Resizing the screen when an Entry gets focused in .NET MAUI

When an entry field gets focused, the software keyboard appears, potentially covering the entry field. To provide a better user experience, you need to adjust the screen layout so that the entry field remains visible. First, create a parent class for your views, deriving from ContentPage, and add a HaveKeyboardOffsetProperty. iOS Solution: Next, create the PageElementMapper class to handle the keyboard appearance and adjust the screen layout. Finally, register the mapper in the MauiProgram.cs file. Android solution: On Android, you can use a PropertyChanged method of the HasKeyboardOffset: Remarks The provided solution offers a way to manage this in .NET MAUI on iOS. However, always be open to improvements and share your solutions with the community for better practices. This might not be the best solution to do it.

.NET MAUI Hide software keyboard when tapping out of an Entry on iOS

To hide the software keyboard when the user taps outside the entry field, set the HideSoftInputOnTapped property to True in your ContentPage definition. Please note that the HideSoftInputOnTapped property might not work as expected when tapping on certain controls like ScrollView. In such cases, you might need to implement a custom behavior to handle keyboard dismissal.

Resolving SQLite issues for .NET MAUI

Recently, while working on ExampleApp, we faced two significant errors and found effective solutions for both. Here’s a detailed account of the problems and their resolutions. System.TypeInitializationException To resolve this error, we needed to install the latest NuGet package for SQLitePCLRaw.bundle_green. This package ensures that the necessary SQLite libraries are included in the project. Add the following package reference with the latest version to your project: In the AppDelegate.cs file, add the following line to the CreateMauiApp method: System.ExecutionEngineException in iOS Release Mode This error occurs due to the JIT compilation attempt in AOT-only mode on iOS. The solution is to install this specific version of the sqlite-net-pcl.It will ONLY work with 1.7.355 or below.  This solution is also applicable to Xamarin projects.

Customizing .NET MAUI Map’s pin Z-Order, Rotation, and Anchor point – Android

This post will build upon the excellent tutorial on customizing map pins in .NET MAUI by Vladislav Antonyuk, and focus on adding these specific adjustments for Android. Define the Anchor Points enum, get a method to return anchor floats We start by defining an enum to represent the different anchor points. A helper method, GetAnchorPoint, will return the appropriate anchor coordinates based on the chosen enum value. This method returns the normalized coordinates for each anchor point, which can then be applied to the pin’s icon. Modifications to the Custom Map Handler Now, let’s focus on the custom map handler, where you’ll need to modify how each pin is added to the map. Following the setup from Vladislav’s tutorial, you only need to adjust the following parts in the OnMapReady method for Android:

Disabling Map Zoom Controls and Other Buttons in .NET MAUI Android

In this post, we’ll guide you through the process of disabling these UI elements (zoom controls, compass, and location buttons) in your Android map implementation using a custom map handler. This approach gives you more control over the user experience and map functionality in your mobile app. Creating a Custom Map Handler To disable these controls, we need to customize how the map is rendered on Android. This involves creating a custom map handler that intercepts the way the map is displayed and adjusts its settings. A detailed tutorial for creating custom map handlers can be found in this great guide by Vladislav Antonyuk. We will extend that concept here. First, we need to implement a MapCallbackHandler that disables specific controls when the map is ready. This is done in the OnMapReady method, which is triggered when the map is fully loaded and ready for interaction. In the OnMapReady method, we access the googleMap.UiSettings property, which contains several settings that control the map’s UI. In our example, we set the following to false: You can also adjust other settings here, such as disabling tilt gestures or zoom gestures if needed.
