The M2 (starting from the version 1.1.0-alpha06) and M3 have the implementation of ExposedDropdownMenu based on ExposedDropdownMenuBox with TextField and DropdownMenu inside. Something like: val options = listOf(“Option 1”, “Option 2”, “Option 3”, “Option 4”, “Option 5”) var expanded by remember { mutableStateOf(false) } var selectedOptionText by remember { mutableStateOf(options[0]) } ExposedDropdownMenuBox( expanded = expanded, … Read more
This is one of my favourite things to fix in Gradle, and really shows off the flexibility that’s possible (as well as demonstrating why Gradle can be complicated!) First I’ll give a bit of background info on the subprojects {} DSL, then I’ll show how to fix your script, and finally I’ll show the best … Read more
Simply. For me just change this gradle plugins from 1.7.10 to 1.8.0 Then sync. => invalidate caches => build From: plugins { …. id ‘org.jetbrains.kotlin.android’ version ‘1.7.10’ apply false } To: plugins { …. id ‘org.jetbrains.kotlin.android’ version ‘1.8.0’ apply false }
In Kotlin, if statements are expressions. So the following code is equivalent: if (a) b else c The distinction between expression and statement is important here. In Java/C#/JavaScript, if forms a statement, meaning that it does not resolve to a value. More concretely, you can’t assign it to a variable. // Valid Kotlin, but invalid … Read more
I came accross this answer while having the same issue with Kotlin and gradle. I wanted to package to get the jar to work but kept on pilling errors. With a file like com.example.helloworld.kt containing your code: fun main(args: Array<String>) { println(“Hello, World!”) } So here is what the file build.gradle.kts would look like to … Read more
To answer your question: you retrieve the Application from the LocalContext object: val context = LocalContext.current val application = context.applicationContext as Application However, when using Navigation Compose, you don’t need to manually pass any arguments to your ViewModel. Instead, you can utilize the built in support for SavedState in ViewModels and add a SavedStateHandle parameter … Read more
You need to reuse the same instance of a fragment that you wanted to hide or show. private fun replaceFragment(fragment: Fragment) { supportFragmentManager.beginTransaction().apply { if (fragment.isAdded) { show(fragment) } else { add(R.id.fmFragmentContainer, fragment) } supportFragmentManager.fragments.forEach { if (it != fragment && it.isAdded) { hide(it) } } }.commit() }
verticalScroll wraps the height of the content, and can be stretched to very long, so the scope has Constraints.Infinity for maxHeight constraint. From fillMaxHeight documentation If the incoming maximum height is Constraints.Infinity this modifier will have no effect. That’s why you need to set height explicitly. Consider switching to LazyColumn(which has fillParentMaxHeight() for this exact … Read more
Even though Alex’s solution works, I don’t believe in including 2 additional dependencies (Actuator and Cloud Context) just to be able to do one operation. Instead, I have combined his answer and modified my code in order to do what I wanted. So, first of all, it is crucial that the code is executed using … Read more
Couroutines are overkill for something as trivial as debounce: class DebounceOnClickListener( private val interval: Long, private val listenerBlock: (View) -> Unit ): View.OnClickListener { private var lastClickTime = 0L override fun onClick(v: View) { val time = System.currentTimeMillis() if (time – lastClickTime >= interval) { lastClickTime = time listenerBlock(v) } } } fun View.setOnClickListener(debounceInterval: Long, … Read more
