Android 读取excel（支持 xls）和 xml

一、使用jxl 读取excel文件

1.build.gradle的dependencies中加入

implementation 'net.sourceforge.jexcelapi:jxl:2.6.12'

2.将xls文件复制到assets文件夹

3.读取文件内容：

public static List<ContentBean> readExcelToAssets(Context context) {List<ContentBean> contentBeans = new ArrayList<>();try {InputStream is = context.getAssets().open("App.xls");Workbook book = Workbook.getWorkbook(is);book.getNumberOfSheets();Sheet sheet = book.getSheet(0);int Rows = sheet.getRows();for (int i = 1; i < Rows; ++i) {String key = (sheet.getCell(0, i)).getContents();List<String> values = new ArrayList<>();String value1 = (sheet.getCell(1, i)).getContents();values.add(value1);String value2 = (sheet.getCell(2, i)).getContents();values.add(value2);String value3 = (sheet.getCell(3, i)).getContents();values.add(value3);String value4 = (sheet.getCell(4, i)).getContents();values.add(value4);String value5 = (sheet.getCell(5, i)).getContents();values.add(value5);contentBeans.add(new ContentBean(key, values));Log.e("FileUtil", "第" + i + "行数据=\n" + key + "," + value1 + "," + value2 + "," + value3 + "," + value4 + "," + value5);}book.close();} catch (Exception e) {Log.e("FileUtil", "e" + e);}return contentBeans;}

二、使用XmlPullParser读取xml文件

1.将xml文件复制到assets文件夹

2.读取文件内容：

/*** 获取XML中所有的指令信息* xml文件内容：* <resources>*     <string name="app_name">APP</string>* </resources>*/public static List<LanguageBean> parseDateSource(Context context) {List<LanguageBean> languageBeans = new ArrayList<>();try {InputStream inputStream = context.getAssets().open("strings.xml");XmlPullParser parse = Xml.newPullParser();parse.setInput(inputStream, "utf-8");int event = parse.getEventType();while (event != XmlPullParser.END_DOCUMENT) {switch (event) {case XmlPullParser.START_DOCUMENT:Log.e("FileUtil", "parseDateSource 初始化指令集合");break;case XmlPullParser.START_TAG:String keys = parse.getName();// <string name="app_name">APP</string>// 读取string标签下的值，key = app_name,value = APPif (keys.equals("string")) {String key = parse.getAttributeValue(null, "name");String value = parse.nextText();Log.e("FileUtil", "START_TAG " + key + "," + value);languageBeans.add(new LanguageBean(key, value));} else {Log.e("FileUtil", "START_TAG keys " + keys);}break;case XmlPullParser.END_TAG:Log.e("FileUtil", "END_TAG");break;default:break;}event = parse.next();// 进入到下一个元素并触发相应事件}} catch (IOException e) {e.printStackTrace();} catch (XmlPullParserException e) {e.printStackTrace();}return languageBeans;}
