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 readExcelToAssets(Context context) {
List 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 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：
*
* APP
*
*/
public static List parseDateSource(Context context) {
List 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();
// APP
// 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;
} 完整的FileUtil工具类：
