android - 如何在android editText中显示两位小数？

Question

我将值格式化为两位小数:edAmount.setText(String.format("%.2f", balancePayment));在 Log.d 中显示格式化值:

"Log.d("String format:",String.format("%.2f", balancePayment)); 
D/String format:: 22.00

但是Edit text显示"22.0"是什么原因？

Answer 1

  NumberFormat formatter = NumberFormat.getNumberInstance();
    formatter.setMinimumFractionDigits(2);
    formatter.setMaximumFractionDigits(2);
    String output = formatter.format(balancePayment);
edAmount.setText(output);
