android 顯示pdf檔案內容

先要對pdf檔案進行解析，然後顯示出來解析pdf檔案需要pdfbox的jar包， 下面是解析pdf的代碼：package com.lingjoin.extractors;import java.io.BufferedReader;import java.io.FileNotFoundException;import java.io.IOException;import java.io.StringReader;import java.util.Date;import org.apache.pdfbox.pdmodel.PDDocument;import org.apache.pdfbox.pdmodel.PDDocumentInformation;import org.apache.pdfbox.util.PDFTextStripper;import com.lingjoin.paser.LingJoinFile;/** * PDF解析器 *  * @author Ansj *  */public class PDFExtractor extends AbstractExtractor {  private String getContent(LingJoinFile f) {  // TODO Auto-generated method stub  PDDocument doc = null ;  try {   doc = PDDocument.load(f);   PDFTextStripper stripper = new PDFTextStripper();   /**    * 設定檔案的資訊    */   this.setLingJoinFileInfo(f, doc     .getDocumentInformation());   return stripper.getText(doc);  } catch (FileNotFoundException e) {   // TODO Auto-generated catch block   e.printStackTrace();  } catch (IOException e) {   // TODO Auto-generated catch block   e.printStackTrace();  } finally {   if (doc != null) {    try {     doc.close();    } catch (IOException e) {     // TODO Auto-generated catch block     e.printStackTrace();    }   }  }  return ""; } private BufferedReader getContentReader(LingJoinFile f) {  return new BufferedReader(new StringReader(this.getContent(f))); } /** *     * 項目名稱：FilePaser  * 類描述：   設定檔案的資訊 * 建立人：ANSJ    * 建立時間：2010-4-14 下午04:27:57   * 修改備忘：    * @version      */ private void setLingJoinFileInfo(LingJoinFile f, PDDocumentInformation info) {  if (info.getAuthor() != null) {   f.setlAuthor(info.getAuthor());  } } public void paserFileToReader(LingJoinFile f) throws Exception {  f.setlContentReader(this.getContentReader(f)) ; } public void paserFileToString(LingJoinFile f) throws Exception {  // TODO Auto-generated method stub  f.setlContent(this.getContent(f)) ; }  public PDFExtractor(Integer typeFlag) {  // TODO Auto-generated constructor stub  this.typeFlag = typeFlag ; }  private Integer typeFlag = null ;  public Integer getTypeFlag() {  // TODO Auto-generated method stub  return typeFlag; }}
