Android WebView无法加载URL [英] Android WebView not loading URL

问题描述

我想在WebView

我使用了以下代码:

webView = (WebView) findViewById(R.id.webview1);
webView.setWebViewClient(new HostsWebClient());
webView.getSettings().setPluginState(PluginState.ON);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(false);
webView.getSettings().setPluginsEnabled(true);
webView.getSettings().setSupportMultipleWindows(false);
webView.getSettings().setSupportZoom(false);
webView.setVerticalScrollBarEnabled(false);
webView.setHorizontalScrollBarEnabled(false);

webView.loadUrl(URL);

但是当我执行它时，我无法加载该URL.我的网页不可用.

But when I execute it, I'm not able to load the url. I am getting web page not available.

有人可以帮忙吗?

推荐答案

您是否已在清单文件中添加了Internet权限?如果没有，请添加以下行.

Did you added the internet permission in your manifest file ? if not add the following line.

 <uses-permission android:name="android.permission.INTERNET"/> 

希望这会对您有所帮助.

hope this will help you.

使用以下几行.

    public class WebViewDemo extends Activity {


        private WebView webView;


        Activity activity ;
        private ProgressDialog progDailog; 

        @SuppressLint("NewApi")
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);

            activity = this;

            progDailog = ProgressDialog.show(activity, "Loading","Please wait...", true);
            progDailog.setCancelable(false);



           webView = (WebView) findViewById(R.id.webview_compontent);



           webView.getSettings().setJavaScriptEnabled(true);     
           webView.getSettings().setLoadWithOverviewMode(true);
           webView.getSettings().setUseWideViewPort(true);        
            webView.setWebViewClient(new WebViewClient(){

                @Override
                public boolean shouldOverrideUrlLoading(WebView view, String url) {
                    progDailog.show();
                    view.loadUrl(url);

                    return true;                
                }
                @Override
                public void onPageFinished(WebView view, final String url) {
                    progDailog.dismiss();
                }
            });

            webView.loadUrl("http://www.teluguoneradio.com/rssHostDescr.php?hostId=147");

           }
    }
