android在代码中利用Spinner控件设置联动地区的解决办法
需求就是地区选择可以弹出来，因为百度地图一般是获取当前的地址，我们需要的是他的家庭地址 所以才有了三级Spinner解决
地区问题 就是当用户填写了之后，下次再修改，你要给他显示出来上次填写的值，由于是联动的比较麻烦
首先是要搞定地区的问题，一般是用array来设置 这里面我只贴一部分
<!-- 含个省、自治区、直辖市 -->
<string-array name="province_item">
<item>不限地区</item>
<item>北京</item>
<item>天津</item>
<item>河北</item>
<item>山西</item>
<item>内蒙古</item>
<item>辽宁</item>
<item>吉林</item>
<item>黑龙江</item>
<item>上海</item>
<item>江苏</item>
<item>浙江</item>
<item>安徽</item>
<item>福建</item>
<item>江西</item>
<item>山东</item>
<item>河南</item>
<item>湖北</item>
<item>湖南</item>
<item>广东</item>
<item>广西</item>
<item>海南</item>
<item>重庆</item>
<item>四川</item>
<item>贵州</item>
<item>云南</item>
<item>西藏</item>
<item>陕西</item>
<item>甘肃</item>
<item>青海</item>
<item>宁夏</item>
<item>新疆</item>
</string-array>
<!-- 个地级市 -->
<string-array name="unlimited_province_item">
<item>不限地区</item>
</string-array>
<string-array name="beijin_province_item">
<item>北京</item>
</string-array>
<string-array name="tianjin_province_item">
<item>天津</item>
</string-array>
<string-array name="heibei_province_item">
<item>石家庄</item>
<item>唐山</item>
<item>秦皇岛</item>
<item>邯郸</item>
<item>邢台</item>
<item>保定</item>
<item>张家口</item>
<item>承德</item>然后把这个东西搞成一个类来装
public class ResourceData {
public static final int[] city = { R.array.beijin_province_item, R.array.tianjin_province_item, R.array.heibei_province_item,
R.array.shanxi1_province_item, R.array.neimenggu_province_item, R.array.liaoning_province_item,
R.array.jilin_province_item, R.array.heilongjiang_province_item, R.array.shanghai_province_item,
R.array.jiangsu_province_item, R.array.zhejiang_province_item, R.array.anhui_province_item,
R.array.fujian_province_item, R.array.jiangxi_province_item, R.array.shandong_province_item,
R.array.henan_province_item, R.array.hubei_province_item, R.array.hunan_province_item,
R.array.guangdong_province_item, R.array.guangxi_province_item, R.array.hainan_province_item,
R.array.chongqing_province_item, R.array.sichuan_province_item, R.array.guizhou_province_item,
R.array.yunnan_province_item, R.array.xizang_province_item, R.array.shanxi2_province_item,
R.array.gansu_province_item, R.array.qinghai_province_item, R.array.linxia_province_item,
R.array.xinjiang_province_item };
}这里面只写一部分了 多个地级市，县城你自己加吧
接下来就是代码中搞定了：
要准备一个函数：
private void select(Spinner spin, ArrayAdapter<CharSequence> adapter, int arry,int position) {
adapter = ArrayAdapter.createFromResource(context, arry, R.drawable.drop_list_hover);
adapter.setDropDownViewResource(R.drawable.drop_list_ys);
spin.setAdapter(adapter);
spin.setSelection(position, true);
}这个函数的功能就是给一个 Spinner进行初始化把，参数分别是Spinner对象，适配器，数据集，默认位置
因为在设置联动的时候都是根据上一个Spinner选择的值 id来决定下一个Spinner的值
接下来就先贴代码了
private void loadAddsSpinner() {
province_spinner = (Spinner) findViewById(R.id.province_spinner);
province_spinner.setPrompt("请选择省份");
province_adapter = ArrayAdapter.createFromResource(context, R.array.province_item,
R.drawable.drop_list_hover);
province_adapter.setDropDownViewResource(R.drawable.drop_list_ys);
province_spinner.setAdapter(province_adapter);
province_spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
provinceId = province_spinner.getSelectedItemPosition();
strProvince = province_spinner.getSelectedItem().toString();
city_spinner = (Spinner) findViewById(R.id.city_spinner);
if (true) {
Log.v("test", "province: " + province_spinner.getSelectedItem().toString() + provinceId.toString());
county_spinner = (Spinner) findViewById(R.id.county_spinner);
city_spinner = (Spinner) findViewById(R.id.city_spinner);
city_spinner.setPrompt("请选择城市");
select(city_spinner, city_adapter, ResourceData.city[provinceId],sposition);
