Set max length for EditText

Question

I want to set a 1 character length in EditText but just in one part of condition. There is a way to set max length via XML but this will be applied for the whole condition. How to set max length programmatically?

Answer 1

public void setEditTextMaxLength(EditText editText, int length) {
      InputFilter[] FilterArray = new InputFilter[1];
      FilterArray[0] = new InputFilter.LengthFilter(length);
      editText.setFilters(FilterArray);
  }

Answer 2

You can add this in your XML:

android:maxLength="10"

or programmatically:

EditText editText = new EditText(this);
int maxLength = 3;    
editText.setFilters(new InputFilter[] {
    new InputFilter.LengthFilter(maxLength)
});

Answer 3

In Kotlin, this extension function is handy:

fun EditText.setMaxLength(maxLength: Int) {
    filters = arrayOf(InputFilter.LengthFilter(maxLength))
}

Answer 4

edtTime.setFilters(new InputFilter[]{ new InputFilter.LengthFilter(4) });
