Android:: Set max-length of EditText programmatically with other InputFilter

Question

I'm using InputFilter like this to allow only alpha and numbers

private InputFilter[] inputFilters = new InputFilter[] { new InputFilter() {     @Override     public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend)     {         for (int i = start; i < end; ++i)         {             if (!Pattern.compile("[ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz1234567890]*").matcher(String.valueOf(source.charAt(i))).matches())             {                 return "";             }         }          return null;     } } }; 

But problem is "android:maxLength" value in xml file is not working with this InputFilter

I think I need code in InputFilter to set max-length of EditText

Anyone has good idea for this?

Thanks

A simple one-liner would be:

myEditText.setFilters(new InputFilter[] { new InputFilter.LengthFilter(10) });  //replace 10 with required length.
