问题 I have a TableLayout that fills_parent inside of a ScrollView. Everything works perfectly except when the Soft Keyboard is shown it obscures the last few EditTexts. Technically, the screen can't be scrolled down any more since without the Keyboard showing, the screen fits all the content. It's just that when the Keyboard is showing, I can not scroll lower to see the remaining EditTexts without hiding the keyboard and allowing the user to just select and enter values into one of the lower

I'd like for the Label or Title of that activity to display the selected model of equipment. It looks like in java to be as simple as setTitle(string), but this functionality doesn't seem to exist in mono. Looked at this, but you can only use integer or an existing drawable. I need to set it to a string. 回答1:

问题 I followed the example in the PushSharp repository at: PushSharp Android Client Sample Everything is working great if the app is open or in the background (by hitting home or back button).

My assumption was that since the PushHandlerService is marked as a [Service] that it would remain open even when the app is closed and continue to listen for notifications. Is there a way to continue
