Android - edittext illusion
<p>I want to change the value of the EditText while typing on the virtual keyboard; my goal is to hide what the user types while displaying another text.  For example if I want to enter "Stack" but displaying "Overf" it's going to be like this: when "S" typed (and hidden in a buffer) it displays "O" then I type "t" and I get "v" etc.  In the end what I see on the EditText is "Overf" but in the buffer I get "Stack".  I tried TextWatcher but it didn't work.</p>
