java – 如何在十进制后只显示两个数字

[weixin_38080567]

我想在十进制后只显示两位数,我已经尝试但仍然在十进制后得到多位数： itemamount = Double.parseDouble(text_cost_code.getText().toString()); txt_total.setText(new DecimalFormat("##.##").format(itemamount)); edit_qty_code.addTextChangedListener(new TextWatcher() { public void onTextChanged(CharSequence s, int start, int before, int count) { // TODO Auto-generated method stub if (!edit_qty_code.getText().toString().equals("") || !edit_qty_code.getText().toString().equals("")) { itemquantity = Double.parseDouble(edit_qty_code.getText().toString()); itemamount = Double.parseDouble(text_cost_code.getText().toString()); txt_total.setText(new DecimalFormat("##.##").format (itemquantity * itemamount)); } else { txt_total.setText("0.00");}}

Rakesh使用此链接： Show only two digit after decimal i=348842. double i2=i/60000; DecimalFormat dtime = new DecimalFormat("#.##"); i2= Double.valueOf(dtime.format(time)); v.setText(String.valueOf(i2));
