Why

I'm thrifty, with an LG Optimus V in my hand. It's got a 3.2" screen which makes typing on the standard Android keyboard a frustrating process. So I'm modifying the SoftKeyboard sample project, and experimenting with ways to arrange the keys differently such that they can be made larger.

View screenshot.png for a preview. Though, it's slightly out of date from what I describe below.

Ideas

The stock keyboard contains as many as 10 keys on a row. This is too many for my fingers to handle, so this project has only 7 keys per row.

To do this, I've doubled up on some letters. "q" and "w" are on the same key, same for "ui", "op", "as" and "kl". Long-press those (longer than 200ms) to get the secondary letter. Also, the "#" switches to symbols.

Just for the record: Also thought of having 2 spacebars, normal that obeys most logical completion, and another that ignores and leaves word as typed.

To Do

  • The suggestions portion of the UI needs some major love. Copy style from built-in android keyboard
  • Use long-press codes as a tree of possible predictions ... to maximize effectiveness of condensed keys

Done For now

  • Finish modifying layout of the symbols keys.

Nah

  • Try the alternative method of accessing keys that are hidden by the right side of the screen.

Bugs

  • Suggestions should backtrack to the previous word characters (regex) and them use that for suggestions, not the letter you just typed after backspacing.
  • Backspace should operate from current cursor position. There are edge cases where it doesn't.

Building

Follow the instructions here for existing projects:

Notes

Example project had some quirkiness. Namely regarding the caps lock key. Or maybe I introduced those bugs. Either way:

Thinking that when the keyboard first shows, it should check the shift key state for the current input control (view?). I have an internal boolean for isShifted, which I should set to the cursor shift key state.

Image Transition

ImageTransition is a small android library to transition between a circular ImageView from one Activity to a rectangular ImageView in the launched Activity.

Animations

IconHandler

Handles the drawable binding and position on View, EditText, ImageView or TextView. Also can change the icon color, alpha and size using a SelectorDrawable.

Randomizer

This is mainly core java project. It solves the problem of valid and meaningful random data generation in code flow itself (rather than parsing some random data file and loading data into some list).

It can use existing class models and generate wide range of preexisting random data to test data intensive application in absence of APIs.
