android 顯示pdf文件內容

先要對pdf文件進行解析，然後顯示出來 解析pdf文件需要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();    /**     * 設置文件的信息     */    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：   設置文件的信息  * 創建人：ANSJ     * 創建時間：2010-4-14 下午04:27:57    * 修改備注：     * @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;  } }
