I am building an app which is supposed to have an activity with fragments inside.
The overall display works but when I try to show a loading screen, it's never displayed. When I am taping on the top bar, it supposed to display another fragment but this one do not appear. I realize that the new fragment is displayed below the current layout.
here is the layout:
<?xml version="1.0" encoding="utf-8"?>

</androidx.drawerlayout.widget.DrawerLayout>
</layout>
the behavior I expect is to be able to load the loading screen and for now, I am using:
homeScreenBinding.loading.visibility = View.VISIBLE
and
homeScreenBinding.loading.visibility = View.GONE
nothing shows up.
Same for the list I am supposed to display when taping on toolbarTitle . I did the code below
homeScreenBinding.toolbarTitle.setOnClickListener {
if (savedInstanceState == null) {
homeScreenBinding.selectVehicleLayout.visibility = View.VISIBLE
replaceFragment(VehiclesListFragment(), R.id.select_vehicle_layout)
}
}
The fragment appears but it's like below the homelayout
the replaceFragment is defined as:
fun AppCompatActivity.replaceFragment(fragment: Fragment, container: Int) {
val className = fragment.javaClass.name
// supportFragmentManager
// .beginTransaction()
// .replace(container, fragment, className)
// .addToBackStack(className)
// .commit()
supportFragmentManager.commit {
replace(container, fragment, className)
addToBackStack(className)
}
}
I put some logs and I saw that clicks are catch and that we access the fragment. it's like anything which is supposed to be displayed on top of the DrawerLayout or homeLayout can't be displayed.
here is the loading layout
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/transparent_black">
<ProgressBar
android:id="@+id/progressBar"
style="?android:attr/progressBarStyleLarge"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"/>
</androidx.constraintlayout.widget.ConstraintLayout>
I feel that the issue is coming from the DrawerLayout. When i try to get ride of the DrawerLayout for test, the loading layout shows up
Any idea ? Thanks
From the provided XML layouts, the
main_containeris overplayed on top of the loading_screen; i.e. the loading screen won't be seen as it's behind the main container.To fix this, move the loading screen to be below the
main_container:The code that is commented out should be working:
Instead of the current one.
