Capture full webView in android

I am unable to capture complete WebView, I'm capturing only visible content of Dashboard(Activity). My WebView is exceeding the activity. Guide me how to capture complete view.

webView.setWebViewClient(new WebViewClient() {

    public void onPageFinished(WebView v, String url) {
        webView.setDrawingCacheEnabled(true);
        webView.buildDrawingCache();
        Bitmap bmp = Bitmap.createBitmap(webView.getWidth(), webView.getHeight(), Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(bmp);
        webView.draw(canvas);
        imgView.setImageBitmap(bmp);
    }
});
