前段时间在尝试做一个Android里的万能播放器，能播放各种格式的软件，其中就涉及到了最常用的office软件。查阅了下资料，发现Android中最传统的直接解析读取word，excel的方法主要用了java里第三方包，比如利用tm-extractors-0.4.jar和jxl.jar等，下面附上代码和效果图。

读取word用了tm-extractors-0.4.jar包，代码如下：

package com.example.readword;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;

import org.textmining.text.extraction.WordExtractor;

import android.app.Activity;
import android.os.Bundle;
import android.os.Environment;
import android.widget.TextView;


public class MainActivity extends Activity {
    /** Called when the activity is first created. */

    private TextView text;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        text = (TextView) findViewById(R.id.text);

        String str = readWord("/storage/emulated/0/ArcGIS/localtilelayer/11.doc");
        text.setText(str.trim().replace("", ""));
    }

    public String readWord(String file){
        //创建输入流用来读取doc文件
        FileInputStream in;
        String text = null;
        try {
            in = new FileInputStream(new File(file));
            WordExtractor extractor = null;
            //创建WordExtractor
            extractor = new WordExtractor();
            //进行提取对doc文件
            text = extractor.extractText(in);
        }
        catch (FileNotFoundException e) {
            e.printStackTrace();
        }
        catch (Exception e) {
            e.printStackTrace();
        }
        return text;
    }
}

只是从网上随便下载的一个文档，我们可以看出，虽然能读取，但是格式的效果并不佳，而且只能读取doc，不能读取docx格式，也不能读取doc里的图片。另外就是加入使用WPF打开过这个doc的话，将无法再次读取（对于只安装WPF的我简直是个灾难）

然后是用jxl读取excel的代码，这个代码不是很齐，就写了个解析的，将excel里每行每列都解析了出来，然后自己可以重新再编辑，代码如下：

package com.readexl;

import java.io.FileInputStream;
import java.io.InputStream;

import android.os.Bundle;
import android.os.Environment;
import android.app.Activity;
import android.text.method.ScrollingMovementMethod;
import android.view.Menu;
import android.widget.TextView;

import jxl.*;

public class MainActivity extends Activity {
    TextView txt = null;
    public String filePath_xls = Environment.getExternalStorageDirectory()
            + "/case.xls";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        txt = (TextView)findViewById(R.id.txt_show);
        txt.setMovementMethod(ScrollingMovementMethod.getInstance());
        readExcel();
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    public void readExcel() {
        try {
            /**
             * 后续考虑问题,比如Excel里面的图片以及其他数据类型的读取
             **/

            InputStream is = new FileInputStream(filePath_xls);
            //Workbook book = Workbook.getWorkbook(new File("mnt/sdcard/test.xls"));
            Workbook book = Workbook.getWorkbook(is);

            int num = book.getNumberOfSheets();
            txt.setText("the num of sheets is " + num+ "\n");
            // 获得第一个工作表对象
            Sheet sheet = book.getSheet(0);
            int Rows = sheet.getRows();
            int Cols = sheet.getColumns();
            txt.append("the name of sheet is " + sheet.getName() + "\n");
            txt.append("total rows is " + Rows + "\n");
            txt.append("total cols is " + Cols + "\n");
            for (int i = 0; i < Cols; ++i) {
                for (int j = 0; j < Rows; ++j) {
                    // getCell(Col,Row)获得单元格的值
                    txt.append("contents:" + sheet.getCell(i,j).getContents() + "\n");
                }
            }
            book.close();
        } catch (Exception e) {
            System.out.println(e);
        }
    }

}

效果图如下：

好吧，这只是个半成品，不过，这个方法肯定是行得通的。

之前说了这么多，很明白的意思就是我对于这两种方法都不是很满意。在这里，我先说下doc和docx的区别（xls和xlsx，ppt和pptx等区别都和此类似）

众所周知的是doc是03及之前版本word所保存的格式，docx是07版本之后保存的格式，简单的说，在doc中，微软还是用二进制存储方式；在docx中微软开始用xml方式，docx实际上成了一个打包的ZIP压缩文件。doc解压得到的是没有扩展名的文件碎片，而docx解压可以得到一个XML和几个包含信息的文件夹。两者比较的结论就是docx更小，而且要读取图片更容易。（参考http://www.zhihu.com/question/21547795）

好吧，回到正题。如何才能解析各种word，excel等能保留原来格式并且解析里面的图片，表格或附件等内容呢。那当然就是html了！不得不承认html对于页面，表格等展示的效果确是是很强大的，原生很难写出这样的效果。在网上找了诸多的资料，以及各个大神的代码，自己又再此基础上修改了下，实现的效果还不错吧。

