有 动画和lvview 的对照表么 大神
在android7.0中经常出现内存泄漏,这个是因为没做适配嘛?

Hello sir
The "LVEatBeans" it looks similar to pacman.So if am adding it to my application does it cause any copyright or trademark issues
fun search(list: List, x: Long): Int {
var low = 0
var high = list.size - 1
while ((list[low] < x) && (x < list[high]))
{
var mid = (low + ((x - list[low])*(high - low))/(list[high] - list[low])).toInt()
if (list[mid] < x)
low = mid + 1
else if (list[mid] > x)
high = mid - 1
else
return mid
}
if (list[low] == x.toInt())
return low
if (list[high] == x.toInt())
return high
return -1
}
var items = listOf(2, 3, 5, 7, 11, 13, 17)
println(search(items, 1))
//print -1
println(search(items, 7))
//print 3
println(search(items, 19))
//print -1
// *** simplified speed test ***
items = Array(1000000, {0}).mapIndexed { i, _ -> i }
val count = 100
val start = Date()
for (i in 0..count-1) {
search(items, 777777)
}
val milliseconds = Date().time - start.time
println(milliseconds)
// about 4 milliseconds
