How to Create and Display PDF File in Android

I have created one Demo for Creating and Displaying PDF file in Android.


Please follow steps to create Android Project.

I have given Java and XML code as following:

MainActivity.java

package com.example;

import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;

import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Color;
import android.net.Uri;
import android.os.Bundle;
import android.os.Environment;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

import com.lowagie.text.Document;
import com.lowagie.text.DocumentException;
import com.lowagie.text.Font;
import com.lowagie.text.HeaderFooter;
import com.lowagie.text.Image;
import com.lowagie.text.Paragraph;
import com.lowagie.text.Phrase;
import com.lowagie.text.pdf.PdfWriter;

public class MainActivity extends Activity {

private Button createPDF , openPDF;

@Override
protected void onCreate(Bundle savedInstanceState) 
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

createPDF = (Button)findViewById(R.id.button1);
createPDF.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
createPDF();
}
});
openPDF = (Button)findViewById(R.id.button2);
openPDF.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
openPdf();
}
});
}

public void createPDF()
{
Document doc = new Document();

try {
String path = Environment.getExternalStorageDirectory().getAbsolutePath() + “/PDF”;

File dir = new File(path);
if(!dir.exists())
dir.mkdirs();

Log.d(“PDFCreator”, “PDF Path: ” + path);

File file = new File(dir, “demo.pdf”);
FileOutputStream fOut = new FileOutputStream(file);

PdfWriter.getInstance(doc, fOut);

//open the document
doc.open();

/* Create Paragraph and Set Font */
Paragraph p1 = new Paragraph(“Hi! I am Generating my first PDF using DroidText”);
/* Create Set Font and its Size */
Font paraFont= new Font(Font.HELVETICA);
paraFont.setSize(16);
p1.setAlignment(Paragraph.ALIGN_CENTER);
p1.setFont(paraFont);

//add paragraph to document    
doc.add(p1);

Paragraph p2 = new Paragraph(“This is an example of a simple paragraph”);
/* You can also SET FONT and SIZE like this */
Font paraFont2= new Font(Font.COURIER,14.0f,Color.GREEN);
p2.setAlignment(Paragraph.ALIGN_CENTER);
p2.setFont(paraFont2);

doc.add(p2);

/* Inserting Image in PDF */
ByteArrayOutputStream stream = new ByteArrayOutputStream();
Bitmap bitmap = BitmapFactory.decodeResource(getBaseContext().getResources(), R.drawable.android);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100 , stream);
Image myImg = Image.getInstance(stream.toByteArray());
myImg.setAlignment(Image.MIDDLE);

//add image to document
doc.add(myImg);

//set footer
Phrase footerText = new Phrase(“This is an example of a footer”);
HeaderFooter pdfFooter = new HeaderFooter(footerText, false);
doc.setFooter(pdfFooter);

Toast.makeText(getApplicationContext(), “Created…”, Toast.LENGTH_LONG).show();
} catch (DocumentException de) {
Log.e(“PDFCreator”, “DocumentException:” + de);
} catch (IOException e) {
Log.e(“PDFCreator”, “ioException:” + e);
finally
{
doc.close();
}
}      
void openPdf()
{
Intent intent = new Intent(Intent.ACTION_VIEW);
String path = Environment.getExternalStorageDirectory().getAbsolutePath() + “/PDF”;

File file = new File(path, “demo.pdf”);
intent.setDataAndType( Uri.fromFile( file ), “application/pdf” );
   startActivity(intent);
}
}


activity_main.xml

<RelativeLayout xmlns:android=”http://schemas.android.com/apk/res/android”
