在 inputType numberDecimal 在的EditText 使用点。作为小数点分隔符。在欧洲它的共同使用逗号，来代替。虽然我的区域设置为德国小数点分隔符仍是'。

The inputType numberDecimal in EditText uses the dot '.' as decimal separator. In Europe it's common to use a comma ',' instead. Even though my locale is set as german the decimal separator is still the '.'

有没有办法让逗号作为小数点分隔符？

Is there a way to get the comma as decimal separator?

推荐答案

一个解决方法（直到谷歌修复这个bug）是使用的EditText 与 Android的：inputType =numberDecimal和机器人：0123456789位数= 。

A workaround (until Google fix this bug) is to use an EditText with android:inputType="numberDecimal" and android:digits="0123456789.,".

然后，TextChangedListener添加到的EditText具有以下afterTextChanged：

Then add a TextChangedListener to the EditText with the following afterTextChanged:

public void afterTextChanged(Editable s) {
    double doubleValue = 0;
    if (s != null) {
        try {
            doubleValue = Double.parseDouble(s.toString().replace(',', '.'));
        } catch (NumberFormatException e) {
            //Error
        }
    }
    //Do something with doubleValue
}
