Android - list of numbers with incrementer decrementer
<p>I want to have a list of numeric EditText fields with incrementers and decrementers (functionally like spin-buttons). The numbers are supposed to be percentages adding up to 100. Finalizing the values should only be possible when this happens. I also want the incrementers to grey out when the total reaches 100 and the decrementers to grey out when the total reaches 0. I'm also including another text view that shows the difference between the current total and 100. What is a good way to do this? Should I just have 2*n different buttons with the listeners doing all this work? Or is there a neater way?</p>

<p><b> Update: </b>
The principal way of changing the values will be the up/down buttons. The text being editable is just for a secondary matter of convenience.</p>
