Android- bottom Navigation bar is long - android

bottom Navigation bar is long seems like a space is excreted, i tried to solve this problem a days.
This is the problem
:
This is the xml code :
<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout

android:src="#drawable/ic_cart"
app:fabCustomSize="72dp"
app:layout_anchor="#id/bottomAppBar"
app:maxImageSize="34dp" />
</androidx.coordinatorlayout.widget.CoordinatorLayout>
This is the menu xml code :
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/home_page2"
android:icon="#drawable/ic_home2"
android:title="Home" />
<item
android:id="#+id/message_page2"
android:icon="#drawable/ic_message1"
android:title="Message" />
<item
android:id="#+id/placeholder"
android:checkable="false"
android:title="" />
<item
android:id="#+id/help_page2"
android:icon="#drawable/ic_help"
android:title="Help" />
<item
android:id="#+id/settings_page2"
android:icon="#drawable/ic_settings"
android:title="Settings" />
I am using coordinator layout so i think coordinator layout is the problem or might be the fragment i used.
what should i do to remove this space (space below bottom Navigation bar that already in picture)?

You could try making the height of the Bottom Bar 100dp.

Android bottom navigation with rounded button

I want to do something like this in my android app.
I tryied with app bar and fab button but was unsuccessful.
Do you have any ideas?
I have created a Bottom navigationView with 5 menu items.
The middle item has no image.
So I added an imageButton(android:clickable="false") inside the bottom navigationView.
<com.google.android.material.bottomnavigation.BottomNavigationView
android:id="#+id/bottom_nav_instructor"
android:layout_width="match_parent"
android:layout_height="56dp"
android:layout_gravity="bottom"
android:background="#color/bg_bottom_nav_bar"
android:elevation="15dp"
app:itemIconSize="30dp"
app:itemIconTint="#drawable/bottom_navigation_colors"
app:itemTextAppearanceActive="#style/TextStyleTab"
app:itemTextAppearanceInactive="#style/TextStyleTab"
app:labelVisibilityMode="labeled"
app:menu="#menu/instructor_bottom_nav">
<ImageButton
android:layout_width="56dp"
android:layout_height="56dp"
android:layout_gravity="center"
android:layout_marginBottom="15dp"
android:background="#drawable/fab"
android:clickable="false"
android:src="#drawable/ico_add" />
</com.google.android.material.bottomnavigation.BottomNavigationView>
to acheive this you need a custom view. You can do this by creating a custom view class with extending BottomNavigationBar.
You can look at this article to try to acheive your desired look for your BottomNavigationBar.

I achieved same UI using Frame layout. Here is the code
<?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:layout_height="match_parent">
<fragment
android:id="#+id/nav_host_fragment"
android:name="androidx.navigation.fragment.NavHostFragment"
android:layout_width="match_parent"
android:layout_height="0dp"
app:defaultNavHost="true"
app:layout_constraintBottom_toTopOf="#id/bottom_navigation"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:navGraph="#navigation/nav_graph_home" />
<com.google.android.material.bottomnavigation.BottomNavigationView
android:id="#+id/bottom_navigation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/background_white_rounded_top"
app:itemTextColor="#color/white"
app:layout_constraintBottom_toBottomOf="parent"
app:menu="#menu/bottom_nav_bar_home_items"
app:labelVisibilityMode="unlabeled">
</com.google.android.material.bottomnavigation.BottomNavigationView>
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintBottom_toBottomOf="parent">
<ImageView
android:id="#+id/toggle_alignment"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_home_scan" />
</FrameLayout>
</androidx.constraintlayout.widget.ConstraintLayout>
and do not give icon for middle item.
<?xml version="1.0" encoding="utf-8"?>
<menu
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"

android:icon="#drawable/ic_four"
android:title=""/>

</group>
</menu>

How to increase distance between items in BottomBar?

I want to make exactly the same, bottom bar with floating action button. I have used standart BottomNavigationView as well as this library, but I can't increase the distance between items. Is there a way to do that?
Add a fifth item to your bottom navigation. Give it an empty string for its label and a completely transparent image for its icon. Also make it disabled. Put this item in the middle position.
The visual effect will be that there's no item in the center of the screen, and the rest of the buttons should be spaced nicely around the floating action button.
this is work for me.
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.design.widget.BottomNavigationView
android:id="#+id/bottom_navigation"
android:layout_width="match_parent"
android:layout_height="?actionBarSize"
android:layout_alignParentBottom="true"
android:layout_gravity="bottom"
android:background="#color/colorAccent" />
</RelativeLayout>
<android.support.design.widget.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#color/colorPrimary"
android:backgroundTint="#color/white"
android:scaleType="center"
app:fabSize="normal"
app:layout_anchor="#+id/bottom_navigation"
app:layout_anchorGravity="top|center_horizontal" />
</android.support.design.widget.CoordinatorLayout>
This worked for me Just add fifth item with:
<item android:title=""/>
This will add extra spaces between items.
Happy coding.
Add 5th item and then disable it programatically
