How do I ensure that the IME show/hide results in a call to View.onSizeChanged()

Question

Hi

I have a View implementation whose parent layout is a ScrollView. I would like to be called back when the IME is shown/hidden so that I can resize the View accordingly. I understand that onSizeChanged() should be called each time the IME is shown or hidden, but in my code this is not happening.

I've written a test application in order to get the functionality I'm after, and it contains:

• A Button to toggle the IME (show/hide).
• A ScrollView containing several TextViews.

When I click on the button (in this test app), then the IME is shown and the ScrollView is resized accordingly. This is the behaviour I want. I note that in the test app, the ScrollView's onSizeChanged() gets called by the framework requesting a layout, and then an invalidate() to redraw the screen. This behaviour is missing in my incorrectly-functioning application; there is no call to the ScrollView's onSizeChanged() or to my implemented View's onSizeChanged().

My manifest contains the android:windowSoftInputMode="adjustResize" attribute, and I've also added isScrollContainer="true" to the ScrollView's attribute in the layout xml, but this doesn't appear to make any difference.

Could someone please suggest what it is that I could look at in order to get the onSizeChanged() callback in my View?

Apologies if this offends anyone, but by posting here (with appropriate tags) I believe that the android team will see it and hopefully provide some assistance.

Answer 1

The issue is that I've used the FULL_SCREEN Window flag. That flag and adjustResize are 'incompatible' it seems.

This came up in August last year:

Presumably, this is a defect and so I'll get around to raising an issue.
