Tab1

public class Tab1 extends Fragment {
    Context mContext;

    public Tab1(Context context) {
        mContext = context;
    }
    private TextSwitcher mSwitcher;
    Button button1;

   
    String textToShow[]={"Main HeadLine","Your Message","New In Technology","New Articles","Business News","What IS New"};
    int messageCount=textToShow.length;
    int currentIndex=-1;

    @Override
   public View onCreateView(LayoutInflater inflater,
                            ViewGroup container,Bundle savedInstanceState)
    {
        View view = inflater.inflate(R.layout.activity_tab1, null);
        super.onCreate(savedInstanceState);


        button1=(Button)view.findViewById(R.id.button1);
        mSwitcher = (TextSwitcher) view.findViewById(R.id.textSwitcher);
mSwitcher.setFactory(new ViewSwitcher.ViewFactory() {
    @Override
    public View makeView() {
        TextView myText = new TextView(Tab1.this);
        myText.setGravity(Gravity.TOP | Gravity.CENTER_HORIZONTAL);
        myText.setTextSize(36);
        return myText;
    }
});
      
       
        button1.setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {
                // TODO Auto-generated method stub
                currentIndex++;
                // If index reaches maximum reset it
                if (currentIndex == messageCount)
                    currentIndex = 0;
                mSwitcher.setText(textToShow[currentIndex]);
            }
        });
        return view;

    }
}

Horizontal pazing 에서 tab1 activity에 textswitcher를 사용하려합니다.

근데 저 위에 빨간글씨처럼 에러가 뜨는데 어찌해야하나요

Answer 1

저위에 빨간글씨처럼 뜨는게 어디를 말하는거죠? 

TextView myText = new TextView(<span style="color:#ff0000;">Tab1.this</span>);

여기 말하는건가요? Tab1.this 를 mContext로 바꿔보세여

그리고 위 내용이 맞다면 TextSwitcher랑은 아무런 상관이 없습니다.
