以编程方式将一列中的值从android总结为excel

Question

当我尝试总结一个这样的列中的值时，它给出了0而不是总结它。

然后我在电话中打开sum的值显示为0。

如果我在PC中打开它，它将显示Microsoft Excel自己完成的原始总和值。然后在Mobile中，总和将显示为0，在PC中，总和将显示为280（这是必需的!!）。所以当我在手机中打开excel表时需要解决方案它应该是完美的。

这是代码，

}

private String getColumnName(int columnNumber) {

    String columnName = "";
    int dividend = columnNumber + 1;
    int modulus;

    while (dividend > 0) {
        modulus = (dividend - 1) % 26;
        columnName = (char) (65 + modulus) + columnName;
        dividend = (int) ((dividend - modulus) / 26);
    }

    return columnName;
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();
    if (id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}
}

现在我的问题是，我需要做出哪些改变？

我哪里出错？

请告诉我..

谢谢..

Answer 1

可以确认您的代码创建了一个带有总和公式的Excel工作表，该公式在PC或Windows Phone上汇总确定（总计：280），但在使用Polaris查看器的Android设备上没有。

使用Planmaker应用在不同的Android设备上尝试使用它。它显示确定。此外，Sheet To Go from Documents To Go应用程序将显示280.

那么我们会责怪Polaris观众吗？ -
