Android中解析读取复杂word，excel，ppt等的方法

        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;
}
}

        效果图如下：

       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());
}
i = temp;
} else {
output.write(tagBegin.getBytes());
writeParagraphContent(p);
output.write(tagEnd.getBytes());
}
}
String end = "</body></html>";
output.write(end.getBytes());
output.close();
} catch (Exception e) {

e.printStackTrace();
}
}