city_spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
cityId = city_spinner.getSelectedItemPosition();
strCity = city_spinner.getSelectedItem().toString();
Log.v("test", "city: " + city_spinner.getSelectedItem().toString() + cityId.toString());
if (true) {
county_spinner = (Spinner) findViewById(R.id.county_spinner);
county_spinner.setPrompt("请选择县区");
switch (provinceId) {

public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
strCounty = county_spinner.getSelectedItem().toString();
if (strProvince.equals(strCity)) {
xiangxiadd.setText(strProvince + strCounty);
region = strProvince + "," + strCounty;
xiangxiaddress = region +","+xiangxiaddress;//详细地址加上前缀
} else {
xiangxiadd.setText(strProvince + strCity + strCounty);
region = strProvince + "," + strCity + "," + strCounty;
xiangxiaddress = region +","+xiangxiaddress;//详细地址加上前缀
}
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
}
});
}
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
}
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
}
});
}这里面最重要的就是select代码了 注意最后一个参数的作用 position 他就是用来设置默认值的
后面就简单了，分析从服务器中返回的数据，判断是哪个id 变成position就好了
我的是这样做的，可能还有人更坚定，我感觉我的稍显负责
//省市县
String ssxStr = element.optString("ind_origin2");
if(ssxStr!=null || ssxStr !="" || ssxStr!="null"){
String[] ss = ssxStr.split(",");
Log.i("Wusheng", ss.length+"-----322125");
if(ss.length == 2){
province_spinner.setSelection(initProSpinner(ss[0]), true);
int proInt = initProSpinner(ss[0]);
int cityInt = initCitySpinner(proInt,ss[0]);
sposition = cityInt;
provinceId = proInt;
cityId = cityInt;
int xianInt = initCountSpinner(proInt,sposition,ss[1]);
xianposition = xianInt;
//Log.i("Wusheng",ResourceData.city[initProSpinner(ss[0])]);
}else if(ss.length == 3){
Log.i("Wusheng", initProSpinner(ss[0])+"322125");
province_spinner.setSelection(initProSpinner(ss[0]), true);
int proInt = initProSpinner(ss[0]);
int cityInt = initCitySpinner(proInt,ss[1]);
sposition = cityInt;
provinceId = proInt;
cityId = cityInt;
//接下来通过省，市的代码去找到县的代码
int xianInt = initCountSpinner(proInt,sposition,ss[2]);
Log.i("Wusheng",xianInt+"-----44---322125");
xianposition = xianInt;
}
}这里面是异步进程handler里面的处理省 市县的代码 为什么切分之后分为两种呢，因为我们有北京 重庆这样的特殊省份
根据省的名称返回省的代码：
/**
* 根据省名称返回 下标值
* @param proStr
* @return
*/
public int initProSpinner(String proStr){
String[] pros=this.getResources().getStringArray(R.array.province_item);
for(int i=0;i<pros.length;i++){
if(proStr.equals(pros[i])){
return i;
}
}
return 0;
}看客不要太在意我定义了那么多int变量啊，因为怕写错了，所以分的比较清楚，后面的很多int都去掉了，
/**
* 根据省代码 来获取 市的代码
* @param proInt
* @param string
* @return
*/
public int initCitySpinner(int proInt, String citStr) {
// TODO Auto-generated method stub
String[] citys=this.getResources().getStringArray(ResourceData.city[proInt]);
for(int i=0;i<citys.length;i++){
if(citStr.equals(citys[i])){
return i;
}
}
return 0;
}根据省代码去获取 市的代码，你可能会认为，为什么上面不根据名称直接去获取市的代码，那你想多了，你可以看看我的根据array构造数组的时候怎么调用id值的
/**
* 根据省 市代码 来获取 县的代码
* @param sposition2
* @param string
* @return
*/
public int initCountSpinner(int proint,int sposition2, String countStr) {
// TODO Auto-generated method stub
String[] citys= null;
switch (proint) {
case 0:
citys = this.getResources().getStringArray(ResourceData.countyOfBeiJing[sposition2]);
break;
case 1:
citys = this.getResources().getStringArray(ResourceData.countyOfTianJing[sposition2]);
break;
case 2:
citys = this.getResources().getStringArray(ResourceData.countyOfHeBei[sposition2]);

default:
break;
}
for(int i=0;i<citys.length;i++){
if(countStr.equals(citys[i])){
return i;
}
}
return 0;
}这个地方就稍微县的臃肿了，那位看客又更好的方法没有，中国低级县区太多了，至少有2800个左右吧，我也想不出来怎么用代码更好的找到每个县的代码
到此基本就完成了认为，运行下就解决了问题
其中解析那里用的是 当前类的私有变量 不用多说了
