I am trying to use androids CoordinatorLayout and FrameLayout. What I want to have is a
toolbar
LinearLayout showing some info
tablayout
listviews
when the listviews are scrolled the toolbar and the LinearLayouts should scrollup and hide and the tabs should go at the top.
I have a layout of the type:
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"

</LinearLayout>
</LinearLayout>

<!-- My Scrollable View -->
<include layout="#layout/nested_scrolling_container_view"/>
</android.support.design.widget.CoordinatorLayout>
</android.support.v4.widget.DrawerLayout>
What I want to do is have a picture as the background for the entire activity, but what I see is that the AppBarLayout part is always dark. Please help.
I could do it programmatically by setting the backgroundColor in code to Color.TRANSPARENT.
appbar.setBackgroundColor(Color.TRANSPARENT);

This works great. Using Tabs with ListView on each tab, etc.
But, at the bottom of the screen, I want to add a row of TextViews that contain different status info. (e.g. Time since start, Counts, etc.) So I put a LinearLayout at the bottom of the XML. And added a few TextViews. It shows in Design View in Studio. But at the TOP. But when I launch the App on my phone, I don't see it anywhere.
So in short, how do I work with this XML (CoordinatorLayout) to add such a 'status bar' to my view at the bottom of the screen?
Use a RelativeLayout as the first child inside the CoordinatorLayout. Have the property android:layout_height="wrap_content" and android:layout_alignParentBottom="true" to the TextViews. The rest, i.e. ViewPager and TabLayout can remain as they are.

I want to use the CoordinatorLayout in one of my activities.
The layout of the activity contains a Toolbar in the top, a RecyclerView in the middle, and a RelativeLayout at the bottom (the footer).
I would like to hide the Toolbar and the footer when the user swipes up the RecyclerView.
What I achieved so far:
When I swipe up, the Toolbar hides, but the footer (which was hidden before) reappears. I want the Toolbar and footer to be linked somehow, so that they hide at the same time when the user swipes.
I've heard about Behaviors but I don't know how to create them (I'm just using the default one).

How to place a layout below toolbar in collapsing toolbar layout?
but it has a relative layout that is not too long. Mine will be long,so i want to put my layout in scroll view.
The code i have tried shows my scrollview,but it does not scroll it,instead it collapses the toolbar.

You could try adding these two lines in your code:
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
>
<Your code here with
app:layout_behavior="#string/appbar_scrolling_view_behavior">
</android.support.v4.widget.NestedScrollView>
Can you try to add this tag
app:layout_behavior="#string/appbar_scrolling_view_behavior"
<ScrollView android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/trial"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
xmlns:android="http://schemas.android.com/apk/res/android">
----- your code
</ScrollView>
AppBarLayout also requires a separate scrolling sibling in order to know when to scroll. The binding is done through the AppBarLayout.ScrollingViewBehavior class, meaning that you should set your scrolling view's behavior to be an instance of AppBarLayout.ScrollingViewBehavior. A string resource containing the full class name is available.

everyone. I'm doing an android app and I'm trying to replicate some of the facebook messenger behaviors. My activity has a coordinatorlayout, inside a tableyout and a viewpager. It's working fine but in a fragment I have a recyclerview inside a nestedscrollerview. Specifically some views, a textview then the recyclerview, I'd like that when scrolling down when it reaches the text above the reyclerview, this text stays anchored in the top and it never gets hidden by the nestedscrollview. Just like the facebook messenger app, like this:
facebook1
facebook2
I thought about having a hidden textview outside of the nestedscrollview that becomes visible when the scrollview reaches the other textview, so it looks anchored but I wanted to know if there is a better way of doing this. Thank you.
Here's a simplified version of the code:
Activity's layout:
<android.support.design.widget.CoordinatorLayout

app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
<android.support.design.widget.TabLayout

app:tabGravity="fill"/>
</android.support.design.widget.AppBarLayout>

<!-- I need this textview to be anchored when it's reached by the scrollview -->
<TextView

android:layout_height="wrap_content"/>
<android.support.v7.widget.RecyclerView

I'm new to Android development and I'm facing the following issue.
This is the layout of my main activity:
<?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.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar_main"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:elevation="4dp"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:layout_scrollFlags="scroll|enterAlways">
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:tabIndicatorColor="#color/white"
app:tabTextColor="#color/selected_text"
app:tabSelectedTextColor="#color/white"/>
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/main_pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
</android.support.design.widget.CoordinatorLayout>
For each tab in the ViewPager I have a fragment, and this is the layout of one of them
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#color/colorPrimary"
android:id="#+id/linear_layout"
tools:context=".fragments.Reviews">
<RatingBar
android:id="#+id/review_totalRating"
style="?android:attr/ratingBarStyle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:numStars="5"
android:stepSize=".5"
android:isIndicator="true"
android:progressTint="#color/golden"
android:layout_gravity="center"
android:paddingTop="10dp"
android:paddingBottom="5dp" />
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:divider="#android:color/transparent"
android:dividerHeight="8dp"
android:paddingLeft="8dp"
android:paddingRight="8dp"
android:id="#+id/listView_reviews" />
</LinearLayout>
Then I populate my ListView with items whose layout is defined in another xml file. My problem is with the ViewPager layout_height: it is now set to match_parent, but the element extends over the bottom of the screen, with the result that the last element of the ListView is covered by the navigation buttons.
This is what I see in the design editor
ViewPager overflow
How can I make the element stop before the navigation buttons?
I faced this issue too. It's because of AppBarLayout behavior in CoordinatorLayout. By default when you create a project from a template it will set up layout with hiding Toolbar. You can run your example and check it - just swipe toolbar up and it will hide and ViewPager will move up and then correctly sticks to the bottom of the screen.
It's not a solution for some cases so you can disable this behavior by removing app:layout_scrollFlags attribute from your Toolbar. After this, the toolbar will become unhideable and the ViewPager will calculate own height correctly.
I solved using a LinearLayout as the only child of the CoordinatorLayout, so everything else becomes a children of the LinearLayout. It seems to me to be just a simple workaround, not a final solution, but now it works. This is now the layout of my main activity:
