MVPDemo | basic framework based on MVP architecture encapsulation

Answering my own question after determining a flexible solution:

1. First attempt - get DisplayMetrics of the root View and subtract an arbitrary number to attempt to hit the Keyboard.Key
   • this didn't work because clickXY function uses the position of the view
   • this ended up being the reason for the exception since the view is smaller than the DisplayMetrics values and adding to the Views on screen position would give a very high number for the x and y.

So I tried again,

1. Second attempt - use check method on the ViewMatcher to check the KeyBoardView.
   • by doing so I was able to get access to the KeyboardView's position x
   • then I was able to get the KeyboardView's width and height
   • by performing some math, I was able to figure out target index for x & y

the math:

• take the widthPercent for the Keyboard.Key (in my case 33.3%)
• take the rowCount of the keyboard.xml (in my case 3)
• use (viewWidth * widthPercent) / 4 to get relativeButtonX
• use (viewHeight / rowCount) / 2 to get relativeButtonY
• then for targetY, I took viewHeight - relativeButtonY
• finally, for targetX, I took (viewPosX + viewWidth) - relativeButtonX

So enough explanation, here is the code:
