Display sqlite database content in pdf format in android

Question

I have a Sqlite database in Android and I want to display its content in a PDF file, by building it dynamically in Android on pressing a Button.

I am aware with iText but I want to go with a simpler solution.. Can anyone help me with it plz!!

Answer 1

Look at droidtext which a port of the iText library version 2.1.7 for Android.

There are lots of examples too. Get started with Helloworld.

public class HelloWorld {

        /**
         * Generates a PDF file with the text 'Hello World'
         * 
         * @param args
         *            no arguments needed here
         */
        public static void main(String[] args) {

                System.out.println("Hello World");

                // step 1: creation of a document-object
                Document document = new Document();
                try {
                        // step 2:
                        // we create a writer that listens to the document
                        // and directs a PDF-stream to a file
                        PdfWriter.getInstance(document, new FileOutputStream(android.os.Environment.getExternalStorageDirectory() + java.io.File.separator + "droidtext" + java.io.File.separator + "HelloWorld.pdf"));

                        // step 3: we open the document
                        document.open();
                        // step 4: we add a paragraph to the document
                        document.add(new Paragraph("Hello World"));
                } catch (DocumentException de) {
                        System.err.println(de.getMessage());
                } catch (IOException ioe) {
                        System.err.println(ioe.getMessage());
                }

                // step 5: we close the document
                document.close();
        }
}

For display content of Sqlite database into pdf you have to use itextpdf-5.2.1.jar.you can download it from here

Example code:

DatabaseHandlerofdatabase   dbHandler = new DatabaseHandlerofdatabase(this);

    SQLiteDatabase db = dbHandler.getWritableDatabase();

    Cursor c1 = db.rawQuery("SELECT * FROM tablename", null);

    String filename="nameoffile.pdf";

     Document document=new Document();  // create the document
     File root = new File(Environment.getExternalStorageDirectory(), "Notes"); 
     if (!root.exists()) {
         root.mkdirs();   // create root directory in sdcard
     }
     File gpxfile = new File(root,filename);  // generate pdf file in that directory
     PdfWriter.getInstance(document,new FileOutputStream(gpxfile));
     document.open();  // open the directory


     Paragraph p3=new Paragraph();  // to enter value you have to create paragraph  and add value in it then paragraph is added into document
     p3.add("Username : ");
     document.add(p3);


    // now for ad table in pdf use below code



     PdfPTable table = new PdfPTable(3); // Code 1

    // Code 2
     table.addCell("CATEGORY");
     table.addCell("BUDGET");
     table.addCell("USED BUDGET");

   // now fetch data from database and display it in pdf

    while (c1.moveToNext()) {



    // get the value from database


        String ex_bdgt = c1.getString(3);
        String used_bdgt = c1.getString(5);


         table.addCell(type);
         table.addCell(ex_bdgt);
         table.addCell(used_bdgt);



        int temp_ex=Integer.parseInt(ex_bdgt);
        ttlbud=ttlbud+temp_ex;
        int temp_used=Integer.parseInt(used_bdgt);
        usdbud=usdbud+temp_used;



    }



    // add table into document

    document.add(table);    
    document.addCreationDate();
      document.close();
