웹뷰 만드는중에 클래스 nullpoint 문제..-_-;;

Question

웹뷰를 만들어 보다가 에러가 나는데 이유를 모르겠네요

단순한 코드입니다만..;;

 

58번째 줄에서 오류가 난다고 하는데.. 문제의 58번째 줄은 아래와 같습니다.

  webView.setWebViewClient(new myWebViewClient());

이 부분에서 자꾸 널포인트 에러가 발생합니다.;;

도무지 뭐가 잘못된지 모르겠네요...;;

 

TextView edtUrl;
Button btnMove, btnBack;
WebView webView;

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

    webView = (WebView)findViewById(R.id.webView);

    webView.setWebViewClient(new myWebViewClient());

    WebSettings webSet = webView.getSettings();
    webSet.setBuiltInZoomControls(true);

     
    private class  myWebViewClient extends WebViewClient {

@Override  public boolean shouldOverrideUrlLoading(WebView view, String url) { return super.shouldOverrideUrlLoading(view, url);  } } 

} private class myWebViewClient extends WebViewClient { @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { return super.shouldOverrideUrlLoading(view, url); } }
