Learn how to build a native Android renderer for your control and export it to make it available to Xamarin.Forms.
- [Instructor] To create my renderer…for this control in Android,…I'm gonna go add a new folder called Controls…to the Android project,…and then I'm gonna add a new class in there,…and we'll call it NumberEntryRenderer,…just to follow convention.…Now, this is gonna derive from the entry renderer.…So that's a class that Xamarin already has for Android.…I do a quick fix,…we can see Xamarin.Forms.Platform.Android,…is where that's defined,…and by going after that base,…it already knows how to generally render the entry…with the right input control.…
I'm also gonna need a Context in here,…so I'll do Quick Fix and use the Android Content,…call that Context,…and then call the base constructor and pass that in.…I only really need to override one particular method,…in this case, it's OnElementChanged,…I'm gonna let the base class do its thing,…and then what I wanna do is just make sure…the control is there,…the base class did do its job properly,…and if it is, I wanna set the Input Type,…so I'll set the Input Type equal…to InputTypes.ClassNumber,…
