Я пробовал с .getText().clear() и .setText(""), но это не работает. Есть идеи почему? Я пытаюсь очистить текст от всех EditTexts при нажатии NewEventButton. Если у вас есть идея, пожалуйста, добавьте немного кода. Спасибо!
Java:

//Step 2: get data into variables
//Step 2.B: get data and assign
//PROBLEM: If we just extract, the code won't be run because there's nothing to extract yet. We need a conditional.
//SOLUTION: Create a condition for pressing the button, and then extract the variables when the button is pressed.

PS: приложение представляет собой календарь. Пройдя весь код, мне нужны переменные и чтобы добраться до повестки дня. Также поля должны быть очищены.
