在jexcelapi中编码

Question

我使用jexcelapi for android。

我写下了字符串"Hello jExcelAPI!"，但当我阅读时，我看到了中文符号。

我怎么才能修复它？

提前谢谢。

附言:也许它有帮助:我不知道在ws.setCharacterSet(Cs)中需要给出什么；

        String str = a1.getContents();

        TextView tv = (TextView) findViewById(R.id.tvCellValue);
        tv.setText(str);
    }
}

Answer 1

下面是“WorkbookSettings”类的文档：http://jexcelapi.sourceforge.net/resources/javadocs/2_6_10/docs/jxl/WorkbookSettings.html方法"setCharacterSet“似乎只用于读取(导入)电子表格，如果有帮助，不会导出。至于中文字符，我认为是由于您的地区而显示的。我将使用这些常量通过适当的语言和国家/地区构造函数参数正确地实例化您的语言环境对象：http://docs.oracle.com/javase/1.4.2/docs/api/java/util/Locale.html

Answer 2

我不知道该怎么办：

new java.util.Local(Locale.ENGLISH)是不正确的构造函数。

我使用jdk-6u29，现在我使用jdk-7u1。

在Eclipse中，我使用：

• "UTF-8“文本文件编码
• 编译器编译器1.6版

我在安卓和PC上创建了相同的应用程序，其中我使用的是jexcel_android.jar

关于Hello这个词

在PC byte[] b = a1.getString().getBytes("UTF-8");上

• 72、101、108、108、111

在安卓byte[] b = a1.getString().getBytes("UTF-8");上

• -28，-96，-128，-26，-108，-128，-26，-80，-128，-26，-80，-128，-26，-68，-128

如果在十六进制查看器上打开创建的文件

PC代码如下：

package ru.elvigl.jexcelwin;

import java.io.File;
import java.io.IOException;

import jxl.LabelCell;
import jxl.Sheet;
import jxl.Workbook;
import jxl.read.biff.BiffException;
import jxl.write.Label;
import jxl.write.WritableSheet;
import jxl.write.WritableWorkbook;
import jxl.write.WriteException;
import jxl.write.biff.RowsExceededException;

public class MainClass {

    final static File file = new File("D:/File.xls");

    public static void main(String[] args) 
            throws RowsExceededException, WriteException, IOException, BiffException {  

        writeFile();
        readFile();
    }

    private static void writeFile() 
            throws RowsExceededException, WriteException, IOException{

        WritableWorkbook workbook = Workbook.createWorkbook(file); 
        WritableSheet sheet = workbook.createSheet("First Sheet", 0); 

        Label label = new Label(0, 0, "Hello");
        sheet.addCell(label);

        workbook.write();
        workbook.close(); 

        System.out.println("File created");
    }

    private static void readFile() 
            throws BiffException, IOException{

        Workbook workbook = Workbook.getWorkbook(file); 
        Sheet sheet = workbook.getSheet(0); 

        LabelCell a1 = (LabelCell) sheet.getCell(0,0);

        byte[] b = a1.getString().getBytes("UTF-8");

        System.out.println(str);
    }
}

    public void btnImport_Click(View v) throws BiffException, IOException {

        Sheet sheet = workbook.getSheet(0); 

        LabelCell a1 = (LabelCell) sheet.getCell(0,0);

        byte[] b = a1.getString().getBytes("UTF-8");
    }
