مع خالص الشكر درس جميل جدا أفضل من دروس موقع اندرويد وxamarin

لدي اضافات:

// I define the button and textview by new local variables as example buttonZZ, textViewZZ -- ahf.ksa@gmail.com
// Note: it's better to not change the object id after make relationship between them to avoid errors

Button buttonZZ = FindViewById<Button>(Resource.Id.buttonX);
TextView textViewZZ = FindViewById<TextView>(Resource.Id.textViewX);

// Execute something during this event handler Click -- ahf.ksa@gmail.com
buttonZZ.Click += delegate
{

textViewZZ.Text = "Ok, u excute something";

};


// Execute something during this event handler Click -- ahf.ksa@gmail.com
textViewZZ.LongClick += delegate
{
buttonZZ.Text = textViewZZ.Text ;

// Or we can use: buttonZZ.Text = FindViewById<TextView>(Resource.Id. textViewZZ).Text;

};
