Question

In my application I have to validate the EditText. It should only allow character, digits, underscores, and hyphens.

Here is my code:

edit         


        

Answer 1

use this 2 function

public static boolean isdigit(EditText input)
    {

    String data=input.getText().toString().trim();
    for(int i=0;i

pass Edittext variable in these function .. so you can have boolean value.
