07-30 16:57:08.613: E/AndroidRuntime(655):
    java.lang.ArrayIndexOutOfBoundsException: length=12; index=-1

这是您需要的主要内容。它表明您有一个大小数组，12但您正在尝试访问元素 number -1。这通常是因为您跑完了数组的末尾（在这种情况下是倒计时）。它在 Android 运行时中，但您会发现您可能需要沿着堆栈跟踪查找错误代码（这几乎总是您的代码）。

很可能是以下行：

for (int i = 0; i < possibleViews.size(); i--)

中getTouchedViews()，堆栈的第三步和似乎是非 Android 代码的第一个：

07-30 16:57:08.613: E/AndroidRuntime(655):  at
    sample.app.touchsample.TouchsampleActivity
        .getTouchedViews(TouchsampleActivity.java:365)

这个循环从零开始并倒计时（立即到-1）所以几乎可以肯定是你的问题。改为使用i++。

错误在于：

for (int i = 0; i < possibleViews.size(); i--)

它应该是：

for (int i = 0; i < possibleViews.size(); i++)

当您尝试访问数组索引之外的元素时，会发生 ArrayIndexOutOfBoundsException。

例如，考虑您的数组有 10 个元素，并且您尝试访问元素 12 或 13，这将导致 ArrayIndexOutOfBoundsException。

再次查看这些循环并查看数组索引超出范围的位置。还要记住java中的数组以0而不是1的索引开始。
