How to create PDF from webview in android?

Question

I am displaying webpage in webview. Now how to create PDF from webview ?

For Example : webview loads URL is \"www.g

Answer 1

Try like this

WebView have inbuilt method called setPictureListener Use that method as below

webView1.setPictureListener(new PictureListener() {

            public void onNewPicture(WebView view, Picture picture) {
                if (picture != null) {
                    try {
                        bmp = pictureDrawable2Bitmap(new PictureDrawable(
                                picture));

                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                }
            }
        });

For obtaining bitmap i have used pictureDrawable2Bitmap and here is that one

private static Bitmap pictureDrawable2Bitmap(PictureDrawable pictureDrawable) {
        Bitmap bitmap = Bitmap.createBitmap(
                pictureDrawable.getIntrinsicWidth(),
                pictureDrawable.getIntrinsicHeight(), Config.ARGB_8888);
        Canvas canvas = new Canvas(bitmap);
        canvas.drawPicture(pictureDrawable.getPicture());
        return bitmap;
    }

Now Your Bitmap is ready,Now set webview client as below

webView1.setWebViewClient(new myWebClient());

And here is myWebClient

public class myWebClient extends WebViewClient {
        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            // TODO Auto-generated method stub
            super.onPageStarted(view, url, favicon);
        }

        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            // TODO Auto-generated method stub

            view.loadUrl(url);
            return true;

        }

        @Override
        public void onPageFinished(WebView view, String url) {
            // TODO Auto-generated method stub
            super.onPageFinished(view, url);
            Log.i("OnPageLoadFinished", url);
            img.setImageBitmap(bmp);
        }

As shown on page load finished i have set image bitmap which is snap of current loaded url on your webview

Now Bitmap is ready pass that bitmap to Pdf using IText Library

Here is an example of writing pdf with image on iText Use Below function for that

public void SimplePDFTable() throws Exception {

    File direct = new File(Environment.getExternalStorageDirectory()
            .getAbsolutePath() + "/AamirPDF");
    if (!direct.exists()) {
        if (direct.mkdir()) {
            Toast.makeText(MainActivity.this,
                    "Folder Is created in sd card", Toast.LENGTH_SHORT)
                    .show();
        }
    }
    String test = Environment.getExternalStorageDirectory()
            .getAbsolutePath() + "/AamirPDF";
    Document document = new Document();

    PdfWriter.getInstance(document, new FileOutputStream(test
            + "/mypdf.pdf"));

    document.open();
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
    byte[] byteArray = stream.toByteArray();
    Image image = Image.getInstance(byteArray);


    image.scaleToFit(PageSize.A4.getHeight(), PageSize.A4.getWidth());
    document.add(image);

    document.close();

}

Good Luck
