StringBuffer 배열을 이용해서 플리퍼할때마다 StringBuffer의 배열 인덱스로 다음 StringBuffer 를 표시하도록 하려고합니다.
그러나 String배열을 사용했을때는 잘되던것이  StringBuffer만 사용하면 어플이 죽어버립니다.
플리퍼를 이용해서 해보려고 해도 기본적으로 아예 출력이 안되버리니 힘드네요
해결방법이 어떤것이 있을까요?

에러는 이렇게 납니다.

그리고
제가 작성한 코드는

public class textread extends Activity //implements View.OnTouchListener
{
    /** Called when the activity is first created. */
 ViewFlipper flipper;
 TextView tv ;
 float moveatrightx=0.0f;
 float moveatleftx=0.0f;
 int pagenum =0;
 StringBuffer [] texts;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        flipper = (ViewFlipper)findViewById(R.id.myflipper);      
        tv = (TextView)findViewById(R.id.firstview);
          
        texts = new StringBuffer[2];
        
        flipper.setOnTouchListener(this);
          texts[0].append("asdlkfjalksdjflkajsdflkj");

       
        tv.setText(texts[0]);
        }
}
