val maxEntries = myMap.values.maxOrNull()?.let { maxValue -> myMap.filterValues { it == maxValue } } ?: emptyMap() * the only bad part besides iterating over the map twice. If you want to overcome that, then I think you have to implement your own specific function dealing wi...

在Kotlin中,一个非常好用的特性是:可以直接使用控件 ID 对控件进行操作,而不需要像 Java 中那样先声明控件,使用 findViewById() 来找到控件,然后才能操作该控件。该特性称为Static Layout Import,即静态布局引入。 举个栗子, activity_main.xml中有个TextView,其 ID 为 tv_name&n... ...
