实现功能：解析Addresstable.xml,里面存放的是中国的省、市、县、镇，通过省、市查看对应的、县市，然后在查询下一级。
<China> <firstAddress AddressCode="1100000000" AddressName="北京" Addressdisabled="N"> <secondAddress AddressCode="1101000000" AddressName="市辖区" Addressdisabled="N"> <thirdAddress AddressCode="1101010000" AddressName="东城区1" Addressdisabled="N" /> <thirdAddress AddressCode="1101020000" AddressName="西城区" Addressdisabled="N" /> <thirdAddress AddressCode="1101030000" AddressName="崇文区" Addressdisabled="N" /> <thirdAddress AddressCode="1101040000" AddressName="宣武区" Addressdisabled="N" /> <thirdAddress AddressCode="1101050000" AddressName="朝阳区" Addressdisabled="N" /> <thirdAddress AddressCode="1101060000" AddressName="丰台区" Addressdisabled="N" /> <thirdAddress AddressCode="1101070000" AddressName="石景山区" Addressdisabled="Y" /> <thirdAddress AddressCode="1101080000" AddressName="海淀区" Addressdisabled="Y" /> <thirdAddress AddressCode="1101090000" AddressName="门头沟区" Addressdisabled="Y" /> <thirdAddress AddressCode="1101110000" AddressName="房山区" Addressdisabled="Y" /> <thirdAddress AddressCode="1101120000" AddressName="通州区" Addressdisabled="Y" /> <thirdAddress AddressCode="1101130000" AddressName="顺义区" Addressdisabled="Y" /> <thirdAddress AddressCode="1101140000" AddressName="昌平区" Addressdisabled="Y" /> <thirdAddress AddressCode="1101150000" AddressName="大兴区" Addressdisabled="Y" /> <thirdAddress AddressCode="1101160000" AddressName="怀柔区" Addressdisabled="Y" /> <thirdAddress AddressCode="1101170000" AddressName="平谷区" Addressdisabled="Y" /> </secondAddress> <secondAddress AddressCode="1102000000" AddressName="县" Addressdisabled="N"> <thirdAddress AddressCode="1102280000" AddressName="密云" Addressdisabled="N" /> <thirdAddress AddressCode="1102290000" AddressName="延庆县" Addressdisabled="N" /> </secondAddress> </firstAddress>
public void getChinaAddresssFromXml(Context context,String fileName) {
Node first = null;
Node second = null;
Node third = null;
try {
// 首先找到xml文件
factory = DocumentBuilderFactory.newInstance();
// 找到xml，并加载文档
builder = factory.newDocumentBuilder();
inputStream = context.getResources().getAssets().open(fileName);
document = builder.parse(inputStream);
// 找到根Element
Element root = document.getDocumentElement();
// firstAddress
NodeList nodelist = root.getChildNodes();
for (int i = 0; i < nodelist.getLength(); i++) {
first = nodelist.item(i);
// firstAddress
if (first.getNodeType() == Node.ELEMENT_NODE) {
if (first.getNodeName().equals("firstAddress")) {
NamednodeMap namednodemap = first.getAttributes();
String AddressCode = namednodemap.getNamedItem(
"AddressCode").getNodeValue();
String AddressName = namednodemap.getNamedItem(
"AddressName").getNodeValue();
String Addressdisabled = namednodemap.getNamedItem(
"Addressdisabled").getNodeValue();
province.add(new ChinaAddress(AddressCode,AddressName,Addressdisabled));
}
}
// secondAddress
for (second = first.getFirstChild(); second != null; second = second
.getNextSibling()) {

if (second.getNodeName().equals("secondAddress")) {
NamednodeMap namednodemap = second.getAttributes();
String AddressCode = namednodemap.getNamedItem(

String Addressdisabled = namednodemap.getNamedItem(

county.add(new ChinaAddress(AddressCode,Addressdisabled));
}
}
// thirdAddress
for (third = second.getFirstChild(); third != null; third = third

if (third.getNodeType() == Node.ELEMENT_NODE) {
if (third.getNodeName().equals("thirdAddress")) {
NamednodeMap namednodemap = third
.getAttributes();
String AddressCode = namednodemap.getNamedItem(

String AddressName = namednodemap.getNamedItem(

String Addressdisabled = namednodemap
.getNamedItem("Addressdisabled")
.getNodeValue();
town.add(new ChinaAddress(AddressCode,Addressdisabled));
}
}
}
}
}
} catch (IOException e) {
e.printstacktrace();
} catch (SAXException e) {
e.printstacktrace();
} catch (ParserConfigurationException e) {
e.printstacktrace();
} finally {
try {
inputStream.close();
} catch (IOException e) {
e.printstacktrace();
}
}
}
该XML文件里主要有三个标签firstAddress，secondAddress，thirdAddress，通过for循环调用getNo的Name()方法进行判断,然后调用getAttributes()获取属性，接着再调用getNamedItem("AddressCode").getNodeValue()获取对应属性名的值即可。
使用ListView展示部分，具体看代码，并不难。主要是解析XML获取到想要的值填充到
private ArrayList<ChinaAddress> province = new ArrayList<ChinaAddress>();
private ArrayList<ChinaAddress> county = new ArrayList<ChinaAddress>();
private ArrayList<ChinaAddress> town = new ArrayList<ChinaAddress>();
然后再映射到对应的ListView即可，关键部分是就是ListView的监听，获取对应项的AddressCode，并用于判断下一个ListView应该填充哪些内容。
listview.setonItemClickListener(new OnItemClickListener() { @SuppressWarnings("unchecked") @Override public void onItemClick(AdapterView<?> parent,View view,int position,long id) { HashMap<String,Object> map = (HashMap<String,Object>) parent .getItemAtPosition(position); String name = (String) map.get("AddressName"); AddressCode = (String) map.get("AddressCode"); String keyCode = AddressCode.substring(0,2); // Toast.makeText(MainActivity.this,name + keyCode,0).show(); HashMap<String,Object> countymap; ChinaAddress c; countyDataList.clear(); for (int i = 0; i < county.size(); i++) { c = new ChinaAddress(); c = county.get(i); // 根据代码获取选区省市对应的县、镇 if (c.getAddressCode().substring(0,2).equals(keyCode)) { countymap = new HashMap<String,Object>(); countymap.put("AddressName",c.getAddressName()); countymap.put("AddressCode",c.getAddressCode()); countymap.put("Addressdisabled",c.getAddressdisabled()); countyDataList.add(countymap); } } // 设置countyDataList共享 ((MyAppData) getApplication()) .setCountyDataList(countyDataList); Intent intent = new Intent(); intent.putExtra("TITLE",name); intent.setClass(MainActivity.this,CountyActivity.class); startActivity(intent); } });
基本上差不多，代码很简单，下载源代码自己查看即可。对了，搜素功能暂未实现，有兴趣可以自己试试。
