Package com.github.barteksc.pdfviewer

Class PDFView

java.lang.Object

android.view.View

android.view.ViewGroup

android.widget.RelativeLayout

com.github.barteksc.pdfviewer.PDFView

All Implemented Interfaces:

android.graphics.drawable.Drawable.Callback, android.view.accessibility.AccessibilityEventSource, android.view.KeyEvent.Callback, android.view.ViewManager, android.view.ViewParent

public class PDFView
extends android.widget.RelativeLayout

It supports animations, zoom, cache, and swipe.

To fully understand this class you must know its principles : - The PDF document is seen as if we always want to draw all the pages. - The thing is that we only draw the visible parts. - All parts are the same size, this is because we can't interrupt a native page rendering, so we need these renderings to be as fast as possible, and be able to interrupt them as soon as we can. - The parts are loaded when the current offset or the current zoom level changes

Important : - DocumentPage = A page of the PDF document. - UserPage = A page as defined by the user. By default, they're the same. But the user can change the pages order using load(DocumentSource, String, int[]). In this particular case, a userPage of 5 can refer to a documentPage of 17.
