I have made this splash screen for my app but im not sure whether is the best option. As it is sleeping the thread when the app is launching. Here is the code, I use navigation components so the weren´t tutorials available. SplashFragment.kt
class SplashFragment : Fragment() {
private lateinit var rootview:View
override fun onCreateView(
inflater: LayoutInflater, container: ViewGroup?,
savedInstanceState: Bundle?
): View {
// Inflate the layout for this fragment
splash()
rootview = inflater.inflate(R.layout.fragment_splash, container, false)
return rootview
}
fun splash(){
Thread(Runnable {
Thread.sleep(500)
findNavController().navigate(R.id.action_splahFragment_to_loginFragment)
}).start()
}
}
Your solution is good, but it is not safe, it will anyways spawn a new Thread
when you call start
and that thread
will sleep
all good so far but you need to call navController
from UI thread, also if user quits the app before 500
milliseconds it will crash.
Here is a solution Kotlin coroutines
way
val mDelayJob: CompletableJob = Job()
//use mDelayJob to cancel coroutine in onStop, so if even user exits before delay, nothing will happen
fun splash(){
CoroutineScope(Dispatchers.Main).launch(mDelayJob){
delay(500)
findNavController().navigate(R.id.action_splahFragment_to_loginFragment)
}
}
