Advanced Techniques with Fragment Kotlin Extensions in Java Class Libraries
groovy
dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
}
kotlin
suspend fun fetchData(): String {
// Simulate fetching data asynchronously
delay(1000)
return "Data from server"
}
public final class KotlinExtensions {
public static String fetchData(Context context, Callback callback) {
// Call the Kotlin extension function
String result = MyKotlinLibraryKt.fetchData();
// Pass the result to the callback
callback.onResult(result);
return result;
}
}
kotlin
class MyFragment : Fragment() {
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
return inflater.inflate(R.layout.fragment_my, container, false)
}
}
public final class FragmentHelper {
public static Fragment createMyFragment() {
// Use the Kotlin extension to create the fragment
return new MyFragmentKt.createMyFragment();
}
}
