Generating 1D barcodes with android

Hey, There's a lot of pos开发者_Python百科ts on here about read barcodes but I want to generate barcodes from a string of numbers and display the generated barcode to the user in my application. I've had a look at a few libraries iTextPdf and Barbecue, in particular I've been trying to work with iTextPdf

I wondered if anyone knows of or could provide a simple implementation or suggest something better....

I want to draw the barcode directly to a custom view for display in a linear layout with other controls.

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Barcode128 code128 = new Barcode128();
    code128.setCodeType(Barcode128.CODE128);
    code128.setCode("123456789");
    Image image128 = code128.createTemplateWithBarcode(barcodeview, null, null);
}

For starters this errors and the app wont actually run, but I don't know how to draw this on to the layout.

This gives the following error

Thanks for your help.

Based on your stack trace, iTextPDF is not compatible with Android without at least a recompile, and probably more substantial changes than that. Bear in mind that there is a separate project for iTextPDF for Android -- I do not know if that is what you were using.
