Floating button between action bar and Frame Layout

I want something like this:
I have the following now:
With the following XML:
<?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_height="130dp"
android:layout_width="match_parent">
<android.support.design.widget.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:toolbarId="#+id/toolbar"
app:layout_scrollFlags="scroll|enterAlways|enterAlwaysCollapsed"
app:contentScrim="?attr/colorPrimary">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_height="?attr/actionBarSize"
android:layout_width="match_parent">
</android.support.v7.widget.Toolbar>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="android.support.design.widget.AppBarLayout$ScrollingViewBehavior">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/book_detail">
</FrameLayout>
</android.support.v4.widget.NestedScrollView>
<android.support.design.widget.FloatingActionButton
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:src="#android:drawable/ic_input_add"
android:layout_margin="16dp"
android:clickable="true"
android:focusable="true"
app:layout_anchor="#id/appbar"
app:layout_anchorGravity="bottom|end"/>
</android.support.design.widget.CoordinatorLayout>
But I have some problems:
The Title is on top instead of bottom
There's something like a separator on top
I'm using a coordinator now, but I don't need a collapsing toolbar, so I think that there must be another solution maybe. How can I solve this?

Let's first start by making the toolbar taller. I think what you're looking for is CollapingToolbarLayout
To use the CollapsingToolbarLayout you have to change your ConstraintLayout to CoordinatorLayout.
Then you have to create an AppBarLayout to hold the CollapsingToolbarLayout and the Toolbar.
Then to make the floating button in that place you have to anchor it to the AppBarLayout created earlier like below:
<android.support.design.widget.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="top|end"
android:layout_margin="16dp"
app:layout_anchor="#id/app_bar"
app:layout_anchorGravity="bottom|end"
android:clickable="true"
android:src="#drawable/message"
android:focusable="true"
app:elevation="30dp"/>
That way it will be anchored to the AppBarLayout so it will go up and down as the AppBarLayout goes up or down.
EDIT #1 :
To remove the title from the top and remove the separator you have to set your activity's theme to NoActionBar. In your AndroidManifest.xml file go to your activity and change its code to the following:
<activity
android:name="YOUR_ACTIVITY_PATH.BookDetailActivity"
android:theme="#style/AppTheme.NoActionBar" />
This way the activity will be declared without an action bar which means no separator and no title.
Then to add the title to the bottom you just have to set the title of the CollapsingToolbarLayout to the text you want.
You can set it in the xml with app:title="YOUR_TITLE" attribute or you can set it programmatically by calling the function setTitle("YOUR_TITLE") for your CollapsingToolbarLayout variable .
Here is what the full code could look like:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout

app:layout_anchorGravity="bottom|end"
android:clickable="true"
android:src="#drawable/message"
android:focusable="true"
app:elevation="30dp"/>
</android.support.design.widget.CoordinatorLayout>
EDIT 2:
In your activity set your action bar by this :
setSupportActionBar(YOUR_TOOLBAR_VARIABLE) then you can use getSupportActionBar().setDisplayHomeAsUpEnabled(true)
Note that the toolbar should be the id of this one:
android.support.v7.widget.Toolbar so in our case the toolbar with the id toolbar

