android打开office资源
我们都知道安卓打开office资源可以用浏览器打开，但是需要翻墙，而iOS打开只需要自带的webview就能打开。真是坑人啊
我找了半天找到poi，然后自己改了下，实现了office资源的展示。下面就为大家来介绍我的思路
工具：eclipse，android-poi.jar
1 .android打开doc资源思路：把下载下来的doc文档转化为webview支持的html文件，用webview打开
步骤：先下载资源到sd卡里面，拿到路径。可能用到的类有
import org.apache.poi.hwpf.HWPFDocument;
import org.apache.poi.hwpf.converter.PicturesManager;
import org.apache.poi.hwpf.converter.WordToHtmlConverter;
import org.apache.poi.hwpf.usermodel.Picture;
import org.apache.poi.hwpf.usermodel.PictureType;
import org.w3c.dom.Document;
这么几个poi的类拿到文件路径，用下面的方法
public void convert2Html(String fileName, String outPutFile)throws TransformerException, IOException,ParserConfigurationException,OutOfMemoryError{HWPFDocument wordDocument = new HWPFDocument(new FileInputStream(fileName));WordToHtmlConverter wordToHtmlConverter = new WordToHtmlConverter(DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument());// 设置图片路径wordToHtmlConverter.setPicturesManager(new PicturesManager() {public String savePicture(byte[] content, PictureType pictureType,String suggestedName, float widthInches, float heightInches) {// 相对html路径return suggestedName;}});// 保存图片List<Picture> pics = wordDocument.getPicturesTable().getAllPictures();File file1 = new File(savePath);if (pics != null) {for (int i = 0; i < pics.size(); i++) {Picture pic = (Picture) pics.get(i);try {pic.writeImageContent(new FileOutputStream(new File(file1.getPath() + "/" + pic.suggestFullFileName())));} catch (FileNotFoundException e) {e.printStackTrace();}}}wordToHtmlConverter.processDocument(wordDocument);Document htmlDocument = wordToHtmlConverter.getDocument();ByteArrayOutputStream out = new ByteArrayOutputStream();DOMSource domSource = new DOMSource(htmlDocument);StreamResult streamResult = new StreamResult(out);TransformerFactory tf = TransformerFactory.newInstance();Transformer serializer = tf.newTransformer();serializer.setOutputProperty(OutputKeys.ENCODING, "utf-8");serializer.setOutputProperty(OutputKeys.INDENT, "yes");serializer.setOutputProperty(OutputKeys.METHOD, "html");serializer.transform(domSource, streamResult);out.close();// 保存html文件writeFile(new String(out.toByteArray()), outPutFile);}// 将html文件保存到sd卡public void writeFile(String content, String path) {FileOutputStream fos = null;BufferedWriter bw = null;try {File file = new File(path);if (!file.exists()) {file.createNewFile();}fos = new FileOutputStream(file);bw = new BufferedWriter(new OutputStreamWriter(fos, "utf-8"));bw.write(content);} catch (FileNotFoundException fnfe) {fnfe.printStackTrace();} catch (IOException ioe) {ioe.printStackTrace();} finally {try {if (bw != null)bw.close();if (fos != null)fos.close();} catch (IOException ie) {}}}// WebView加载显示本地html文件
webView.loadUrl("file://" + savePath + docName + ".html");
现在这个方法支持doc文件，docx文件不支持，还没找到方法。
2.打开ppt文件（这个功能可能有点简单，只是单纯的展示作用）
思路：ppt文件－－转化为多张图片－－用webview来展示（原因：由于功能需求：做成展示功能，所以ppt里面的东西不能点击，播放声音）
用到的poi的类有
import org.apache.poi.hslf.model.Slide;
import org.apache.poi.hslf.usermodel.SlideShow;
将ppt转换为图片
初始化slide和slideshow
//path文件路径
ppt = new SlideShow(new File(path));
//ppt总页数pgsize = ppt.getPageSize();slide = ppt.getSlides();slideCount = slide.length;转化png
