Xamarin在活动之间传递数据

Question

I can not share data between 2 activity:

Activity1

homeButton.Click += delegate {
    var second = new Intent(this, typeof(SecondPage));
    second.PutExtra("reg", "qwe");
    StartActivity (typeof(SecondPage));
    }

Acitvity2(SecondPage)

string txt = Intent.GetStringExtra ("reg") ?? "null";

Console.WriteLine (txt);

Still get null, any suggestions?

Answer 1

For a start, you should pass the intent you created:

homeButton.Click += delegate {
    var second = new Intent(this, typeof(SecondPage));
    second.PutExtra("reg", "qwe");
    StartActivity (second);
    }
