Android floating action button hidden behind of bottom navigation bar - android

New to android programming & struggling with right now. I'm using android studio's default "Navigation Drawer Activity". On top of that, I've added a Bottom Bar from https://github.com/roughike/BottomBar. But, after adding that my FAB has hidden behind the Bottom Bar.
Here is the Scrrenshot -
I know it's some kind of style issue. I tried to give bottomMargin for FAB. But, it's not working.
Here is my code -
app_bar_main.xml
<?xml version="1.0" encoding="utf-8"?>

Need Some Guidance to solve this.

Add app:elevation="#dimen/text_margin" like this:
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="#dimen/fab_margin"
android:src="#android:drawable/ic_dialog_email"
app:elevation="#dimen/text_margin" /><!--adding this line should resolve your problem-->

Here is a solution that works for our use case. Basically we wanted to hide bottom navigation view and the fab that belongs to it whenever the user scrolls in the screen.
For that purpose we have decided to use the app:layout_behavior="com.google.android.material.behavior.HideBottomViewOnScrollBehavior" that comes out of the box for BottomNavigationView. All that is left is to anchor the fab to the BottomNavigationView and use the same layout_behavior on fab, too.
Here is an example of it:
<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<include layout="#layout/inc_app_bar"/>
<fragment
app:layout_behavior="#string/appbar_scrolling_view_behavior"
android:id="#+id/main_nav_host_fragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:defaultNavHost="true"
android:name="androidx.navigation.fragment.NavHostFragment"
app:navGraph="#navigation/bottom_nav_graph"/>
<com.google.android.material.bottomnavigation.BottomNavigationView
android:id="#+id/main_bottom_nav_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
style="#style/Theme.BottomNavigationView"
app:layout_behavior="com.google.android.material.behavior.HideBottomViewOnScrollBehavior"
app:labelVisibilityMode="labeled"
android:background="?android:attr/windowBackground"
app:menu="#menu/bottom_nav_menu"/>
<com.google.android.material.floatingactionbutton.FloatingActionButton
android:id="#+id/main_fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_anchor="#id/main_bottom_nav_view"
app:layout_anchorGravity="top|end"
android:layout_marginBottom="#dimen/fab_margin_bottom"
android:layout_marginEnd="#dimen/fab_margin_end"
app:layout_behavior="com.google.android.material.behavior.HideBottomViewOnScrollBehavior"
app:srcCompat="#drawable/ic_add_24px"/>
</androidx.coordinatorlayout.widget.CoordinatorLayout>
Other than that you can define your own layout_behavior for fab as explained in GitHub: BlogPosts / android-coordinatorlayout-scrolling-hide-fab-behavior.md too.
I hope that it helps :)

In advance I let other know this solution fits to my needs. I don't need fancy animations(which is ok, but not for my project requirements). What I did is to wrap the main content(FrameLayout), the FAB and the BottomNavigationView inside a RelativeLayout. Again, I think this could be done in a better way, so i'm open to suggestions.

I know the question may seems old, but hope this helps to someone else.

Its just margin issue. Just try to implement this code in your coordinatorLayout
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_marginBottom="?attr/actionBarSize">
<com.google.android.material.floatingactionbutton.FloatingActionButton
android:id="#+id/fab"
style="#style/floating_action_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="#dimen/fab_margin"
android:src="#drawable/ic_add_plus" />
</FrameLayout>
And use this style in your style.xml file.
<style name="floating_action_button">
<item name="android:layout_marginBottom">16dp</item>
</style>
We're just doubling the margin. First BottomNavigationView, and Second the default margin of FAB.

Change your xml as this. Add some more properties to your Floating Action Button.
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_gravity="bottom|end"
android:layout_marginBottom="70dp"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:layout_marginTop="10dp"
android:src="#android:drawable/ic_dialog_email" />

Is it possible to create swipeable toolbar?

I want to create a second toolbar with all the menu items directing to different activities instead of creating a viewpager with different fragments. I tried to look for example online but all the examples I found are related to viewpager with fragments or collapsing toolbar. Is it possible to have a "swipeable" toolbar so that all menu items can be displayed instead of putting some of the items on overflow button? The layout I have right now is as follows. Thank you so much.

You can nest a HorizontalScrollview inside your Toolbar layout:
<android.support.v7.widget.Toolbar
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<HorizontalScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<!-- Buttons -->
</LinearLayout>
</HorizontalScrollView>
</android.support.v7.widget.Toolbar>
I am thinking of using navigationview. The example of its implementation is in this link.
Or you can use the one suggested by mrsegev: use HorizontalScrollview in your Toolbar as it is also a view group.

