以前做过，数据是在本地xml里面取的:上面是省市区的xml数据网盘地址。 如果要做成从服务器取，那么就一次性取下来，然后还是一样的流程。如果你想选择省再去取对应的市，那么就要传省的id去获取对应的市，这时候就要有等待框，可能用户体验差一点。

public class Area {
private String province;
private String city;
//省略属性区和get set方法
public boolean isSame(Area area){
if(!area.getProvince().equals(province)){
return false;
}
if(!area.getCity().equals(province)){
return false;
}
//省略 区
return true;//相同
}
}
Androidspinner实现省市二级联动，需要自定义adpter，将数据源绑定到adpter，当点击省时，触发自定义响应事件，改变市，示例如下:
public class MainActivity extends Activity {
private TextView textView ;
private Spinner province;
private Spinner city;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//String[] provinces = new String[]{"-省份-","河北省","山西省","北京"};
textView = (TextView)this.findViewById(R.id.textView);
province = (Spinner)this.findViewById(R.id.province);
city = (Spinner)this.findViewById(R.id.city);
//(处理省的显示)
//将可选内容与ArrayAdapter的连接(从资源数组文件中获取数据)
ArrayAdapterCharSequence adapter =
ArrayAdapter.createFromResource(this, R.array.province, android.R.layout.simple_spinner_item);
//new ArrayAdapterString(this,android.R.layout.simple_spinner_item, provinces);
//设置下拉列表的风格
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
//将数据绑定到Spinner视图上
province.setAdapter(adapter);
//添加条目被选中监听器
province.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView? parent, View view,int position, long id) {
//parent既是province对象
Spinner spinner = (Spinner)parent;
String pro = (String)spinner.getItemAtPosition(position);
//(处理省的市的显示)
//将默认值与ArrayAdapter连接(从资源数组文件中获取数据)
ArrayAdapterCharSequence cityAdapter = ArrayAdapter.createFromResource
(MainActivity.this, R.array.citydefault, android.R.layout.simple_spinner_item);
//new ArrayAdapterCharSequence
// (MainActivity.this,android.R.layout.simple_spinner_item, cities);
//获取所在省含有哪些市(从资源数组文件中获取数据)
if(pro.equals("河北省")){
cityAdapter = ArrayAdapter.createFromResource
(MainActivity.this, R.array.hb, android.R.layout.simple_spinner_item);
}else if(pro.equals("北京市")){
cityAdapter = ArrayAdapter.createFromResource
(MainActivity.this, R.array.bj, android.R.layout.simple_spinner_item);
}else if(pro.equals("山西省")){
cityAdapter = ArrayAdapter.createFromResource
(MainActivity.this, R.array.shx, android.R.layout.simple_spinner_item);
}
//绑定数据到Spinner(City)上
city.setAdapter(cityAdapter);
}
@Override
public void onNothingSelected(AdapterView? parent) {
}
});
}
}
