*Customer Description
I am programmatically entering text into a bunch of Entry controls in a ContentPage. I don't want the keyboard to show since the user isn't supposed to type into them - the text comes from a different async service. But I do want the blinking cursor to show as visual feedback.

*Possible Issues

It seems that by default the OnFocusChangeRequested implementation based on dotPeek decompilation seems that it will show the keyboard within the Focus() event. Thus overriding it would need to happen and specify that you hide it instead or do nothing.

internal override void OnFocusChangeRequested(object sender, VisualElement.FocusRequestArgs e)
bool isFocused = this.Control.IsFocused;
base.OnFocusChangeRequested(sender, e);
if (e.Focus)
if (isFocused)
InputMethodManager inputMethodManager = (InputMethodManager) Forms.Context.GetSystemService("input_method");
inputMethodManager.ShowSoftInput((Android.Views.View) this.Control, ShowFlags.Forced);
inputMethodManager.ToggleSoftInput(ShowFlags.Forced, HideSoftInputFlags.ImplicitOnly);
if (!isFocused)
KeyboardManager.HideKeyboard((Android.Views.View) this.Control);

However when trying to override

protected override void OnFocusChanged (bool gainFocus, Android.Views.FocusSearchDirection direction, Android.Graphics.Rect previouslyFocusedRect)
base.OnFocusChanged (gainFocus, direction, previouslyFocusedRect);

It seems it is never actually hit within code when added to an EntryRenderer, and thus not able to intercept the method above.




Attached as XTest.zip - Displays multiple entry fields calling the .Focus event to which the SoftKeyboard displays even when trying to force it to hide.

There is currently no supported method to do this with Xamarin.Forms.
Comment 3 Bryan Hunter 2016-04-08 19:33:44 UTC
Thank you for your report. It appears the custom renderer workaround posted on Forums (http://forums.xamarin.com/discussion/comment/142567/#Comment_142567) addresses the issue. At this time there are no plans to implement changes around this issue.

Warm regards,
