我知道以前有人问过这个问题,但是我已经尝试了其他问题的所有“解决方案”,但我仍然无法实现我想要做的事情。我已经搜索和搜索,并尝试过。请原谅我。我只是想在我的 WebView 上方显示我的按钮行,以便它与我的应用程序中的其余活动保持一致(它们都在顶部有按钮行)。似乎我已经尝试了所有可能的布局组合,但无济于事。它在图形布局(Eclipse)中正确显示,但在手机和模拟器上它只显示 WebView、全屏、没有按钮......任何帮助将不胜感激!

这是我的xml:

}

我已经注释掉了所有的菜单按钮(我试图在 webview 上方显示的按钮),直到我最终让它们通过 xml 显示。但是,每当我取消注释按钮及其侦听器时,应用程序会在尝试进入此活动时崩溃。

您的代码没有使用您的 XML 布局,而是在代码中创建自己的 WebView 并将其设置为视图,以便它完全绕过您的 XML。

我在这里提供了一些应该使它起作用的更改。请特别注意 setContentView 行和以下行,这些都是使用 XML 布局的内容。您可能需要更改布局的名称 (R.layout.whatever) 和 webview id (R.id.webview)。我把它放在这里可能有一些解析错误,可能错过了一个右括号。为了简单起见,我删除了许多注释掉的代码。

@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView( R.layout.xmlLayout );

    itsMeLogin = (WebView)findViewById( R.id.webview );

    detector = new SimpleGestureFilter(this,this);

    Toast.makeText(this, "Just Swipe To Exit", Toast.LENGTH_LONG).show();


    itsMeLogin.getSettings().setJavaScriptEnabled(true); // JavaScript enabled

    getWindow().requestFeature(Window.FEATURE_PROGRESS); // Show progress bar of page loading

    final Activity itsMeActivity = this;


    itsMeLogin.setWebChromeClient(new WebChromeClient() {

        public void onProgressChanged(WebView view, int progress){

            // Activities and WebViews measure progress with different scales.
            // The progress meter will automatically disappear when we reach 100%
            itsMeActivity.setProgress(progress * 100);

        }

    });

    itsMeLogin.setWebViewClient(new WebViewClient(){

        public void onReceivedError(WebView view, int errorCode, String description, String failingUrl){

            Toast.makeText(itsMeActivity, "Oh no! " + description, Toast.LENGTH_SHORT).show();

        }


    });

    itsMeLogin.loadUrl("http://www.google.com");
}

这也是来自类似布局的我的 XML 文件,尽管您可能会使用编辑后的代码。
