title: android: can I find view by its text?
body: <p>In my program I have dynamic buttons each representing a letter and I need to find a button that 
  has a specific letter. Since the buttons' text change from time to time, I cannot use findViewById method, instead i need a way of finding view by its text. Is there one?</p>
  
  <p>If not, suppose the button that has the letter I am searching for has id = B12 and I can get the number 12 in my program. How do I convert number 12 into R.id.B12 ?</p>
