    • getInstance

      @Nonnull public static DigitsInputFilter getInstance(@Nullable Locale locale)
      Returns a DigitsKeyListener that accepts the locale-appropriate digits.
    • getInstance

      @Nonnull public static DigitsInputFilter getInstance(@Nullable Locale locale, boolean sign, boolean decimal)
      Returns a DigitsKeyListener that accepts the locale-appropriate digits, plus the locale-appropriate plus or minus sign (only at the beginning) and/or the locale-appropriate decimal separator (only one per field) if specified.
    • getInstance

      @Nonnull public static DigitsInputFilter getInstance(@Nonnull String accepted)
      Returns a DigitsKeyListener that accepts only the characters that appear in the specified String. Note that not all characters may be available on every keyboard.

      Returns a DigitsKeyListener based on the settings of an existing instance, with the locale modified.
    • filter

      public CharSequence filter(@Nonnull CharSequence source, int start, int end, @Nonnull Spanned dest, int dstart, int dend)
      Description copied from interface: InputFilter
      This method is called when the buffer is going to replace the range dstart … dend of dest with the new text from the range start … end of source. Return the CharSequence that you would like to have placed there instead, including an empty string if appropriate, or null to accept the original replacement. Be careful to not to reject 0-length replacements, as this is what happens when you delete text. Also beware that you should not attempt to make any changes to dest from this method; you may only examine it for context.

      Note: If source is an instance of Spanned or Spannable, the span objects in the source should be copied into the filtered result (i.e. the non-null return value). TextUtils.copySpansFrom(icyllis.modernui.text.Spanned, int, int, java.lang.Class<?>, icyllis.modernui.text.Spannable, int) can be used for convenience if the span boundary indices would be remaining identical relative to the source.
