When using a CoordinatorLayout with AppBarLayout on some activities I need the content to be under the AppBarLayout, i.e. the Toolbar is using some transparent color and overlays the content. By default CoordinatorLayout + AppBarLayout arrange things so that toolbar and scrolling content are next to eachother, without any overlapping.
Android developer guides have the documentation on this here and it looks like this (but those flags do not seem to work with Toolbar and appcompat - I tried):
So I need something that looks like on image above, but with all the scrolling goodies provided by CoordinatorLayout + AppBarLayout. And there's no need to use CollapsingToolbarLayout - just this simple one.
Any hints on how to achieve this?
Here's my activity layout.
<android.support.design.widget.CoordinatorLayout
android:id="#+id/top_content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:background="#android:color/transparent"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<include layout="#layout/main_toolbar"/>
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
>
<!-- to be filled by content fragment -->
</FrameLayout>
<android.support.design.widget.FloatingActionButton
style="#style/FabStyle"
android:id="#+id/fab_button"
android:src="#drawable/bt_filters"
/>
</android.support.design.widget.CoordinatorLayout>
I tried this solution, it works.
transparency :
added background to AppBarLayout, and placed scrolling view in layout before AppBarLayout
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#00000000" >
content positioning : extended AppBarLayout.ScrollingViewBehavior by new AppbBarTransparentScrollingViewBehavior overriding onDependentViewChanged() and modifying updateOffset() to offset = 0
#Override
public boolean onDependentViewChanged(CoordinatorLayout parent, View child,
View dependency) {
updateOffset(parent, child, dependency);
return false;
}
private boolean updateOffset(CoordinatorLayout parent, View child,
View dependency) {
final CoordinatorLayout.Behavior behavior = ((CoordinatorLayout.LayoutParams) dependency
.getLayoutParams()).getBehavior();
if (behavior instanceof Behavior) {
// Offset the child so that it is below the app-bar (with any
// overlap)
final int offset = 0; // CHANGED TO 0
setTopAndBottomOffset(offset);
return true;
}
return false;
}
new content's behavior : set behavior on scrolling view
<android.support.v4.view.ViewPager
android:id="#+id/view_pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
layout_behavior="AppbBarTransparentScrollingViewBehavior" />
result : with an ImageView inside a NestedScrollView as scrolling view
If you remove the line
app:layout_behavior="#string/appbar_scrolling_view_behavior"
from the FrameLayout, the content will be overlapped by the Toolbar. Hope that helps.
EDIT: Oh you mention that you need the scrolling goodies, so this isn't really a solution.
Here i tried to give Main Background image to windowBackground and ToolBar/ActionBar Background as a Transparent. Below Style i have specified in manifest. Window background changes can be done as per required.
Style in Menifest

For Anybody who is working on a layout that is using a NavigationDrawer one solution to this is to change that ToolBar/AppBar dynamically when you are rendering that fragment for example. Lets say you are starting from Home.java and want to go to Chats.Java which is a fragment from there and you want to change that toolbar you can do this:
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
switch (item.getItemId()){
case R.id.nav_chat:
toolbar.inflateMenu(R.menu.My_Other_Menu);
toolbar.setTitle("My New Title");
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container, new PaymentFragment()).commit();
break;
}
}
Please not that we have changed the title and also changed the title, menu and also changed the default NavigationIcon to be a back button. However we will also have to change that back button to go back when it is clicked.
This solution is pushes the contents of that Chats.java to be below the ToolBar instead of being covered by it.

I have a MainActivity XML that contains a bottomNavigationView (bar) with 5 tabs. Each tab calls a different fragment. Switching from a fragment with a collapsing toolbar in its XML (labelled A in picture) to a fragment with a plain fragment (labelled B in picture) causes the bottomNavigationView (bar) to hide partially off the screen.
Is there a way of preventing this?

