My FAB for some reason won't go to the bottom right corner of the screen as usual. I'm inside a fragment and that fragment is a coordinator layout (I don't know if this is a good practice or not).
Here is the layout xml code:
<android.support.design.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="com.gigstudios.polls.fragment.MyPollsFragment">
<LinearLayout
android:id="#+id/linear_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</android.support.v7.widget.RecyclerView>
</LinearLayout>
<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="#drawable/ic_add_white_36dp"
app:fabSize="normal"
app:layout_anchor="#id/linear_layout"
app:layout_anchorGravity="bottom|right|end" />
</android.support.design.widget.CoordinatorLayout>
And for some reason the FAB ends up in the top right instead of the bottom right. Does anyone know what I'm doing wrong?
Btw the xml preview has always shown the fab button in the bottom right corner but when I run it on my phone it's in the top right instead.
Edit: Here's my main_activity xml to show where I'm putting the fragment (The "container" FrameLayout).

</android.support.design.widget.CoordinatorLayout>
The issue is coming due to android.support.v4.widget.NestedScrollView add one more field android:fillViewport="true". Issue was coming as yourNestedScrollView` was not expanding to match parent or take available space. Working fine tested with my code
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/colorPrimary"
android:fillViewport="true"
android:layout_marginTop="?attr/actionBarSize">
</android.support.v4.widget.NestedScrollView>
Remove the lines
app:layout_anchor="#id/linear_layout"
app:layout_anchorGravity="bottom|right|end"
on your FloatingActionButton. They aren't doing anything (since you are anchoring to a view that fills the entire CoordinatorLayout). This will cause your layout_gravity to be respected and your FloatingActionButton will be placed in the bottom right corner of the CoordinatorLayout.
Remove the android:layout_gravity="bottom|end" from your floating action button xml code...it will work

I can't get the anchor to work. it doesn't follow the app bar being scrolled to the top.

plus, I can't get the minHeight to work, It scrolls all the way to the top.
I want the frame layout to follow the app bar and anchor it but the app bar scrolls but the frame layout doesn't.
the frame_info doesn't follow the appbar when I scroll, as it was
supposed to do. when I scroll SongsListView to the top, the appbar
moves to the top too, but frame_info stays in place
First of all, i don't suggest such a layout. Like i said, make the CoordinatorLayout as the root of the layout.
Also, if you are trying to achieve FrameLayout follow AppbarLayout when scrolling, you'll need to add it inside a NestedScrollView then setting the NestedScrollView:
app:layout_behavior="#string/appbar_scrolling_view_behavior"
To follow AppbarLayout.

I'm trying to implement BottomAppBar where I would handle the navigation of a WebView.

Everything works fine but I want to be able to show and hide the BottomAppBar when the users scrolls down and up respectively just as is the behavior here.
I couldn't find a tutorial on that anywhere so has someone implemented a solution on it?
Try settting app:hideOnScroll without setting app:layout_behavior or app:layout_scrollFlags. And remove the AppBarLayout parent view so the BottomAppBar is just a direct child of the CoordinatorLayout.
HideOnScroll does not work with ScrollView instead, use NestedScrollView.
you can use this, when you wont to hide or show your BottomNavigationView or BottomAppBar add one of this line in your method of Scrolling :
..
int height = bottomAppBar.getHeight();
//Hide
bottomAppBar.clearAnimation();
bottomAppBar.animate().translationY(height).setDuration(200);
//Show
bottomAppBar.clearAnimation();
bottomAppBar.animate().translationY(0).setDuration(200);
..
More Android Layout woes for the android newbie. I have been trying to learn android programming, and for the most part it is easy(ish), the hardest part is the layout. I have a Tab layout right now that is the "home" view, and on that view I need a floating action button. For some reason the floating action button is taking up the entire width of the screen. The button itself is the correct size, however the layout cuts off the bottom of the screen. I have followed a few tutorials and no matter what I do it always takes the entire width cutting off the bottom of my screen. Screenshot attached of it running in an emulator from Android Studio.
The layout is here...
<?xml version="1.0" encoding="utf-8"?>

