Xamarin.Forms - Why keyboard not hide when switching to another page? - xamarin

Question

The page has no input fields(only one label), but the keyboard does not disappear when you switch to this page. Is this normal behavior? How to make the keyboard not open on a new page? thank
First page xaml
<ContentPage.Content>
<StackLayout x:Name="stackLayout2">
<Label x:Name="code_label" HorizontalOptions="CenterAndExpand" Font="Bold, Micro" TextColor="black" FontSize="19" Margin="15, 30, 15, 0" />
<Entry x:Name="code_field" TextChanged="CodeFieldTextChanged" Keyboard="Telephone" MaxLength="4" Margin="15, 30, 15, 0" />
</StackLayout>
</ContentPage.Content>
First page CodeFieldTextChanged method
private void CodeFieldTextChanged(object sender, TextChangedEventArgs args)
{
if (args.NewTextValue == "3333")
{
Application.Current.MainPage = new HomePage();
}
}
HomePage xaml
<ContentPage.Content>
<StackLayout>
<Label Text="Authorization ok!"
VerticalOptions="CenterAndExpand"
HorizontalOptions="CenterAndExpand" />
</StackLayout>
</ContentPage.Content>
If Application.Current.MainPage = new HomePage(); is replaсed by Application.Current.MainPage = new NavigationPage(new HomePage()); then keyboard disappears, but in the first case keyboard stays

This issue only seems to occur on Android. And what is happening is that you are changing the page without ever hitting "Return" (green Check mark on the Telephone keyboard) so the keyboard does not get dismissed by the OS, so you have to dismiss it manually. Try this:
private void CodeFieldTextChanged(object sender, TextChangedEventArgs args)
{
if (args.NewTextValue == "3333")
{
// Add the following two lines to dismiss the keyboard
Entry entry = sender as Entry;
entry.Unfocus();
Application.Current.MainPage = new HomePage();
}
}
