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 =
APP if (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; }