Try to remove
android:fitsSystemWindows="true"
on your CollapsingToolbarLayout.
try
getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
when you switch to tab with collapsing toolbar and
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
when switch to another
Try to put
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
</android.support.design.widget.CoordinatorLayout>
as the root of all the other fragments you are loading from the BottomNavigationView.
If you use a custom toolbar in the profile fragment,you put this code to onCreateView method:
((AppCompatActivity)getActivity()).setSupportActionBar(toolbar);
I had the same problem and this was solved.
Remove android:fitsSystemWindows="true"
from root CoordinatorLayout.
In my app, when user clicks on a contact icon, I want to display contact's information in a slide, that appears from bottom and can be swiped up to cover the whole screen, or swiped down to dissapear.
I tried to use the SlidingUpPanel from umano, but I couldn't make it work as I need, because it was not designed for that.
Is there some library for that?
This is called a BottomSheet in Android. You can create your own bottom sheet simply using a view as a Child of a coordinator layout.
Add to your app build.gradle:
dependencies{
compile 'com.android.support:design:24.1.1'
}
And then use these classes to create your own:
BottomSheetDialogFragment
BottomSheetDialog
BottomSheetBehavior
BottomSheetBehavior.BottomSheetCallback
Here is an overly simplified demo to show how to make a FrameLayout act as a bottom sheet, you can replace the contents of the FrameLayout with a Fragment and pass information to it as needed. (in your case whichever contact was clicked):

I am in a process of changing home activity to include tabs. I use https://github.com/saulmm/CoordinatorExamples as a source. For unknown reason I do not see the tabs in my AppBarLayout. I can see the Fragment content but tab headers are not displayed at all. I use appcompat-v7:23.3.0.

There is a second problem but I will post it in separate question linked to this question.
Update:
It was caused by CoordinatorLayout misconfiguration. I changed:
android:layout_height="150dp"
to
android:layout_height="wrap_content"
and the tabs appeared suddenly.
According to the guidelines of Android and the material design, it is correct to use the coordinatorLayout.
The appBarLayout should be max 256dp and inside we find the toolbar and the views that you need.
If you want the views collapsing insert into collapsingToolbarLayout.
If you want the toolbar expandable will be inserted inside the collapsingToolbarLayout.
The tabLayout often is insert into appBarLayout but out collapsingToolbarLayout.
The sum of views height is equals at appBarLayout height (or use wrap_content for appBarLayout).
This is an example of expandable toolbar with tabLayout, in this case appBarLayout has a fixed height but you can use wrap_content.

I have two questions/problems :)
First: I have implemented a Sliding Tabs Layout. Now the fragment is use for the Tabs get cut off at the bottom:
Fragment gets cut off (FAB is on bottom|right)
Second: When I press the FAB i want to open a new Activity (the FAB is on a Fragment). But when I press it, a blank Activity opens (the acctual Activity has a Layout and is working on its own) and when I press the back button I exit the app.
For the First question: This is a Methode I call in the onCreate of the MainActivity (Where the Sliding Tabs Layout is implemented) (I dont know if you need the code for the ViewPager so I didn't include it, if you need it tell me please):
private void excTasks(){
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(false);
viewPager = (ViewPager) findViewById(R.id.viewpager);
viewPager.setOffscreenPageLimit(4);
setupViewPager(viewPager);
tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);
setupTabIcons();
}
This is the ViewPagerAdapter:
class ViewPagerAdapter extends FragmentPagerAdapter {
private final List<Fragment> mFragmentList = new ArrayList<>();
private final List<String> mFragmentTitleList = new ArrayList<>();
public ViewPagerAdapter(FragmentManager manager) {
super(manager);
}
#Override
public Fragment getItem(int position) {
return mFragmentList.get(position);
}
#Override
public int getCount() {
return mFragmentList.size();
}
public void addFragment(Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
#Override
public CharSequence getPageTitle(int position) {
//return mFragmentTitleList.get(position);
// Wenn man nur Icons will -> return null, sont das obrige verwenden
return null;
}
}
And here I add the Fragments:
private void setupViewPager(ViewPager viewPager) {
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
adapter.addFragment(new NewsFragment(), "NEWS");
adapter.addFragment(new ProfileFragment(), "PROFILE");
adapter.addFragment(new NotificationFragment(), "NOTIF");
adapter.addFragment(new AboutFragment(), "ABOUT");
viewPager.setAdapter(adapter);
}
This is the .xml of the MainActivity:
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"

</android.support.design.widget.CoordinatorLayout>
For the second question:
This is in the Fragment (in the onViewCreated) where I want the FAB (OfferActivity is what should be opened when pressing the button):
//FAB
FloatingActionButton fab = (FloatingActionButton) v.findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
// Click action
Intent intent = new Intent(con, OfferActivity.class);
getActivity().startActivity(intent);
}
});
As said before, the OfferActivity is working fine when displayed in one Tab, so I won't include the code of it.
Here is the FAB xml (inside a RelativeLayout): EDIT: included the whole file
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

