Why can't I use XML to display text?

[Vito258]

The content of the XML file is as follows.

<TextView
    android:id="@+id/textView1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:text="Hello,World"
    android:textSize="50sp"
    android:textColor="@android:color/holo_red_light"
    android:cursorVisible="true"/>

Text can be displayed on the designer, but not on the emulator.

public class MainActivity : MauiAppCompatActivity
{
public static MainActivity Instance;
}
public class NoticeContentCardViewRenderer : ViewRenderer
{
protected override void OnElementChanged(ElementChangedEventArgs e)
{
var activity = (Activity)MainActivity.Instance;
View = activity.LayoutInflater.Inflate(Resource.Layout.TestLayout, this, false);
SetNativeControl(View);
}
}

Did you register the renderer in your MauiProgram file? Also, you should consider using a handler if this is a new control, renderers are considered legacy.

Thank you! I tried using handler and the text was displayed

Hi @Vito258 I'm trying to do the same thing that you did. Could you please share the code that worked for you? I know I need to implement my own handler, but I'm still confused what it should look like. It would be greatly appreciated.
