以编程方式设置 EditText 数字

问题描述

我实际上是在尝试以编程方式设置 EditText 的数字值.到目前为止，我有:

I am essentially trying to set the digits value of an EditText programmatically. So far I have:

weightInput.setInputType(InputType.TYPE_CLASS_PHONE);
weightInput.setKeyListener(DigitsKeyListener.getInstance());

这很好，但我也希望能够包含小数位 (.).有什么想法吗?

Which is fine, but I also want to be able to include a decimal place (.). Any ideas?

推荐答案

试试这个:

<EditText
    android:inputType="number"
    android:digits="0123456789."
/>

来自代码:

weightInput.setKeyListener(DigitsKeyListener.getInstance("0123456789."));
