I have a viewpager inside in a activity. This activity launch three fragements (not tabbed), as created three different class extends fragment. It is working fine with horizontal scrolling in between fragment.
Now I want to use collapsingToolbar with separate image display in fragment.
Activity - having viewpager, Fragment1 XML having collapsingToolbar, Fragement1 also have 'content_launch.xml' Fragement1 class - toolbar added but while fetching (CollapsingToolbar object it is returning null.
Activity XML as below :
<LinearLayout 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:id="#+id/launchpager"
android:layout_width="match_parent"
android:layout_height="0px"
android:layout_weight="1" app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
</LinearLayout>
Activity Class to launch viewpager
ViewPager viewPager = (ViewPager) findViewById(R.id.launchpager);
viewPager.setAdapter(new LaunchAdapter(getSupportFragmentManager
(),getApplicationContext()));

((AppCompatActivity) getActivity()).setSupportActionBar(quoteToolbar);
final CollapsingToolbarLayout collapsingToolbar = (CollapsingToolbarLayout) getActivity().findViewById(R.id.quote_collapsing_toolbar);
}
collapsingToolbar object returned as null, not able to find any suggestions, can someone suggest possible way to get object..
First thing: you should not use onCreate to initialize view elements in fragment, you should use onCreateView instead. Second one you don't use getActivity() context.
So instead of this code:
public void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Toolbar quoteToolbar = (Toolbar) getActivity().findViewById(R.id.quote_toolbar);
((AppCompatActivity) getActivity()).setSupportActionBar(quoteToolbar);
final CollapsingToolbarLayout collapsingToolbar = (CollapsingToolbarLayout) getActivity().findViewById(R.id.quote_collapsing_toolbar);
}
use this:
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container,
#Nullable Bundle savedInstanceState) {
// inflate your layout.
View view = inflater.inflate(R.layout.yourlayout, container, false);
Toolbar quoteToolbar = (Toolbar) view.findViewById(R.id.quote_toolbar);
((AppCompatActivity) view).setSupportActionBar(quoteToolbar);
final CollapsingToolbarLayout collapsingToolbar = (CollapsingToolbarLayout) view.findViewById(R.id.quote_collapsing_toolbar);
return view
}
Best regards and happy new year! :)

CollapsingToolbarLayout title have a strange top margin but only when it is collapsed and only when inside a fragment.
Prior to the 25.0.0 version of Design Support Library everything worked fine.

Any ideas?
I have the same issue right now, but it's because I'm hosting it inside a FrameLayout and LinearLayout and they aren't calling their children's "OnApplyWindowInsets" methods.
Even when fixing that I still get the issue.
But for you, try to only have android:fitsSystemWindows="true" on your CoordinatorLayout, not the rest. I think what you're seeing is a double insets because you have it on almost all your controls.
i am working on a android project where i have to implement collapsing toolbar with tabs . Tabs should contain a normal Relative layout which has 4 textview.
I am successfully able to implement the collapsing toolbar but the problem is when ever i try to scroll upwards holding the tabs i have implemented collapse toolbar is not working. On the same tabs if i use a list view or Grid layout its working fine when i scroll. If i try to use Normal layout's such as Linear or Relative layout i am not able to scroll. is there any way i can fix this without list or grid layout?
below is my code for xml:

