I have Android WebView which displays search results. Using the contextMenu and WebView HitTestResult, I have successfully implemented a list of options like open, save, copy link url.Now, I would like to implement copy link text feature as present in Google chrome android which should copy only link text (title). A similar(not exact) feature is present in default Android browser as "Select text" option. I don't want the code for copying text using clipboard instead my main motto is to determine the way of retrieving the link title. The link url can be retrieved using HitTestResult getExtra() method likewise is there any way to retrieve the link text (title) ?
I have referred How to get loaded web page title in Android WebView? but it gives title after the webpage is loaded not when the link is pressed.
Unfortunately, the link you posted is the fastest way to get the page title (you may refer to the second answer, which is probably faster).
The reason behind this is that a website needs to be loaded before you can read the page title. The advantage of onReceivedTitle() (the second answer of your link) is that it doesn't wait until the whole page is loaded. It waits until enough is loaded to retrieve the title from the document. It also notifies you every time the page title gets change (due to JavaScript or whatever).
Edit:
What chrome does with Copy link text is to copy the text of the link like this:
Linktext
This is very difficult to achieve via a webview, since you need access to the html-content of the webpage. There are some workarounds out there (see here).
The are two APIs (selectText and copySelection) which are pending API council approval, they would help you to do this, but they are not available at the moment.
A clear, official way to do this is not available.
For copy the text try this:-
if(android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.HONEYCOMB) {
android.text.ClipboardManager clipboard = (android.text.ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
clipboard.setText(mPostCode);
Toast.makeText(getApplicationContext(), "Your code is copied.", Toast.LENGTH_SHORT).show();
} else {
android.content.ClipboardManager clipboard = (android.content.ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
android.content.ClipData clip = android.content.ClipData.newPlainText("Copied Text", mPostCode);
clipboard.setPrimaryClip(clip);
}

Case: User should be able to view and print pdf
My solution: I am opening PDF inside Webview with the help of docs.google.com/gview. Below is my code
Set up Webview
string url = "http://www.africau.edu/images/default/sample.pdf";
string gview = $"https://docs.google.com/gview?embedded=true&url={url}";
mWebView.LoadUrl(gview);
Print PDF
var printMgr = (PrintManager)GetSystemService(PrintService);
printMgr.Print("print", mWebView.CreatePrintDocumentAdapter("print"), null);
Below is the screenshot. As you can see PDF loads just fine
Problem
When I want to print PDF, all the PDF pages are printed in one paper which you can see below
I would appreciate any suggestion, including different library for displaying/printing pdf or suggestion in Java or Kotlin, I can convert them to C#.
I would not print the web page but print the PDF directly as when printing the web page it just sees it as a longer web page and knows nothing about the content.
Use a custom print adapter instead, but instead of drawing a PDF to print you can just use the existing PDF you already have.
See for details https://developer.android.com/training/printing/custom-docs.html
I'm preparing an application it's 50% Native 50% Webview. Some users doesn't know how to paste from clipboard on mobile that's why I wanna make an button and user when click this button, it's must paste from clipboard to input. Javascript or Android or PHP I need.
Can you help me about it?
CharSequence pasteData="";
ClipData.Item item = clipboard.getPrimaryClip().getItemAt(0);
pasteData = item.getText();
Then use the pasteData.
As you want to give it to the web, use the message transport from java to javascript. See this: How to call javascript from Android?
Then you only need to send the pasteData to js, use js to change the data of the input.

I am trying to open email activity and to display in the email's body the following:
Display a hyperlink to a web site.
Display (not attach) an image logo (.png file).
I tried using html/text/image mime type and nothing works for both things.
I even tried to copy the png file to an sdcard and displaying it from sdcard path instead of using the "Assets" location that may be restricted and private only to the application, but it did not help as well!
Can anyone give me a code which works for both things??
Waiting for you help guys!!
Have you tried :
Linkify.addLinks(yourEmailString, Linkify.WEB_URLS);
yourTextView.setMovementMethod(LinkMovementMethod.getInstance());
It will make all links in the message clickable, not sure if this is what you are searching though :)?
I take the response from an HTTP connection in the form of string and show that to webview like this:
WebView engine = (WebView)findViewById(R.id.webview);
engine.loadData(endResult, "text/html", "UTF-8"); /*endresult is string*/
I actually get a response that contains the google page (google search result direct from google.com).
The loadData method works well i.e it shows the web page but when I click on one of the links on that page it shows "page not available" and said that "xyz link might be temporarily down or it may have moved to permanently to a new web address".
this happens for all links accept the first present link on that page. i.e it shows correct page from first link on that page but fails for others..
I noticed that OSes prior to 2.3 failed to follow links if setHorizontalScrollBarEnabled and setVerticalScrollBarEnabled are set to false.
try to use loadDataWithBaseURL of the WebView class
I would avoid using engine.loadData - it seems to cause all sorts of crazy problems.
Use engine.loadDataWithBaseURL instead, and pass the base URL of where the content exists. I would think that the content you are loading is using relative paths in it's HTML so it's looking inside your app resources. By specifying the base URL you get around this problem.
If a page has a URL or a phone number on it that isn't a link is there any way to have WebView recognize it and automatically turn it into a link like you can with TextViews?
With a TextView you would simply set the android:autoLink to the desired settings:
<TextView
android:autoLink="web|phone"
... />
but I can't find any equivalent for WebView.
If you are loading your own (web) content from a String, then you can do something like this:
final String content = "My email is: firstname#email.com ...";
Spannable sp = new SpannableString(content);
Linkify.addLinks(sp, Linkify.ALL);
final String html = "<body>" + Html.toHtml(sp) + "</body>";
myWebView.loadData(html, "text/html", "utf-8");
I don't know about any way which would make this work just by changing a setting, but a workaround would be to wait until the web page finishes loading and then do:
yourWebView.loadUrl("javascript:(function(){ /* code that creates links */ })()");
This will inject javaScript into the already loaded web page.
There's a slightly longer example available here: http://lexandera.com/2009/01/injecting-javascript-into-a-webview/.
You can find the JavaScript source for creating links if you take a look at the source of Linkify script for Greasemonkey (it's a plugin for Firefox in case you're not familiar with it). I believe it comes with the default install.
