android - 在 jexcelapi 中编码

Question

我使用 jexcelapi for android .

我写字符串“Hello jExcelAPI!”，但是当我读的时候我看到了中文符号。

我该如何解决？

提前致谢。

附言也许有帮助:我不知道需要在 ws.setCharacterSet(cs) 中给出什么；

package ru.elvigl.hello;

import java.io.File;
import java.io.IOException;
import java.util.Locale;

import jxl.Cell;
import jxl.Sheet;
import jxl.Workbook;
import jxl.WorkbookSettings;
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;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.TextView;

public class HellojExcelAPIActivity extends Activity {

    final File file = new File("/sdcard/Folder/File.xls");

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }

    public void btnExport_Click(View v) throws IOException, RowsExceededException, WriteException {
        WorkbookSettings ws = new WorkbookSettings();

        //ws.setCharacterSet(cs);
        ws.setEncoding("Cp1251");
        ws.setExcelDisplayLanguage("RU");
        ws.setExcelRegionalSettings("RU");
        ws.setLocale(new Locale("ru", "RU"));

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

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

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

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

        WorkbookSettings ws = new WorkbookSettings();

        //ws.setCharacterSet(cs);
        ws.setEncoding("Cp1251");
        ws.setExcelDisplayLanguage("RU");
        ws.setExcelRegionalSettings("RU");
        ws.setLocale(new Locale("ru", "RU"));

        Workbook workbook = Workbook.getWorkbook(file, ws); 
        Sheet sheet = workbook.getSheet(0); 
        Cell a1 = sheet.getCell(0,0); 
        String str = a1.getContents();

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

这是“WorkbookSettings”类的文档:http://jexcelapi.sourceforge.net/resources/javadocs/2_6_10/docs/jxl/WorkbookSettings.html似乎方法“setCharacterSet”仅用于读取(导入)电子表格，如果有帮助则不导出。至于中文字符，我认为它们是由于您的语言环境而显示的。我会使用这些常量通过正确的语言和国家/地区构造函数参数正确实例化您的 Locale 对象:http://docs.oracle.com/javase/1.4.2/docs/api/java/util/Locale.html
