Ответ 1
В настоящее время я работаю над проектом и сталкивался с раздвижным меню, я искал googled, но разочарован тем, что никто не дал никаких инструкций или советов о том, как начать делать скользящее меню. Каждый дал ссылку на некоторые Проекты/библиотеки Github, поэтому я решил сделать это сам, и, наконец, у меня есть собственное готовое меню...
Я провел два дня на нем
1. при создании анимаций скольжения
2. при его работе со всеми разрешениями экрана
Его очень легко и просто, как только вы получите представление о Анимациях, я кое-что прочитал, поэтому неразумно заново изобретать Колесо (люди, которые ссылаются в github исходный код скользящего меню), но я считаю, что вы должны хотя бы один раз попытаться сделать свой собственный, чтобы вы поняли, как он работает и функционирует: P
Итак, это изображение того, как мое скользящее меню будет работать

Там вы найдете полное рабочее и функциональное раздвижное меню, и вы можете настроить его в соответствии с вашими требованиями, если у кого-то еще есть проблемы с настройкой, не стесняйтесь спрашивать, я рад помочь вам : )
