How to search a character from a string android
<p>I have 3 widgets on my screen, Text View, Edit Text and a Button. What ever I insert in my edit text, when I click the button, the text view gets the string from the edit text. Now, what I want to do is that, if I have already inserted the character "\" or "," or what ever character I want, it will not be inputted anymore. It's like, you can only put that character once in the edit text. Do you guys have any idea about it?</p>

<p>Well what I am thinking is that, I have to search from the edit view then validate it. But I don't know what code to use. Could somebody please help me? Thank you!</p>
