How to get link-URL in Android WebView with HitTestResult for a linked image (and not the image-URL) with Longclick
None of solutions above worked for me on Android 4.2.2. So I looked into source code of default android web browser. I extracted solution to this exact problem - get link-URL from image link.
Source: https://github.com/android/platform_packages_apps_browser/blob/master/src/com/android/browser/Controller.java
Extracted solution:
LongClick listener:
...
mWebview.setOnLongClickListener(new OnLongClickListener() {
@Override
public boolean onLongClick(View v) {
HitTestResult result = mWebview.getHitTestResult();
if (result.getType() == HitTestResult.SRC_IMAGE_ANCHOR_TYPE) {
Message msg = mHandler.obtainMessage();
mWebview.requestFocusNodeHref(msg);
}
}
});
...
Handler to get the URL:
private Handler mHandler = new Handler() {
@Override
public void handleMessage(Message msg) {
// Get link-URL.
String url = (String) msg.getData().get("url");
// Do something with it.
if (url != null) ...
}
};
I know this is an old issue, but I recently came across this issue. Based on Perry_ml answer, I used the following Kotlin code to resolve it:
webView.setOnLongClickListener {
val result = webView.hitTestResult
if (result.type == WebView.HitTestResult.SRC_IMAGE_ANCHOR_TYPE) {
val handler = Handler()
val message = handler.obtainMessage()
webView.requestFocusNodeHref(message)
val url = message.data.getString("url")
// Do something with url, return true as touch has been handled
true
} else {
false
}
}
I posted some information about it here.
I checked the source code of the WebView and it seems that the image uri is the only extra data you can get for SRC_IMAGE_ANCHOR_TYPE. But don't be mad here I have a quick and dirty workaround for you:
webview.setOnLongClickListener(new OnLongClickListener() {
@Override
public boolean onLongClick(View v) {
final WebView webview = (WebView) v;
final HitTestResult result = webview.getHitTestResult();
if(result.getType()==HitTestResult.SRC_IMAGE_ANCHOR_TYPE) {
webview.setWebViewClient(new WebViewClient(){
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// 2. and here we get the url (remember to remove the WebView client and return true so that the hyperlink will not be really triggered)
mUrl = url; // mUrl is a member variant of the activity
view.setWebViewClient(null);
return true;
}
});
// 1. the picture must be focused, so we simulate a DPAD enter event to trigger the hyperlink
KeyEvent event1 = new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_DPAD_CENTER);
webview.dispatchKeyEvent(event1);
KeyEvent event2 = new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_DPAD_CENTER);
webview.dispatchKeyEvent(event2);
// 3. now you can do something with the anchor url (and then clear the mUrl for future usage)
String url = mUrl;
if (url!=null) {
Toast.makeText(webview.getContext(), url, Toast.LENGTH_SHORT).show();
}
mUrl = null;
}
return false;
}
});
I tried the code on a low-end Android 2.1 device and a high-end Android 4.0 device, both work like a charm.
