EditText为空/双

Question

我的APP中有4个编辑文本，包含小时和分钟

  double hour;
                    try {
                        hour= Double.parseDouble(dayhour.getText().toString().replace(',', '.'));
                    } catch (NumberFormatException e) {
                        hour = 0; 
                    }

  double minute;

                    try {
                        minute= Double.parseDouble(dayminute.getText().toString().replace(',', '.'));
                    } catch (NumberFormatException e) {
                        minute= 0; 
                    }
  double hour1;
                    try {
                    hour1= Double.parseDouble(dayhour1.getText().toString().replace(',', '.'));
                    } catch (NumberFormatException e) {
                    hour1= 0; 
                    }

  double minute1;

                    try {
                    minute1= Double.parseDouble(dayminute1.getText().toString().replace(',', '.'));
                    } catch (NumberFormatException e) {
                    minute1= 0; 
                    }

如果未填写编辑文字小时的值，我该怎么做才能获得小时1的值？与分钟编辑文本相同的情况。

Answer 1

如果你做了那个改变怎么办

  try {
                    hour= Double.parseDouble(dayhour.getText().toString().replace(',', '.'));
                } catch (NumberFormatException e) {
                    hour = null; 
                }

然后在执行完所有4个代码块之后进行测试：

if (hour==null) {
dayhour.setText("" + hour1);
}

Answer 2

if(!TextUtils.isEmpty(dayhour.getText().toString()))
{
   hour= Double.parseDouble(dayhour.getText().toString().replace(',', '.'));
}
else
{
   hour= Double.parseDouble(dayhour1.getText().toString().replace(',', '.'));
   // hour = hour1; // if you already have the value of hour1.
}

分钟和秒的相同方式
