Android 读取excel（支持 xls）和 xml-Toy模板网

这篇具有很好参考价值的文章主要介绍了Android 读取excel（支持 xls）和 xml。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

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

android 读取excel,android,excel,xml

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;
    }
