Android 获取全国城市列表类似于联系人排序

  

           相信很多人都有看过或了解过城市列表和联系人排序这种效果，下面来直接看看我今天要实现的效果：

可以进行城市的搜索，效果很实用，直接上代码：源码下载 点击下载源码

1.主函数：

import java.util.ArrayList;import java.util.List;import android.app.Activity;import android.content.Context;import android.os.AsyncTask;import android.os.Bundle;import android.text.Editable;import android.text.TextWatcher;import android.util.Log;import android.view.View;import android.widget.AdapterView;import android.widget.EditText;import android.widget.Toast;import com.liucanwen.citylist.adapter.CityAdapter;import com.liucanwen.citylist.data.CityData;import com.liucanwen.citylist.model.CityItem;import com.liucanwen.citylist.widget.ContactItemInterface;import com.liucanwen.citylist.widget.ContactListViewImpl;public class CityListActivity extends Activity implements TextWatcher{private Context context_ = CityListActivity.this;private ContactListViewImpl listview;private EditText searchBox;private String searchString;private Object searchLock = new Object();boolean inSearchMode = false;private final static String TAG = "MainActivity2";List<ContactItemInterface> contactList;List<ContactItemInterface> filterList;private SearchListTask curSearchTask = null;@Overridepublic void onCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState);setContentView(R.layout.citylist);filterList = new ArrayList<ContactItemInterface>();contactList = CityData.getSampleContactList();CityAdapter adapter = new CityAdapter(this,R.layout.city_item, contactList);listview = (ContactListViewImpl) this.findViewById(R.id.listview);listview.setFastScrollEnabled(true);listview.setAdapter(adapter);listview.setOnItemClickListener(new AdapterView.OnItemClickListener(){@Overridepublic void onItemClick(AdapterView parent, View v, int position,long id){List<ContactItemInterface> searchList = inSearchMode ? filterList: contactList;Toast.makeText(context_,searchList.get(position).getDisplayInfo()+"9",Toast.LENGTH_SHORT).show();}});searchBox = (EditText) findViewById(R.id.input_search_query);searchBox.addTextChangedListener(this);}@Overridepublic void afterTextChanged(Editable s){searchString = searchBox.getText().toString().trim().toUpperCase();if (curSearchTask != null&& curSearchTask.getStatus() != AsyncTask.Status.FINISHED){try{curSearchTask.cancel(true);} catch (Exception e){Log.i(TAG, "Fail to cancel running search task");}}curSearchTask = new SearchListTask();curSearchTask.execute(searchString); }@Overridepublic void beforeTextChanged(CharSequence s, int start, int count,int after){}@Overridepublic void onTextChanged(CharSequence s, int start, int before, int count){// do nothing}private class SearchListTask extends AsyncTask<String, Void, String>{@Overrideprotected String doInBackground(String... params){filterList.clear();String keyword = params[0];inSearchMode = (keyword.length() > 0);if (inSearchMode){// get all the items matching thisfor (ContactItemInterface item : contactList){CityItem contact = (CityItem) item;boolean isPinyin = contact.getFullName().toUpperCase().indexOf(keyword) > -1;boolean isChinese = contact.getNickName().indexOf(keyword) > -1;if (isPinyin || isChinese){filterList.add(item);}}}return null;}protected void onPostExecute(String result){synchronized (searchLock){if (inSearchMode){CityAdapter adapter = new CityAdapter(context_,R.layout.city_item, filterList);adapter.setInSearchMode(true);listview.setInSearchMode(true);listview.setAdapter(adapter);} else{CityAdapter adapter = new CityAdapter(context_,R.layout.city_item, contactList);adapter.setInSearchMode(false);listview.setInSearchMode(false);listview.setAdapter(adapter);}}}}

2.适配器：

import java.util.List;import android.content.Context;import android.view.View;import android.widget.TextView;import com.liucanwen.citylist.R;import com.liucanwen.citylist.widget.ContactItemInterface;import com.liucanwen.citylist.widget.ContactListAdapter;public class CityAdapter extends ContactListAdapter{public CityAdapter(Context _context, int _resource,List<ContactItemInterface> _items){super(_context, _resource, _items);}public void populateDataForRow(View parentView, ContactItemInterface item,int position){View infoView = parentView.findViewById(R.id.infoRowContainer);TextView nicknameView = (TextView) infoView.findViewById(R.id.cityName);nicknameView.setText(item.getDisplayInfo());}}

