Android Java读取excel内容代码

好的，以下是Java读取Excel内容的示例代码：

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.ss.usermodel.Sheet;
import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;

public class ReadExcel {
   public static void main(String[] args) throws IOException {
       FileInputStream inputStream = new FileInputStream(new File("sample.xlsx"));

       Workbook workbook = new XSSFWorkbook(inputStream);
       Sheet sheet = workbook.getSheetAt(0);
       // 遍历行
       for (Row row : sheet) {
           // 遍历列
           for (Cell cell : row) {
               // 读取单元格内容并输出
               switch (cell.getCellType()) {
                   case STRING:
                       System.out.print(cell.getStringCellValue() + "\t");
                       break;
                   case NUMERIC:
                       System.out.print(cell.getNumericCellValue() + "\t");
                       break;
                   case BOOLEAN:
                       System.out.print(cell.getBooleanCellValue() + "\t");
                       break;
                   default:
                       System.out.print("\t");
               }
           }
           System.out.println();
       }
       workbook.close();
       inputStream.close();
   }
}

注意，需要导入Apache POI的库来操作Excel文件。
