Raheem Wilks, 19, was the brother of Leeds United's Mallik Wilks. He was shot near Too Sharps on Gathorne Terrace, Harehills, on 26 January.
His coffin was taken to St Aidan's Church, Harehills, by horse-drawn hearse.
Two men have been charged with his murder and are due to stand trial in October.

The Rev Andi Hofbauer, who led the service, said Raheem "loved life and was a bit of a joker, bit of a clown".
"They [his family] described him as fearless.
"He desperately wanted to be popular and was well-loved amongst his family and friends."
She said the service featured favourite songs chosen by his family and the hymns Amazing Grace and How Great Thou Art.
Following the service, during which his brother Malik delivered the eulogy, Raheem was buried at Killingbeck Cemetery.

Konta, 25, was chasing the biggest title of her career but unravelled against the Polish number three seed after a battling first-set display.
The 11th seed, who has made the world top 10, fought back from 4-2 but could not make it 5-5 after missing a volley.
"I'm very pleased with this week, it was pretty spectacular," said Konta.
"I'm really enjoying my journey and looking forward to matches like this against players like Agnieszka," she added.

Konta became the first British woman for 32 years to make the world top 10 after reaching the final. The last British woman to achieve that before her was Jo Durie in 1984.

In the men's final, Andy Murray secured his fifth singles title of 2016 - and 40th of his career - by beating Grigor Dimitrov 6-4 7-6 (7-2).
After dropping her serve twice in each set, Konta tried to even the scoreline in the second, pushing Radwanska to two break points in the sixth game.
However, Radwanska shot a forehand down the line to save her service game.
Konta held the next with a forehand drop shot, only for her opponent to then serve for the title, firing her only ace of the match.

Konta was well beaten in the end by the world number three, but will officially be a top-10 player on Monday morning and now has a very good chance of qualifying for the season-ending championships in Singapore.
Konta has moved into the eighth and final qualifying position, but has only a 10-point advantage over ninth-placed Slovak Dominika Cibulkova.
There are two qualifying weeks remaining, with Konta now heading to Hong Kong, where she has drawn fellow Britain Naomi Broady in the first round.

Klaas Haytema, 30, pulled the plug on the late-night broadcast, which was relaying a Buddhist sermon, because it was disturbing his sleep.
He told the court that he had been unaware a religious service was taking place near his hotel in Mandalay.
Several foreigners have recently fallen foul of strict laws in Myanmar that protect Buddhist ceremonies.
Delivering the ruling, a judge said Haytema was "clearly guilty" of insulting religion and was "sentenced to three months imprisonment with hard labour".
But he avoided another three months after opting instead to pay a fine of 100,000 kyat ($80) for violating the terms of his visa, which requires tourists to respect local customs.
Haytema, who was also accused of insulting Buddhism by not taking off his shoes when he entered the prayer hall, apologised during previous hearings, according to local media.
Slights against religion are treated with extreme seriousness by the courts and a pious public in Buddhist-majority Myanmar, previously known as Burma.
In July, a Spanish tourist was deported after monks complained about a tattoo of Buddha on his leg, while last year a New Zealand bar manager spent 10 months in jail for "insulting religion" by using a Buddha image to promote a cheap drinks night.
