How do I only retrieve numbers in an EditText instead of the whole String?

Question

Double value = Double.valueOf(temp.getText().toString());

Let's say editText temp is 32 Celsius. I only want to get 32 instead of "32 Celsius" so how would I be able to do this? Is this possible?

I'm a newbie with Android Studio.

The simplest way that comes into my mind is

Double value = Double.valueOf(temp.getText().toString().split(" ")[0]);

which splits the string using the space and only takes the first value in the generated array.

This works if the user enters something like "[any_number] [any other string, even more words]".
i.e.: "32 Celsius", "952 years ago", "4 pieces of cake", ...

What if 32 Fahrenheit was an input a user gave. How would I do that then? I always just want the numbers, whatever String they enter afterwards doesn't matter. – Marcella Ruiz Sep 18 '15 at 17:58

I mean I don't always know what exact what word the user is going to enter. Do I have to know the exact word in order for it to be excluded from retrieving the text? – Marcella Ruiz Sep 18 '15 at 18:02
