Is there any way to set an EditText in my XML preference screen to only accept number input?

EditText in Android UI or applications is an input field, that is used to give input text to the application. This input text can be of multiple types like text (Characters), number (Integers), etc.
The android:inputType attribute allows you to specify various behaviors for the input method. Most importantly, if your text field is intended for basic text input (such as for a text message), you should enable auto spelling correction with the "textAutoCorrect" value.
Every text field expects a certain type of text input, such as an email address, phone number, or just plain text. So it's important that you specify the input type for each text field in your app so the system displays the appropriate soft input method (such as an on-screen keyboard).
In the xml file:
android:inputType="number" or during runtime:
editText.setRawInputType(TYPE_CLASS_NUMBER | TYPE_NUMBER_VARIATION_NORMAL); http://developer.android.com/reference/android/widget/TextView.html#attr_android:inputType

EditTextPreference supports all the same XML attributes as does an EditText. So, use android:inputType="number"
