WebView hides soft keyboard during loadUrl(), which means a keyboard cannot stay open while calling javascript

阅读更多关于 WebView hides soft keyboard during loadUrl(), which means a keyboard cannot stay open while calling javascript

The loadUrl() method calls loadUrlImpl() , which calls a method called clearHelpers() which then calls clearTextEntry(), which then calls hideSoftKeyboard() and then we become oh so lonely as the keyboard goes away. As far as I can see all of those are private and cannot be overridden. Has anyone found a workaround for this? Is there a way to force the keyboard to stay open or

Push Listview when keyboard appears without adjustPan

阅读更多关于 Push Listview when keyboard appears without adjustPan

I am trying to create an activity with a listview and a send message at bottom. The problem is that when the keyboard is shown, instead of pushing the bottom content, is just hiding it.

How can I get the height of virtual keyboard in Android? Is it possible? I try to get it from the main window, but it gives me full height of the application. But I want to get the keyboard height.
