編輯：Java代碼的

public class Fragment5 extends Fragment { 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 
     ViewGroup rootView = (ViewGroup) inflater.inflate(
       R.layout.fragmentdescrip5, container, false); 


     TextView mytxtview = (TextView) rootView.findViewById(R.id.textViewNamefrag5); 
     mytxtview.setMovementMethod(new ScrollingMovementMethod()); 



     return rootView; 
    } 

}

刪除maxLines="25";這將文本的長度限制爲25行。
