How to make a proper button bar on ICS
<!--
A button bar is a set of buttons at the bottom of an activity.
An example is an AlertDialog with OK/Cancel buttons.
Note that something similar can be accomplished using a
split action bar and text-only action buttons, but this is an
alternate presentation that's often preferred.

Backtick Example Command

This is an example command for Backtick. A Backtick command consists of some executable JavaScript and a bit of metadata in JSON.

Here are the required steps to create a command:

  1. Create a new Gist with a command.js and command.json file, or simply fork this one.

  2. Write your JavaScript in command.js. This will be injected into and executed on the page the user is currently on when they run it.

  3. Add some metadata to the command.json file:

  • name: The name of the command.

Create Callbacks on Android: A Fragment or View makes a Callback to the hosting Activity

Steps to make a Fragment or View to have a Callback to its parent Activity.

Step by step from info taken from here:

http://developer.android.com/guide/components/fragments.html#CommunicatingWithActivity


  • We have an Activity that hosts a Fragment or a View
  • We have a Fragment or View with a ListView or a Button or some element that we want the Activity to know about. i.e. we load detailed info of an element chosen on a ListView or something.
