Using CPDFReaderView

The ComPDF SDK provides the CPDFReaderView component for viewing and editing PDF documents in Android applications. This section describes how to add this view to a layout and initialize it.

1. Add CPDFReaderView to the XML layout

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <!-- Create a CPDFReaderView -->
    <com.compdfkit.ui.reader.CPDFReaderView
        android:id="@+id/readerview"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</androidx.constraintlayout.widget.ConstraintLayout>

1. Obtain and initialize the view in code

// Get CPDFReaderView from XML
CPDFReaderView readerView = findViewById(R.id.readerview);

1. Open a PDF document

CPDFDocument document = new CPDFDocument(context);
PDFDocumentError error = document.open("filePath"); // file path or uri
if (error == PDFDocumentError.PDFDocumentErrorSuccess){
  // Bind the document to CPDFReaderView
  readerView.setPDFDocument(document);
}
