in the same activity i add three fragments so that i want that image on each fragment on tollbar
when i debug the code ImageButton btnCart = (ImageButton) toolbar.findViewById(R.id.btn_cart); here it will null for btn_cart
i think it will not get the id of cart button but when i use this code for my main activity it will show cart image on toolbar. but not in this Mobilerecharge activity my btn_cart is located in my Toolbar xml file
so please any one tell me how i add image on toolbar to the activity which contain tab fragments.

replace
ImageButton btnCart = (ImageButton) toolbar.findViewById(R.id.btn_cart);
with
ImageButton btnCart = (ImageButton)findViewById(R.id.btn_cart);
because it is already in same activity
edit
as your xml code there is already a toolbar so you don't need to add another tool bar just copy imagebutton toobar in your xml file as below
<LinearLayout
android:id="#+id/main_layout"

android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"

</LinearLayout>

I assume you saved the Toolbar layout as "toolbar.xml"
Now in your mobilerecharge activity xml layout just include the layout like this
<LinearLayout
android:id="#+id/main_layout"
android:orientation="vertical"
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.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<include
android:id="#+id/toolbar"
layout="#layout/toolbar"/>
<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"/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</LinearLayout>
Now inside your activity class you can refer it like you did.
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
ImageButton btnCart = (ImageButton) toolbar.findViewById(R.id.btn_cart);

TabLayout disappearing behind ViewPager in CollapsingToolBar

Im trying to create an AppBarLayout using the CollapsingToolBar which contains a Toolbar and a TabLayout and im also using the app:behavior_overlapTop attribute on my RelativeLayout which includes a ViewPager. The problem is that when the CollapsingToolBar is expanded my TabLayout disappears behind the ViewPager as the TabLayout is given a layout_gravity = bottom and due to the fact that i have used app:behavior_overlapTop on my RelativeLayout which includes the ViewPager. How can i fix this ? Thanx in advance.

View pager is overlapping the tab fragments vertically

I am using Viewpager to browse through the tabs. But my viewpager is overlapping the top of the fragment due to which the top of all the fagments are not visible. Adding padding on the top does the work but is there any better way to do it rather than giving padding on the next view.

You have used Relative Layout and not defined android:layout_below="#id/appbar_layout" . So I have edited your code. Just copy and paste below code in your xml file. It'll solve your problem.

How to use Custom Toolbar in entire app

I have made Toolbar using coordinate toolbar in my app so that i can hide toolbar while scrolling . I also have ViewPager inside it . So when user scroll only Toolbar hides and tabs stick to the top . But in other activity i just want to display toolbar what is the better way to that ?
I am sharing my coordinator layout below
<?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/AppBarLayout"

android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/orange"
app:layout_scrollFlags="scroll|enterAlways"
app:titleTextColor="#color/white">
</android.support.v7.widget.Toolbar>
<android.support.design.widget.TabLayout
android:id="#+id/MyTabLayout"
style="#style/TabLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/toolbar"
app:tabTextAppearance="#style/AppTabTextAppearance">
</android.support.design.widget.TabLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/MyViewPager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/MyTabLayout"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
></android.support.v4.view.ViewPager>
</android.support.design.widget.CoordinatorLayout>

Create a separate layout for toolbar only.
toolbar.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="70dp"
android:background="#color/white"
app:layout_scrollFlags="scroll|enterAlways"
app:titleTextColor="#color/white">
</android.support.v7.widget.Toolbar>
Then now its in anywhere in your layout.
<?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/AppBarLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<include
layout="#layout/toolbar"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<android.support.design.widget.TabLayout
android:id="#+id/MyTabLayout"
style="#style/TabLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/toolbar"
app:tabTextAppearance="#style/AppTabTextAppearance">
</android.support.design.widget.TabLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/MyViewPager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/MyTabLayout"
app:layout_behavior="#string/appbar_scrolling_view_behavior"></android.support.v4.view.ViewPager>
</android.support.design.widget.CoordinatorLayout>

If you just want to display Toolbar inside other Activities, you can add the Toolbar to any root layout of the respective Activity like LinearLayout or RelativeLayout (which ever suits your app's needs).

