editview输入数字限制

1、只能输入小数点后两位（0.00）

 //输入框监听
        binding.enterAmount.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {

            }

            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {

            }

            @Override
            public void afterTextChanged(Editable s) {

                if (canDrawMoney >= limitWithDraw) {
                    String temp = s.toString();
                    //返回“.”的位置
                    int posDot = temp.indexOf(".");
                   if (posDot <= 0) {
                      //  return;
                    } else if (temp.length() - posDot - 1 > 2) {
                        s.delete(posDot + 3, posDot + 4);
                    }

                    if (StringUtil.getString2Double(s.toString()) * 100 > canDrawMoney) {
                        binding.withdarwMoney.setTextColor(getResources().getColor(R.color.tip_red));
                        binding.withdarwMoney.setText("金额已超过可提现余额");
                        binding.withdarw.setEnabled(false);
                        binding.withdarw.setBackgroundResource(R.mipmap.ic_bg_bt_gray);

                    } else {
                        binding.withdarwMoney.setTextColor(getResources().getColor(R.color.tip_gray));
                        binding.withdarwMoney.setText("可提现余额 " + CommonUtils.toPrice(canDrawMoney) + "元");
                        binding.withdarw.setEnabled(true);
                        binding.withdarw.setBackgroundResource(R.mipmap.ic_bg_bt_blue);
                    }

                } else {
                    binding.withdarwMoney.setTextColor(getResources().getColor(R.color.tip_gray));
                    binding.withdarwMoney.setText("可提现余额 " + CommonUtils.toPrice(canDrawMoney) + "元");
                    binding.withdarw.setEnabled(false);
                    binding.withdarw.setBackgroundResource(R.mipmap.ic_bg_bt_gray);
                }

            }
        });

二、只能输入正整数并且0开头无法输入数字

String text = s.toString();
                    int len = s.toString().length();
                    if (len > 1 && text.startsWith("0")) {
                        s.replace(1, 2, "");//输入0后无法输入任何数字
//                        s.clear();
                    }





xml文件

                    android:maxLength="10"
                    android:maxLines="1"
