在Android

Question

如何在Android中选择选项language后刷新应用。 选择后退活动后，布局不刷新。 这是我的代码。

Locale localeIdn = new Locale("in");
Locale.setDefault(localeIdn);
Configuration config1 = new Configuration();
config1.locale = localeIdn;
getBaseContext().getResources().updateConfiguration(config1, getBaseContext().getResources().getDisplayMetrics());
finish();
Intent intent = new Intent(SettingPageActivity.this, MainActivity.class);
startActivity(intent);
break;

Answer 1

试试这个：

Intent intent = getIntent();
finish();
startActivity(intent);

或者这个：

this.recreate();

Answer 2

希望它对你有用。

 Locale locale = new Locale("yourlanguageid");
 LanguageHelper.changeLocale(mActivity.getResources(), locale);
 Intent intent = new Intent(mActivity, mActivity.getClass());
 intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
 mActivity.startActivity(intent);

public class LanguageHelper {
    /**
     * Change locale.
     *
     * @param res    the res
     * @param locale the locale
     */
    public static void changeLocale(Resources res, String locale) {

        Configuration config;
        config = new Configuration(res.getConfiguration());


        switch (locale) {
            case "yourlanguageid":
                config.locale = new Locale("yourlanguageid");
                break;
            case "en":
                config.locale = Locale.ENGLISH;
                break;
        }
        res.updateConfiguration(config, res.getDisplayMetrics());
    }

    public static Locale getLocale(Resources res) {
        Configuration config;
        config = new Configuration(res.getConfiguration());
        return config.locale;
    }
}
