Remove filter from EditText in Android?

It is possible to add filters in Android by doing something like this to add a 3 char limit to the field:

editText.setFilters(new InputFilter[] { new InputFilter.LengthFilter(3) });

What about removing an already set filter though? My problem is I will be switching between a 3 and 4 character max length on the field depending on a selection by the user. Just running the above code feels like it would generate alot of extra work for the GC.

I could of course add a couple of instance variables that correspond to each filter and just add them when needed and then I would only have the two filters which is fine for this case. It would be interesting to know if it is possible to completely remove a filter though. Perhaps by passing in null?

Solution

  • If you do want to just remove filters, rather than replace one with another, you can do it with

    editText.setFilters(new InputFilter[] {});
