Как сказал Майк М., вы должны поставить Toolbar
вокруг TabLayout
. Затем вы должны сделать следующее в упражнении: Сначала установите панель инструментов как ActionBar с setSupportActionBar()
. Затем получите ActionBar с getActionBar()
и вызовите setHomeAsUpIndicator()
с векторным активом menu
на нем.
Вот мой собственный практический пример в пользу кого-либо еще ищущего этот вопрос (извините демонстрационный текст, это была первая вещь, которую я нашел на Википедия ):
import nltk
import pprint
tokenizer = None
tagger = None
def init_nltk():
global tokenizer
global tagger
tokenizer = nltk.tokenize.RegexpTokenizer(r'\w+|[^\w\s]+')
tagger = nltk.UnigramTagger(nltk.corpus.brown.tagged_sents())
def tag(text):
global tokenizer
global tagger
if not tokenizer:
init_nltk()
tokenized = tokenizer.tokenize(text)
tagged = tagger.tag(tokenized)
tagged.sort(lambda x,y:cmp(x[1],y[1]))
return tagged
def main():
text = """Mr Blobby is a fictional character who featured on Noel
Edmonds' Saturday night entertainment show Noel's House Party,
which was often a ratings winner in the 1990s. Mr Blobby also
appeared on the Jamie Rose show of 1997. He was designed as an
outrageously over the top parody of a one-dimensional, mute novelty
character, which ironically made him distinctive, absurd and popular.
He was a large pink humanoid, covered with yellow spots, sporting a
permanent toothy grin and jiggling eyes. He communicated by saying
the word "blobby" in an electronically-altered voice, expressing
his moods through tone of voice and repetition.
There was a Mrs. Blobby, seen briefly in the video, and sold as a
doll.
However Mr Blobby actually started out as part of the 'Gotcha'
feature during the show's second series (originally called 'Gotcha
Oscars' until the threat of legal action from the Academy of Motion
Picture Arts and Sciences[citation needed]), in which celebrities
were caught out in a Candid Camera style prank. Celebrities such as
dancer Wayne Sleep and rugby union player Will Carling would be
enticed to take part in a fictitious children's programme based around
their profession. Mr Blobby would clumsily take part in the activity,
knocking over the set, causing mayhem and saying "blobby blobby
blobby", until finally when the prank was revealed, the Blobby
costume would be opened - revealing Noel inside. This was all the more
surprising for the "victim" as during rehearsals Blobby would be
played by an actor wearing only the arms and legs of the costume and
speaking in a normal manner.[citation needed]"""
tagged = tag(text)
l = list(set(tagged))
l.sort(lambda x,y:cmp(x[1],y[1]))
pprint.pprint(l)

Я являюсь автором streamhacker.com (и спасибо за упоминание, я получаю изрядное количество кликабельного трафика из этого конкретного вопроса). Что конкретно вы пытаетесь сделать? В NLTK есть много инструментов для выполнения различных задач, но ему не хватает четкой информации о том, для чего использовать эти инструменты и как их лучше всего использовать. Он также ориентирован на решение академических задач, поэтому переводить педагогические примеры в практические решения может быть нелегко.