/*** 生成图片*/private void addImageView(final int pos) {final Bitmap bmp = Bitmap.createBitmap((int) pgsize.getWidth(), (int) pgsize.getHeight(), Config.RGB_565);Canvas canvas = new Canvas(bmp);Paint paint = new Paint();paint.setColor(android.graphics.Color.WHITE);paint.setFlags(Paint.ANTI_ALIAS_FLAG);canvas.drawPaint(paint);final Graphics2D graphics2d = new Graphics2D(canvas);final AtomicBoolean isCanceled = new AtomicBoolean(false);// renderThread runnable = new Thread() {@Overridepublic void run() {try {if(slide==null){return;}slide[pos].draw(graphics2d, isCanceled, handler, pos);Message msg = handler.obtainMessage();// msg.obj = imageView;// imageView.setTag(bmp);write(Bitmap2Bytes(bmp), pos);msg.what = 3;msg.arg1 = pos;handler.sendMessage(msg);if(bmp!=null&&!bmp.isRecycled()){bmp.recycle();}} catch (Exception e) {Message msg = handler.obtainMessage();try {slide[pos + 1].draw(graphics2d, isCanceled, handler, pos);// msg.obj = imageView;// imageView.setTag(bmp);try {write(Bitmap2Bytes(bmp), pos + 1);} catch (IOException e1) {// TODO Auto-generated catch blocke1.printStackTrace();}msg.what = 3;msg.arg1 = pos + 1;handler.sendMessage(msg);if (bmp != null && !bmp.isRecycled()) {bmp.recycle();}} catch (Exception e2) {msg.what = 3;msg.arg1 = pos + 1;handler.sendMessage(msg);}} catch (OutOfMemoryError e) {// Toast.makeText(getActivity(), "打开异常，请重新打开",// Toast.LENGTH_LONG).show();System.gc();}}};runnable.start();}
这个poi有些图片会生成不出来，所以有时候就会缺失，但是大部分的ppt都是能够完整生成出来的。
最后图片在一个file里面，按生成的顺序，里面的排列也是按顺序来的，所以可以直接用webview展示
private void loadWebView() {File fiele = new File(pptPath);File[] files = fiele.listFiles();if (files.length != 0) {loadingdialog.dismiss();String data = "<html>" + "<body align=center>" +getImagesHtml(files) + "</body>" +"</html>";Log.e("网页html", data);mWebView.getSettings().setAllowFileAccess(true);mWebView.loadDataWithBaseURL("file://" + pptPath, data, "text/html", "UTF-8", null);}}private String getImagesHtml(File[] file) {String data = "";for (File file2 : file) {data += "<img" + " src=file://" + file2.getAbsolutePath() + " width=" + pgsize.getWidth() + " height="+ (pgsize.getHeight() + ScreenSizeUtil.Dp2Px(getActivity(), 48)) + " display:block; margin:0 auto;" + "><br/>";}return data;}
3.打开pdf资源

启动这块的代码为
Uri uri = Uri.parse("file://" + file.getPath());Intent pdfIntent = new Intent(Intent.ACTION_VIEW, uri);pdfIntent.putExtra("isTasking", "false");pdfIntent.putExtra("code", fileName);pdfIntent.putExtra("url", url);pdfIntent.setClass(context, PdfViewerActivity.class);context.startActivity(pdfIntent);有些参数可以不传（这是项目需要）
4.打开txt文件
这个就简单了直接读取txt文件
读取方法
new Thread() {public void run() {File file = new File(SdCardUtil.getSourcePath() + code);if (file.exists()) {try {InputStream in = new FileInputStream(file);String string = getString(in);Message msg = handler.obtainMessage();msg.obj = string;handler.sendMessage(msg);} catch (FileNotFoundException e) {// TODO Auto-generated catch blocke.printStackTrace();}}};}.start();public static String getString(InputStream inputStream) {InputStreamReader inputStreamReader = null;try {inputStreamReader = new InputStreamReader(inputStream, "gbk");} catch (UnsupportedEncodingException e1) {e1.printStackTrace();}BufferedReader reader = new BufferedReader(inputStreamReader);StringBuffer sb = new StringBuffer("");String line;try {while ((line = reader.readLine()) != null) {sb.append(line);sb.append("\n");}} catch (IOException e) {e.printStackTrace();}return sb.toString();}
