If an img tag load failed in webview,it shows a "?" in blue background color.
How can I replace the default img or hide it in Android Code?
I want to hide it in Android Code, because in javascript, I can use onerror or onload events to solve the problem, but in that way, I have to bind events to all img tag, so I want to find a way in Android Code. I guess webview may have some setting or event to do it, but I don't know.
Check this code it may guide you to a solution:
webView.setWebViewClient(new WebViewClient(){
#TargetApi(11)
#Override
public WebResourceResponse shouldInterceptRequest(WebView view, String url) {
return super.shouldInterceptRequest(view, url);
}
};

How to go EXACTLY to http://example.com/index.html#label if content to webview loading via WebView.loadDataWithBaseURL ?
By default webview go to root only. How go to label ?
WebView doesn't have such functionality from the box.
You can achieve this with the help of javascript, but this is a bit of ugly.
You should load your html page and then add javascript code to it.
After this you can load your webview and call javascript methods from current page.
Check this link for example how that can be done.
WebView jump to anchor using loadDataWithBaseUrl
Example goes here
webContents.setWebViewClient(new WebViewClient(){
#Override
public void onPageFinished(WebView view, String url) {
String id = "895884";
webContents.loadUrl("javascript:scrollAnchor(" + id + ");");
}
});
I have loaded a WebView in my android app:
webView = (WebView)view.findViewById(R.id.webView);
String url = UrlConstants.URL_CITY;
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl(url);
webView.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
But every popUp that is of the website has a transparent background as shown:
I've tried many urls as well: One being this
Anyone help will be appreciated. Thanks
I had a similar issue when adding WebView at runtime using addView. Turns out you need to use the addView overload specifying LayoutParams with MATCH_PARENT. Failing to do so would break side menus and pop-up on some web pages. Really nasty bug if you ask me.
I am working on one Android App where I am loading local file contents into webview using following syntax.
url = "file://" + mLocalFilePath + java.io.File.separator + CURRENT_FILE;
webView.loadUrl(url);
The issue is the webview loads file contents and also loads the various images from url present in webpage ( webpage has many images ).
The challenge I am facing is I want to get notified when webview finish rendering entire html page.I want to get notified when webpage is 100% loaded.
I reffered various forums and also tried using
window.onload function
as well as
public void onPageFinished(WebView view, String url)
But I did not get desire output,I get callback before html page is completely loaded.I am looking for way so that I will get notified only when webpage has finished rendering all the images present in web page.( i.e Webpage is 100% loaded.)
I am not looking for complete answer even hints will be appreciated.
Thanks
Try this way
webView.setWebChromeClient(new WebChromeClient(){
#Override
public void onProgressChanged(WebView view, int newProgress) {
super.onProgressChanged(view, newProgress);
if(newProgress==100){
// page loading completes
}
}
});
I used deprecated PictureListener that start when all images on the pages are loaded. It deprecated and you need at least one image in the html but if you can manage this (you could place transparent 1px*1px image) it's a good solution.
wv.setPictureListener(new PictureListener() {
#Override
public void onNewPicture(WebView view, Picture picture) {
// some code here
}
}
});
When I type the url in the text box and click on the Go button the webview loads the required page but when I click on any link inside the webview the address bar which is the text box is not updated with the exact url? How do I go about doing this?
I am trying all varies ways on google not getting the solution - probably key words are wrong. :( - Help on this would be great.
Thanks!
You need to Override onPageFinished method
#Override
public void onPageFinished(WebView view, String url) {
urlEditText.setText(url, TextView.BufferType.NORMAL);
super.onPageFinished(view, url);
}
I'm using standard addresses like google and facebook, but loadUrl does nothing, it just sits there at a white screen, but if i pipe html into it using loadData, it works fine. Any ideas or tips? I've got it enabling javascript, and I have this call:
mWebView.setWebViewClient(new WebViewClient() {
#Override
public void onPageFinished(WebView view, String url) {
TextView t;
t = (TextView)findViewById(R.id.pageTitle);
t.setText(view.getTitle());
}
});
Do i need to override anyhting else?
Check whether you have enabled INTERNET permission in Android manifest file.
