Menu is not showing in custom toolbar in fragments

I have created a custom toolbar for the fragment that I have created and it is supposed to look like this:
The toolbar shown on the left side is from my fragment_purchase_item_list and the right side is for my fragment_purchase_list.
I have tried checking some other posts from here which I followed but it will not show up the menu that I have created.
When I run the code, it will look like this:
The search icon (left), scan and new icon (right) will not show up. Here are my codes:

That is not possible with PagerTabStrip and ToolBar. Since ActionBarTabs have been deprecated, use a TabLayout.

Here is the Code that how you can use TabLayout easily.
Here is the output that you will get.
main_activty.xml or any of your XML file where your want to use these Tabs and Viewpager
<android.support.design.widget.AppBarLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar" android:id="#+id/appBarLayout"

app:layout_constraintTop_toTopOf="parent"
app:layout_constraintStart_toStartOf="parent">

android:layout_width="match_parent"
android:layout_height="wrap_content"

fragment text appearing in toolbar

I'm trying to get a sliding drawer set up. I want the text to appear in the main body of the activity, but instead it's appearing inside of the toolbar, and it only says This is fragment 2, regardless of whether I pulled up the fragment that's supposed to say This is fragment 1 or This is fragment 2.
How can I make it pull up the proper fragment, instead of always fragment 2, and how can I make the toolbar opaque, with text appearing under it instead of in it.

transaction.addToBackStack(null);
transaction.commit();
}
}
}

I solved one part of this issue, though I'm not certain I used best practices. I added padding to the top of main_content in a size of "?attr/actionBarSize"
But it's still only displaying This is Fragment 2, regardless of which fragment I'm trying to select.

If you want the content below the toolbar, you can wrap toolbar and content in one layout as:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:minHeight="?attr/actionBarSize"
android:layout_alignParentTop="true"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
/>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/main_content"
android:background="#8000ff00"
>
</RelativeLayout>
</LinearLayout>
Besides, if you are using Android Studio, creating Navigation Drawer Activity through the wizard is the best way to ensure that everything works properly.

How to display specific icons in dashboard layout?

I am developing an android application in that,I am using dashboard layout that contains icons(showed in image-1).Dashboard layout is common for all the three tabs,Now my dashboard layout is looking below,
Bydefaultly ,when i am login my app the invitation tab will opened as similar to above image.In that image dashboard layout have 3 icons(i.e "dropdown,event,settings")
But i want to change icon on dashboard based on tab click functionality.
for example,
In image-2 ,"Invitation tab" need to show "settings icon" only on dashboard layout except that icon no other icon need to display when i am in "invitation tab".
Similarly in image-3, when i am in "event tab" i need to show "event & settings" icons in dashboardlayout.
In image-4, when i am in "groupchat tab" i need to show "dropdown & settings" icons in dashboard layout.
My menu_dashboard code is below
<menu xmlns:android="http://schemas.android.com/apk/res/android"

How to fix this problem please help me.

Use The ToolBar With Icons in the Activity and when the tab changed Customise your layout
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
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="wrap_content"
android:background="#color/primary"
android:drawingCacheQuality="low"
android:minHeight="#dimen/abc_action_bar_default_height_material"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="right"
android:layout_weight="1"
android:background="#android:color/transparent"
android:gravity="right">
<ImageView
android:id="#+id/notification"
android:layout_width="#dimen/abc_action_button_min_width_material"
android:layout_height="#dimen/abc_action_bar_default_height_material"
android:layout_centerVertical="true"
android:gravity="center"
android:lines="1"
android:padding="5dp"
android:src="#drawable/ic_action_notification"
android:textAppearance="?android:attr/textAppearanceMedium"
/>
<ImageView
android:id="#+id/searchView"
android:layout_width="#dimen/abc_action_button_min_width_material"
android:layout_height="#dimen/abc_action_bar_default_height_material"
android:layout_centerVertical="true"
android:gravity="center"
android:lines="1"
android:padding="5dp"
android:src="#drawable/ic_title_search_default"
android:textAppearance="?android:attr/textAppearanceMedium"
/>
</LinearLayout>
and on your Activity something like this
myTabHost.setOnTabChangedListener(new OnTabChangeListener() {
#Override
public void onTabChanged(String tabId) {
if (TAB_1_TAG.equals(tabId)) {
notification.setVisibility(View.GONE);
searchView.setVisibility(View.VISIBLE);
}
if (TAB_2_TAG.equals(tabId)) {
notification.setVisibility(View.VISIBLE);
searchView.setVisibility(View.GONE);
}
}
});

android browser does not open url when clicked one more times
