Android EditText Set Max Length

Question

I was trying to set the max length of an EditText, but I didn't get success.

I tried like this:

a.setFilters (new InputFilter[] { new InputFilter.LengthFilter (a.Length) });

and I get some errors ( Not at a.Length ).

and like this:

a.setMaxLength ( a.Lenght);

and still some errors.

I think that I forget some headers but that's just a guess.

Metion that I use Xamarin. Thank you in advance.

Answer 1

If you using c# best if you try it like this

MyEditText.SetFilters( new IInputFilter[] { new InputFilterLengthFilter(10) } );

Answer 2

Try

TextView a = new TextView(...);
InputFilter[] filter = new InputFilter[1];
filter[1] = new InputFilter.LengthFilter(10);
a.setFilters (filter);

or Use this in your xml:

android:maxLength="20"