利用的包是POI（一堆很强大的包，可以解析几乎所有的office软件，这里以doc，docx，xls，xlsx为例）

读取文件后根据不同文件类型分别进行操作。

public void read() {
    if(!myFile.exists()){
        if (this.nameStr.endsWith(".doc")) {
            this.getRange();
            this.makeFile();
            this.readDOC();
        }
        if (this.nameStr.endsWith(".docx")) {
            this.makeFile();
            this.readDOCX();
        }
        if (this.nameStr.endsWith(".xls")) {
            try {
                this.makeFile();
                this.readXLS();
            } catch (Exception e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
        if (this.nameStr.endsWith(".xlsx")) {
            try{
                this.makeFile();
                this.readXLSX();
            }catch (Exception e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }
    returnPath = "file:///" + myFile;
    // this.view.loadUrl("file:///" + this.htmlPath);
    System.out.println("htmlPath" + this.htmlPath);

}

先贴上公用的方法，主要是设置生成的html文件保存地址：

public void makeFile() {
    String sdStateString = android.os.Environment.getExternalStorageState();// 获取外部存储状态
    if (sdStateString.equals(android.os.Environment.MEDIA_MOUNTED)) {// 确认sd卡存在,原理不知,媒体安装??
        try {
            File sdFile = android.os.Environment
                    .getExternalStorageDirectory();// 获取扩展设备的文件目录
            String path = sdFile.getAbsolutePath() + File.separator
                    + "library";// 得到sd卡(扩展设备)的绝对路径+"/"+xiao
            File dirFile = new File(path);// 获取xiao文件夹地址
            if (!dirFile.exists()) {// 如果不存在
                dirFile.mkdir();// 创建目录
            }
            File myFile = new File(path + File.separator +filename+ ".html");// 获取my.html的地址
            if (!myFile.exists()) {// 如果不存在
                myFile.createNewFile();// 创建文件
            }
            this.htmlPath = myFile.getAbsolutePath();// 返回路径
        } catch (Exception e) {
        }
    }
}

然后是读取doc：

private void getRange() {
    FileInputStream in = null;
    POIFSFileSystem pfs = null;

    try {
        in = new FileInputStream(nameStr);
        pfs = new POIFSFileSystem(in);
        hwpf = new HWPFDocument(pfs);
    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    range = hwpf.getRange();

    pictures = hwpf.getPicturesTable().getAllPictures();

    tableIterator = new TableIterator(range);

}

public void readDOC() {

    try {
        myFile = new File(htmlPath);
        output = new FileOutputStream(myFile);
        presentPicture=0;
        String head = "<html><meta charset=\"utf-8\"><body>";
        String tagBegin = "<p>";
        String tagEnd = "</p>";
        output.write(head.getBytes());
        int numParagraphs = range.numParagraphs();// 得到页面所有的段落数
        for (int i = 0; i < numParagraphs; i++) { // 遍历段落数
            Paragraph p = range.getParagraph(i); // 得到文档中的每一个段落
            if (p.isInTable()) {
                int temp = i;
                if (tableIterator.hasNext()) {
                    String tableBegin = "<table style=\"border-collapse:collapse\" border=1 bordercolor=\"black\">";
                    String tableEnd = "</table>";
                    String rowBegin = "<tr>";
                    String rowEnd = "</tr>";
                    String colBegin = "<td>";
                    String colEnd = "</td>";
                    Table table = tableIterator.next();
                    output.write(tableBegin.getBytes());
                    int rows = table.numRows();
                    for (int r = 0; r < rows; r++) {
                        output.write(rowBegin.getBytes());
                        TableRow row = table.getRow(r);
                        int cols = row.numCells();
                        int rowNumParagraphs = row.numParagraphs();
                        int colsNumParagraphs = 0;
                        for (int c = 0; c < cols; c++) {
                            output.write(colBegin.getBytes());
                            TableCell cell = row.getCell(c);
                            int max = temp + cell.numParagraphs();
                            colsNumParagraphs = colsNumParagraphs
                                    + cell.numParagraphs();
                            for (int cp = temp; cp < max; cp++) {
                                Paragraph p1 = range.getParagraph(cp);
                                output.write(tagBegin.getBytes());
                                writeParagraphContent(p1);
                                output.write(tagEnd.getBytes());
                                temp++;
                            }
                            output.write(colEnd.getBytes());
                        }
                        int max1 = temp + rowNumParagraphs;
                        for (int m = temp + colsNumParagraphs; m < max1; m++) {
                            temp++;
                        }
                        output.write(rowEnd.getBytes());
                    }
                    output.write(tableEnd.getBytes());

            }
        }
        String end = "</body></html>";
        output.write(end.getBytes());
        output.close();
    } catch (Exception e) {

        System.out.println("readAndWrite Exception:"+e.getMessage());

}

读取docx

public void readDOCX() {
