Android 如何解析本地xml文件以获取国家/地区详细信息？

我必须解析xml文件以获得国家详细信息，如国家名称和国家邮政编码。 如何将国家名称解析为微调器适配器，当我使用微调器选择特定国家时，我必须在textview中显示特定的国家代码

请帮帮我

提前感谢。

这里有一个解析Xml文件的代码，您必须在其中传递本地Xml文件的inputstream。

public static ArrayList<Country> parseCountry(Context context, InputStream inputStream) {
    String KEY = "";
    String VALUE = null;
    ArrayList<Country> arrCountires = new ArrayList<Country>();
    Country country = null;
    ArrayList<State> arrStates = null;
    State state= null;
    ArrayList<City> arrCities = null;
    City city = null;

    try {
        InputStreamReader inputreader = null;
        if(inputStream != null) {
            inputreader = new InputStreamReader(inputStream);
        }

        if(inputreader != null) {
            XmlPullParserFactory factory = null;
            factory = XmlPullParserFactory.newInstance();
            factory.setNamespaceAware(true);
            XmlPullParser xpp = null;
            xpp = factory.newPullParser();
            xpp.setInput(inputreader);
            int eventType = 0;
            eventType = xpp.getEventType();
            eventType = xpp.getEventType();
            while (eventType != XmlPullParser.END_DOCUMENT) {
                if(eventType == XmlPullParser.START_TAG) {
                    KEY = xpp.getName();
                    if(KEY.equalsIgnoreCase(TAGS.COUNTRIES)) {
                        arrCountires = new ArrayList<Country>();

                    }else if(KEY.equalsIgnoreCase(TAGS.COUNTRY)) {
                        country = new Country();
                        arrStates = new ArrayList<State>();
                        country.setCountryId(xpp.getAttributeValue(null, TAGS.ID));

                    }else if(KEY.equalsIgnoreCase(TAGS.STATE)) {
                        state = new State();
                        arrCities = new ArrayList<City>();
                        state.setStateId(xpp.getAttributeValue(null, TAGS.ID));

                    }else if(KEY.equalsIgnoreCase(TAGS.CITY)) {
                        city = new City();
                        city.setCityId(xpp.getAttributeValue(null, TAGS.ID));
                    }
                }else if(eventType == XmlPullParser.END_TAG) {
                    KEY = xpp.getName();
                    if(KEY.equalsIgnoreCase(TAGS.COUNTRY)) {
                        country.setArrStates(arrStates);
                        arrCountires.add(country);

                    }else if(KEY.equalsIgnoreCase(TAGS.COUNTRY_NAME)) {
                        country.setCountryName(VALUE);

                    }else if(KEY.equalsIgnoreCase(TAGS.STATE_NAME)) {
                        state.setStateName(VALUE);

                    }else if(KEY.equalsIgnoreCase(TAGS.STATE)) {
                        state.setArrCities(arrCities);
                        arrStates.add(state);

                    }else if(KEY.equalsIgnoreCase(TAGS.CITY)) {
                        arrCities.add(city);
                    }else if(KEY.equalsIgnoreCase(TAGS.CITY_NAME)) {
                        city.setCityName(VALUE);
                    }
                }else if(eventType == XmlPullParser.TEXT) {
                    VALUE = xpp.getText();
                }
                eventType = xpp.next();

    return arrCountires;

这里有一个代码，可以从资产中将文件作为inputstream打开

try {
    InputStream inputStream = v.getContext().getAssets().open("path of file");
    ArrayList<Country> arrCountries = parseCountry(this, inputStream);

} catch (IOException e1) {
    // TODO Auto-generated catch block
    e1.printStackTrace();
}

spCountry.setOnItemSelectedListener(OnCountrySelected);

try {
    InputStream inputStream = v.getContext().getAssets().open("path of file");
    ArrayList<Country> arrCountries = parseCountry(this, inputStream);

} catch (IOException e1) {
    // TODO Auto-generated catch block
    e1.printStackTrace();
}

CountryAdapter countryAdapter = new CountryAdapter(arrCountry);
            spCountry.setAdapter(countryAdapter);
