可能重复：
ToggleButton state change programmatically rather than automatically in Android?
我正在尝试切换图像，一个带有切换按钮的数组。唯一的问题是我需要在三次滚动后重置切换按钮。我已经弄清楚如何在3次滚动后重置图像;但是，我必须单击两次切换按钮才能获得与切换按钮中的图像匹配的状态。我正在阅读this thread，但是当我尝试将setActivated（false）应用于循环时，我收到此语法错误：
The method setActivated(boolean) is undefined for the type ToggleButton
按钮的XML：
