如果需要的Android超时网页视图超过一定时间更长的时间来装载 [英] Android Timeout webview if it takes longer than a certain time to load
问题描述
我想我超时的WebView，如果它需要很长的时间来加载显示错误信息。我使用 setWebViewClient ，因为我需要使用公共无效onReceivedSslError（的WebView视图，SslErrorHandler处理器，SslError错误） 。
I Want to timeout my webview if it takes a long time to load showing an error message. I'm using setWebViewClient because I need to use the public void onReceivedSslError (WebView view, SslErrorHandler handler, SslError error).
我一直在四处寻找，看见我可以使用的方法 onProgressChanged（的WebView观点，诠释newProgress）。现在我不能使用 setWebViewClient 这种方法并不能弄清楚如何去解决这个问题。另一个问题我是进度条永远不会消失，一旦加载页面时，我不能断点添加到方法公共无效onPageFinished（的WebView视图，字符串URL）或者
I've been looking around and saw I can use the method onProgressChanged(WebView view, int newProgress). Now I can't use this method in setWebViewClient and can't figure out how to go about solving this problem. Another issue I have is that the progress bar never goes away once the page is loaded, I can't add a breakpoint to the method public void onPageFinished(WebView view, String url) either.
Web视图设置方法：
public void WebViewSettings(){
webView = (WebView) findViewById(R.id.webview);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setBuiltInZoomControls(true);
webView.getSettings().setSupportZoom(true);
webView.getSettings().setLoadWithOverviewMode(true);
webView.canGoBack();
webView.setWebViewClient(new WebViewClient(){
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (Uri.parse(url).getHost().equals(urlString)) {
// This is my web site, so do not override; let my WebView load the page
return false;
}
// Otherwise, the link is not for a page on my site, so launch another Activity that handles URLs
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(intent);
return true;
}
@Override
public void onLoadResource(WebView view, String url) {
// Check to see if there is a progress dialog
if (progressDialog == null) {
progressDialog = new ProgressDialog(context);
progressDialog.setTitle("Loading...");
progressDialog.setMessage("Please wait.");
//progressDialog.setCancelable(false);
progressDialog.setIndeterminate(true);
progressDialog.show();
}
}
@Override
public void onPageFinished(WebView view, String url) {
// Page is done loading;
// hide the progress dialog and show the webview
if (progressDialog.isShowing()) {
progressDialog.dismiss();
progressDialog = null;
webView.setEnabled(true);
}
}
@Override
public void onReceivedSslError (WebView view, SslErrorHandler handler, SslError error) {
handler.proceed();
}
@Override
public void onReceivedError(WebView view, int errorCod,String description, String failingUrl) {
Toast.makeText(context, "Your Internet Connection May not be active Or " + description , Toast.LENGTH_LONG).show();
}
});
}
所以我的问题是，一旦网页加载进度条不会被删除，我需要超时web视图，如果它接管了一定的时间来加载。它看起来像显示进度条，然后消失了像它应该，然后重新开始，并不会停止加载。谢谢
So the issues I have are the progress bar doesn't get removed once the web page has loaded and I need to timeout the webview if it take over a certain amount of time to load. It looks like the progress bar is shown, then is disappears like it should, then starts loading again and wont stop. Thanks
推荐答案
我已经更新您的WebView设置方法请在下面找到更新code。
我添加了一个loaderTimerTask类。增加了code定时器和更多的理解提出意见。如果您有需要请更新此code。
I have updated your webview setting method please find below updated code. I have added one loaderTimerTask class. Added code for timer and put comment for more understanding. Please update this code if you need.
private boolean isPageLoadedComplete = false; //declare at class level
public void WebViewSettings(){
webView = (WebView) findViewById(R.id.webview);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setBuiltInZoomControls(true);
webView.getSettings().setSupportZoom(true);
webView.getSettings().setLoadWithOverviewMode(true);
webView.canGoBack();
/**
*I had put code here
*/
Timer myTimer = new Timer();
//Start this timer when you create you task
myTimer.schedule(loaderTask, 3000); // 3000 is delay in millies
webView.setWebViewClient(new WebViewClient(){
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (Uri.parse(url).getHost().equals(urlString)) {
// This is my web site, so do not override; let my WebView load the page
return false;
}
// Otherwise, the link is not for a page on my site, so launch another Activity that handles URLs
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(intent);
return true;
}
@Override
public void onLoadResource(WebView view, String url) {
// Check to see if there is a progress dialog
if (progressDialog == null) {
progressDialog = new ProgressDialog(context);
progressDialog.setTitle("Loading...");
progressDialog.setMessage("Please wait.");
//progressDialog.setCancelable(false);
progressDialog.setIndeterminate(true);
progressDialog.show();
}
}
@Override
public void onPageFinished(WebView view, String url) {
isPageLoadedComplete = true;
// Page is done loading;
// hide the progress dialog and show the webview
if (progressDialog.isShowing()) {
progressDialog.dismiss();
progressDialog = null;
webView.setEnabled(true);
}
}
@Override
public void onReceivedSslError (WebView view, SslErrorHandler handler, SslError error) {
handler.proceed();
}
@Override
public void onReceivedError(WebView view, int errorCod,String description, String failingUrl) {
Toast.makeText(context, "Your Internet Connection May not be active Or " + description , Toast.LENGTH_LONG).show();
}
});
}
/**
*This class is invoke when you times up.
*/
class loaderTask extends TimerTask {
public void run() {
System.out.println("Times Up");
if(isPageLoadedComplete){
}else{
if (progressDialog.isShowing()) {
progressDialog.dismiss();
progressDialog = null;
webView.setEnabled(true);
}
//show error message as per you need.
}
}
}
