How do you keep the keyboard open?

[DeepWorksStudios]

Tested On Android 10 API 29 Samsung S9+ Seems like you really need to have the keyboard open and get the picker in focus and than you can type aswell in the case you selected somthing.

Look at the recording

We've moved this issue to the Backlog milestone. This means that it is not going to be worked on for the coming release. We will reassess the backlog following the current release and consider this item at that time. To learn more about our issue management process and to have better expectation regarding different types of issues you can read our Triage Process.

This can also be tested with a device that has a keyboard attached, or in the emulator. Which is perhaps easier to test than trying desperately to keep the on-screen keyboard open.

Any updates ?

Hi, @DeepWorksStudios I had the same problem as you. If you just want to disable the key input of Picker, you can do it by the following method. https://github.com/cat0363/Maui-Workaround8265

It is possible by reimplementing PickerHandler and setting KeyListener=null in CreatePlatformView. However, this is a workaround, not a solution.

[DeepWorksStudios]

@cat0363 thanks for the tipp. I will try that workaround out but its unfortunate that the bug still remains unfixed by the developer team :/

Im also experiencing this issue on android device with physical keyboard. I will look into the workaround. Thanx

I investigated this problem again and found that the behaviour of my real devices is now as expected by default and the problem does not occur, but I found out why because they behave differently. The page pushes up as soon as you open the virtual keyboard, and only in the emulator or with a physical keyboard connected (or possibly a phone with a physical keyboard) can you switch to the picker by pressing the tab key, for example. in the past, the page did not push up, as the above entry confirms.

adding thouse commands to the app.xaml forces the app to act as wanted without pushing up the page (because its not suitable for exsample a chat app) and that way you still can cause the issuee as descirbed in the initial post

 xmlns:android="clr-namespace:Microsoft.Maui.Controls.PlatformConfiguration.AndroidSpecific;assembly=Microsoft.Maui.Controls"
 android:Application.WindowSoftInputModeAdjust="Resize"

i will update the repo accordingly

[DeepWorksStudios]

@jsuarezruiz Could you take care of this problem as soon as you have time? We would all appreciate it very much.

I have provided additional information on this problem in my last post

[DeepWorksStudios]

Any updates?

[DeepWorksStudios]

Unfortunately no one is responding even though I have provided new information on this issue. It's like it doesn't make a difference, I'm really starting to doubt if it's worth it for me to keep reporting this problem as more time is spent on these reports and diagnosing and if it's not fixed in a respectable amount of time, it's not worth my time. Let someone else do it

[DeepWorksStudios]

Does anyone work on this issue?

[DeepWorksStudios]

Its still present with the latest version of dotnet 8 and the lastest version of .net maui 8.0.6

[DeepWorksStudios]

I updated the repo accordingly

If it helps, I managed to workaround with the following code, using a renderer to make sure it applies to all pickers within the app. It basically hides the keyboard on focus.

`#if ANDROID Microsoft.Maui.Handlers.PickerHandler.Mapper.AppendToMapping("PickerKeyboard", (handler, view) => { handler.PlatformView.FocusChange += (s, e) => { if (e.HasFocus) { var imm = (Android.Views.InputMethods.InputMethodManager)handler.PlatformView.Context.GetSystemService(Android.App.Activity.InputMethodService); imm.HideSoftInputFromWindow(handler.PlatformView.WindowToken, 0); } }; });

endif`

        Microsoft.Maui.Handlers.PickerHandler.Mapper.AppendToMapping("PickerKeyboard", (handler, view) =>

            handler.PlatformView.FocusChange += (s, e) =>

            {

                if (e.HasFocus)

                {

                    var imm = (Android.Views.InputMethods.InputMethodManager)handler.PlatformView.Context.GetSystemService(Android.App.Activity.InputMethodService);

                    imm.HideSoftInputFromWindow(handler.PlatformView.WindowToken, 0);

                }

            };

        });

endif`

Sadly that won't solve the issue since if a keyboard is connected or the emulator is used than it does not need the display keyboard shown you can just type and it will modify the picker text unwanted.. I hope they soon solve this issue it's been a time..

Can you verify this issue with the latest version just to make sure

[pauldiston]

This issue seems to be still present in 8.0.14.

This issue seems to be still present in 8.0.14.

I know but no body from the dev team cares 🤷🏻‍♂️

I gave up on Maui and stoped updating my issues let alone reporting new ones

[CleverSoftwarePoland]

Any news on this problem?

[DeepWorksStudios]

i wonder if they worked on this issue or not

[sup3rgalou]

Any update on a potential fix ? We happened to reproduce this two different ways :

• Using an emulator by clicking on the picker with the mouse and typing with the computer keyboard
• Using a real device (galaxy tab s7), by using the S PEN to click on the picker and draw letters
