我正在开发一个数学测验应用程序。它由9个级别组成，每个级别包含10个问题，这些问题从数组生成随机操作数。在特定级别，它生成随机操作数，我必须将这些操作数传递到另一个级别。
例如：如果第1级第1个输入是随机的4和3，则第2级第1个输入应该是3和4，同样它应该将所有10个设置操作数传递到另一个级别。我有共享代码。

这是为10个问题生成随机值的一个级别，我想使用在另一个级别中随机生成的相同问题顺序。 例如：
Level 1 input 1: 4 and 3 input 2: 2 and 3 (generates randomly)
Level 2 input 1: 3 and 4 input 2: 3 and 2 (from level 1 input)
答案 0 :(得分：0)
您应该使用一个viewpager来控制滑动并将数据保存到活动级别。比10个不同的活动更容易。
