <item>佳木斯</item> <item>嘉峪關</item> <item>濟寧</item> <item>景德鎮</item> <item>景洪</item> <item>晉江</item> <item>錦州</item> <item>酒泉</item> <item>昆明</item> <item>克拉瑪依</item> <item>喀什</item> <item>庫爾勒</item> <item>庫車</item> <item>洛陽</item> <item>蘭州</item> <item>拉薩</item> <item>連雲港</item> <item>麗江</item> <item>臨沂</item> <item>柳州</item> <item>瀘州</item> <item>芒市</item> <item>梅縣</item> <item>綿陽</item> <item>牡丹江</item> <item>滿洲里</item> <item>南京</item> <item>寧波</item> <item>南昌</item> <item>南寧</item> <item>南通</item> <item>南充</item> <item>南陽</item> <item>青島</item> <item>秦皇島</item> <item>齊齊哈爾</item> <item>泉州</item> <item>衢州</item> <item>且末</item> <item>慶陽</item> <item>瀋陽</item> <item>深圳</item> <item>上海虹橋</item> <item>上海浦東</item> <item>汕頭</item> <item>石家莊</item> <item>蘇州</item> <item>三亞</item> <item>沙市</item> <item>思茅</item> <item>天津</item> <item>塔城</item> <item>太原</item> <item>通化</item> <item>通遼</item> <item>銅仁</item> <item>溫州</item> <item>武漢</item> <item>武漢王家</item> <item>無錫</item> <item>烏魯木齊</item> <item>威海</item> <item>梧州</item> <item>萬縣</item> <item>濰坊</item> <item>烏蘭浩特</item> <item>武夷山</item> <item>廈門</item> <item>徐州</item> <item>西安</item> <item>西寧</item> <item>西昌</item> <item>襄樊</item> <item>錫林浩特</item> <item>銀川</item> <item>延安</item> <item>延吉</item> <item>煙臺</item> <item>鹽城</item> <item>宜賓</item> <item>宜昌</item> <item>伊寧</item> <item>義烏</item> <item>永州</item> <item>榆林</item> <item>珠海</item> <item>昭通</item> <item>張家界</item> <item>湛江</item> <item>芷江</item> <item>中甸</item> <item>舟山</item> <item>遵義</item> <item>鄭州</item> </string-array> </resources>

下面我們就對這個資料進行一系列化的操作

首先就是讀取我們的城市列表

import java.util.ArrayList;
import java.util.List;

public class getCityList {
    private CharacterParser characterParser;
    public getCityList(CharacterParser characterParser) {
        super();
        this.characterParser = characterParser;
    }
    /**
     * 為ListView填充資料
     * 
     * @param date
     * @return
     */
    public List<CityData> filledData(String[] date) {
        List<CityData> mSortList = new ArrayList<CityData>();

        for (int i = 0; i < date.length; i++) {
            CityData cityData = new CityData();
            cityData.setName(date[i]);
            // 漢字轉換成拼音
            String pinyin = characterParser.getSelling(date[i]);
            String sortString = pinyin.substring(0, 1).toUpperCase();

            // 正則表示式,判斷首字母是否是英文字母
            if (sortString.matches("[A-Z]")) {
                cityData.setFristA(sortString.toUpperCase());
            } else {
                cityData.setFristA("#");
            }
            mSortList.add(cityData);
        }
        return mSortList;
    }
}

讀取完成之後我們需要在主方法中實現呼叫
下面看一下我們主類中的實現程式碼

import java.util.Collections;
import java.util.List;
import android.app.Activity;
import android.os.Bundle;
import android.widget.ListView;

public class MainActivity extends Activity {
    private ListView lv;//列表的控制元件
    private MyCityAdapter adapter;//介面卡
    private List<CityData> citylist;//列表集合
    /**
     * 漢字轉換成拼音的類
     */
    private CharacterParser characterParser;
    /**
     * 根據拼音來排列ListView裡面的資料類
     */
    private PinyinComparator pinyinComparator;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        initData();
    }

    private void initData() {
        // 繫結控制元件
        lv = (ListView) findViewById(R.id.lv);
        // 例項化漢字轉拼音類
        characterParser = CharacterParser.getInstance();
        pinyinComparator = new PinyinComparator();
        getCity();

    }
    /**
     * 獲得城市列表並新增到介面卡
     */
    private void getCity() {
        // 獲取城市的資訊
        getCityList cityList = new getCityList(characterParser);
        // 獲得城市的資料列表
        citylist = cityList.filledData(getResources().getStringArray(
                R.array.date));
        // 根據a-z進行排序源資料
        Collections.sort(citylist, pinyinComparator);
        adapter = new MyCityAdapter(MainActivity.this, citylist);
        lv.setAdapter(adapter);
    }
}

在主類中我們看到 我們將讀取的城市漢字首先轉換為拼音

/**
 * Java漢字轉換為拼音
 *