Use this layout
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar_layout"
android:layout_width="match_parent"
android:layout_height="192dp">
<android.support.design.widget.CollapsingToolbarLayout
android:elevation="4dp"
android:id="#+id/collapsing_toolbar"
android:background="#color/primary"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
<android.support.design.widget.FloatingActionButton
style="#style/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:clickable="true"
app:layout_anchor="#id/app_bar_layout"
app:layout_anchorGravity="bottom|right|end" />
The use this class for action of FAB
public class FlexibleSpaceExampleActivity extends AppCompatActivity
implements AppBarLayout.OnOffsetChangedListener {
private static final int PERCENTAGE_TO_SHOW_IMAGE = 20;
private View mFab;
private int mMaxScrollSize;
private boolean mIsImageHidden;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_flexible_space);
mFab = findViewById(R.id.flexible_example_fab);
Toolbar toolbar = (Toolbar) findViewById(R.id.flexible_example_toolbar);
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override public void onClick(View v) {
onBackPressed();
}
});
AppBarLayout appbar = (AppBarLayout) findViewById(R.id.flexible_example_appbar);
appbar.addOnOffsetChangedListener(this);
}
#Override
public void onOffsetChanged(AppBarLayout appBarLayout, int i) {
if (mMaxScrollSize == 0)
mMaxScrollSize = appBarLayout.getTotalScrollRange();
int currentScrollPercentage = (Math.abs(i)) * 100
/ mMaxScrollSize;
if (currentScrollPercentage >= PERCENTAGE_TO_SHOW_IMAGE) {
if (!mIsImageHidden) {
mIsImageHidden = true;
ViewCompat.animate(mFab).scaleY(0).scaleX(0).start();
/**
* Realize your any behavior for FAB here!
**/
}
}
if (currentScrollPercentage < PERCENTAGE_TO_SHOW_IMAGE) {
if (mIsImageHidden) {
mIsImageHidden = false;
ViewCompat.animate(mFab).scaleY(1).scaleX(1).start();
/**
* Realize your any behavior for FAB here!
**/
}
}
}
public static void start(Context c) {
c.startActivity(new Intent(c, FlexibleSpaceExampleActivity.class));
}
}
There are some Github Implementation to develope this view and many other
Collapsing Toolbar with Fab

first item on recyclerview stacked up to tab layout

i already check the xml file, but everything is okay (for me), but the view still stacked up. and i also get an error message like this
PlayingFragment: onResponse: hasil
pemanggilanretrofit2.ExecutorCallAdapterFactory$ExecutorCallbackCall#1c95dee5
and here's what inside on onResponse on my PlayingFramgment class
private void bacaData(){
progressBar.setVisibility(View.VISIBLE);
final RecyclerView rvCategory = getActivity().findViewById(R.id.playing_daftar);
rvCategory.setLayoutManager(new LinearLayoutManager(getActivity()));
ApiInterface apiInterface = ApiClient.getRetrofit(getContext()).create(ApiInterface.class);
Call<MovieResponse> call = apiInterface.getNowPlaying();
call.enqueue(new Callback<MovieResponse>() {
#Override
public void onResponse(Call<MovieResponse> call, Response<MovieResponse> response) {
MovieResponse data = response.body();
if (data.getResults().size() == 0){
Toast.makeText(getContext(), "Maaf data yang anda cari tidak ditemukan",
Toast.LENGTH_SHORT).show();
progressBar.setVisibility(View.GONE);
} else {
rvCategory.setAdapter(new MoviesAdapter(data.getResults(), R.layout.list_movie_row, getContext()));
Log.d(TAG, "onResponse: hasil pemanggil" + call);
progressBar.setVisibility(View.GONE);
}
}

You should use below property so your viewPager below your upper tab. I think your viewPager have height and width both are match parent.

Since you are using RelativeLayout as root component you have to give margin top to RecyclerView:
android:layout_marginTop="104dp"
EDIT:
if you were using coordinatorLayout as Root layout, the story would be different.
EDIT
Following issues are obvious in your codes:
1- AppBarLayout in Fragment home is extra since you have already an Appbar in activitie's home layout.
2- According to android official document use CoordinatorLayout instead of RelativeLayout. By using RelativeLayout you will loose some functionality and layout management of AppBarLayout
3- Since you have just included content_main inside app_bar_main, no needs to use tools:context=".MainActivity" and tools:showIn="#layout/app_bar_main"
4- Replace RelativeLayout inside content_main by merge tag
After above changes you have just removed extra layouts which may have side effects on margins and padings, then apply attribute below to your view pager. I hope these changes will be effective and no other hidden items are alive in your code:
android:layout_marginTop="104dp"

change you Relativelayout to android.support.design.widget.CoordinatorLayout and add app:layout_behavior="#string/appbar_scrolling_view_behavior" to android.support.v7.widget.RecyclerView

