好吧,夥計們。我正在做一個項目,我在操作欄中放了一個按鈕,從保加利亞語翻譯成英語,反之亦然。我在語言環境中進行了更改,但是我的問題是,在單擊該按鈕之後,應用程序中的語言會發生變化,但操作欄中按鈕上的文本不會變化。我已經創建了兩個文件夾values-bg和values-en,並且我爲這個按鈕所使用的字符串在兩個string.xmls中聲明,但是文本根本不會改變。更改語言環境後更改文本

這是代碼:

import java.util.Locale;

    @Override

     super.onCreate(savedInstanceState); 

     ActionBar bar = getActionBar(); 
     bar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#118cec"))); 

     setContentView(R.layout.activity_main);

     } 
     else if (v.getId() == hLink.getId()) { 

      Toast t = Toast.makeText(this, "Text",

      t.show(); 


      Intent i = new Intent(Intent.ACTION_VIEW); 
      i.setData(Uri.parse(url)); 
      startActivity(i); 
     } 

    }

      t.show(); 

      Locale mLocale = new Locale("bg"); 
      Locale.setDefault(mLocale); 
      Configuration config = getBaseContext().getResources() 
        .getConfiguration(); 
      if (!config.locale.equals(mLocale)) {

       aBtn.setOnClickListener(this); 

      } 
     } 

     return super.onOptionsItemSelected(item); 
    } 


} 

是否有可能以某種方式誇大菜單一次。在我改變區域設置後,我設置了新的活動,但不是新的菜單。我可以調用getMenuInflater()。inflate(R.menu.main,menu);不知何故在我的If塊?

可能還有很多的事情。請發佈您的代碼。 –

呼叫invalidateOptionsMenu()更改後的語言環境......或者只需重新啓動您的應用程序:)

非常感謝。這就是我一直在尋找的。這可能很容易,但我是Android新手,我很高興你幫助我:) –
