该应用程序在 nougat api 7 ++ 上没有获得本地化更改效果 [英] The app doesn't get the localization change effect on nougat api 7 ++

问题描述

我的 spinner 有一个自定义适配器:

I have a custom adapter for my spinner:

ArrayAdapter<String> adapter = new ArrayAdapter<String>(context, android.R.layout.simple_spinner_item) {

      .............

    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    adapter.add(context.getResources().getString(R.string.value1));
    adapter.add(context.getResources().getString(R.string.value2));
    adapter.add(context.getResources().getString(R.string.hint));
    spinner.setAdapter(adapter);

每件事都按预期工作，但列表适配器，当我更改应用程序语言时，每件事都会得到语言更改效果，但列表适配器没有.

Every thing work as expect but list adapter, when i change the application language every thing got the language change effect but the list adapter don't.

我有两种语言的资源.

我正在通过这种方法更改语言:

I'm changing language via this method:

public  void setLocale(String lang) {
    Locale myLocale = new Locale(lang);
    Resources res = getResources();
    DisplayMetrics dm = res.getDisplayMetrics();
    Configuration conf = res.getConfiguration();
    conf.locale = myLocale;
    res.updateConfiguration(conf, dm);

}

我在像 lolipop 这样的低端设备上测试了这个案例后，它也能正常工作，这是 android oreo 8.0 的当前问题.

After i test the case on lower device like lolipop it's worked as well, the current issue with android oreo 8.0.

因为 conf.locale = myLocale; 在 API 级别 24 中已弃用.

Since conf.locale = myLocale; was deprecated in API level 24.

所以我没有直接使用 conf.locale = myLocale;.使用 getLocales() 和 setLocales(LocaleList).如果只需要主要语言环境，getLocales().get(0) 现在是首选访问器.

So i didn't use conf.locale = myLocale;directly. Use getLocales() and setLocales(LocaleList). If only the primary locale is needed, getLocales().get(0) is now the preferred accessor.

另外 updateConfiguration 在 API 级别 25 中被弃用，我使用了 createConfigurationContext (Configuration overrideConfiguration) 代替.

Also updateConfiguration was deprecated in API level 25, I used createConfigurationContext (Configuration overrideConfiguration) instead.

但是没有用，我是不是遗漏了什么?

But it didn't work, Is i missing something?

推荐答案

在将 Activity context 而不是 applicationContext 传递给 spinnerAdapter.

This issue fixed after passing the Activity context instead of applicationContext to the spinnerAdapter.

我只是将 spinnerAdapter = new SpinnerAdapter(getApplicationContext()); 更改为spinnerAdapter = new SpinnerAdapter(MainActivity.this);