Thank you for answering and sorry if this questions got ask already! :)
EDIT: here is the styles.xml and I have included the whole FAB xml
<resources xmlns:tools="http://schemas.android.com/tools">

</style>
The use of layout_baselineAlignBottom attribute is creating problem I think. The app:layout_anchor attribute enables us to specify the layout on which we wish to anchor our floating action button & app:layout_anchorGravity specifies the placement of the anchor. Place the following floating action button xml at the end just before </android.support.design.widget.CoordinatorLayout>.
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="#dimen/fab_margin"
android:layout_marginRight="#dimen/fab_margin"
android:src="#drawable/fab_add"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:baselineAlignBottom="true"
android:clickable="true"
app:backgroundTint="#color/colorPrimary"
app:layout_anchor="#id/viewpager"
app:layout_anchorGravity="bottom|right|end" />
Please note: Floating Action button can only be used in conjunction with Coordinator layout.
Edit: Okay, wrap your Relative layout inside a coordinator layout, and change
app:layout_anchor="#id/viewpager" to app:layout_anchor="#id/listview" in floating action button xml.

You could use that FloatingActionButton with CoordinatorLayout like this:
<CoordinatorLayout>
<AppbarLayout/>
<scrollableView/>
<FloatingActionButton/>
</CoordinatorLayout>
Something like this(you can use SupportLibrary or using it inside the CoordinatorLayout) this is the best way:
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

Hope something got messed up with the value-v21 style.xml.
Try adding the below set of properties in the value-v21 style.xml.
<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowTranslucentNavigation">true</item>
<item name="android:fitsSystemWindows">true</item>
<item name="android:windowDrawsSystemBarBackgrounds">false</item>
and add the below code to the fab fragment.
private int getNavigationBarHeight() {
Resources resources = getResources();
int resourceId = resources.getIdentifier("navigation_bar_height", "dimen", "android");
if (resourceId > 0) {
return resources.getDimensionPixelSize(resourceId);
}
return 0;
}
#Override
public void onCreateView(Bundle savedInstanceState) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
int navBarHeight = getNavigationBarHeight();
findViewById(R.id.base_frame).setPadding(0, 0, 0, navBarHeight);
findViewById(R.id.menu_frame).setPadding(0, 0, 0, navBarHeight);
}
}

