I have a preference to get port of a service as shown below 

  <EditTextPreference 
    android:defaultValue="4444" 
    android:key="port" 
    android:title="Port" 
    android:dependency="service_on"  
    android:inputType="number"      
    android:maxLength="4"        
    />

I have restricted it to maxLength 4 but there does not seem to be a minlength or minvalue ??

Basically I want to avoid empty values or lower value ports to avoid conflicts of port already in use/ android allocated ports etc

Any ideas how can I smartly changed the xml only without having to check on callbacks/listeners ?

Thanks,

Ahmed

  • You can't. You will need some (Java) code to parse the text and determine whether or not it's a valid port. – Cat Dec 27 '12 at 17:53