Layout for Fragment overlapping Toolbar

Am replacing/placing my Fragments in a FrameLayout inside of a DrawerLayout with this code:
<?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_base"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<FrameLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!--drawer items-->
<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_base"
app:menu="#menu/activity_base_drawer" />
</android.support.v4.widget.DrawerLayout>
app_bar_base.xml contains a Toolbar and a FAB:
<?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=".BaseActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:id="#+id/appBar"
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>
<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>
When I run my app, this is the result:
As you can see, the layout for the fragment overlaps the Toolbar.How can I fix this?
I've tried placing both the Toolbar and FrameLayout inside a LinearLayout like this:
<LinearLayout
android:layout_width="match_parent"
android:orientation="vertical"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<include
layout="#layout/app_bar_base"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
<FrameLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
but then the FrameLayout gets hidden.

Try adding android:layout_marginTop="?attr/actionBarSize" to the FrameLayout you use to put the Fragments in.
<FrameLayout
android:id="#+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="?attr/actionBarSize"/>
Worked for me :)

Please do not forget to add app:layout_behavior="#string/appbar_scrolling_view_behavior" to your content layout
<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:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
<android.support.design.widget.TabLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.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 tried all the answers, none worked for me. Because I was hiding the action bar, it was complicated further.
But I finally added android:paddingTop="?attr/actionBarSize" to the FrameLayout and that worked for me. Hope that helps someone.

Use below code
<LinearLayout
android:layout_width="match_parent"
android:orientation="vertical"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<include
layout="#layout/app_bar_base"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
<FrameLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" />
</LinearLayout>

You can also use RelativeLayout instead of LinearLayout with attribute android:weight. It's good for performance
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<include
layout="#layout/app_bar_base"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<FrameLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#id/app_bar_base"
/>
</RelativeLayout>

Finally I figured out the solution
Suppose you have Two Fragment Class FragmentOne and FragmentTwowhich you are replacing in your main activity and one of them is overlapping the actionbar/toolbar
In your activity_main.xml create a FrameLayout which you will be using to replace as a fragment
activity_main.xml
<?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:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<!--We will use this framelayout to be replace with fragment so that the above toolbar does not get overlap-->
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/fragment_container"></FrameLayout>
</LinearLayout>
Now in your MainActivity.java
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//Set your toolbar in your MainActivity
Toolbar toolbar = (Toolbar)findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FragmentManager fragmentManager=getFragmentManager();
FragmentTransaction transaction=fragmentManager.beginTransaction();
if(yourOwnConditionToReplaceFragment()){
FragmentOne fragmentOne=new FragmentOne();
//Notice the id passed in replace function it will make sure that FrameLayout is replaced so fragment will occupy only that portion of screen that is taken by FrameLayout in activity_main.xml
transaction.replace(R.id.fragment_container,fragmentOne);
}else{
FragmentTwo fragmentTwo=new FragmentTwo();
transaction.replace(R.id.fragment_container,fragmentTwo);
}
transaction.commit();
}
FragmentOne And FragmentTwo are classes that are extended Fragment in it. If still there is problem let me know

I replaced CoordinateLayout with LinearLayout in the app_bar layout, it worked for me but still it's not the right way.

This is very straight forward and easy. Just follow what I tried to say below.
You replace any View by using:
**
getFragmentManager().beginTransaction()
.replace(R.id.blankFragment, new SettingsFragment())
.commit();
**
//Here, blackFragment is id of FrameLayout View. You replace FrameLayout View with Fragment's Layout. Note: It should be FrameLayout or FrameLayout's derivatives Layout.
My whole code is:
1) SettingsActivity.java
**

Android title bar custom view does not stretch

I use api 21 titlebar in my app. I want to stretch my button or Linearlayout on it, but I can't.
my code:
<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"
tools:context="com.example.toolbartest.MainActivity" >
<android.support.v7.widget.Toolbar
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/my_awesome_toolbar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"
android:background="#ff9900">
<Button
android:layout_height="match_parent"
android:layout_width="match_parent"
android:text="GSSGSDGSDG"/>
</android.support.v7.widget.Toolbar>
</LinearLayout>![enter image description here][1]

xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/my_awesome_toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
