TabWidget에서 직접 활동을 할 수 없습니다.

Question

TabWidget을 사용하여 소프트웨어를 코드화하려면 this 프로젝트를 다운로드하십시오. 나는 MainActivity 대신에 활동을 시도했지만 매번 실패합니다. 내 자신의 활동에 MainActivity (TRYTOCHANGEHERE있는 곳)을 변경하려했지만 작동하지 않습니다. 작동되도록 특수 설정을해야합니까?

Intent intent = new Intent(this, TRYTOCHANGEHERE-->MainActivity.class); 
     tabHost.addTab(tabHost.newTabSpec("Main") 
       .setIndicator("Main", res.getDrawable(R.drawable.ic_tab_main)) 
       .setContent(intent)); 

     Intent intent2 = new Intent(this, SetupActivity.class); 
     tabHost.addTab(tabHost 
       .newTabSpec("Setup") 
       .setIndicator("Setup", res.getDrawable(R.drawable.ic_tab_setup)) 
       .setContent(intent2)); 
     tabHost.setCurrentTab(0); 

Android에서 시작하므로 어리석은 일이 될 수 있습니다.

감사합니다 !!!!

내 응용 프로그램 컴파일 및 설치,하지만 난 그것을 실행할 때, 그것을 중지하고 내가 얻을 메시지 '예기치 않게 응용 프로그램이 중지되었습니다.'

내가 시작하려고하는 클래스는 정말 기본입니다.

import android.app.Activity; 
import android.os.Bundle; 
import android.widget.TextView; 

public class TestActivity extends Activity {   

    TextView hw = null; 

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

     hw = new TextView(this); 
     hw.setText("Hello World!"); 
     setContentView(hw); 
    } 

};
