Show Toast notification if EditText is empty

Question

I have 7 Edit Text fields in my Activity

I have values where text from EditText is writing

For example:

EditText misto = FindViewById<EditText>(Resource.Id.misto) ;
city = misto.Text;

How I can check empty EditText and don't start new activity when user don't fill all fields?

I using Xamarin (c#) for making Android app.

Answer 1

You could use something like:

if(string.IsNullOrEmpty(misto.Text))
{
   // do something
}

to check for empty strings.
