.Net MAUI 安卓使用DateTimePicker

效果视频:

教程:

1.DotNet MAUI项目Android端安装安卓nuget包；.

NuGet\Install-Package XamarinLibrary.Net.Android.Loper7.DateTimePicker -Version 0.6.3.2

2.参考原作者Android原生源码用法，创建layout.xml用于显示原生的DateTimePicker；

参考示例源码

Platforms/Android/Resources/layout/DateTimePickerLayout.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout        ......><com.loper7.date_time_picker.DateTimePicker                ...... /></LinearLayout>

3.在DotNet MAUI方面将DateTimePicker相关控件使用ViewHandler方案在Dot Net MAUI上显示，涉及Android的Inflate函数相关知识。

3.1参考示例源码Handlers/TimePickerViewHandler.Android.cs

  public partial class TimePickerViewHandler:ViewHandler<TimePickerView, LinearLayout>  {        ......
        protected override LinearLayout CreatePlatformView()        {            var inflater = LayoutInflater.From(Context);            var result = inflater.Inflate(Resource.Layout.DateTimePickerLayout, null) as LinearLayout;            var picker = result.FindViewById<DateTimePicker>(Resource.Id.picker);            ......            ......            return result;        }    }

3.2初始化配置Handler

参考示例源码MauiProgram.cs

    var builder = MauiApp.CreateBuilder();    builder      ......            .ConfigureMauiHandlers(handlers =>            {#if ANDROID                handlers.AddHandler(typeof(TimePickerView), typeof(TimePickerViewHandler));#endif            });
