在 API 22 字符串不更改的设备中更改应用程序语言

Question

我想在更改应用语言环境时更改字符串

有个人资料片段

    @Override
    public void onClick(View v) {
        Intent intent = null;
        switch (v.getId()) {
            case R.id.changeLanguageButton:
                if (PrefManager.getLocale(getActivity()).equals("en")) {
                    setLocale("ar");
                } else {
                    setLocale("en");
                }
                break;
        }
    }

    public void setLocale(String lang ) {
        Locale locale = new Locale(lang);
        Locale.setDefault(locale);
        Configuration config = new Configuration();
        config.locale = locale;
        config.setLayoutDirection(locale);
        getActivity().getBaseContext().getResources().updateConfiguration(config, getActivity().getApplication().getResources().getDisplayMetrics());
        PrefManager.saveLocale(getActivity(), lang);

        Intent intent = new Intent(getActivity(), SplashActivity.class);
        startActivity(intent);

    }

有飞溅Activity

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        if (PrefManager.getLocale(this) == null){
            setLocale("en");
        }else if (PrefManager.getLocale(this).equals("en")){
            setLocale("en");
        }else {
            setLocale("ar");
        }

        setContentView(R.layout.activity_splash);

        new Handler().postDelayed(new Runnable(){
            @Override
            public void run() {
                Intent mainIntent = new Intent(SplashActivity.this,MainActivity.class);
                Splash.this.startActivity(mainIntent);
                Splash.this.finish();
            }
        }, 3000);

    }

    public void setLocale(String lang) {
        Locale locale = new Locale(lang);
        Locale.setDefault(locale);
        Configuration config = new Configuration();
        config.locale = locale;
        config.setLayoutDirection(locale);
        this.getBaseContext().getResources().updateConfiguration(config, this.getApplication().getResources().getDisplayMetrics());
        PrefManager.saveLocale(this, lang);
    }

问题是此代码在 API 23 的设备中工作并翻译所有字符串但在 API 22 的设备中不起作用它只是改变布局方向

我的 minSDKVersion 19 & targetSDKVersion 29

如果有人感兴趣，我找到了答案

我将阿拉伯字符串文件名从“string (ar-rEG)”更改为“string (ar)”

而且效果很好
