我有两个旋转器，第二个旋转器上的信息基于第一个旋转器选择示例旋转器 1 蛋白质奶制品如果旋转器 1 设置有蛋白质然后旋转器 2 鸡蛋鸡如果旋转器 1 设置有水果然后旋转器 2 苹果橙色
选择的最后一个值 SPINNER 2 ORANGE
现在我想保留 SPINNER1 和 SPINNER2 的最后选择的值，我正在使用 SharedPreferences 来完成此操作，它按预期对 SPINNER 1 FRUITS Position 2 工作，但是对于 SPINNER2，即使位置正确，它也不会设置最后选择的值位置 1 当它被调用时，onStart();它选择数组 APPLE 上的第一个值
任何帮助，将不胜感激
谢谢
