The menu from Chromium Android. It can do this:

Notice the press, move, selection, up are finished in one gesture.

I love this design. It significantly improves the efficiency of using an app. So I dig into chromium, extract related code and pack them into this library.

1. Install dependency

   implementation 'xyz.aprildown:chrome-menu:0.0.2'

2. Set up touch listener

   val handler = AppMenuHandler(activity, listener, R.menu.menu)
   val helper = AppMenuButtonHelper(handler)
   btn.setOnTouchListener(helper)

   listener is an AppMenuPropertiesDelegate interface or use its abstract version AbstractAppMenuPropertiesDelegate()

3. Handle click events

   All events are sent to activity's onOptionsItemSelected. So override it in the activity.

   From 0.0.2, click events are handled in the listener's onMenuItemClicked

4. Check the sample for more customization.

• Change menu width

  Add this line to dimens.xml:

  <!-- 256dp is the original width -->
  <dimen name="menu_width">258dp</dimen>

If you wish to try to the original version from chromium, check out the from_chrome tag. After this tag, I've been adding extra code to make this library easier to use.
