在我上传的资源中有[SQLLite版全国省市区的数据库][SQLLite]，现在我来介绍下我开发地址列表时获取省市区数据时的方法。

废话少说，代码如下所示：

package xxxx.com.common;  
  
import java.io.File;  
import java.util.ArrayList;  
import java.util.HashMap;  
import java.util.List;  
import java.util.Map;  
  
import android.database.Cursor;  
import android.database.sqlite.SQLiteDatabase;  
import android.util.Log;  
  
public class AddressUtil \{  
  
    //获取省的地址列表,//file-->数据库文件  
    public static Map<Integer,List> getProvince(File file)\{  
          
        String sql = "select ProSort ,ProName from T\_Province ";  
        SQLiteDatabase db = null;  
        Cursor c = null;  
        Map<Integer,List> provinceData = new HashMap<Integer,List>();  
        //List provinceList = null;  
        try\{  
                db = SQLiteDatabase.openOrCreateDatabase(file, null);  
                c = db.rawQuery(sql, null);  
                List provinceList1 = new ArrayList();  
                List provinceList2 = new ArrayList();  
                while(c.moveToNext())\{  
                        Map provinceMap = new HashMap();  
                        provinceMap.put(c.getString(1), c.getInt(0));  
                        provinceList1.add(provinceMap);  
                        provinceList2.add(c.getString(1));  
                \}  
                provinceData.put(0, provinceList1);  
                provinceData.put(1, provinceList2);  
        \}catch(Exception e)\{  
                Log.d("WineStock", "getProvince:"+e.getMessage());  
        \}finally\{  
                if(c!=null)\{  
                        c.close();  
                \}  
                if(db!=null)\{  
                        db.close();  
                \}  
        \}  
        return provinceData;  
    \}  
    //获取对应省下面城市的列表,//file-->数据库文件,id-->指对应省的ID  
    public static Map<Integer,List> getCityByPid(int id,File file)\{  
        String sql = "select ProID,CityName  from T\_City where ProID= "+id;  
        SQLiteDatabase db = null;  
        Cursor c = null;  
        Map<Integer,List> cityData = new HashMap<Integer,List>();  
        //List cityList = null;  
        try\{  
                db = SQLiteDatabase.openOrCreateDatabase(file, null);  
                c = db.rawQuery(sql, null);  
                List cityList1 = new ArrayList();  
                List cityList2 = new ArrayList();  
                while(c.moveToNext())\{  
                        Map cityMap = new HashMap();  
                        cityMap.put(c.getString(1), c.getInt(0));  
                        cityList1.add(cityMap);  
                        cityList2.add(c.getString(1));  
                \}  
                cityData.put(0, cityList1);  
                cityData.put(1, cityList2);  
                  
        \}catch(Exception e)\{  
            Log.d("WineStock", "getCityByPid:"+e.getMessage());  
        \}finally\{  
                if(c!=null)\{  
                        c.close();  
                \}  
                if(db!=null)\{  
                        db.close();  
                \}  
        \}  
        return cityData;  
    \}  
    //获取对应市下面区的列表,//file-->数据库文件,id-->指对应市的ID  
    public static List<String> getAreaByPid(int id,File file)\{  
        String sql = "select ZoneName  from T\_Zone where CityID= "+id;  
        SQLiteDatabase db = null;  
        Cursor c = null;  
        List<String> areaList = null;  
        try\{  
                db = SQLiteDatabase.openOrCreateDatabase(file, null);  
                c = db.rawQuery(sql, null);  
                areaList = new ArrayList<String>();  
                while(c.moveToNext())\{  
                    areaList.add(c.getString(0));  
                \}  
        \}catch(Exception e)\{  
            Log.d("WineStock", "getAreaByPid:"+e.getMessage());  
        \}finally\{  
                if(c!=null)\{  
                        c.close();  
                \}  
                if(db!=null)\{  
                        db.close();  
                \}  
        \}  
        return areaList;  
    \}  
      
\}
