UI/UX android-pdfview

Overview

This project is no longer maintained.

You can find a good replacement here, which is a fork relying on Pdfium instead of Vudroid/MuPDF for decoding PDF files, allowing it to use the Apache License 2.0 which gives you much more freedom.

Android PDFView is a library which provides a fast PDFView component for Android, with animations, gestures, and zoom. It's based on VuDroid for decoding the PDF file.

Get it

Android PDFView is available in Maven Central.

<dependency>
	<groupId>com.joanzapata.pdfview</groupId>
	<artifactId>android-pdfview</artifactId>
	<version>1.0.4</version>
	<type>apklib</type>
</dependency>

Or via gradle:

compile 'com.joanzapata.pdfview:android-pdfview:1.0.4@aar'

Include PDFView in your layout

<com.joanzapata.pdfview.PDFView
        android:id="@+id/pdfview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

Load a PDF file

pdfView.fromAsset(pdfName)
    .pages(0, 2, 1, 3, 3, 3)
    .defaultPage(1)
    .showMinimap(false)
    .enableSwipe(true)
    .onDraw(onDrawListener)
    .onLoad(onLoadCompleteListener)
    .onPageChange(onPageChangeListener)
    .load();

pages is optional, it allows you to filter and order the pages of the PDF as you need
onDraw is also optional, and allows you to draw something on a provided canvas, above the current page

PDF rendering issues

Hi Joan,

first of all - thank you for this great library.

I have an issue with the PDF rendering when I zoom in.

Please take a look at the attached screenshot.

Do you have an idea why this problem occurs?

Set orientation of the pdf

Right now, some pdfs are displayed in portrait mode while the device is in landscape (see image). I guess this is due to the calculations (width height of a page). But this is pretty strange behaviour I think so it would be nice if there was an extra setting that forces all pages to be displayed horizontal or vertical.

So that the pages are readable in the same orientation the device is in..

I can't open a downloaded PDF on a Galaxy S3 Mini. It always causes the following exception:

I can't reproduce this error on my HTC One M8, I don't know how to fix it, but it seems that there's an error in your library. Would be nice if you can fix it! :)

Update PdfPage.java

Hey,

First of all, thanks a lot for that tremendous component you provided.

I ran into a regular crash when i was using the component to display various pdf file : on the left pane the name of the file and when the user click on a name, the pdf is displayed on the right.

Switching quickly between files to display led me into a RunTimeException in the function :

static PdfPage createPage(long dochandle, int pageno) { return new PdfPage(open(dochandle, pageno), dochandle); }

in org.vudroid.pdfdroid.codec.PdfPage

A little investigation led me to find that this happened when two threads was calling this function at the same time.

Just added a "synchronized" qualifier on the function and that bug was gone.

Slow rendering

Hello! I'm trying to use an amazing android-pdfview library in my app. However pdf rendering is veeery slow. Viewer shows a blank white screen about 2-4 sec and then starts to render: (device: Nexus 7 first generation). Pdf has only 1 page but it remains unreadable during several seconds while viewer is slowly making the document readable by square zones. Yes, finally pdf is readable, but it takes more than 10-15 seconds - totally user-unfriendly. Is it common problem? How could I accelerate rendering?

Add ability by call PDFView.recycle(), recycle for all instances of pdfview

For example if I want to use pdfView in viewPager. I should tracked that that pdfView on previous page was recycled, before showing pdf on current page.

What is minimap?

Hello, I wanted to ask what is minimap showing? Because I don't see any difference when the flag is either true of false. I need to make a view, where the thumbnails of all pages in pdf will be shown, and you can jump to any of them on click. I thought minimap will show me all that pages, but for now I don't understand what is it doing at all.
