Apache Poi Android
我Apache Poi在Android应用程序中使用，但是出现了问题HSSFWorkbook。
我只想读取在Android平板电脑的内存中找到的Excel文件。（要在Android应用程序中显示数据）
我的代码：
@Overrideprotected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
try {
AssetManager assetManager = this.getAssets();
InputStream input = assetManager.open("test42.XLS");
HSSFWorkbook classeur = new HSSFWorkbook(input);
//HSSFSheet feuille = classeur.getSheetAt(0);
//Cell cell = feuille.getRow(1).getCell(1);
//String value = cell.getStringCellValue();
TextView tv = new TextView(this);
tv.setText("Test");
setContentView(tv);
} catch (IOException e) {
e.printStackTrace();
System.out.println("prob");
}
}

回答：
尝试对xls文件执行以下操作：
try { InputStream caInput = new BufferedInputStream(getAssets().open(
"ie_data.xls"));
HSSFWorkbook workbook = new HSSFWorkbook(caInput);
HSSFSheet feuille = workbook.getSheetAt(0);
Cell cell = feuille.getRow(1).getCell(1);
String value = cell.getNumericCellValue()+"";
Toast.makeText(getApplicationContext(), value, Toast.LENGTH_LONG)
.show();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
对于xlsx：
1-导入以下jar文件：
（dom4j-1.6.1.jar，poi-ooxml-3.5-FINAL.jar，poi-ooxml-
schemas-3.8-beta4.jar，poi-3.9-20121203.jar，xmlbeans-2.3.0.jar）。
第二-在try catch块内进行以下操作：
如果您使用的是File对象，请执行以下操作：
File file = new File("path"); InputStream caInput = new FileInputStream(file);
如果您正在使用inputStram读取文件，请执行以下操作：
InputStream caInput = new BufferedInputStream(getAssets().open( "ie_data.xlsx"));
XSSFWorkbook workbook = new XSSFWorkbook(caInput);
XSSFSheet feuille = workbook.getSheetAt(0);
Cell cell = feuille.getRow(0).getCell(0);
String value = cell.getStringCellValue() + "";
System.out.print("hello = " + value);
但请注意，根据我的xslx文件，我正在获取StringCellValue，应检查xlsx文件，并查看其是否为字符串，并使用getStringCellValue（）或Numeric并使用getNumericCellValue（）。
请给我一些反馈
希望能有所帮助。
