#那代码这块就有问题了：
public int[] getCurrentItems() {
int[] currentItems = new int[3];
currentItems[0] = wv_option1.getCurrentItem();

if (mOptions2Items!=null&&mOptions2Items.size()>0){//非空判断
currentItems[1] = wv_option2.getCurrentItem()>(mOptions2Items.get(currentItems[0]).size()-1)?0:wv_option2.getCurrentItem();

// mOptions2Items.get(currentItems[0]).size()-1 这个位置肯定越界
}else {
currentItems[1] = wv_option2.getCurrentItem();
}

if (mOptions3Items!=null&&mOptions3Items.size()>0){//非空判断
currentItems[2] = wv_option3.getCurrentItem()>(mOptions3Items.get(currentItems[0]).get(currentItems[1]).size()-1)?0:wv_option3.getCurrentItem();
}else {
currentItems[2] = wv_option3.getCurrentItem();
}

return currentItems;
}
