在EditText上滚动以查看其所有内容时，将触发Click事件（Xamarin.Android）

Question

当我滚动EditText以查看其内容时，如果它太长，则会触发其click事件。我该如何预防？ EditText是不可编辑的。

这是我的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;
    }

}

这是我的axml文件：
