Answer 1

For Kotlin and without resetting previous filters:

fun TextView.addFilter(filter: InputFilter) {
  filters = if (filters.isNullOrEmpty()) {
    arrayOf(filter)
  } else {
    filters.toMutableList()
      .apply {
        removeAll { it.javaClass == filter.javaClass }
        add(filter)
      }
      .toTypedArray()
  }
}

textView.addFilter(InputFilter.LengthFilter(10))
