由於近期應用加強了對多語言的適配,所以現在應用內有n種語言(10多種),然後統計的時候產品說只要上傳英文的字串.所以對於應用內的資料,在不修改語言的前提下,要將上傳的字串統一為英語.

廢話不多說,直接附上程式碼

public class LanguageUtil {

    public static final String TAG = "LanguageUtil";
    private static final String APPNAME = "you app packagename"
 
;
    public static final String ERROR_LABEL = "";
    private static final String DEFAULT_COUNTRY = "US";
    private static final String DEFAULT_LANGUAGE = "en";

    public static String getStringByLocale(Context context, int stringId, String language, String country) {
        /*for (Locale locale : getAvailableLocales()) {

            String lang = locale.getLanguage();
            String coun = getCountryPrivate(locale);
            String localeStr = country.equals("") ? language : (language + "_" + country);

            Loger.w("ruijie", "language = " + lang + ", country = " + coun + "," +
                    "localeStr = " + localeStr);
        }*/
 

        Resources resources = getApplicationResource(context.getApplicationContext().getPackageManager(),
                APPNAME, new Locale(language, country));
        if (resources == null) {
            return ERROR_LABEL;
        } else {
            try {
                return resources.getString(stringId);
            } catch
 
 (Exception e) {
                return ERROR_LABEL;
            }
        }
    }

    public static String getStringToEnglish(Context context, int stringId) {
        return getStringByLocale(context, stringId, DEFAULT_LANGUAGE, DEFAULT_COUNTRY);
    }

    private static Resources getApplicationResource(PackageManager pm, String pkgName, Locale l) {
        Resources resourceForApplication = null;
        try {
            resourceForApplication = pm.getResourcesForApplication(pkgName);
            updateResource(resourceForApplication, l);
        } catch (PackageManager.NameNotFoundException e) {

        }
        return resourceForApplication;
    }

    private static void updateResource(Resources resource, Locale l) {
        Configuration config = resource.getConfiguration();
        config.locale = l;
        resource.updateConfiguration(config, null);
    }

}

思路在於通過應用名找到對於的應用的Resources,在不修改resources的前提下,不影響當前應用的語言,獲取其資源.同理,只要知道其他應用的包名,可以獲取其所有的字串.

後來在測試種,給一個bean設定了一個字串id,如R.string.appname:
Bean bean = new Bean();
bean.setId(R.string.appname);
這樣進行設定之後,會發現錯誤.會丟擲ResourceNotFoundException,這是因為對於字串,或者圖片drawable之類進行id獲取,需要通過以下方法進行獲取:

int stringId = context.getResources().getIdentifier(resourceId, "srting", "your package name");
int drawableId = context.getResources().getIdentifier(resourceId, "drawable", "your package name");

這樣,經過這樣的方法,我們可以輕鬆的拿到字串了.用法如下:
String appName = LanguageUtil.getStringToEnglish(context, stringId);

如果要獲取指定國家和語言的字串,同理,加入國家和語言即可:
String appName = LanguageUtil.getStringByLocale(context, stringId, “en”, “US”);
