Method Detail

tokenize

public static Rfc822Token[] tokenize(CharSequence text)

This constructor will try to take a string like "Foo Bar (something) <foo\@google.com>, blah\@google.com (something)" and convert it into one or more Rfc822Tokens. It does *not* decode MIME encoded-words; charset conversion must already have taken place if necessary. It will try to be tolerant of broken syntax instead of returning an error.

findTokenStart

public int findTokenStart(CharSequence text,
                          int cursor)

Returns the start of the token that ends at offset cursor within text.

Specified by:

findTokenStart in interface MultiAutoCompleteTextView.Tokenizer

findTokenEnd

public int findTokenEnd(CharSequence text,
                        int cursor)

Returns the end of the token (minus trailing punctuation) that begins at offset cursor within text.

Specified by:

findTokenEnd in interface MultiAutoCompleteTextView.Tokenizer

terminateToken

public CharSequence terminateToken(CharSequence text)

Terminates the specified address with a comma and space. This assumes that the specified text already has valid syntax. The Adapter subclass's convertToString() method must make that guarantee.

Specified by:

terminateToken in interface MultiAutoCompleteTextView.Tokenizer
