Difference between context menu and option menu in android

Hi,

Can you please tell me the difference between context menu and option menu in android? When I click the menu button on the emulator, is that option menu? or context menu? And how to invoke the other menu (not trigger by the menu button)?

Thank you.

Yes.

And how to invoke the other menu (not trigger by the menu button)?

By long-tapping on whatever widget (if any) has a context menu.

What do you mean by "By long-tapping on whatever widget (if any) has a context menu."?I have a ListActivity with a ListView. In my ListActivity, I call 'registerForContextMenu(lv);' but I never get break in my 'onCreateContextMenu' or 'onContextItemSelected'I try click on ListView but nothing happens.

A long-tap is holding your finger down on the screen for 1-2 seconds. In the emulator, it is holding the mouse button down for 1-2 seconds. Note that for a ListView you might have to long-tap on an item in the list, rather than any blank space at the bottom of the list (if any).

The page on UI Guidelines and Menu Design in the Android documentation gives a good explaination of each of the types of menus.

Two line summary:
Options Menu - the menu you see when pressing the 'Menu' button
Context Menu - the menu shown when you press and hold an item.
