Add a listener on Edit Text android? C#

I'm currently developing for Android using C# and Xamarin.

I have an EditText box within my app where the user can input information. How can I add a listener that will see if the user is actually typing in it? The reason I need this is to link it to analytics, so I can see how many users actually type information.

Thanks!

Implement the ITextWatcher on your Activity, Fragment subclass or create a new Java.Lang.Object class:

public class TextWatcher : Java.Lang.Object, ITextWatcher
{
    public void AfterTextChanged(IEditable s)
    {
        //
    }

    public void BeforeTextChanged(ICharSequence s, int start, int count, int after)
    {
        //
    }

    public void OnTextChanged(ICharSequence s, int start, int before, int count)
    {
        //
    }
}

Add the listener to your EditText instance:

editText.AddTextChangedListener(new TextWatcher());

editText.TextChanged += (object sender, Android.Text.TextChangedEventArgs e) => {

   textView.Text = e.Text.ToString ();

};

Is what I believe you are looking for, more information here

add text change listener and in afterTextChanged Method, save the device's mac address to the server . Because MAC address is always unique 

 Field1.addTextChangedListener(new TextWatcher() {

       @Override
       public void afterTextChanged(Editable s) {}

       @Override    
       public void beforeTextChanged(CharSequence s, int start,
         int count, int after) {
       }

       @Override    
       public void onTextChanged(CharSequence s, int start,
         int before, int count) {

      });

you can count number of users with the help of number of mac addresses
