Why does my BottomNavigationView is not showing up?

I'm trying to add a BottomNavigationView in my project but don't show up when i run the project.
I'd like to put this on several activities, aswell as Toolbar so i created a class that initialize both of them and extends AppCompatActivity so that my activies using the Toolbar or the BottomNavigationView just have to extends this activity and call the method that initialize it (i don't know if this is the right method to use, if no please tell me). So this work with my Toolbar, but my BottomNavigationView isn't showing up.
This is my NavigationActivity i talked about :
public abstract class NavigationActivity extends AppCompatActivity {
private Toolbar mToolbar;
private BottomNavigationView mNavigationView;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
public void initNavigation(int navigationId) {
mNavigationView = (BottomNavigationView) findViewById(navigationId);
mNavigationView.setOnNavigationItemSelectedListener(new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem menuItem) {
switch (menuItem.getItemId()) {
case R.id.navigation_entrainements:
startActivity(new Intent(getBaseContext(),MenuEntrainementsActivity.class));
break;
case R.id.navigation_nutrition:
startActivity(new Intent(getBaseContext(),NutritionActivity.class));
break;
case R.id.navigation_statistiques:
startActivity(new Intent(getBaseContext(),StatistiquesActivity.class));
break;
}
return true;
}
});
}
public void initToolbar(int toolbarId) {
mToolbar = (Toolbar) findViewById(toolbarId);
mToolbar.setNavigationIcon(R.drawable.baseline_arrow_back_black_18dp);
setSupportActionBar(mToolbar);
getSupportActionBar().setDisplayShowTitleEnabled(false);
mToolbar.setNavigationOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View view) {
finish();
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu,menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.btnHome :
startActivity(new Intent(this,MainActivity.class));
return true;
case R.id.btnProfil :
startActivity(new Intent(this,ProfilActivity.class));
return true;
default :
return super.onOptionsItemSelected(item);
}
}
}
and an exemple of how i'm using it in others activities :
initNavigation(R.id.navigation);
initToolbar(R.id.toolbar);
this is how i implement the BottomNavigationView in my XML files :
<android.support.design.widget.BottomNavigationView
android:id="#+id/navigation"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginStart="0dp"
android:layout_marginEnd="0dp"
android:background="?android:attr/windowBackground"
app:menu="#menu/navigation" />
if you need anything else just ask,
thanks for your help :)
(sorry if i made mistakes i'm not great in english)

I Use this from outside of onCreate mothod.
private BottomNavigationView.OnNavigationItemSelectedListener mOnNavigationItemSelectedListener
= new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
Fragment fragment;
switch (item.getItemId()) {
case R.id.btnHome :
startActivity(new Intent(this,MainActivity.class));
return true;
case R.id.btnProfil :
startActivity(new Intent(this,ProfilActivity.class));
return true;
default :
startActivity(new Intent(this,MainActivity.class));
return true;
}
}
};

onOptionsItemSelected not working

I'm making a navigation drawer that slides into the screen. I did this with this code
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/home" android:title="Home"></item>
<item android:id="#+id/change_event" android:title="Change Event"></item>
<item android:id="#+id/FAQ" android:title="FAQ"></item>
<item android:id="#+id/map" android:title="Map"></item>
<item android:id="#+id/Schedule" android:title="Schedule"></item>
</menu>
Now in the MainActivity.Java, I'm trying to switch between activities with the OnOptionsItemSelected method. I'm trying this with this code.
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.home){
Intent intent = new Intent(MainActivity.this, Home.class);
startActivity(intent);
}
return true;
}
What I want this code to do is when if you open the slide menu and click on the home item, the activity home has to start. This is not working, and I have no idea what I am doing wrong.

You have to add onCreateOptionsMenu
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.your_menu_file_name, menu);
return true;
}

Firebase/DrawerLayout - Logged out for no reason?

I am working on a DrawerLayout, and when I click one of the items to go to a Profile page, it logs me out (I can notice this because I get a NullPointer error for the UserAuth [even though I was authed before clicking this]
Note: I didn't notice this until I tried to modularize my code by adding "initialize" methods and such.
This is the code for the items in the drawerlayout:
private void setupDrawerLayout() {
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
navigationView = (NavigationView) findViewById(R.id.navigation_view);
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override public boolean onNavigationItemSelected(MenuItem menuItem) {
//If Clicked...then get item and go to associated page
switch(menuItem.getTitle().toString())
{
case "Profile":
Log.i("Profile", menuItem.getTitle().toString());
startActivity(new Intent(HomeActivity.this, ProfileActivity.class));
/*case "Share":
startActivity(new Intent(HomeActivity.this, ProfileActivity.class));
case "Settings":
startActivity(new Intent(HomeActivity.this, ProfileActivity.class)); */
case "Logout":
Log.i("Logout", menuItem.getTitle().toString());
FirebaseAuth.getInstance().signOut();
//startActivity(new Intent(HomeActivity.this, LoginActivity.class));
}
menuItem.setChecked(true);
drawerLayout.closeDrawers();
return true;
}
});
}
For some reason even though I'm clicking the "Profile" item, it goes to both the Case for that, AND for "Logout" as can be seen by the Log statements:
I/Profile: Profile
I/Logout: Profile
And then this leads to the Error:
E/UncaughtException: java.lang.RuntimeException: Unable to start activity ComponentInfo{com.netgalaxystudios.timeclock/com.netgalaxystudios.timeclock.Activities.ProfileActivity}: java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String com.google.firebase.auth.FirebaseUser.getUid()' on a null object reference

Inside setupDrawerLayout() under onNavigationItemSelected() you have a switch statement.
In each case of the switch statement use break else all the following switch conditions may execute. Since the last case is to logout, the user might be getting signed out each time the switch statement executes.

How to add back button animation to Hamburger button animation

I am using appcompat v7 and support design 23.1.1.
I want to add back button in the hamburger button animation, when back pressed application will go back to started page.
Now in my application I have hamburger button. When it is pressed in main window (marked with orange rectangle) material navigation opens, selected Home (marked as red rectangle) when the application navigates to selected window there are hamburger (yellow rectangle) button again, and I would like to change it.

If the activity figured in your third picture is a new one, you can just add the follow code in the new activity`s onCreate() method. it may help...
final ActionBar toolbar = getSupportActionBar();
if (toolbar != null) {
toolbar.setDisplayHomeAsUpEnabled(true);
}
If it`s in one same activity, and just different fragments through viewpager, use the Toolbar.setNavigationIcon() to change your up icon.

Custom SwitchPreference not saving value

When I access the PreferenceScreen, I notice that my custom switch is off. Then I turn it on and restart the app. I went back to the PreferenceScreen and the switch went back off. This doesn't happen when I use the default SwitchPreference. I am able to customize the SwitchPreference the way I want it to be, so the only problem is the switch value not saving. I have four files related to a customize SwitchPreference and all of the Preferences are placed in an extension of a PreferenceFragment
SettingsFragment.java
public class SettingsFragment extends PreferenceFragment {
#Override

You're never actually setting or saving the state of the switch. You need to override onBindView to set the initial state of the view, and attach a checked change listener to the Switch (R.id.switch_pref) to listen for changes and persist them into SharedPreferences (you can call persistBoolean to do that).
