BottomNavigationBar goes down partially when I change fragments - android

I use BottomNavigationBar(bnb) with Navigation(android jetpack). It's a single-activity app. There are 3 fragments. One of them is starting. When I perform the navigation from starting fragment to any outher, bnb goes down for half of it hight. When I go back or perform navigation between not starting fragments everything is ok.

Fatal Exception: java.lang.VerifyError Verifier rejected class due to bad method DataBinderMapperImpl.internalGetViewDataBinding

I'm getting this error on Android 5x but i don't know what it could be the problem. I'm getting the error on the file FragmentDataNewjourneyBindingImpl. So i tracked and the file that is using the FragmentDataNewJourneyBinding is AuthenticationFragment. So it could be either my xml has something wrong or my fragment has.
This is my xml:

This is AuthenticationFragment.kt. I put only the part of the bindingView declaration because i think it's more important:
#ExperimentalCoroutinesApi
class AuthenticationFragment : NavigationFragment() {
val viewModel: AuthenticationViewModel by viewModel()
lateinit var bindingView: FragmentDataNewjourneyBinding
lateinit var formValidate: FormValidate
private val novaJornadaActivity: NovaJornadaActivity by lazy { activity as NovaJornadaActivity }
private val management: TagManagement by inject()
#ExperimentalCoroutinesApi
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View {
bindingView = DataBindingUtil.inflate<FragmentDataNewjourneyBinding>(inflater, R.layout.fragment_data_newjourney, container, false)
.apply {
lifecycleOwner = this#AuthenticationFragment
viewModel = this#AuthenticationFragment.viewModel
}
viewModel.checkUserPromoted((activity as NovaJornadaActivity).userPromoted)
return bindingView.root
}
Is there something wrong with my implementation? I will be glad for anyone for trying to help me

Initiale Fragment in bottom Navigation has duplicated [ANDROID STUDIO]

I make an application android for a school project , and actually i have a problem.
I have create 2 activity (MainActivity and BottomNavActivity), and I try to navigate between them, but the "fragment" home page in my navigation Remain undefined.
I found this tutorial in order to navigate between the fragments
and I added events) :
https://medium.com/#oluwabukunmi.aluko/bottom-navigation-view-with-fragments-a074bfd08711
But, now, I can navigate between my "fragments" BUT my initial "fragment" (the one that appears first when launching the activity), remains, and therefore when changing fragments, it is duplicated.
Here is a video of my problem
My Infos.class
public class Infos extends AppCompatActivity {
private ActivityInfosBinding binding;
//I create my variable
final Fragment frag2 = new ProduitsFragment();
final Fragment frag1 = new EntrepriseFragment();
final Fragment frag3 = new CGUFragment();
final FragmentManager fm = getSupportFragmentManager();
Fragment active = frag1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
binding = ActivityInfosBinding.inflate(getLayoutInflater());
setContentView(binding.getRoot());
BottomNavigationView navView = findViewById(R.id.nav_view);
// Passing each menu ID as a set of Ids because each
// menu should be considered as top level destinations.
AppBarConfiguration appBarConfiguration = new AppBarConfiguration.Builder(
R.id.navigation_entreprise, R.id.navigation_produits, R.id.navigation_CGU)
.build();
NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment_activity_infos);
NavigationUI.setupActionBarWithNavController(this, navController, appBarConfiguration);
NavigationUI.setupWithNavController(binding.navView, navController);
//I add my differents fragments
fm.beginTransaction().add(R.id.nav_host_fragment_activity_infos, frag3).hide(frag3).commit();
fm.beginTransaction().add(R.id.nav_host_fragment_activity_infos,frag1).hide(frag1).commit();
navView.setOnNavigationItemSelectedListener(new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull #NotNull MenuItem item) {
switch (item.getItemId()) {
//My first fragment
case R.id.navigation_entreprise:
fm.beginTransaction().hide(active).show(frag1).commit();
active = frag1;
return true;
//My second fragment (default in video)
case R.id.navigation_CGU:
fm.beginTransaction().hide(active).show(frag3).commit();
active = frag3;
return true;
}
return false;
}
});
}
}

