Public Methods

public CharSequence filter (CharSequence source, int start, int end, Spanned dest, int dstart, int dend)

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. Returns the CharSequence that we want 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.

public abstract boolean isAllowed (char c)

Returns whether or not we allow character c. Subclasses must override this method.

public void onInvalidCharacter (char c)

Called whenever we encounter an invalid character.

Parameters

c	the invalid character

public void onStart ()

Called when we start processing filter.

public void onStop ()

Called when we're done processing filter
