通过WheelView来实现省市县三级联动
首先要创建三个实体类：
provinceInfo，cityInfo，districtInfo
准备开始写！！！
//此处调用
case R.id.edit_address_choose:
chooseAddress();//选择地址
break;
弹出地址选择框
//选择地址
private PopWindowLoader popWindowLoader;
private WheelView address_province;
private WheelView address_city;
private WheelView address_county;
private TextView address_cancel,address_sure;
public void chooseAddress(){
popWindowLoader = new PopWindowLoader(this,R.layout.addr_picker);
popWindowLoader.init(this, ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.WRAP_CONTENT,0xffffff);
popWindowLoader.setAnimationStyle(R.style.share_show_miss_Animation);
address_province = popWindowLoader.findViewById(R.id.address_province);
address_city = popWindowLoader.findViewById(R.id.address_city);
address_county = popWindowLoader.findViewById(R.id.address_county);
address_cancel = popWindowLoader.findViewById(R.id.address_cancel);
address_sure = popWindowLoader.findViewById(R.id.address_sure);
//省
address_province.setOnSelectListener(new WheelView.OnSelectListener() {
@Override
public void endSelect(int id, String text) {
String provinceText = mProvinceDatas.get(id);
if (!mCurrentProviceName.equals(provinceText)){
mCurrentProviceName = provinceText;
ArrayList<String> mCityData = mCitisDatasMap.get(mCurrentProviceName);
address_city.resetData(mCityData);//重置市数据集合
address_city.setDefault(0);
mCurrentCityName = mCityData.get(0);
ArrayList<String> mDistrictData = mDistrictDatasMap.get(mCurrentCityName);
address_county.resetData(mDistrictData);//重置县数据集合
address_county.setDefault(0);

}
}
@Override

}
});
address_city.setOnSelectListener(new WheelView.OnSelectListener() {

mCurrentDistrictName = mCountyData.get(0);
}
}
@Override

});
address_cancel.setOnClickListener(new View.OnClickListener() {
@Override

popWindowLoader.dismiss();
}
});
address_sure.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String addr = mCurrentProviceName + mCurrentCityName;
if (!mCurrentDistrictName.equals("其他")) {
addr += mCurrentDistrictName;
}
edit_address_choose_message.setText(addr);
popWindowLoader.dismiss();
}
});
//设置默认数据
new Thread() {
@Override
public void run() {
isDataLoaded = readAddrData();
Log.d(TAG, "isDataLoaded: " +isDataLoaded);
// 通知界面线程
new Handler(Looper.getMainLooper()).post(new Runnable() {

}
});
}
}.start();
if (isDataLoaded){
popWindowLoader.showAtLocation(AddressManagerActivity.this, Gravity.CENTER | Gravity.BOTTOM, 0, 0);
}else {
ToastUtil.showToast2(this,"正在加载！");
}
}
//读取数据
private boolean readAddrData(){
List<ProvinceInfo> provinceInfoList ;
AssetManager asset = getAssets();
try {

return true;

创建解析的类AddrXmlParser
public class AddrXmlParser extends DefaultHandler {
private List<ProvinceInfo> provinceList = new ArrayList<>();
public List<ProvinceInfo> getList(){
return provinceList;
}
private ProvinceInfo provinceInfo = new ProvinceInfo();
private CityInfo cityInfo = new CityInfo();
private DistrictInfo districtInfo = new DistrictInfo();
@Override
public void startDocument() throws SAXException {
super.startDocument();
}
@Override
public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {
super.startElement(uri, localName, qName, attributes);
if (qName.equals("province")){
provinceInfo = new ProvinceInfo();
provinceInfo.setName(attributes.getValue(0));
provinceInfo.setCityList(new ArrayList<CityInfo>());
}else if (qName.equals("city")){
cityInfo = new CityInfo();
cityInfo.setName(attributes.getValue(0));
cityInfo.setDistrictInfo(new ArrayList<DistrictInfo>());
}else if (qName.equals("district")){
districtInfo = new DistrictInfo();
districtInfo.setName(attributes.getValue(0));
districtInfo.setZipcode(attributes.getType(1));
}
}
@Override
public void endElement(String uri, String localName, String qName) throws SAXException {
super.endElement(uri, localName, qName);
if (qName.equals("district")){
cityInfo.getDistrictInfo().add(districtInfo);
}else if (qName.equals("city")){
provinceInfo.getCityList().add(cityInfo);
}else if (qName.equals("province")){
provinceList.add(provinceInfo);
}
}
@Override
public void characters(char[] ch, int start, int length) throws SAXException {
super.characters(ch, start, length);
}
}
