Thanks bot Not exactly sure if these issues have the same root cause. I had a look and tried the "InvalidateMeasure" suggested workaround without success.
private void OnTranslateClicked(object? sender, EventArgs e)
{
TranslationLayout.TranslationX = -TranslationLayout.ColumnDefinitions[1].Width.Value;
(TranslationLayout as IView).InvalidateMeasure();
(CounterBtn as IView).InvalidateMeasure();
InvalidateMeasure();
}
Can repro this issue at Android platform on the 17.10 Preview 7(8.0.21&8.0.40).
I experienced this issue too, but seems it was only on Android so it might be unrelated.
From what I could tell in the Android Layout Inspector, it was due to the WrapperView containing the MaterialButton not being translated, and all interactions with the MaterialButton outside the WrapperView would be ignored. I believe this has to do with ViewHandler.HasContainerView
works in conjunction with TranslationX
/TranslationY
.
I solved it for now with this hacky workaround added to the Android start up sequence (before the app UI is built, I put it in my MainApplication constructor):
// The Android MAUI implementation of translation is broken if the platform view has a container view.
// The translation will only ever be set on the platform view, but the container/wrapper will remain untranslated.
// Might _look_ fine, but you cannot interact with the view if its translated to outside the container.
var applyTranslation = (IViewHandler handler, IView view) =>
{
if (handler.PlatformView is Android.Views.View platformView)
{
if (handler.HasContainer && handler.ContainerView is Android.Views.View containerView)
{
// Only translate the container view.
platformView.TranslationX = 0;
platformView.TranslationY = 0;
containerView.UpdateTranslationX(view);
containerView.UpdateTranslationY(view);
}
else
{
platformView.UpdateTranslationX(view);
platformView.UpdateTranslationY(view);
}
}
};
ViewHandler.ViewMapper.ReplaceMapping(nameof(IView.TranslationY), applyTranslation);
ViewHandler.ViewMapper.ReplaceMapping(nameof(IView.TranslationX), applyTranslation);
ViewHandler.ViewMapper.AppendToMapping(nameof(IViewHandler.ContainerView), applyTranslation);
Description
I am Porting a Xamarin Forms application to .Net Maui. There is a layout used which is not completely visible to the user unless the user presses a button, similar to the Flyout. When the layout get translated into sight the buttons are not clickable on Android and iOS, works completely fine on Windows.
It is easy reproduceable with a few lines of code, see the linked sample
