Xamarin Android 页面间传值方法:

Xamarin Android 页面间传值方法:

父页面:

Intent intent = new Intent(this, typeof(ChildPage));

 intent.PutExtra("STID", 3);

StartActivityForResult(intent, 1);

子页面接收传值:

var tid = Intent.GetStringExtra("STID");

if (string.IsNullOrEmpty(tid))

    //...

子页面发送返回值:

Intent intent = new Intent();

intent.PutExtra("userPhoneNumber", userPhonNumber);

SetResult(Result.Ok, intent);

Finish();

父页面在OnActivityResult重写方法中接收返回值:

protected override void OnActivityResult(int requestCode, [GeneratedEnum] Result resultCode, Intent data)

{

        if ((requestCode == 1&& resultCode == Result.Ok)

        {

                if (data == null) return;

                var userPhoneNumber = data.GetStringExtra("userPhoneNumber");

                if (string.IsNullOrEmpty(userPhoneNumber))

                        //...

        }

}
