PictureListener is deprecated and obsolete, is there a replacement?

问题

I would like to be notified when an image has been completely draw on the WebView. Using PictureListener and onNewPicture is a common answer (even suggested by the onPageFinished documentation) to this but is listed as deprecated and obsolete. Is there a replacement/alternative?

回答1:

I see with Android 4.0 the doc was updated:

This method is deprecated. Due to internal changes, the picture does not include composited layers such as fixed position elements or scrollable divs. While the PictureListener API can still be used to detect changes in the WebView content, you are advised against its usage until a replacement is provided in a future Android release.

There is no replacement yet.

how about

webview.setWebViewClient(new WebViewClient(){

    @Override
    public void onPageFinished(WebView view, String url) {
        // you can get the picture here
        super.onPageFinished(view, url);

    }
});
