使用 Apache POI 打开 .xlsx 文件时发生异常

Question

我一直在开发一个 android 应用程序，我必须在其中打开 .xls 和 .xlsx 文件以进一步实施。在 .xls 的情况下，一切正常，但是当我尝试打开 .xls x 文件时，它给了我异常。下面是我的代码 请帮我解决这些异常

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == RESULT_code  && resultCode == RESULT_OK && null != data) {
            String FileName = data.getData().getLastPathSegment();

            String FilePath = data.getData().getPath();
            if(FilePath.endsWith(".xlsx")){
try{
                    FileInputStream file = new FileInputStream(new File(FilePath));
                    XSSFWorkbook myWorkBook2 = new XSSFWorkbook(file);
                    XSSFSheet mySheet2 = myWorkBook2.getSheetAt(0);}
                catch (FileNotFoundException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } 


                }

我正在使用的罐子：

• dom4j-1.6.1.jar
• log4j-1.2.13.jar
• poi-3.9-20121203.jar
• poi-ooxml-3.9-20121203.jar
• xmlbeans-2.3.0.jar

Logcat 错误

Answer 1

请参阅 Apache POI Components and Dependencies page - 您缺少 poi-ooxml-schemas 文件，这就是为什么您会收到架构类的类未找到异常

Answer 2

JSpreadsheet 是另一个用于 Java 和 Android 的 API。它读取并创建 .xlsx 文件。没有依赖关系，只有一个 jar 文件。
