public class AircraftFragmentTab extends Fragment{
  private String ac;

  public AircraftFragmentTab(String AC){
      ac = AC;

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

         ??? getWindow().setLayout(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
          WebView wv = (WebView) aircraftView.findViewById(R.id.webac);
          wv.getSettings().setJavaScriptEnabled(true);
          wv.loadUrl("http://ABCD/ACInfo.aspx?AC=" + ac);

         return aircraftView;
     }

}

我正在使用webView,类从Fragment扩展.我怎么在这里使用getWindow()？

我试图在屏幕中央显示进度条,但它不会显示在中心.下面是我的布局.我在这做错了什么？基本上这是一个布局,以显示图像和Android画廊小部件在上面.当用户点击缩略图时,我正在从网络加载图像,我想在加载图像时显示进度对话框.
