wifiダイレクトでファイル転送アプリを作りたいのですが、送受信のプログレスバーが更新されません

API 14+を使用しているため、ダイアログフラグメントを使用します
私のダイアログクラス
public class MyDialog extends DialogFragment {
ProgressBar mProgressBar;
String title;
public MyDialog (String title) {
this.title = title;
}
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setRetainInstance(true);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
View view = inflater.inflate(R.layout.popup, container);
mProgressBar = (ProgressBar)view.findViewById(R.id.pb);
getDialog().setTitle(title);
getDialog().setCanceledOnTouchOutside(false);
return view;
}
@Override
public void onDestroyView()
{
if (getDialog() != null && getRetainInstance())
getDialog().setDismissMessage(null);
super.onDestroyView();
}
@Override
public void onCancel(DialogInterface dialog) {
// TODO Auto-generated method stub
super.onCancel(dialog);
Toast.makeText(getActivity().getApplicationContext(), "Connection lost. Retry", Toast.LENGTH_SHORT).show();
getActivity().finish();
}
public void updateProgress(int percent)
{
mProgressBar.setProgress(percent);
}
}
コードが機能しない理由がわかりません。進行状況バーが更新されず、ファイルが送信されません。誰でも私を助けることができますか？前にthx
