How To Validate an EditText to handle numbers only in Android?

Question

How can I validate a text view in android to handle positive integer numbers?

I don't want it to accept any character or signs etc...

Answer 1

Have you taken a look at the EditText's inputType attribute? You can set a whole bunch of different input types that the EditText should limit the user input to.

From the sounds of it, you're probably looking for something like:

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

Answer 2

IMO best way is use inputType in xml

<EditText
    ...
    android:inputType="phone" />

You have to remember that "+" is also part of the phone number.

Answer 3

You can use regular expressions. See: http://developer.android.com/reference/java/util/regex/Pattern.html

Your pattern could look like ^[0-9]{1,10}$ which means that the entered value can only consist of digits (minimum 1, maximum 10)

Answer 4

Use the code in your Edittext XML to restrict any range of values

android:digits="0123456789"

Answer 5

You can use from XML

<EditText
    ...
    android:inputType="phone" />

or programmatically

EditText editText = (EditText) findViewById(R.id.yourId);
editText.setInputType(InputType.TYPE_CLASS_NUMBER);