Overlay on top of toolbar and fab

I want to achieve the following:
Overlay the whole activity with a LinearLayout that is currently not visible and revealed with a CircularReveal animation. It should then look like this. (Also, the Fab should be hidden beneath the semi transparent background of the overlay.)
The screenshot was taken from Android Studio's preview.
But instead it looks like this when testing on my phone.
The toolbar and the fab are above the overlay. I attached my layout below.
I know, I could also solve this with a new activity that is drawn over the previous one with a transparent theme but I would prefer this method as it is easier to work with in the future.

android app crash since fab change

I am getting this error log since I changed a few things at my floating action button (and added another one) :
Here is my code:

android:src="#drawable/ic_lightbulb_outline_white_24dp"
app:tint="#color/white"
app:backgroundTint="#color/colorFABhint"/>
Can somebody please tell me what I did wrong? I guess it has something to do with the color change. Thanks.
This fixed it for me:
1) Declare the XML namespace's at the top of the XML file:
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
2) Declare your Floating Action Button as so:
<android.support.design.widget.FloatingActionButton
android:id="#+id/myID"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
app:backgroundTint="#color/myColour"
android:src="#drawable/myIcon"
I hope that this helps.

AppBarLayout scrolling content below Toolbar

I'd like to have a content area below my Toolbar. Its behavior should be to scroll while scrolling up and to enter immediately while scrolling down. Toolbar should stay on its place without any scrolling.
My layout is like that:

If I put content area above Toolbar I am able to get the desired effect, but obviously it's in the wrong position.
If I put content area below Toolbar nothing scrolls...
If I put content area above Toolbar I am able to get the desired
effect, but obviously it's in the wrong position.
Of course it is in the wrong position since: http://www.google.com/design/spec/layout/structure.html#structure-app-bar
The app bar, formerly known as the action bar in Android, is a special
kind of toolbar that’s used for branding, navigation, search, and
actions.
So, you need to add a CollapsingToolbarLayout and the contents on it.
And:
I'd like to have a content area below my Toolbar. Its behavior should
be to scroll while scrolling up and to enter immediately while
scrolling down, Toolbar should stay on its place without any
scrolling.
To not to scrolling the Toolbar after adding that CollapsingToolbarLayout, you may want to add app:layout_collapseMode="pin" to that Toolbar.
Update:
Since my original suggestion did not work, another method to achieve the desired outcome would be to break out the Toolbar from the CoordinatorLayout. You can structure your layout XML as follows:
<?xml version="1.0" encoding="utf-8"?>

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/text_search_category"

android:src="#drawable/ic_add_white_24dp" />
</android.support.design.widget.CoordinatorLayout>
</LinearLayout>
If it's still not working, you should consider not using the include statement as this might be the source of the issues. Rather, bring in the layout definition directly into this layout and place under a NestedScrollView (apply app:layout_behavior="#string/appbar_scrolling_view_behavior" to this NestedScrollView). If you need additional help, post the contents of your content_main layout XML in your OP.
Original Response:
Make sure you define the app:layout_behavior for your main content, which defines that the scrolling of the main content should affect the AppBarLayout. Specifically, try this:
<include layout="#layout/content_main"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />

Bottom navigation bar hides on trying scroll

I have Activity with bottom navigation bar (via roughike BottomBar library). It's look like this:
When i'm trying to scroll page, bottom bar hides automatically. So, I get this:
I want avoid this effect. I do not want hide bottom bar when I'm just trying to scroll content but all content lies on screen.
But if page contains content more than one screen then bottom bar must hides on scroll (and now it's works fine).
My code doesn't have any listeners for scroll and my xml file looks like this:

I'm looked for solution for my problem but found nothing. What can i do for avoid this effect?
UPDATED:
FAB is inside ViewPager. Layout for tab on screenshot look like this:
<?xml version="1.0" encoding="utf-8"?>

app:bb_behavior="underNavbar"
You have an issue in the following code
<com.roughike.bottombar.BottomBar
android:id="#+id/bottomBar"
android:layout_width="match_parent"
android:layout_height="60dp"
android:layout_gravity="bottom"
app:bb_tabXmlResource="#xml/bottom_bar_tabs"
app:bb_activeTabColor="#color/white"
app:bb_inActiveTabColor="#color/bottom_bar_inactive_tab"
app:bb_inActiveTabAlpha="1"
app:bb_behavior="shy|shifting" />
replace the
app:bb_behavior="shy|shifting"
with
app:bb_behavior="underNavbar"
Hope this works for you!
Check your manifest FILE and make sure you're not using full screen theme...However, you can use the following code to hide and show the bar on android higher than API 19. To hide the bar, just change VISIBLE to GONE, and make sure you call the showNavBar() method in both your onCreate() and onResume() method
public void showNavBar() {
View view = getWindow().getDecorView();
view.setSystemUiVisibility(View.VISIBLE);
}
I had the same issue, I fixed it by doing this:
In activity_main.xml add this to the CoordinatorLayout:
android:fitsSystemWindows="true"
The viewpager should be like this:
<android.support.v4.view.ViewPager
android:background="#color/colorPrimary"
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
And in all your Fragments, they should start with NestedScrollView and must contain (fillViewport):
<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/constraintLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
tools:context="com.khan.junaid.phonefans.MainActivity">
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/fans_list_view"
/>
</android.support.v4.widget.NestedScrollView>
These settings will make the fragments scrollable, and the content will no more be hiding behind the Navigation bar buttons.