As I mentioned in the comment section, the Navigation Component deals itself with the transactions between the fragments.
Here some tips to set up your BottomNavigation bar, hope it will help you.
First of all your mobile_navigation.xml and fragment XML seems to be good.
I could fix a bit your activity_infos.xml file:
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent">
<fragment
android:id="#+id/nav_host_fragment_activity_infos"
android:name="androidx.navigation.fragment.NavHostFragment"
android:layout_width="match_parent"
android:layout_height="Odp"
app:defaultNavHost="true"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintBottom_toTopOf="#id/nav_view"
app:navGraph="#navigation/mobile_navigation" />
<com.google.android.material.bottomnavigation.BottomNavigationView
android:id="#+id/nav_view"
...
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
...
/>
</androidx.constraintlayout.widget.ConstraintLayout>
Update your Left/Right constraint with Start/End here is why
Add a constraint between the bottom of the id/nav_host_fragment_activity_infos and the id/nav_view, just to be sure the fragment never be hidden by the navbar. It is optional.
Then, your activity could be updated without the FrragmentManager:
public class Infos extends AppCompatActivity {
private ActivityInfosBinding binding;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// When you are using an activity you can directly use this
binding = DataBindingUtil.setContentView(this, R.layout.activity_infos);
// Passing each menu ID as a set of Ids because each
// menu should be considered as top-level destinations.
AppBarConfiguration appBarConfiguration = new AppBarConfiguration.Builder(
R.id.navigation_entreprise, R.id.navigation_produits, R.id.navigation_CGU)
.build();
NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment_activity_infos);
NavigationUI.setupActionBarWithNavController(this, navController, appBarConfiguration);
NavigationUI.setupWithNavController(binding.navView, navController);
}
}
I found this tutorial, it explains step by step, and it may provide more info than my "tips".

Can you please try replacing this with your activity_infos.xml
<?xml version="1.0" encoding="utf-8"?>

For some reason when trying to navigate to the InspectionDetailsFragment the app crashes with the No view found for id 0x7f0900df (com.supercom.myapplication:id/fragment_inspection_details_root) for fragment InspectionDetailsFragment I really have no idea what's wrong, I tried to look up but it seems like I am doing everything correct.
The InspectionDetailsFragment used to have a container fragment for it but I deleted it, maybe that is related to the issue I am getting?

Your rootView is null.
Looking at the stacktrace, you're calling initUI() in onCreate(). It is too early. If your rootView is the usual view as inflated in onCreateView(), you need to call initUI() in onCreateView() after inflation, or onViewCreated(), and actually init rootView before that.

How to start shared element transition between 2 activity?

I just learn about Shared Element in Android and I have one image which one of them in ActivitySplashScreen and one other is into Toolbar and I want to use shared element to move this image from ActivitySplashScreen to ActivityMain
after some search and try to implement that simple way to make this feature don't work on my code, for example:
style.xml:
<style name="AppTheme" parent="BaseTheme">
<item name="android:windowContentTransitions">true</item>
</style>
<style name="BaseTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
...
</style>
ActivitySplashScreen.java:
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash_screen);
ButterKnife.bind(this);
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
Intent intent = new Intent(ActivitySplashScreen.this, MainActivity.class);
ActivityOptionsCompat options = ActivityOptionsCompat.
makeSceneTransitionAnimation(ActivitySplashScreen.this,
app_logo,
ViewCompat.getTransitionName(app_logo));
startActivity(intent, options.toBundle());
finish();
}
}, 3000);
}
ActivityMain.java:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
supportPostponeEnterTransition();
}
and ImageView widget on my ActivitySplashScreen and ActivityMain xml layout:
<ImageView
android:id="#+id/instagram_add_story"
android:layout_width="40dp"
android:layout_height="40dp"
android:layout_marginTop="8dp"
android:layout_marginEnd="16dp"
android:layout_marginBottom="8dp"
android:src="#drawable/img_wizard_1"
android:transitionName="app_logo"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent"
tools:ignore="VectorDrawableCompat" />
this code is not working as well and I'm not sure what exactly problem on that

I can use in this way here is my solution according to your scenario.

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
String imageTransitionName = extras.getString("transition_name");
application_logo.setTransitionName(imageTransitionName);
ActivityCompat.startPostponedEnterTransition(mActivity);
}
}
}
}
Here is the Sample code for SharedElementTransition according to your scenario. Whenever you use some kind of style always write in style file then use it.
Note: import android.support.v7.widget.Toolbar; for ToolBar in Java file. This is working fine.
