在xamarin中获取从模板到视图模型的单击命令

public class Command : ICommand
{
    private readonly Action _execute;
    private readonly Func<bool> _canExecute;

    public Command(Action execute, Func<bool> canExecute = null)
    {
        _execute = execute;
        _canExecute = canExecute;
    }

    public event EventHandler CanExecuteChanged;

    public bool CanExecute(object parameter)
    {
        return _canExecute?.Invoke() ?? true;
    }

    public void Execute(object parameter)
    {
        _execute?.Invoke();
    }
}

public class MyViewModel
{
    public ICommand MyCommand { get; }

    public MyViewModel()
    {
        MyCommand = new Command(ExecuteMyCommand, CanExecuteMyCommand);
    }

    private void ExecuteMyCommand()
    {
        // 在这里执行单击命令的逻辑
    }

    private bool CanExecuteMyCommand()
    {
        // 在这里判断单击命令是否可执行的条件
        return true;
    }
}

<Button Text="Click Me" Command="{Binding MyCommand}" />
