Importing Packages with Kotlin Android Extensions Not Possible

One possible solution is to migrate Android data binding to generate Kotlin code instead of Java. Currently, the generated code is in Java, which means Kotlin extension functions cannot be used in the XML and cannot be called from Java. However, once the migration is complete, it would be possible to use Kotlin extension functions in the XML, which would be a great improvement.

Kotlin android extensions, packages cannot be imported

It is necessary to either indicate a specific view or use a wildcard.

import view.some_specific_view 

import kotlinx.android.synthetic.fragment_new_movie.* 

While the answer provided above is partially accurate, its incompleteness could lead to confusion.

import kotlinx.android.synthetic.fragment_new_movie.view.*

Kotlin Multiplatform Android Imports won’t resolve

The gradle build script you are using lacks the necessary android definitions. Consider using this functional gradle script as a starting point.

import org.jetbrains.kotlin.gradle.plugin.mpp.KotlinNativeTarget import org.jetbrains.kotlin.gradle.tasks.FatFrameworkTask buildscript < repositories < mavenLocal() maven("https://kotlin.bintray.com/kotlinx") maven("https://dl.bintray.com/jetbrains/kotlin-native-dependencies") maven("https://dl.bintray.com/kotlin/kotlin-eap") maven("https://plugins.gradle.org/m2/") google() jcenter() >dependencies < classpath("org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.50") classpath("com.android.tools.build:gradle:3.5.0") classpath("co.touchlab:kotlinxcodesync:0.1.5") >> plugins < id ("com.android.library") version "1.3.50" id ("org.jetbrains.kotlin.multiplatform") version "1.3.50" >allprojects < repositories < mavenLocal() google() jcenter() mavenCentral() maven("https://dl.bintray.com/kotlin/kotlin-eap") maven("https://kotlin.bintray.com/ktor") maven("https://kotlin.bintray.com/kotlinx") >> group = "com.example.mykmp" version = "0.0.1" apply(plugin = "maven-publish") apply(plugin = "com.android.library") apply(plugin = "kotlin-android-extensions") android < compileSdkVersion(29) defaultConfig < minSdkVersion(21) targetSdkVersion(29) >> kotlin < android() val frameworkName = "mykmp" val ios = iosX64("ios") < binaries.framework < baseName = frameworkName >> sourceSets < commonMain < dependencies < implementation(kotlin("stdlib-common")) >> commonTest < dependencies < implementation(kotlin("test-common")) implementation(kotlin("test-annotations-common")) >> val androidMain by getting < dependencies < implementation(kotlin("stdlib-jdk8")) >> val androidTest by getting < dependencies < implementation(kotlin("test")) implementation(kotlin("test-junit")) >> val iosMain by getting < dependencies < implementation(kotlin("stdlib")) >> val iosTest by getting < dependencies < implementation(kotlin("stdlib")) >> > tasks.create("framework", FatFrameworkTask::class) < baseName = frameworkName from( ios.binaries.getFramework("DEBUG") ) destinationDir = buildDir.resolve("xcode-frameworks") group = "iOS frameworks" description = "Builds a simulator only framework to build from xcode directly" doLast < val file = File(destinationDir, "gradlew") file.writeText(text = "#!/bin/bash\nexport JAVA_HOME=$\ncd $\n./gradlew \$@\n") file.setExecutable(true) > > > tasks.getByName("build").dependsOn(packForXcode) 

Additionally, within the settings.gradle.kts section, the following is present:

pluginManagement < resolutionStrategy < eachPlugin < if (requested.id.id == "kotlin-multiplatform") < useModule("org.jetbrains.kotlin:kotlin-gradle-plugin:$") > if (requested.id.id == "com.android.library") < useModule("org.jetbrains.kotlin:kotlin-gradle-plugin:$") > if (requested.id.id == "kotlinx-serialization") < useModule("org.jetbrains.kotlin:kotlin-serialization:$") > > > > 

It could raise an error message stating that the com.android.library could not be located, if not found.

Following the installation of Invalidate Cache/Restart on Android Studio or IntelliJ, I would suggest it for further usage.

Create XML layouts for Android, Before you begin.

Can Kotlin’s isNullOrBlank() function be imported into xml for use with data binding

The Java code generated by Android data binding is still derived from the XML, but once the migration happens and Kotlin code is generated instead of Java, Kotlin extension functions can be incorporated into the XML, leading to exciting possibilities.

I have a strong feeling that it will happen soon, considering Google’s heavy promotion of Kotlin. However, for the time being, the options available to you are listed below.

Make sure to include an import, as advised by @Uli.

XML doesn’t support the usage of StringKt.isNullOrBlack due to certain reasons.

The code present in Kotlin String.kt is shown below.

@kotlin.internal.InlineOnly public inline fun CharSequence?.isNullOrEmpty(): Boolean < contract < returns(false) implies (this@isNullOrEmpty != null) >return this == null || this.length == 0 > 

The method’s Java generated code is marked as private with the annotation @kotlin.internal.InlineOnly .

The Kotlin function marked as InlineOnly is not accessible to Java code, as its corresponding Java method is marked private. This is important because calling an inline function without inlining it can only be done through Java code.

The inability to call it from Java also excludes its use in data binding, which relies on generated Java code. Remember, if something is accessible from Java, it can be used in data binding. Otherwise, revert to the traditional Java approach.

The desired outcome can be achieved by using TextUtils.isEmpty().

Android – How to close/hide the Android soft keyboard programmatically

You can force Android to hide the virtual keyboard using the InputMethodManager, calling hideSoftInputFromWindow , passing in the token of the window containing your focused view.

// Check if no view has focus: View view = this.getCurrentFocus(); if (view != null)

This will force the keyboard to be hidden in all situations. In some cases, you will want to pass in InputMethodManager.HIDE_IMPLICIT_ONLY as the second parameter to ensure you only hide the keyboard when the user didn’t explicitly force it to appear (by holding down the menu).

Note: If you want to do this in Kotlin, use: context?.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager

Kotlin Syntax

// Only runs if there is a view that is currently focused this.currentFocus?.let < view ->val imm = getSystemService(Context.INPUT_METHOD_SERVICE) as? InputMethodManager imm?.hideSoftInputFromWindow(view.windowToken, 0) >

Excellent answers from Luc and Mark. However, a good code sample is missing. Adding the tags android:focusableInTouchMode=»true» and android:focusable=»true» to the parent layout (e.g. LinearLayout or ConstraintLayout ) like in the following example, will fix the problem.

Nvm, figured it out. you have to specify what view you want or at least put a wildcard so : view.* or view.some_specific_view.
