我试图从数据库中返回数据并将其保存在 SD 卡中的 CSV 文件中,并附加文件并通过电子邮件发送,这一切都很完美,数据在 Excel 上应该是这样的。
例子
A栏............ B栏
123123232.......约翰
964803400........史密斯
657484738........迈克
我的问题是当我打开 Excel 时,数据显示如下
A栏............ B栏
123123232.......
964803400.......
657484738.......

这是代码Names.Java
dbUser.open();
File root=null;
try {
// check for SDcard
root = Environment.getExternalStorageDirectory();
Log.i(TAG,"path.." +root.getAbsolutePath());
//check sdcard permission
if (root.canWrite()){
File fileDir = new File(root.getAbsolutePath()+"/fun/");
fileDir.mkdirs();
Log.d("PATH",fileDir.toString());
File file= new File(fileDir, "itisfun.csv");
FileWriter filewriter = new FileWriter(file);
BufferedWriter out = new BufferedWriter(filewriter);
String[] div = dbUser.getVname_Mnumber(sharedUsername1,product).toString().split(",");
Log.d(sharedUsername1, product);
Log.d("VVVVVVVVVV", dbUser.getVname_Mnumber(sharedUsername1,product).toString());
for (int i =0; i<div.length;i++)
out.write( div[i] +"\n" );
out.close();
}
} catch (IOException e) {
Log.e("ERROR:---", "Could not write file to SDCard" + e.getMessage());
}
这是我的数据库适配器
public String getVname_Mnumber(String date , String Vname) throws SQLException {
String[] whereArgs = new String[]{date,Vname};
Cursor mcursor = db.rawQuery("SELECT MeterNumber,VendorName FROM " + SCAN_TABLE + " WHERE Date = ? AND VendorName = ? ",whereArgs);
ArrayList<String> results = new ArrayList<String>();
ArrayList<String> results1 = new ArrayList<String>();
while (mcursor.moveToNext()) {
results.add(mcursor.getString(0));
results1.add(mcursor.getString(1));
}
return results + ","+ results1;
}
将感谢您的帮助
