android studio kann kein spezifisches Gebietsschema einstellen

Question

Ich kann kein spezifisches Gebietsschema beim Drücken der Taste einstellen. wenn der Knopf auf die spezifische Sprache drückt. Ich möchte, dass die Schaltfläche zur Hauptseite umleitet und dort die Grundstruktur rendert, die aus fünf Schaltflächen besteht.

Muss ich die Sprachen im Emulator installiert haben? sie sind nicht in dem Emulator

protected void onCreate(Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.selectlocale); 

    Button eng =(Button)findViewById(R.id.en); 
    eng.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      Locale local=new Locale("en"); 
      GlobalClass globalvariable=(GlobalClass)getApplicationContext(); 
      globalvariable.setLocale(local); 
      Intent ints =new Intent(getApplication(),MainMenu.class); 
      startActivity(ints); 
     } 
    }); 

    Button dar =(Button)findViewById(R.id.dr); 
    dar.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) 
     { 
      Locale local=new Locale("fa"); 
      GlobalClass globalvariable=(GlobalClass)getApplicationContext(); 
      globalvariable.setLocale(local); 
      Intent ints =new Intent(getApplication(),MainMenu.class); 
      startActivity(ints); 
     } 
    }); 

    Button pas =(Button)findViewById(R.id.ps); 
    pas.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      Locale local=new Locale("ps"); 
      GlobalClass globalvariable=(GlobalClass)getApplicationContext(); 
      globalvariable.setLocale(local); 
      Intent ints =new Intent(getApplication(),MainMenu.class); 
      startActivity(ints); 
     } 
    }); 
} 

dann Mainmenu Aktivität

protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
    GlobalClass glb=(GlobalClass)getApplicationContext(); 
    Locale loc =glb.getLocale(); 
    Locale.setDefault(loc); 
    Configuration config =new Configuration(); 
    config.locale=loc; 
    getBaseContext().getResources().updateConfiguration(config,getBaseContext().getResources().getDisplayMetrics()); 
    setContentView(R.layout.main_menu); 
    }

    public void setLocale(Locale loc)

} 

Answer 1

Dies ist, was ich in XML-Datei verpaßt (oben ist ein kompletter Code, das funktioniert)

nur statt

ändern

android:text="Link1" 

sollte es von r sein eSource

android:text="@string/link1" 

Und nicht vergessen GlobalClass in AndroidManifest

<application 
    android:allowBackup="true" 
    android:icon="@mipmap/ic_launcher" 
    android:label="@string/app_name" 
    android:supportsRtl="true" 
    android:theme="@style/AppTheme" 

    android:name="com.example.sepia2.myapplication.GlobalClass"> 
    <activity android:name=".MainActivity"> 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 

      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity> 
    <activity android:name=".settlocale" /> 
    <activity android:name=".Main3Activity" /> 
    <activity android:name=".MainMenu"></activity> 


    </application>
