Java读取word文件，字体，颜色
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
在Android讀取Word文件時，在網上查看時可以用tm-extractors，但好像沒有提到怎么讀取Word文檔中字體的顏色，字體，上下標等相關的屬性。但由于需要，要把doc文檔中的內容（字體，下劃線，顏色等）讀取應用到android中（不包括圖片和圖表）。
后面采用的是poi三方jar包（原包太大，可以從源代碼里自己抽取有用的一些代碼減少包的大小）。
我的想法是：把doc中的內容解析出來后，加上html對應的標簽，在android中通過Html.fromHtml在TextView中進行顯示，或者通過WebView.loadData進行加載顯示
但測試后，發現如果加載太多內容的話，在Android中效率不行。
?
效果（該圖的效果是在TextView中的效果，在WebView中效果會更好些）：

做法１：（解析為span樣式的，這種做法只能用WebView方式加載，Html.fromHtml無效）
?
Java代碼??
????public?static?String?readDocToSpanByRun(InputStream?inputStream)?{??????????HWPFDocument?hwpfDocument?=?null;??????????if(inputStream?==?null)??????????????throw?new?RuntimeException("inputStream?is?null?...");??????????try{??????????????hwpfDocument?=?new?HWPFDocument(inputStream);??????????}catch(Exception?e)?{??????????????throw?new?RuntimeException("HWPFDocment?Exception",?e);??????????}??????????Range?allRange?=?hwpfDocument.getRange();??????????int?length?=?allRange.numCharacterRuns();??????????StringBuffer?sb?=?new?StringBuffer();??????????CharacterRun?cur;??????????String?text?=?"";??????????for?(int?i?=?0;?i?<?length;?i++)?{??????????????cur?=?allRange.getCharacterRun(i);??????????????sb.append(CharacterRunUtils.toSpanType(cur));??????????????text?=?CharacterRunUtils.getSpicalSysbomByRun(cur.text());??????????????if(cur.getSubSuperScriptIndex()?==?1)??????????????????sb.append("<sup>").append(text).append("</sup>");??????????????else?if(cur.getSubSuperScriptIndex()?==?2)???????????????????sb.append("<sub>").append(text).append("</sub>");??????????????else???????????????????sb.append(text);??????????????sb.append("</span>");??????????}??????????return?sb.toString();??????}???????? ?
做法２：（解析為font樣式的，Html.fromHtml有效，但對應size的設置無效果）
?
Java代碼??
????public?static?String?readDocToHtml(InputStream?inputStream)?{??????????HWPFDocument?hwpfDocument?=?null;??????????if(inputStream?==?null)??????????????throw?new?RuntimeException("inputStream?is?null?...");??????????try{??????????????hwpfDocument?=?new?HWPFDocument(inputStream);??????????}catch(Exception?e)?{??????????????throw?new?RuntimeException("HWPFDocment?Exception",?e);??????????}??????????CharacterRun??cur?=?null;??????????StringBuffer?sb?=?new?StringBuffer();??????????StringBuffer?charStr?=??new?StringBuffer();??????????Range?allRange?=?hwpfDocument.getRange();??????????for(int?i?=?0;?i?<?allRange.numCharacterRuns();?i++)?{??????????????cur?=?allRange.getCharacterRun(i);??????????????sb.append(CharacterRunUtils.fontFaceColorSizeToHtml(cur));??????????????charStr.append(CharacterRunUtils.toSupOrSub(cur,?CharacterRunUtils.getSpicalSysbomByRun(cur.text())));??????????????if(cur.isBold())??{??????????????????charStr.insert(0,?"<b>");??????????????????charStr.insert(charStr.length(),?"</b>");??????????????}??????????????if(cur.getUnderlineCode()?!=?0)?{???????????????????charStr.insert(0,?"<u>");??????????????????charStr.insert(charStr.length(),?"</u>");??????????????}??????????????if(cur.isItalic())?{??????????????????charStr.insert(0,?"<i>");??????????????????charStr.insert(charStr.length(),?"</i>");??????????????}??????????????if(cur.isStrikeThrough())?{??????????????????charStr.insert(0,?"<s>");??????????????????charStr.insert(charStr.length(),?"</s>");??????????????}??????????????sb.append(charStr).append("</font>");??????????????charStr.setLength(0);??????????}??????????hwpfDocument?=?null;??????????return?sb.toString();??????}?? ?
以下是會用到的方法：

用到的顏色的轉換（進行簡單的顏色轉換）
?
Java代碼??
public?class?ColorUtils?{????????public?static?int??red(int?c)?{??????????return?c?&?0XFF;??????}????????????public?static?int?green(int?c)?{??????????return?(c?>>?8)?&?0XFF;??????}????????????public?static?int?blue(int?c)?{??????????return?(c?>>?16)?&?0XFF;??????}????????????public?static?int?rgb(int?c)?{??????????return?(red(c)?<<?16)?|?(green(c)?<<8)?|?blue(c);??????}????????public?static?String?rgbToSix(String?rgb)?{??????????int?length?=?6?-?rgb.length();??????????String?str?=?"";??????????while(length?>?0){??????????????str?+=?"0";??????????????length--;??????????}??????????return?str?+?rgb;??????}????????????public?static?String?getHexColor(int?color)?{??????????color?=?color?==?-1???0?:?color;??????????int?rgb?=?rgb(color);??????????return?"#"?+?rgbToSix(Integer.toHexString(rgb));??????}??}?? ?
