以编程方式更改android:digits

问题描述:

我在布局xml中有这个

I have this in the layout xml

android:digits="0123456789."
android:inputType="phone" />

我想要的是能够以编程方式更改它,并能够来回更改它. inputType部分可以配合使用

What I want is to be able to change it programatically and be able to change it back and forth. The inputType part is fine with

manual_ip.setInputType(InputType.TYPE_CLASS_TEXT);

manual_ip.setInputType(InputType.TYPE_CLASS_PHONE);

但是我对数字部分一无所知. 我需要将字符数限制为"0123456789".或根据复选框状态允许所有操作.

But I'm clueless with digits parts.. I need to limit the chars to "0123456789." or allow everything depending on a checkbox state.

添加

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

之后

manual_ip.setInputType(InputType.TYPE_CLASS_PHONE);

之后没有任何内容

manual_ip.setInputType(InputType.TYPE_CLASS_TEXT);

解决了我的问题!
