setOffset 方法没有作用

版本1.5.5 1.5.6
TimePicker
使用下面这个方法除了设置1时为1条,其他的时候都是5条,这是bug,还是使用的姿势不对
/**
* 设置选项偏移量，可用来要设置显示的条目数，范围为1-5。
* 1显示3条、2显示5条、3显示7条……
*/
public void setOffset(@IntRange(from = 1, to = 5) int offset) {
this.offset = offset;
}

Start by tracing TimePicker.setOffset(int) and where its offset value is used to determine the visible item count. Reproduce the behavior for offsets 1 through 5 on versions 1.5.5 and 1.5.6, then verify that the displayed row count matches the documented mapping.
