set new content view after running thread
===

I'm creating a startup activity for an application that downloads and parses some data. While it is loading i want to view my startup_loading.xml file, which contains a progressbar and a textview which is set to "loading".
Everything i need to do in the startup is put in a thread, the startUp thread. After running this thread the data is loaded, and then i want to show a new view: startup_loaded.xml which contains two buttons which send you to different activities in the application. 

But i have troubles using two views and displaying them at the time i want to.
I thought that if i put the 

>  setContentView(R.layout.startup_loaded);

at the end of the runnable of my thread it would work, but i get an error that that is impossible 

> CalledFromWrongThreadException: Only the original thread that created
> a view hierarchy can touch its views.

I thought i could fix it like this:
   

    	         @Override
    	    public void onCreate(Bundle savedInstanceState)
    	      {
    	        super.onCreate(savedInstanceState);
    	        
    	        startUp.start();
    	        String language =  Locale.getDefault().getISO3Language();
    	        if (startUp.isAlive()){
    	        	setContentView(R.layout.startup_loading);
    	        	tv1=(TextView)findViewById(R.id.tvloading);
    	        	if(language.equals("nld")){
    	        		tv1.setText("bijwerken");
    	        	}else{
    	        		tv1.setText("loading");
    	        	}
    		        pbar=(ProgressBar)findViewById(R.id.progressBar1);
    		        pbar.setVisibility(1);
    	        }else{
    				setContentView(R.layout.startup_loaded); 
    	        }
    	        
    			
    	        
    	      }
    	        Thread startUp= new Thread(){
            		public void run() {
    // all the loading
    }
    };

But this didn't work either: my startup_loaded never appeared.
I tried finishing my thread (`finish();` at the end of the runnable), but it finished by total app. Anyone knows what to do?
