Android: overriding shouldOverrideUrlLoading not working on HTC devices

问题

On a HTC Evo running Android 2.3.5, overrriden shouldOverrideUrlLoading() is never called. The exact same code works well on a Samsung Galaxy running Android 2.3.6.

so far, I have tried overriding onPageStarted() and onPageFinished(). I do not see the URL in these methods.

My intent is to provide custom activities for mailto: and tel: links present in the page. Any ideas on how I can make this work if shouldOverrideUrlLoading() is never hit?

I have already looked at similar questions on stackoverflow and elsewhere, haven't found anything relevant.

回答1:

shouldOverrideUrlLoading() doesn't work only on some Android versions, like 2.1 or 2.3.6 but it works fine on 2.3.3, 2.3.5, 4.0.2 or 4.0.3.

If you need to handle clicking on a link on webview, you must use shouldOverrideUrlLoading() method. If you only need to handle loading a webpage, you should use onPageStarted().

This is android developer link: https://developer.android.com/guide/webapps/migrating.html

Note: Ex: we have 2 links on Webpage.
1. <a href="http://www.w3schools.com/">Visit W3Schools!</a>
2. <a href="http://www.w3schools.com/" target="_blank">Visit W3Schools!</a>

shouldOverrideUrlLoading() is only called when user click on link "1". and it isn't called when user click on link "2"

public void onPageStarted(WebView view, String url, Bitmap favicon) {

    if (url.contains("success")) {
        Intent intent = new Intent(WebviewActivity.this, OrderConfirmActivity.class);
        intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        startActivity(intent);
    } else {
        super.onPageStarted(view, url, favicon);
    }
}
