Same as title.
How to programmatically click the picker button

I want to create a button and when the button is clicked, it will pop up as if the picker was clicked.

I tried using focus() but it doesn't work.

    Hello,

    Which platform is not working when running code?
    Could you minimize the code to just what is needed to reproduce the problem?
    I use the following code to make a test on the Android platform. If I click the button, the picker will be invoked and pop up.
    My Xamarin.Forms version is 5.0.0.2196

       <Picker x:Name="picker"  
              >  
                   <Picker.ItemsSource>  
                       <x:Array Type="{x:Type x:String}">  
                           <x:String>Baboon</x:String>  
                           <x:String>Capuchin Monkey</x:String>  
                             
                       </x:Array>  
                   </Picker.ItemsSource>  
               </Picker>  
         
              <Button Text="click" Clicked="Button_Clicked"></Button>  
         
       private void Button_Clicked(object sender, EventArgs e)  
               {  
                   picker. Focus();  
               }  
    

    Best Regards,