I am filling the view with Fragments and such, but I don't think that would be the problem. Can anyone see why the FloatingActionButton isn't floating, but instead acting as a full linear layout? Thank you so much for the help.
use coordinate Layout for showing floating action button:
Remove floating action Button from your XML code and your XML code should be like this :
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout 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:fitsSystemWindows="true"
tools:context="info.androidhive.fab.MainActivity">
<include layout="#layout/your_current_layout" /> // your current xml code layout
<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" />
</android.support.design.widget.CoordinatorLayout>
You need tu add the FAB only in the home layout:
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="#dimen/fab_margin"

My main activity has a Toolbar within an AppBarLayout and an include below that:

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/tabs" />
</RelativeLayout>
The issue I am currently running into is that The included layout sits on top of my main layout filling the entire screen. I cannot see the Toolbar because it is being covered. I want the included layout to fill only the area below the toolbar. I've tried placing app:layout_behavior="#string/appbar_scrolling_view_behavior" in both layouts and in the include with no avail. Anyone know what's going on?
Update
The activity being shown is this:
This activity should be shown within this one and with out the app title:
Change the root of your included layout to android:layout_height="wrap_content"
Currently, it is match_parent so it will take the height of the parent filling the entire screen.
You will also want to add to your <include>, android:layout_below="#id/toolbar" to place it below the toolbar. By default, RelativeLayout places Views in the top-left so adding this property will tell it to start your included layout below the toolbar.
Note the last two lines in the below code.
<RelativeLayout 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"
tools:context=".ChronoSwipeViewActivity"
android:layout_width="match_parent"
android:layout_height="wrap_content">
in include tag of main layout
<include layout="#layout/activity_chrono_tab"
android:layout_below="#id/toolbar"/>
EDIT: See Using the Master/Detail template in ViewPager Fragments (download link) for full code
I have a toolbar and a recyclerView. When the layout is first inflated the last item of the recyclerView is out of the scroll-able region of the screen and is therefore not visible. After rotating the item appears. It is apparent that the toolbar is pushing the recyclerView outside the boundaries of the screen. If I add padding to the bottom of the recyclerView with the height of the toolbar the issue is resolved BUT only for the initial inflation of the layout. After rotation I am left with a gap on the bottom of the screen. I'm using sdk 23.
A possible workaround would be to programmatically remove the padding after the very first inflation of the layout. I assume I could use:
onCreateView(){ if (onSaveInstanceState != null) removePadding();}
However, I'd rather not have to do a dodgy work-around.
My app is basically exactly the same as the Master/Detail-flow template supplied in Android Studio, except that I use fragments and a single Activity. There is no such issue in the template.
Any ideas?

snippet of ItemListFragment.java
Toolbar toolbar = (Toolbar) root.findViewById(R.id.toolbar);
toolbar.setTitle("List");
I added:
android:layout_gravity="fill_vertical"
android:layout_marginBottom="?attr/actionBarSize"
to item_list.xml. The issue persists. The first time the layout is inflated it shows the bottom element as expected. After rotating to landscape and back to portrait it leaves a margin the size of the actionBar at the bottom of the screen.
This issue does not happen in the Master/Detail-flow template available in Android Studio and the code for item_list.xml, item_list_twopane.xml and activity_item_list are exactly the same as the code used in item_list.xml, land/item_list.xml and fragment_item_list.xml in my project. Yet, as the attached images show, the preview of the AppBar shows the flexible space in the Android template but not my code.
EDIT: When I click on the reference for "?attr/actionBarSize" in the template it navigates to a different line in android SDK's values.xml, which starts with <declare-styleable name="AppCompatTheme">. The same line of code in my app references a different line starting with<declare-styleable name="Theme">.

You must add
android:layout_paddingBottom="?attr/actionBarSize
Instead of
android:layout_marginBottom="?attr/actionBarSize
This works for me
