WebView链接未打开 [英] WebView Links not opening

问题描述

我正在尝试使用Android中的Webview打开链接. WebView中嵌入了一些链接.我的问题是webview没有打开任何不以www开头的链接.例如，www.google.com正常工作，而maps.google.com无效.我也曾尝试重写WebViewClient，但没有成功. 我注意到的一件事是，将Toast放入WebViewClient中，以查看正在调用的URL.它对于www.google.com而言显示完美，但对于其他链接则一无所获.在这种情况下，我认为WebViewClient不会被覆盖.可能是什么原因.我是否必须调用任何方法或webview的某些属性. 任何帮助将不胜感激.

I am trying to open a link using Webview in Android. There are some links embedded into WebView. My problem is webview is not opening any link that does not starts with www. For ex, www.google.com is working but maps.google.com is not.I have also tried to override WebViewClient but it didn't work. One thing I noticed is by putting Toast to see what url is being called in WebViewClient. It showed perfect for www.google.com but returned nothing for other links. I thing WebViewClient is not getting overriden in that case. What could be the reason. Do I have to call any ethod or some property of webview. Any help will be appreciated.

menuView.setWebViewClient(new WebViewClient() {
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            super.shouldOverrideUrlLoading(view, url);
            Toast.makeText(getApplicationContext(), "url:--" + url, Toast.LENGTH_LONG).show();          
            view.loadUrl(url);
            return false;
    }

    });

我已经设置的属性是:

menuView.setVerticalScrollBarEnabled(false);

menuView.setVerticalScrollBarEnabled(false);

    menuView.setHorizontalScrollBarEnabled(false);

    final WebSettings webSettings = menuView.getSettings();
    menuView.getSettings().setJavaScriptEnabled(true);
    webSettings.setJavaScriptCanOpenWindowsAutomatically(true);
    webSettings.setSupportMultipleWindows(true);

    webSettings.setPluginState(PluginState.ON);
    webSettings.setLayoutAlgorithm(LayoutAlgorithm.SINGLE_COLUMN);

    menuView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
    menuView.getSettings().setBuiltInZoomControls(true);
    // Below required for geolocation
    menuView.getSettings().setJavaScriptEnabled(true);
    menuView.getSettings().setGeolocationEnabled(true);

    webSettings.setGeolocationEnabled(true);

    webSettings.setJavaScriptCanOpenWindowsAutomatically(true);

// in oncreate 
webview.setWebChromeClient(new wecrome());
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setLoadsImagesAutomatically(true);
webview.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
webview.setWebViewClient(new MyBrowser());
webview.getSettings().setPluginState(PluginState.ON);
webview.loadUrl("http://www.example.net/locations/");

//inner class 
private class MyBrowser extends WebViewClient {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            view.addJavascriptInterface(new Object() {
                @JavascriptInterface
                public void performClick() throws Exception {
                    Log.d("LOGIN::", "Clicked");
                    Toast.makeText(googleplus.this, "Login clicked",
                            Toast.LENGTH_LONG).show();
                }
            }, "login");
            return true;
        }

        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            // TODO Auto-generated method stub

            System.out.println("started");
            pd.show();
            super.onPageStarted(view, url, favicon);

        }

        @Override
        public void onPageFinished(WebView view, String url) {
            // TODO Auto-generated method stub
            pd.dismiss();
            System.out.println("ends");
            super.onPageFinished(view, url);

        }

    }
