我在我的資產文件夾中有一個xls文件,我想使用jexcelapi庫打開它。我已經將文件路徑設置爲(「file:///android_asset/jxlrwtest.xls」),甚至嘗試使用New-> File在根文件夾中創建具有不同名稱的xls文件並直接訪問它,但仍然是我每次運行模擬器時都會得到錯誤java.io.FileNotFoundException「(沒有這樣的文件或目錄)」。我也確保每次嘗試移動文件時都會刷新路徑。我的閱讀Excel文件整個類是資產文件目錄給出java.io.FileNotFoundException eclipse
package com.example.kirikedictionary;
import java.io.File;
import java.io.IOException;
import android.app.Activity;
import android.content.Context;
import jxl.Cell;
import jxl.CellType;
import jxl.Sheet;
import jxl.Workbook;
import jxl.read.biff.BiffException;
public class ReadExcel {
private String inputFile;
protected Context context;
public ReadExcel(Context context){
this.context = context.getApplicationContext();
}
public void setInputFile(String inputFile) {
this.inputFile = inputFile;
}
public void read() throws IOException {
File inputWorkbook = new File(inputFile);
Workbook w;
try {
w = Workbook.getWorkbook(inputWorkbook);
// Get the first sheet
Sheet sheet = w.getSheet(0);
// Loop over first 10 column and lines
for (int j = 0; j < sheet.getColumns(); j++) {
for (int i = 0; i < sheet.getRows(); i++) {
Cell cell = sheet.getCell(j, i);
CellType type = cell.getType();
if (type == CellType.LABEL) {
System.out.println("I got a label "
+ cell.getContents());
}
if (type == CellType.NUMBER) {
System.out.println("I got a number "
+ cell.getContents());
}
}
}
} catch (BiffException e) {
e.printStackTrace();
}
}
public void main(String[] args) throws IOException {
ReadExcel test = new ReadExcel(context);
test.setInputFile("file:///android_asset/jxlrwtest.xls");
test.read();
}
}

請幫助,因爲我不希望有使用外部SD卡文件,我在這裏呆了一段時間。
請將您的項目導入到Android Studio。 Eclipse已被棄用,它會產生更多像這樣的問題 – piotrek1543
