이 되었기 때문에 R.id.CPUinfo 텍스트 뷰와 R.id.memoryinfo 텍스트 뷰가 R.layout.main에 더 상주를하지 않는다, 당신이 전화를해야 적절한 Fragment의 onCreateView

예 :

public static class TabFragment extends Fragment { 

    public static final String ARG_OBJECT = "object"; 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
     Bundle savedInstanceState) { 

     Bundle args = getArguments(); 
     int position = args.getInt(ARG_OBJECT); 

     int tabLayout = 0; 
     switch (position) { 
     case 0: 
     tabLayout = R.layout.tab1; 
     break; 
     case 1: 
     tabLayout = R.layout.tab2; 
     break; 
     case 2: 
     tabLayout = R.layout.tab3; 
     break; 
     } 

     View rootView = inflater.inflate(tabLayout, container, false); 

     if (tabLayout == R.layout.tab1) {  
      TextView CPUinfo = (TextView) rootView.findViewById(R.id.CPUinfo); 
      CPUinfo.setText(getCPUinfo()); 
      TextView Memoryinfo = (TextView) rootView.findViewById(R.id.memoryinfo); 
      Memoryinfo.setText(getMemoryInfo()); 
     }  
     return rootView; 
    } 
}
