WebView不加载网页

我正在使用WebView加载网站。 但是,当特定的网站被加载时,它非常缓慢并且正在泄漏。 我使用下面的代码加载WebView

 @Override protected void onNewIntent(Intent intent) { if (intent.getStringExtra("url") != null) { webView.loadurl(intent.getStringExtra("url")); } } 

但我打电话给webView.loadUrl(Config.URL);Config.URL可能包含与上面指定的相同的url)在用以下方法初始化WebView之后在onCreate()方法中。

  this.webView = (WebView) findViewById(R.id.wv); this.webView.getSettings().setJavaScriptEnabled(true); this.webView.getSettings().setLoadsImagesAutomatically(true); this.webView.getSettings().setDomStorageEnabled(true); this.webView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY); MyClient client = new MyClient(WebActivity.this, (ProgressBar)findViewById(R.id.progressBar)); webView.setWebViewClient(client); 

加载从onCreate()工作正常(不好,它太慢了)。 但是从onNewIntent()加载相同的URL 不工作! 。 在onNewIntent()没有URL使用onNewIntent()加载,当前页面变得不可移动。 即。 滚动条在WebView中移动,但页面不滚动。 我在onCreate()testing了相同的URL,它正在工作。

为了做到这一点,我传递的URL

 intent.putExtra("url", Config.URL+targetUrl); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP); 

与通知的未决意图。 虽然它在某些设备上工作,即Google Nexus。 但是在大部分手机上都不行。 我有

 android:hardwareAccelerated="true" 

我的客户

 public class MyClient extends WebViewClient{ private Context context; private Activity activity; private Handler handler; private Runnable runnable; private ProgressBar viewBar; private String ret,ret2; public void setFirstLoad(boolean firstLoad) { this.firstLoad = firstLoad; } private boolean firstLoad=false; public MyClient(Activity activity, ProgressBar bar) { this.context = activity.getApplicationContext(); this.activity = activity; viewBar=bar; handler=new Handler(); } @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { /*if (url.startsWith("tel:")) { Intent intent = new Intent(Intent.ACTION_DIAL, Uri.parse(url)); intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.startActivity(intent); }else if(url.startsWith("http:") || url.startsWith("https:")) { *//*view.setVisibility(View.GONE); viewBar.setVisibility(View.VISIBLE);*//* view.loadUrl(url); } return true;*/ if (Uri.parse(url).getHost().equals("www.somepage.com")) { return false; } // Otherwise, the link is not for a page on my site, so launch another Activity that handles URLs try { Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url)); intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.startActivity(intent); Answers.getInstance().logShare(new ShareEvent() .putContentId(Build.USER) .putMethod(shareName(url)) .putContentName(contentDecode(url)) .putContentType("news_share")); }catch (android.content.ActivityNotFoundException e){ Log.e("Activity not found",e.toString()); Toast.makeText(context,"Application not found",Toast.LENGTH_LONG).show(); } return true; } @Override public void onReceivedError(final WebView view, int errorCode, String description, final String failingUrl) { //Clearing the WebView try { view.stopLoading(); } catch (Exception e) { } try { view.clearView(); } catch (Exception e) { } if (view.canGoBack()) { view.goBack(); } view.loadUrl("about:blank"); //Showing and creating an alet dialog AlertDialog.Builder alertDialog = new AlertDialog.Builder(activity); alertDialog.setTitle("Error"); alertDialog.setMessage("No internet connection was found!"); alertDialog.setPositiveButton("Retry", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { view.loadUrl(failingUrl); } }); AlertDialog alert = alertDialog.create(); alert.show(); //Don't forget to call supper! super.onReceivedError(view, errorCode, description, failingUrl); } @Override public void onLoadResource(final WebView view, String url) { super.onLoadResource(view, url); //injectScriptFile(view, "js/script.js"); injectCSS(view,"css/style.css"); if (firstLoad){ firstLoad=false; view.setVisibility(View.INVISIBLE); viewBar.setVisibility(View.VISIBLE); runnable=new Runnable() { @Override public void run() { viewBar.setVisibility(View.GONE); view.setVisibility(View.VISIBLE); } }; handler.postDelayed(runnable,2000); } // test if the script was loaded // view.loadUrl("javascript:setTimeout(hideMe(), 200)"); } /*@Override public void onPageFinished(final WebView view, String url) { //System.gc(); }*/ @Override public void onPageFinished(WebView view, String url) { super.onPageFinished(view, url); System.gc(); } 

问题是: onNewIntent()使用loadurl()方法时会出现什么问题?

尝试从你加载webview的地方

  web.setWebViewClient(new WebViewClient() { @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { return super.shouldOverrideUrlLoading(view, url); } }); 

你可以使用webclient来处理web视图。 在这里,我包括加载的JavaScript。

  String aboutURL="YOUR URL"; final ProgressDialog pd = ProgressDialog.show(, "", "Please wait", true); WebSettings settings=Webview.getSettings(); settings.setJavaScriptEnabled(true); settings.setAppCacheEnabled(true); settings.setDomStorageEnabled(true); settings.setLoadsImagesAutomatically(true); settings.setDatabaseEnabled(true); settings.setRenderPriority(WebSettings.RenderPriority.HIGH); settings.setCacheMode(WebSettings.LOAD_NO_CACHE); settings.setSupportZoom(true); settings.setBuiltInZoomControls(true); Webview.setWebViewClient(new WebViewClient() { public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) { Toast.makeText(activity, description, Toast.LENGTH_SHORT).show(); } @Override public void onPageStarted(WebView view, String url, Bitmap favicon) { pd.show(); } @Override public void onPageFinished(WebView view, String url) { pd.dismiss(); } }); Webview.loadUrl(aboutURL); 

这里的加载是基于networking进行处理的

使用处理程序来发布一个延迟行动,如下所示,将解决这个问题,但我不知道为什么。

 new Handler().post(webView.loadurl(url));
