滚动的电表，类似于家里的电表和水表，也是在之前的pickView 基础修改的，如果有好的方案能够实现类似于这样滚动表的请记得告诉我哦

* 设置初始值

private int a1, a2, a3, a4, a5, a6, a7, a8;

private int[] a = { a1, a2, a3, a4, a5, a6, a7, a8 };

int j = 0;

private int[] getNum() {

while (num % 10 != 0) {

a[j] = num % 10;

Log.d("debug", "a[j]= " + num % 10);

num = num / 10;

Log.d("debug", "num= " + num);

j++;

}

return a;

}

* 初始化表盘上的数字

private void setInitialize() {

getNum();

country1.setCurrentItem(a[0]);

country2.setCurrentItem(a[1]);

country3.setCurrentItem(a[2]);

country4.setCurrentItem(a[3]);

country5.setCurrentItem(a[4]);

country6.setCurrentItem(a[5]);

country7.setCurrentItem(a[6]);

}

}