Good Luck..!
Try this code :-

I currently have a DrawerLayout in my main.xml. There's a Toolbar wrapped in an AppBarLayout, and then a simple LinearLayout to swap out fragments.
One of the fragments I navigate to, I want it to contain a TabLayout for a ViewPager of fragments. Currently, I have both of these in the fragment's layout file, but this causes a drop shadow to appear between the Toolbar and the TabLayout, which is something I don't want. I also don't want to use setElevation() because it won't work for pre-Lollipop devices.
A possible solution would be to inflate the AppBarLayout from my fragment, so that it holds both the Toolbar+Tabs. However, I'm not really sure how to do this, so any help would be appreciated.
Here is my main.xml file:
<android.support.v4.widget.DrawerLayout 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/drawerLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.lumivote.lumivote.ui.MainActivity">
<android.support.design.widget.CoordinatorLayout
android:id="#+id/rootLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:id="#+id/appbarlayout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar" />
</android.support.design.widget.AppBarLayout>
<LinearLayout
android:id="#+id/flContent"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
</android.support.design.widget.CoordinatorLayout>
<android.support.design.widget.NavigationView
android:id="#+id/navigation"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="#layout/nav_header"
app:itemIconTint="#333"
app:itemTextColor="#333"
app:menu="#menu/navigation_drawer_items" />
</android.support.v4.widget.DrawerLayout>
And here is my fragment's xml file:
<LinearLayout 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"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.alexdao.democracy.ui.candidate_tab.CandidateListFragment">
<android.support.design.widget.TabLayout
android:id="#+id/tabLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/myPrimaryColor"
app:tabMode="fixed"
app:tabGravity="fill"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"/>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#android:color/white" />
</LinearLayout>
You are able to have separate toolbar for each fragment. Its possible to set fragments toolbar as activity actionbar. Example code:
Toolbar toolbar = (Toolbar) v.findViewById(R.id.toolbar);
((AppCompatActivity) getActivity()).setSupportActionBar(toolbar);
It should be possible to have titles, icons and other stuff as well.
With it you can mimic shadow on pre lollipop devices, no matter what you have on them.
I modified the solution given by bleeding182 and got it to work for AppBarLayout as well (to resolve the problem pointed out by bopa).
#Override
public void onAttach(Context context) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
getActivity().findViewById(R.id.appbar).setElevation(0);
}
super.onAttach(context);
}
#Override
public void onDetach() {
super.onDetach();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
getActivity().findViewById(R.id.appbar).setElevation(R.dimen.toolbar_elevation);
}
}
What I did was replace the call to getSupportActionBar() by giving an ID to my AppBarLayout and then calling findViewById() on it and then calling setElevation on its result. Tested on API 23.
I had a similar issue where I wanted a TabLayout just inside of one fragment.
Without changing any other code you can solve this by using onAttach and onDetach inside your fragment with the TabLayout.
#Override
public void onAttach(Activity activity) {
super.onAttach(activity);
// todo add some further checks, e.g. instanceof, actionbar != null
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
((AppCompatActivity) activity).getSupportActionBar().setElevation(0);
}
}
#Override
public void onDetach() {
super.onDetach();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
((AppCompatActivity) getActivity()).getSupportActionBar()
.setElevation(getResources().getDimension(R.dimen.toolbar_elevation));
}
}
Be sure to set the same elevation on your TabLayout and everything works fine! ;D
You can simply add TabLayout programmatically from Fragment in wich you need TabLayout
tabLayout = (TabLayout) inflater.inflate(R.layout.tablay, null);
appBarLayout = (AppBarLayout) getActivity().findViewById(R.id.appbar);
appBarLayout.addView(tabLayout, new LinearLayoutCompat.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
and remove TabLayout from AppBar in onDetach()
#Override
public void onDetach() {
appBarLayout.removeView(tabLayout);
super.onDetach();
}
To fix my problem I ended up putting the Toolbar, TabLayout, and ViewPager all in my MainActivity.
main_activity.xml:
<android.support.v4.widget.DrawerLayout 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/drawerLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.CoordinatorLayout
android:id="#+id/rootLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar" />
<android.support.design.widget.TabLayout
android:id="#+id/tabLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabMode="fixed"
app:tabGravity="fill"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"/>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#android:color/white" />
</android.support.design.widget.AppBarLayout>
<RelativeLayout
android:id="#+id/flContent"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
</android.support.design.widget.CoordinatorLayout>
<android.support.design.widget.NavigationView
android:id="#+id/navigation"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="#layout/nav_header"
app:itemIconTint="#333"
app:itemTextColor="#333"
app:menu="#menu/navigation_drawer_items" />
</android.support.v4.widget.DrawerLayout>
Then, in all of my fragments, I set the visibility for the TabLayout and the ViewPager programmatically in onCreateView:
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
TabLayout tabLayout = (TabLayout) getActivity().findViewById(R.id.tabLayout);
tabLayout.setVisibility(View.GONE);
ViewPager mViewPager = (ViewPager) getActivity().findViewById(R.id.viewpager);
mViewPager.setVisibility(View.GONE);
return inflater.inflate(R.layout.fragment_layout, container, false);
}
Of course, in the fragment with tabs, you would want to set the visibility to View.VISIBLE instead of View.GONE.
The Artem_lens approach worked for me with some modifications.
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
...
mTabLayout = (TabLayout) inflater.inflate(
R.layout.partial_tab_layout,
container,
false);
mAppBarLayout = (AppBarLayout) getActivity().findViewById(R.id.app_bar);
mAppBarLayout.addView(mTabLayout,
new LinearLayoutCompat.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT));
...
}
And removing the view at onDestroyView()
#Override
public void onDestroyView() {
mAppBarLayout.removeView(mTabLayout);
super.onDestroyView();
}
The solution is simple in the XML. Just add the following code to your AppBarLayout: app:elevation="0dp". So the AppBarLayout should look like this:
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:elevation="0dp"
android:theme="#style/AppTheme.AppBarOverlay">
