Question

我的应用程序需要支持多语言。我想从应用程序的所有活动中更改应用程序语言。所以我使用Base_Activity并将微调器放在操作栏中。问题是在这里改变语言。当我在微调器中触发某个项来更改语言时，它不会改变。但在触发该项目并转到下一个活动后，它会在那里更改。我试图在每次触发获取触发语言后刷新页面。当选择了微调器中的语言项时，如何使用另一个语言刷新页面。我的代码看起来像这样;

public class Base_Activity extends Activity {

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.main, menu);

    final Spinner spinner = (Spinner) menu.getItem(0).getActionView()
            .findViewById(R.id.spinner);

    ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
            this, R.array.languages, R.layout.spinner_row);
    spinner.setAdapter(adapter);

    spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

        // private String currentLanguage;

        @Override
        public void onItemSelected(AdapterView<?> arg0, View arg1,
                int arg2, long arg3) {

            // currentLanguage = spinner.getSelectedItem().toString();

            Locale locale = null;
            switch (arg2) {
            case 0:
                locale = new Locale("en_US");
                break;
            case 1:
                locale = new Locale("fi");
                break;
            case 2:
                locale = new Locale("fr");
                break;
            case 3:
                locale = new Locale("de");
                break;
            case 4:
                locale = new Locale("sk");

                break;
            case 5:
                locale = new Locale("pl");
                break;

            default:
                locale = new Locale("en_US");
                break;
            }
            Locale.setDefault(locale);
            Configuration config = new Configuration();
            config.locale = locale;
            getBaseContext().getResources().updateConfiguration(config,
                    getBaseContext().getResources().getDisplayMetrics());

            startActivity();
        }

        private void startActivity() {
            overridePendingTransition(0, 0);
            Log.i("DEBUG", "GATEWAY");

        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
            Locale.setDefault(Locale.ENGLISH);

        }

    });
    return super.onCreateOptionsMenu(menu);
}

}

Answer 1

Locale localeNew = new Locale(locale); 
Locale.setDefault(localeNew);

Configuration configNew = new Configuration();
configNew.locale = localeNew;

getBaseContext().getResources().updateConfiguration(configNew, null);

触发语言更改项时刷新活动
