screenshot from webview

I'm trying to take a screenshot of content of my WebView. I creare a bitmap and then create canvas from this bitmap, then I call method drawPage(canvas) inside onPageFinished() (that is a callback from WebChromeClient), but inside onPageFinished() webView still hasn't loaded content, so I see just black page at first, and then I see previous pages(because when I call it second time previous pages are loaded to webView). How could I deal with this problem? I can solve it using hadlers with some del开发者_StackOverflow社区ay, but I think there should be better way to do this. Thanks for help.

I don't think I understand the problem, but are you asking how to trigger an event on a WebView loading a page? Could you create a WebView client and override the onPageCompleted()?

private WebViewClient viewClient {
    @Override
    public boolean onPageFinished(WebView view, String url) {
        //here you can run your Bitmap creating code
        return true;
    }
}
YourWebView.setWebViewClient(viewClient);

Is this what your looking for?
