So I want to have a keyboard in my app that has emoji just like Whatsapp or Hangouts. How can I do that? I want to leave my key keyboard as it is I just want to add tabs to
In Google Hangout, the emoji button is not on the keyboard (at least on my phone which is already using a third party keyboard), it's inside of the TextEdit box, and so it's part of the application itself (Gabe, I'm talking about the latest Google Hangout on top of KitKat with emoji support, all the current screenshots I found of Google Hangout do not show what I'm seeing on my phone, so this must be a very recent feature).
This is actually pretty easy to do, placing an ImageButton to the right of a TextView inside a RelativeLayout (the RelativeLayout which is made to look like a TextView with a custom background).
Then, it's just a matter of hiding the keyboard when clicking on that ImageButton and replacing it with a panel full of emojis when that happens (like in this open source emoji android keyboard, which is under a creative commons non-commercial license).
