Question

I’m developing Android application, and I need to disable letters for user’s keyboard in order to allow user to input only digits in EditText. Please, tell me, is it possible?

Answer 1

add android:inputType="number" to the EditText in the layout xml.

More information on inputType’s can be found at http://developer.android.com/reference/android/widget/TextView.html#attr_android:inputType

You can also go further and do something like:

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