What android:inputType should I use for entering an IP Address and hostname?

Question

I am building a small Android app where the user will enter an IP address or a hostname into an EditText widget. 90% of the time they will be entering an IP address, the rest of the time - a hostname.

So naturally, I want to make it easy for them to enter an IP address, but the ability to switch to alpha numerics for hostname entry is important.

I can't seem to find a good inputType. The numberDecimal initially seemed like a good shot, but it only allows one dot.

Ideally, I'd like to start with a standard keyboard that had the ?123 button pressed.

How do I get there?

Answer 1

Try using android:inputType="number", but also set android:digits="0123456789.". Works for me.

Answer 2

If you use inputType="phone" you gain access to a cut down keyboard containing Numbers and a Period character - this doesn't restrict the input with regards to the amount of Periods you can enter.

Please see this answer for validation while being entered.

Answer 3

This works perfectly keyboard with numbers and decimal by adding android:inputType="number|numberDecimal" and android:digits="0123456789."

Example

 <EditText
    android:id="@+id/ip_address"
    android:inputType="number|numberDecimal"
    android:digits="0123456789."
    android:layout_width="match_parent"
    android:layout_height="wrap_content"/>
