So, the collection must be a mutable list.

These methods will use the natural order of the elements and will sort in-place. Val sortCitiesDescending = cities.sortDescending() We can use sort() and sortDescending() methods to sort lists in Kotlin in ascending and descending order, respectively: val sortCitiesAscending = cities.sort() Let’s take a look at how the slice() method works: val sliceListUsingIndices = countries.slice(1.4)ĪssertEquals(4, sliceListUsingIndices.size) val sliceListUsingCollection = countries.slice(listOf(1, 4))ĪssertEquals(2, sliceListUsingCollection.size) 7. Unlike subList(), this method will create a new list with the subset of elements. We can use the slice() method to retrieve part of the list based on indices. Moreover, the Collection interface provides another method to retrieve parts of the list. Let’s have a look at an example to create a sublist: val subList = countries.subList(1, 4) So, any structural changes in the original list make the behavior of the view undefined. The subList() method returns a view of the original list and will change with it. The parameters for the method are used to define a specified range of the list between the fromIndex (inclusive) and toIndex (exclusive). withContext(Dispatchers.We can use the subList() method to retrieve a part of the list. Textview.text =result is never executed in this code after resource obfuscations. Take a look at the following demo code: package import 7.app.AppCompatActivity import android.os.Bundle import import import import _SHORT import .activity_main.* import routines.* import import import import class MainActivity : AppCompatActivity(), CoroutineScope Copy the code

Problem definition - Problem Analysis - Problem resolution Problem definition This article will address this issue from the following aspects Read on to find out how the two are related, and how resource confusion affects coroutine use. After resource confusion processing, the apK package coroutines did not work as scheduled. With the use of Kotlin, coroutines gradually began to be used in our project, but we encountered a problem in our project.
