Android WebView如何隐藏地址栏，用WebView 来显示网页内容

private WebView webView;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.requestWindowFeature(Window.FEATURE_NO_TITLE);
    //setContentView(R.layout.main);
    // setContentView(R.layout.activity_main);
    //实例化WebView对象
    webView = new WebView(this);
    //设置WebView属性，能够执行Javascript脚本
    webView.getSettings().setJavaScriptEnabled(true);
    //加载需要显示的网页
    webView.loadUrl("http://www.baidu.com/");
    //设置Web视图
    webView.setWebViewClient(new MyWebViewClicnt());
    setContentView(webView);

}

private class MyWebViewClicnt extends WebViewClient{

    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        view.loadUrl(url);
        return true;
    }
}
