Android在进度条加载完成后隐藏标题栏

我试图在进度条加载完毕后隐藏标题栏。有人能告诉我怎么做吗？谢谢

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


        //this.requestWindowFeature(Window.FEATURE_CUSTOM_TITLE); **//Putting this make the whole title bar hidden**
        this.getWindow().requestFeature(Window.FEATURE_PROGRESS);
        this.getWindow().requestFeature(Window.FEATURE_INDETERMINATE_PROGRESS);

        setContentView(R.layout.main);

一堆代码

webView.setWebChromeClient(new WebChromeClient() {
            public void onProgressChanged(WebView view, int progress)   
            {
             //Make the bar disappear after URL is loaded, and changes string to Loading...
            MyActivity.setTitle("Loading...");
             MyActivity.setProgress(progress * 100); //Make the bar disappear after URL is loaded

             // Return the app name after finish loading
                if(progress == 100)

             this.requestWindowFeature(Window.FEATURE_NO_TITLE);**//Not Working (shows Error The method requestWindowFeature(int) is undefined for the type new WebChromeClient(){} )**  
              //MyActivity.setTitle(R.string.app_name);

              }



            });
        webView.setWebViewClient(new InsideWebViewClient());


    }

您需要将以下语法写入AndroidManifest.xml文件

android:theme="@android:style/Theme.NoTitleBar.Fullscreen"

如果您想通过在Activity中编码来实现，那么可以在Activity的OnCreate（）方法中使用以下代码

requestWindowFeature(Window.FEATURE_NO_TITLE); 
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

谢谢路西法的回复。但这样做将隐藏我的进度条，使其无法显示在标题栏上。在webview完成加载后，是否有其他选项可以显示进度栏并隐藏标题栏？我在实现代码AndroidRuntimeException:requestFeature（）时遇到此错误，必须在添加内容之前调用
