Answer 1

试试这个简单的Excel：https://github.com/centic9/poi-on-android

或者android5xlsx： https://github.com/andruhon/android5xlsx

他们的试验来包装和Android上的重新包装Apache的POI。如果您已经熟悉Apache-POI，这将是一个很好的开始。

我希望这可以帮助，'。

1. 的gradle添加进口

编译组： 'net.sourceforge.jexcelapi'，名称： 'JXL'，版本： '2.6'

在AndroidManifest.xml文件中添加权限

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> 
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> 

创建新类ExcelExporter：

import android.os.Environment; 

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

import jxl.Workbook; 
import jxl.WorkbookSettings; 
import jxl.write.Label; 
import jxl.write.WritableSheet; 
import jxl.write.WritableWorkbook; 

public class ExcelExporter { 

    public static void export() { 
     File sd = Environment.getExternalStorageDirectory(); 
     String csvFile = "yourFile.xls"; 

     File directory = new File(sd.getAbsolutePath()); 

     //create directory if not exist 
     if (!directory.isDirectory()) { 
      directory.mkdirs(); 
     } 
     try { 

      //file path 
      File file = new File(directory, csvFile); 
      WorkbookSettings wbSettings = new WorkbookSettings(); 
      wbSettings.setLocale(new Locale(Locale.GERMAN.getLanguage(), Locale.GERMAN.getCountry())); 
      WritableWorkbook workbook; 
      workbook = Workbook.createWorkbook(file, wbSettings); 

      //Excel sheetA first sheetA 
      WritableSheet sheetA = workbook.createSheet("sheet A", 0); 

      // column and row titles 
      sheetA.addCell(new Label(0, 0, "sheet A 1")); 
      sheetA.addCell(new Label(1, 0, "sheet A 2")); 
      sheetA.addCell(new Label(0, 1, "sheet A 3")); 
      sheetA.addCell(new Label(1, 1, "sheet A 4")); 

      //Excel sheetB represents second sheet 
      WritableSheet sheetB = workbook.createSheet("sheet B", 1); 

      // column and row titles 
      sheetB.addCell(new Label(0, 0, "sheet B 1")); 
      sheetB.addCell(new Label(1, 0, "sheet B 2")); 
      sheetB.addCell(new Label(0, 1, "sheet B 3")); 
      sheetB.addCell(new Label(1, 1, "sheet B 4")); 

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

     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
    } 
} 

在你MainActivity添加下面的方法：

private void askForPermission(String permission, Integer requestCode) { 
    if (ContextCompat.checkSelfPermission(StartMenu.this, permission) 
      != PackageManager.PERMISSION_GRANTED) { 

     // Should we show an explanation? 
     if (ActivityCompat.shouldShowRequestPermissionRationale(
       StartMenu.this, permission)) { 

      //This is called if user has denied the permission before 
      //In this case I am just asking the permission again 
      ActivityCompat.requestPermissions(StartMenu.this, 
        new String[]{permission}, requestCode); 

     } else { 
      ActivityCompat.requestPermissions(StartMenu.this, 
        new String[]{permission}, requestCode); 
     } 
    } else { 
     Toast.makeText(this, permission + " is already granted.", 
       Toast.LENGTH_SHORT).show(); 
    } 
} 

1. 查找执行出口的地方，例如：

@Override 
protected void onResume() { 
    super.onResume(); 
    askForPermission(Manifest.permission.READ_EXTERNAL_STORAGE, READ_EXST); 
    askForPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE, WRITE_EXST); 
    ExcelExporter.export(); 
}
