Android下利用Apache POI 開啟DOC 文檔

有孩紙在做軟體設計大賽的一題目，需要能查看Doc 和各種office 文檔，搜尋自然便看到了POI，據說POI 文檔寫的不好，不過其他的貌似不是太簡單，就是太複雜。

操作了一下，把檔案開啟了。記錄一下。

1. POI 項目首頁：點擊開啟POI首頁

首頁上很大的幾個單詞： Apache POI - the Java API for Microsoft Documents

2. 下載了最新的 3.9 的 bin 和 src 。

3. 看見首頁裡有 component 一段，看了下，英語也不大好，大意是說什麼不是所有情況下所有的包都需要被匯入，（確實，操作DOC時就匯入了兩個包，產生後的APK竟然達到5.X M）。

Component Map The Apache POI distribution consists of support for many document file formats. This support is provided in several Jar files. Not all of the Jars are needed for every format. The following tables show the relationships between POI components, Maven repository tags, and the project's Jar files. Component Application type Maven artifactId POIFS OLE2 Filesystem poi HPSF OLE2 Property Sets poi HSSF Excel XLS poi HSLF PowerPoint PPT poi-scratchpad HWPF Word DOC poi-scratchpad HDGF Visio VSD poi-scratchpad HPBF Publisher PUB poi-scratchpad HSMF Outlook MSG poi-scratchpad XSSF Excel XLSX poi-ooxml XSLF PowerPoint PPTX poi-ooxml XWPF Word DOCX poi-ooxml OpenXML4J OOXML poi-ooxml-schemas, ooxml-schemas This table maps artifacts into the jar file name. "version-yyyymmdd" is the POI version stamp. For the latest release it is 3.6-20091214. Maven artifactId Prerequisites JAR poi commons-logging, commons-codec, log4j poi-version-yyyymmdd.jar poi-scratchpad poi poi-scratchpad-version-yyyymmdd.jar poi-ooxml poi, poi-ooxml-schemas, dom4j poi-ooxml-version-yyyymmdd.jar poi-ooxml-schemas (*) xmlbeans, stax-api-1.0.1 poi-ooxml-schemas-version-yyyymmdd.jar poi-examples (*) poi, poi-scratchpad, poi-ooxml poi-examples-version-yyyymmdd.jar ooxml-schemas xmlbeans, stax-api-1.0.1 ooxml-schemas-1.1.jar (*) starting with 3.6-beta1-20091124. poi-ooxml requires poi-ooxml-schemas. This is a substantially smaller version of the ooxml-schemas jar (ooxml-schemas-1.1.jar for POI 3.7 or later, ooxml-scheams-1.0.jar for POI 3.5 and 3.6). The larger ooxml-schemas jar is normally only required for development The OOXML jars require a stax implementation. Previously we suggested "geronimo-stax-api_1.0_spec", but now "stax-api-1.0.1" is used for better compatibilty with other Apache projects. Any compliant implementation should work fine though.

也就是說，如果我要操作 DOC 文檔的話 ，只需要引用兩個jar就可以了：poi-scratchpad 和 poi。

4. 配置 。

建立，匯入jar，還有很重要的就是就是在如下配置中勾選這兩個包，否者在編譯時間可能沒問題，運行時卻會提示無法解析 啥的。

5. 貼代碼：

/*      * Fuction:openDocFormPath     * Open a file use file path     * Input: pathname      * Return:A HWPFdocument object     * Author:j.ghang@hotmail.com 2013.05.22      */    private HWPFDocument openDocFromPath(String pathname) {    File docFile = null;    InputStream fileInputS = null;    HWPFDocument doc = null;    docFile= new File(pathname);    try {fileInputS = new FileInputStream(docFile);} catch (FileNotFoundException e) {// TODO 自動產生的 catch 塊e.printStackTrace();}    try {doc = new HWPFDocument(fileInputS);} catch (IOException e) {// TODO 自動產生的 catch 塊e.printStackTrace();}       return doc;    }    

public class Doc3 extends Activity {private TextView doc_text = null;private Button btn_show = null;private String pathname = "/mnt/sdcard/test.doc";private String content = "content";    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_doc3);                 HWPFDocument doc = null;        doc = openDocFromPath(pathname);Range r = doc.getRange();content = r.text();r.delete();doc_text = new TextView(this);btn_show = new Button(this);this.btn_show = (Button)super.findViewById(R.id.btn_show); //this.doc_text = (TextView)super.findViewById(R.id.hello);//this.btn_show.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {// TODO 自動產生的方法存根  doc_text.setText(content);//doc_text.setText("hello hello!!!");  new AlertDialog.Builder(Doc3.this).setTitle("Tips").setMessage(content).show();  }});    }

6. 貼運行。
