Android: How to enable/disable option menu item on button click?
(12 answers)
Closed 7 years ago.
I want the options menu with icons from the api level 11 when the menu button is clicked.If it is not possible after api level 10 then please suggest me how can I do this.
Thanks in advance.
The options menu is deprecated as of API 11; use the action bar or a navigation drawer instead. See: http://android-developers.blogspot.com/2012/01/say-goodbye-to-menu-button.html

With JavaFX, is there any possibility to having Combobox with up/down arrows? like follows,
With this article page 11, under "Mouse and Keyboard Support" section, they have mentioned we can derive such a capability with "JideFX Decoration", but how can I do it?
You could use a Spinner together with a ListSpinnerValueFactory for this purpose.

I have two activities with two different layouts.Right now i have to click a button to change to the other layout, but i wanna to swipe on the screen, is that possible?
If you make your two layouts as Fragments, then you can use the ViewPager to swipe between the fragments in the same activity.
