Stop to show fill dialog if IME is showing

Because the request to show the fill dialog and the IME is asynchronous.
To reduce the fill dialog appearing on the IME, check to see if the IME
shows it before showing the fill dialog.

This change does not fully resolve the IME and fill dialog showing
at the same time but can mitigate the problem. More details see the bug.

When supported fill dialog flag is appended, the view of parameter
will be null. So remove to check the view is not null when appending
the reset fill dialog flag.