Use this for app_mar_main:
<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"
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<android.support.design.widget.AppBarLayout
android:id="#+id/appbarlayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:popupTheme="#style/AppTheme.PopupOverlay" />
<android.support.design.widget.TabLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/colorPrimaryDark"
app:tabTextColor="#color/colorAccent"
app:tabSelectedTextColor="#color/colorAccent"
android:id="#+id/tabs">
<android.support.design.widget.TabItem
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/tab_np"
android:text="#string/now_playing"
android:textColor="#color/colorAccent"/>
<android.support.design.widget.TabItem
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/up_coming"
android:id="#+id/tab_up"/>
</android.support.design.widget.TabLayout>
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_main"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:layout_below="#+id/appbarlayout"
android:layout_marginTop="1dp"/>
</RelativeLayout>

Try this way..
make viewpager xml code..
<?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:clickable="true"
android:fitsSystemWindows="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/tab_bg_color"
android:orientation="vertical">
<android.support.design.widget.TabLayout
android:id="#+id/tlConversation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabGravity="fill"
app:tabIndicatorColor="#color/tab_color"
app:tabMinWidth="0dp"
app:tabMode="fixed"
app:tabTextAppearance="#style/Tab_Style"
app:tabSelectedTextColor="#color/tab_color"
app:tabTextColor="#color/tab_text_color">
</android.support.design.widget.TabLayout>
<android.support.v4.view.ViewPager
android:id="#+id/vpPager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/white">
</android.support.v4.view.ViewPager>
</LinearLayout>
</android.support.design.widget.CoordinatorLayout>
after that fragement xml code for recyclerview ..
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tool="http://schemas.android.com/tools">
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/rvData"
tool:listitem="#layout/item_row_layout"
></android.support.v7.widget.RecyclerView>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/tvEmpty"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
tool:text="No data found"
android:text="#string/no_found"
android:visibility="gone"
/>
</android.support.constraint.ConstraintLayout>
after that setup view pager like this way make viewpager adapter..
private void setupViewPager(ViewPager viewPager) {
viewPagerAdapter = new ViewPagerAdapter(getActivity().getSupportFragmentManager(),conversationId);
viewPager.setAdapter(viewPagerAdapter);
viewPager.setOffscreenPageLimit(1);
viewPager.setCurrentItem(currentItem);
}
And
public class ViewPagerAdapter extends FragmentPagerAdapter {
private final Context context;
public ViewPagerAdapter(FragmentManager fragmentManager, Context context) {
super(fragmentManager);
this.context = context;
}
#Override
public Fragment getItem(int position) {
if(position == 0) return new ActiveConversationFragment();
if(position == 1) return new InvitedConversationFragment();
if(position == 2) return new RecentConversationFragment();
throw new IllegalStateException("Unexpected position " + position);
}
#Override
public int getCount() {
return 3;
}
#Override
public CharSequence getPageTitle(int position) {
if(position == 0) return context.getString(R.string.tab_active_conversation_title);
if(position == 1) return getString(R.string.tab_invited_conversation_title);
if(position == 2) return getString(R.string.tab_recent_conversation_title);
throw new IllegalStateException("Unexpected position " + position);
}
}
after that call above method like this way set into tablayout..
setupViewPager(viewPager);
tabLayout.setupWithViewPager(viewPager);

Add Toolbar/Actionbar to PreferenceActivity

I am trying to add a toolbar to my PreferenceActivity.
I have looked around here and a number of places and nothing seems to work.
I am using headers for my top-level.
I tried to then use my own layout in onCreate including the required toolbar and making sure it has a view by the name of "#android:id/list".
<?xml version="1.0" encoding="utf-8"?>
<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:layout_height="match_parent"
android:orientation="vertical">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:title="#string/app_name"
app:navigationIcon="#drawable/back"
app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<ListView android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
</LinearLayout>
This worked okay for the top level but then the next level failed looking for a view name "android:id/prefs".
java.lang.IllegalArgumentException: No view found for id 0x102040a (android:id/prefs) for fragment PreferencesFragmentButtonInteraction{7a6584a #0 id=0x102040a}
The only code in the onCreate of the fragment is the AddPreferencesFromResource.
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Load the preferences from an XML resource
addPreferencesFromResource(R.xml.preferences_button_interaction);
}
I have tried to use a theme and set in in the manifest but to no avail.