Try this
Step 1. main_activity.xml

Step:2 Create fragments activity
- FragmentActivity1
fragment1.xml

<!-- TODO: Update blank fragment layout -->
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="#string/hello_blank_fragment1" />
FragmentActivity.java
public class FragmentActivity1 extends Fragment {
public FragmentActivity1()
{
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_fragment_activity1, container, false);
}
}
Step:3 take two other Fragment 2,3 and write code as above
Step:4 MainActivity.java
public class MainActivity extends AppCompatActivity {
private ViewPager pager;
private TabLayout tabLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolBar_hotel_detail);
setSupportActionBar(toolbar);
ViewCompat.setTransitionName(findViewById(R.id.app_bar_layout), "Extra Image");
CollapsingToolbarLayout collapsingToolbarLayout = (CollapsingToolbarLayout)
findViewById(R.id.collapsingToolBar_hotel_details); collapsingToolbarLayout.setContentScrimColor(ContextCompat.getColor(getApplicationContext(), R.color.colorPrimary));
collapsingToolbarLayout.setTitle("Collaps");
pager = (ViewPager) findViewById(R.id.viewPager);
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
adapter.addFragment(new FragmentActivity1());
adapter.addFragment(new FragmentActivity2());
adapter.addFragment(new FragmentActivity3());
pager.setAdapter(adapter);
tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(pager);
tabLayout.getTabAt(0).setText("Tab1");
tabLayout.getTabAt(1).setText("Tab2");
tabLayout.getTabAt(2).setText("Tab3");
}
class ViewPagerAdapter extends FragmentPagerAdapter {
private final List<Fragment> mFragmentList = 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) {
mFragmentList.add(fragment);
}
}
}
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.
Shortened layout:
<android.support.design.widget.CoordinatorLayout
<android.support.design.widget.AppBarLayout
<android.support.design.widget.CollapsingToolbarLayout
<ImageView ..
<android.support.v7.widget.Toolbar ..
</android.support.design.widget.CollapsingToolbarLayout>
<android.support.design.widget.TabLayout
android:id="#+id/main.tabs"
android:layout_width="fill_parent"
android:layout_height="?attr/actionBarSize"
app:tabSelectedTextColor="?android:attr/textColorPrimaryInverse"
app:tabIndicatorColor="?android:attr/textColorPrimaryInverse"
app:tabIndicatorHeight="4dp" />
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/dashboard.viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
/>
Activity:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_dashboard);
CollapsingToolbarLayout collapsingToolbarLayout = (CollapsingToolbarLayout) findViewById(R.id.main_collapsing);
collapsingToolbarLayout.setTitle(getString(R.string.app_name));
ViewPager viewPager = (ViewPager) findViewById(R.id.dashboard_viewpager);
viewPager.setAdapter(new TabsAdapter(getSupportFragmentManager()));
TabLayout tabLayout = (TabLayout) findViewById(R.id.main_tabs);
tabLayout.setupWithViewPager(viewPager);
}
class TabsAdapter extends FragmentPagerAdapter {
public TabsAdapter(FragmentManager fm) {
super(fm);
}
public int getCount() {
return 1;
}
public Fragment getItem(int i) {
switch(i) {
case 0: return DashboardHomeFragment.newInstance();
}
return null;
}
public CharSequence getPageTitle(int position) {
return "Home";
}
}
Fragment:
public class DashboardHomeFragment extends Fragment implements View.OnClickListener {
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_dashboard_home, container, false);
}
public void onActivityCreated(#Nullable Bundle state) {
log.debug("onActivityCreated()");
super.onActivityCreated(state);
}
and its layout:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Hry"
android:textAppearance="#style/TextAppearance.Header"
android:paddingRight="8dp"
android:paddingLeft="8dp"
style="#style/TextComponent.ItemRow"/>
<TextView
android:id="#+id/main.button.puzzle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Najdi výsledek"
android:textAppearance="#style/TextAppearance.Item"
android:drawableRight="#drawable/ic_arrow_forward_24dp"
style="#style/TextComponent.ItemRow.Selectable"/>
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.
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar_layout"
android:layout_width="match_parent"
android:layout_height="256dp"
android:fitsSystemWindows="true"

