语言改变在android中不起作用？

Question

• 此代码无效，有什么问题，请任何人帮帮我..

  private void setLocaleLanguage(String languageSelection) {
  myLocaleLanguage = new Locale(languageSelection);
  Resources res = getResources();
  DisplayMetrics dm = res.getDisplayMetrics();
  Configuration conf = res.getConfiguration();
  if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
      Locale.setDefault(myLocaleLanguage);
      conf.setLocale(myLocaleLanguage);
      this.createConfigurationContext(conf);
  }else{
      conf.locale = myLocaleLanguage;
      Locale.setDefault(myLocaleLanguage);
      res.updateConfiguration(conf, this.getResources().getDisplayMetrics());
  }
  
  Intent refresh = new Intent(this, MainActivityBeforeLogin.class);
  startActivity(refresh);
  finish();
  

  }

Answer 1

而不是：

this.createConfigurationContext(conf);

使用：

res.updateConfiguration(conf, dm);

代码：

 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
    Locale.setDefault(myLocaleLanguage);
    conf.locale = myLocale;
    res.updateConfiguration(conf, dm);
}

将您的意图改为

 Intent i = new Intent(getApplicationContext(), MainActivityBeforeLogin.class);
i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i);