3.CityData类

import android.content.Context;import android.database.Cursor;import android.database.sqlite.SQLiteDatabase;import java.io.FileOutputStream;import java.io.IOException;import java.io.InputStream;import java.util.ArrayList;import java.util.List;import org.json.JSONArray;import org.json.JSONException;import org.json.JSONObject;import com.liucanwen.citylist.model.CityItem;import com.liucanwen.citylist.widget.ContactItemInterface;import com.liucanwen.citylist.widget.pinyin.PinYin;/** *  * @author sgf *  */public class CityData{static String cityJson = "{'cities':['#','#热门城市','上海','北京','杭州','广州','南京','苏州','深圳','成都','重庆','天津','宁波','扬州','无锡','福州','厦门','武汉','西安','沈阳','大连','青岛','济南','海口','石家庄','唐山','秦皇岛','邯郸','邢台','保定','张家口','承德','沧州','廊坊','衡水','太原','大同','阳泉','长治','晋城','朔州','晋中','运城','忻州','临汾','吕梁','呼和浩特','包头','乌海','赤峰','通辽','鄂尔多斯','呼伦贝尔','兴安盟','锡林郭勒','乌兰察布','巴彦淖尔','阿拉善','鞍山','抚顺','本溪','丹东','锦州','营口','阜新','辽阳','盘锦','铁岭','朝阳','葫芦岛','长春','吉林','四平','辽源','通化','白山','松原','白城','延边','哈尔滨','齐齐哈尔','鸡西','鹤岗','双鸭山','大庆','伊春','佳木斯','七台河','牡丹江','黑河','绥化','大兴安岭','徐州','常州','南通','连云港','淮安','盐城','镇江','泰州','宿迁','温州','嘉兴','湖州','绍兴','金华','衢州','舟山','台州','丽水','合肥','芜湖','蚌埠','淮南','马鞍山','淮北','铜陵','安庆','黄山','滁州','阜阳','宿州','六安','亳州','池州','宣城','莆田','三明','泉州','漳州','南平','龙岩','宁德','南昌','景德镇','萍乡','九江','新余','鹰潭','赣州','吉安','宜春','抚州','上饶','淄博','枣庄','东营','烟台','潍坊','济宁','泰安','威海','日照','莱芜','临沂','德州','聊城','滨州','菏泽','郑州','开封','洛阳','平顶山','安阳','鹤壁','新乡','焦作','濮阳','许昌','漯河','三门峡','南阳','商丘','信阳','周口','驻马店','黄石','十堰','宜昌','襄阳','鄂州','荆门','孝感','荆州','黄冈','咸宁','随州','恩施州','仙桃','潜江','天门','株洲','湘潭','衡阳','邵阳','岳阳','常德','张家界','益阳','郴州','永州','怀化','娄底','湘西','韶关','珠海','汕头','佛山','江门','湛江','茂名','肇庆','惠州','梅州','汕尾','河源','阳江','清远','东莞','中山','潮州','揭阳','云浮','南宁','柳州','桂林','梧州','北海','防城港','钦州','贵港','玉林','百色','贺州','河池','自贡','攀枝花','泸州','德阳','绵阳','广元','遂宁','内江','乐山','南充','眉山','宜宾','广安','达州','雅安','巴中','资阳','阿坝','甘孜州','凉山','贵阳','六盘水','遵义','安顺','铜仁地区','黔西南','毕节地区','黔东南','黔南','昆明','曲靖','玉溪','保山','昭通','楚雄州','红河','文山州','普洱','西双版纳','大理州','德宏','丽江','怒江','迪庆','临沧','拉萨','昌都地区','山南','日喀则地区','那曲','阿里','林芝地区','铜川','宝鸡','咸阳','渭南','延安','汉中','榆林','安康','商洛','兰州','嘉峪关','金昌','白银','天水','武威','张掖','平凉','酒泉','庆阳','定西','陇南','临夏州','甘南','西宁','海东','海北','黄南','果洛','玉树','海西','银川','石嘴山','吴忠','固原','乌鲁木齐','克拉玛依','吐鲁番地区','哈密地区','昌吉州','博尔塔拉','巴音郭楞','阿克苏地区','克孜勒苏','喀什地区','和田地区','伊犁','塔城地区','阿勒泰地区','石河子','香港','澳门','长沙','三亚','中卫','儋州','保亭','昌江','澄迈县','崇左','定安县','东方','济源','来宾','乐东','陵水','琼海','神农架林区','图木舒克','屯昌县','万宁','文昌','海南州']}";public static List<ContactItemInterface> getSampleContactList(){List<ContactItemInterface> list = new ArrayList<ContactItemInterface>();try{JSONObject jo1 = new JSONObject(cityJson);JSONArray ja1 = jo1.getJSONArray("cities");for(int i = 0; i < ja1.length(); i++){String cityName = ja1.getString(i);list.add(new CityItem(cityName, PinYin.getPinYin(cityName)));}} catch (JSONException e){e.printStackTrace();}return list;}}

4.CityItem

import com.liucanwen.citylist.widget.ContactItemInterface;public class CityItem implements ContactItemInterface{private String nickName;private String fullName;public CityItem(String nickName, String fullName){super();this.nickName = nickName;this.setFullName(fullName);}@Overridepublic String getItemForIndex(){return fullName;}@Overridepublic String getDisplayInfo(){return nickName;}public String getNickName(){return nickName;}public void setNickName(String nickName){this.nickName = nickName;}public String getFullName(){return fullName;}public void setFullName(String fullName){this.fullName = fullName;}}

5.还有不少辅助类我就粘贴出来了，我提供了源码，亲可以直接下载，下面看看布局：city_item.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" >    <TextView        android:id="@+id/sectionTextView"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:layout_marginBottom="3dip"        android:background="#496491"        android:paddingLeft="8dip"        android:text="A"        android:textColor="#ffffff"        android:textSize="18sp"        android:textStyle="bold"        android:visibility="gone" />    <RelativeLayout        android:id="@+id/infoRowContainer"        android:layout_width="fill_parent"        android:layout_height="50dip"        android:background="@drawable/listitem_selector"        android:gravity="center_vertical"        android:paddingLeft="10dip" >        <TextView            android:id="@+id/cityName"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_alignParentTop="true"            android:text="广州"            android:textSize="20dip"            android:textStyle="bold" />    </RelativeLayout></LinearLayout>