<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="202dp"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
app:contentScrim="#color/your_color"
android:fitsSystemWindows="true">
<--Your views-->
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:gravity="top"
app:titleMarginTop="13dp"
android:minHeight="?attr/actionBarSize"
app:popupTheme="#style/AppTheme.PopupOverlay"
app:layout_collapseMode="pin"
/>
</android.support.design.widget.CollapsingToolbarLayout>
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:layout_gravity="bottom"
android:background="#color/your_color"
app:tabSelectedTextColor="#color/your_color"
app:tabTextColor="#color/your_color"
app:tabIndicatorColor="#color/your_color"
app:tabMode="fixed"
app:tabGravity="fill"
/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
/>
</android.support.design.widget.CoordinatorLayout>
I am trying to achieve the following affect (also see image below):
the app opens with a view (map) partially visible and the RecyclerView at a default anchor point (center image)
user scrolls the RecyclerView up, the map collapses and the list continues scrolling (right image)
user scrolls the RecyclerView down, the map expands to a maximum point (note the list should not slide completely off screen but to some anchored point) (left image)
To create this we need 1 Activity and 3 Fragments.
The Activity will host a TabLayout and a ViewPager like so:
<LinearLayout 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:orientation="vertical">
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar" />
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
Since we only need to do the sliding behavior for the 1st Fragment the first Fragment gets an XML layout like so:
<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/appBarLayout"
android:layout_width="match_parent"
android:layout_height="400dp"
android:orientation="vertical"
android:fitsSystemWindows="true">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsingToolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<com.google.android.gms.maps.MapView
android:id="#+id/mapView"
app:layout_collapseMode="parallax"
android:layout_height="400dp"
android:layout_width="match_parent" />
</android.support.design.widget.CollapsingToolbarLayout>
</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"/>
</android.support.design.widget.CoordinatorLayout>
You can make the other Fragments however you like I just created fake data and a simple RecyclerView in the other Fragments.
Then call these views in your Activity and Fragment like so:
Activity
public class MainActivity extends AppCompatActivity {
private TabLayout mTabLayout;
private ViewPager mViewPager;
private SampleViewPagerAdapter mViewPagerAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.another_activity);
mTabLayout = (TabLayout) findViewById(R.id.sliding_tabs);
mViewPager = (ViewPager) findViewById(R.id.viewpager);
mViewPagerAdapter = new SampleViewPagerAdapter(getSupportFragmentManager());
mViewPager.setAdapter(mViewPagerAdapter);
mTabLayout.setupWithViewPager(mViewPager);
}
}
ViewPager Adapter
public class SampleViewPagerAdapter extends FragmentPagerAdapter {
public SampleViewPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return new MapFragment();
case 1:
return new ScrollFragment();
case 2:
return new ScrollFragment();
default:
return new ScrollFragment();
}
}
#Override
public int getCount() {
return 3;
}
#Override
public CharSequence getPageTitle(int position) {
String[] tabNames = {"Stops", "Planner", "Alerts"};
return tabNames[position];
}
}
Map Fragment with Sliding RecyclerView
public class MapFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View root = inflater.inflate(R.layout.activity_main, null);
initCollapsingToolbar(root);
// Initialize map
initFragment();
return root;
}
private void initCollapsingToolbar(View root) {
CollapsingToolbarLayout collapsingToolbarLayout =
(CollapsingToolbarLayout) root.findViewById(R.id.collapsingToolbar);
collapsingToolbarLayout.setContentScrimColor(getResources().getColor(R.color.cyan_500));
}
private void initFragment() {
FakeDataFragment fragment = new FakeDataFragment();
getChildFragmentManager().beginTransaction()
.replace(R.id.content, scrollFragment)
.commit();
}
}
You should get something like this then:
Setting the position:
You can programmatically collapse the toolbar (CollapsingToolbarLayout) using the following code:
public void collapseToolbar(){
CoordinatorLayout.LayoutParams params = (CoordinatorLayout.LayoutParams) mFrameLayout.getLayoutParams();
AppBarLayout.ScrollingViewBehavior behavior = (AppBarLayout.ScrollingViewBehavior) params.getBehavior();
if (behavior != null) {
behavior.onNestedFling(rootLayout, appbarLayout, null, 0, 10000, true);
}
}
This means when the User first sees the map the map is partially collapsed to your Default State.

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:layout_height="match_parent"

</android.support.design.widget.AppBarLayout>

</android.support.design.widget.CoordinatorLayout>
<android.support.design.widget.NavigationView
android:id="#+id/navigation"
android:layout_width="wrap_content"
android:layout_height="match_parent"

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:orientation="vertical"

<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">
