How to prevent Entry Return to move to next control?

Question

I am using Microsoft.Maui.Controls.Entry object.
I am setting the ReturnType to Send

Entry entry = new() { ReturnType = ReturnType.Send };

So when completing the keyboard entry and using the Return button, i find the focus is sent to the next input control. As if the ReturnType was set to Next rather than Send

The next input control is a Picker object, and forcing the advancement opens the Picker. This is not desired. How can i prevent that behavior?

Hello,

The ReturnType property only provides a difference in button styles and does not affect program behavior.

Enumerates return button styles. Typically the operating system on-screen keyboard will visually style the return key based on this value.

After testing, this issue only appears on the Android platform.

You could refer to the following code to turn off picker's autofocus function.

<Entry x:Name="myentry"  ReturnType="Send"/>
<Picker x:Name="testPicker"></Picker>


protected override void OnHandlerChanged()
{
    base.OnHandlerChanged();
#if ANDROID
    var edit = testPicker.Handler.PlatformView as EditText;
    if (edit != null)
    {
        edit.Focusable = false;
        edit.FocusableInTouchMode = false;
    }
#endif
}

Update:

Since you can't get the control using DataTemplate, you could disable autofocus for all Pickers for this page using the following code.

void ModifyPicker()
{
    Microsoft.Maui.Handlers.PickerHandler.Mapper.AppendToMapping("MyCustomization", (handler, view) =>
    {
#if ANDROID
        var edit = handler.PlatformView as EditText;
        if (edit != null)
        {
            edit.Focusable = false;
            edit.FocusableInTouchMode = false;
        }
#endif
    });
}

public MainPage()
{
    InitializeComponent();
    ModifyPicker();
}

Best Regards,

Alec Liu.