You can use PreferenceFragmentCompat wrapped in a normal AppCompatActivity. Then you can easily attach an appbar to your activity using
setContentView(R.layout.activity_setting);
and preferences can be set to the fragment using
setPreferencesFromResource(R.xml.preferences_button_interaction, rootKey);
If you wish to add toolbar to your current activity, you can try this method
private void setupActionBar() {
ViewGroup rootView = (ViewGroup)findViewById(R.id.action_bar_root); //id from appcompat
if (rootView != null) {
View view = getLayoutInflater().inflate(R.layout.app_bar_layout, rootView, false);
rootView.addView(view, 0);
Toolbar toolbar = (Toolbar)findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
}
ActionBar actionBar = getSupportActionBar();
if (actionBar != null) {
// Show the Up button in the action bar.
actionBar.setDisplayHomeAsUpEnabled(true);
}
}
app_bar_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.AppBarLayout

android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"

How to include a TabLayout in a Toolbar in Fragments

i was trying to implement a tabbed view using ViewPager and TabLayout in a fragment,
i managed to do that but the tabs are not included in the toolbar which is located at the top of the screen.
i have included the screenshot of what i have got.
can someone please tell me how i can move the tabs to the toolbar and also the tabs doesnt change
when they are touched they only change when swipped left or right.
i have tried adding the android.support.design.widget.TabLayout in android.support.design.widget.AppBarLayout in the tabslayout.xml file
it add a blue background on it and the touches work but still its not included in the toolbar.
Here are the codes.
1.Tabs.java
import android.os.Bundle;
import android.support.design.widget.TabLayout;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import java.util.ArrayList;
import java.util.List;
public class Tabs extends Fragment {
public Tabs() {
// Required empty public constructor
}
private TabLayout tabLayout;
private ViewPager viewPager;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View mekeleLayout = inflater.inflate(R.layout.tabs_layout,container,false);
viewPager = (ViewPager) mekeleLayout.findViewById(R.id.viewpager);
setupViewPager(viewPager);
tabLayout = (TabLayout) mekeleLayout.findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);
return mekeleLayout;
}
private void setupViewPager(ViewPager viewPager) {
ViewPagerAdapter adapter = new ViewPagerAdapter(getFragmentManager());
adapter.addFrag(new OneFragment(), "RESTAURANTS");
adapter.addFrag(new TwoFragment(), "CAFES");
adapter.addFrag(new ThreeFragment(), "HOTELS");
viewPager.setAdapter(adapter);
}
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 addFrag(Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
#Override
public CharSequence getPageTitle(int position) {
return mFragmentTitleList.get(position);
}
}
}
2.tabslayout.xml
<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.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabGravity="fill"
/>
<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>
3.activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<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/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">
<include
layout="#layout/app_bar_main"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="#layout/nav_header_main"
app:menu="#menu/activity_main_drawer" />
</android.support.v4.widget.DrawerLayout>
4.app_bar_main.xml
<?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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.example.surafel.information.MainActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<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/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_main" />
</android.support.design.widget.CoordinatorLayout>

This is working for me.
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout

app:tabIndicatorColor="#color/colorAccent"
app:tabMaxWidth="0dp"
app:tabGravity="fill"
app:tabMode="scrollable"
android:background="#color/colorPrimary" />
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/tabanim_viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>

You should use a theme for the activity which does not have an Action Bar.

Try below one
<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"
android:layout_width="match_parent"
android:layout_height="fill_parent"
>
<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">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="#+id/app_bar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:minHeight="?android:attr/actionBarSize"
app:layout_scrollFlags="scroll|enterAlways"
app:theme="#style/appBar">
</android.support.v7.widget.Toolbar>
<android.support.design.widget.TabLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_scrollFlags="scroll|enterAlways"
app:tabBackground="#color/app_bar_color"
app:tabGravity="center"
app:tabMode="scrollable" />
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/viewPagerTheme"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</LinearLayout>
</android.support.design.widget.CoordinatorLayout>
add appbar theme in your styles.xml
<style name="appBar" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="android:textColorPrimary">#android:color/black</item>
<item name="android:textColorSecondary">#android:color/white</item>
</style>
