Click event fires when scrolling on EditText to see all its content(Xamarin.Android) - xamarin.android

Question

When I scroll in an EditText to see its content when it's too long, its click event fires. How can I prevent that? The EditText is not editable.
Here is my activity:
public class MainActivity : AppCompatActivity, View.IOnTouchListener
{
EditText et;
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
SetContentView(Resource.Layout.activity_main);
et = FindViewById<EditText>(Resource.Id.editText1);
et.SetOnTouchListener(this);
et.Click += delegate { this.OnClicking(); };
}
private void OnClicking()
{
//Show alert dialog
}
public bool OnTouch(View v, MotionEvent e)
{
v.OnTouchEvent(e);
var imm = (Android.Views.InputMethods.InputMethodManager)v.Context.GetSystemService("input_method");
imm?.HideSoftInputFromWindow(v.WindowToken, Android.Views.InputMethods.HideSoftInputFlags.None);
return true;
}
}
Here is my axml file:
