CUSTOM KEYBOARD

CUSTOM KEYBOARD

Giorgio Sfiligoi 636

I have done a customized soft keyboard, called MyNumericKeyboard, that works nicely in a test environment. Platform: Android.

Now I have to integrate it into a more complex page.

With MyNumericKeboard open, if I tap on another Entry element, it opens its own soft keyboard and the result is two keyboards on the screen. To avoid this, I see two options:

Tapping anywhere forces KyNumericKeyboard to close - I can easily create a method that closes it, but I do not know how to call such method; OR:
MyNumericKeyboard works in a modal fashion, i.e. it disables any other activity until it is closed by means of the button 'Done'.

Any idea?

For the first option, you could try setting HideSoftInputOnTapped, it's of type bool, which indicates whether tapping anywhere on the page will cause the soft input keyboard to hide if it's visible on Android and iOS.

For the second option, it's not clear if you want to add a toolbar over the keyboard and click the done button to hide it.

Option 1: I verified that HideSoftInputOnTapped does its job for a system-generated soft keyboard, but it does not close MyNumericKeyboard, which is generated in my code and activated as follows:

        <Entry Text="{Binding Amount, Converter={StaticResource signedConverter}, Mode=OneWayToSource}"
               x:Name="entryField"
               WidthRequest="300"
               VerticalOptions="Start" HorizontalOptions="Start"
               TextColor="Blue" BackgroundColor="WhiteSmoke"
               IsReadOnly="True">
            <Entry.GestureRecognizers>
                <TapGestureRecognizer Tapped="OnFieldTapped" />
            </Entry.GestureRecognizers>
        </Entry>

        <components:MyNumericKeyboard x:Name="keypad" IsVisible="False" ...

    void OnFieldTapped(object sender, EventArgs e)
    {
        keypad.Init(this.entryField);
    }

keypad.Init makes IsVisible = true;

Option 2: The button 'Done' is included in MyNumericKeyboard, and it makes IsVisible = false; I don't need a toolbar. The idea is: when it is visible, any other activity in the page should be inhibited.

From the code snippets, it's not clear about the <components:MyNumericKeyboard, would you mind sharing more code snippets? And you could try the following to hid keyboard on Android platform

if(Platform.CurrentActivity.CurrentFocus != null) Platform.CurrentActivity.HideKeyboard(Platform.CurrentActivity.CurrentFocus);
