I am using this code, user can enter any string. Want to limit the user to atleast numbers only

   <EditTextPreference 
    android:defaultValue="4444" 
    android:key="port" 
    android:title="Port" 
    android:dependency="service_on"        
    />    

Answer 1

EditTextPreference widgets should take the same attributes as a regular EditText, so use:

android:inputType="number"

Or more specifically use:

android:inputType="numberDecimal"
android:digits="0123456789"

since you want to limit the input to a port number only.
