OneUi styled navigation in android java

I'm beginner in android programming and I want to know how to make an OneUi styled navigation like in this picture.
This is what I made so far. Unfortunately, when I scroll it, it will totally collapse and I cannot get it back.
I used CoordinatorLayout with AppBarLayout and I follow some code from material.io guidelines but it did'nt work as I expected. I want the app bar to be short when scrolled and tall when it is on the top.
Here is my XML Layout Code:
<androidx.coordinatorlayout.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:background="#F0F0F0"
tools:context=".MainActivity">
<com.google.android.material.appbar.AppBarLayout
android:layout_width="match_parent"
android:layout_height="256dp">
<com.google.android.material.appbar.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:expandedTitleMarginStart="72dp"
app:expandedTitleMarginBottom="28dp"
app:layout_scrollFlags="scroll|snap">
<com.google.android.material.appbar.MaterialToolbar
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_collapseMode="pin"
app:contentInsetStart="0dp">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="This is a text"
android:textSize="50dp"
/>
</RelativeLayout>
</com.google.android.material.appbar.MaterialToolbar>
</com.google.android.material.appbar.CollapsingToolbarLayout>
</com.google.android.material.appbar.AppBarLayout>
<androidx.cardview.widget.CardView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clipToPadding="false">
</androidx.cardview.widget.CardView>
</androidx.coordinatorlayout.widget.CoordinatorLayout>

For your use case. There are few things you need to change.
Put the content below AppBarLayout in NestedScrollView to have scrolling layout_behavior.
Put some content to mimic scrolling effect. Like textview with huge height for example.
Put the content you want to collapse into one CollapsingToolbarLayout basically things to show when it's tall or not collapsed.
Put your MaterialToolbar as a direct child of AppBarLayout
Example code:
<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.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:background="#F0F0F0"
tools:context=".MainActivity">
<com.google.android.material.appbar.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<com.google.android.material.appbar.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:expandedTitleMarginBottom="28dp"
app:expandedTitleMarginStart="72dp"
app:layout_scrollFlags="scroll|snap">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="This is collapsing content"
android:textSize="32sp" />
</RelativeLayout>
</com.google.android.material.appbar.CollapsingToolbarLayout>
<com.google.android.material.appbar.MaterialToolbar
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:contentInsetStart="0dp"
app:layout_collapseMode="pin"
app:title="This is MaterialToolbar" />
</com.google.android.material.appbar.AppBarLayout>
<androidx.core.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="com.google.android.material.appbar.AppBarLayout$ScrollingViewBehavior">
<androidx.cardview.widget.CardView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clipToPadding="false">
<TextView
android:layout_width="match_parent"
android:layout_height="800dp"
android:text="Hello Test" />
</androidx.cardview.widget.CardView>
</androidx.core.widget.NestedScrollView>
</androidx.coordinatorlayout.widget.CoordinatorLayout>
Output:
Not collapsed:
Collapsed:

Hiding Toolbar in tabbed activity with fragment with ScrollView in its ViewPager

I want to hide toolBar when scroll View in fragment of ViewPager is scrolled
but when i scroll only scrollView's part is being scrolled (with toolbar in its place).
consider, when I scroll on tablayout (header part, id- tabs) it hides the toolbar
<androidx.coordinatorlayout.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"
tools:context=".MainActivity">
<com.google.android.material.appbar.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:elevation="5dp"
app:layout_scrollFlags="scroll|enterAlways|snap" />
<com.google.android.material.tabs.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
app:tabIndicatorColor="#android:color/white" />
</com.google.android.material.appbar.AppBarLayout>
<androidx.viewpager.widget.ViewPager
android:id="#+id/view_pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</androidx.coordinatorlayout.widget.CoordinatorLayout>
and in My java file is
Toolbar toolbar = findViewById(R.id.toolbar);
toolbar.setTitle("304 Pramukh");
and my fragments Xml file is
<FrameLayout 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"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context=".Fragments.CommunityFragment">
<!-- TODO: Update blank fragment layout -->
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/rv_family"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
</ScrollView>
</FrameLayout>```

This needed only one minor change,
Just replaced scroll View with Nested scroll view ...

Negative margin Layout to overlay parent layout

I have an activity that has a toolbar and a framelayout where I inject fragments.
This is the layout for that activity:
<android.support.v4.widget.DrawerLayout
android:id="#+id/drwDrawerRoot"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/background_main_selector"
android:theme="#style/AppTheme">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<include
android:id="#+id/viewMainToolbar"
layout="#layout/view_toolbar" />
</LinearLayout>
<FrameLayout
android:id="#+id/frmDrawerContainer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="#dimen/toolbar_height"
android:clipChildren="false"
android:clipToPadding="false"
android:orientation="vertical" />
<include
android:id="#+id/viewDrawer"
layout="#layout/view_drawer"
bind:name="#{name}"/>
<include
android:id="#+id/viewUserDrawer"
layout="#layout/view_user_drawer"
bind:name="#{name}"/>
</android.support.v4.widget.DrawerLayout>
I have the framelayout with a margin so that the contents from the fragments do not overlay the toolbar, but I set clipChildren and clipToPadding to false as per some other posts I have seen here.
On some fragments however I have a loading view, which I would like to occupy all the screen.
This is a sample fragment:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="#+id/layout_main"
style="#style/Layout.FullScreen"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/layout_footer"
android:orientation="vertical">
<TextView
android:id="#+id/textView7"
style="#style/Text.Header"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/login_header" />
<EditText
android:id="#+id/edtMessage"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:elevation="1dp"
android:ems="10"
android:inputType="textMultiLine" />
<Button
android:id="#+id/btnSend"
style="#style/Button.Primary"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/support_button" />
</LinearLayout>
<LinearLayout
android:id="#+id/layout_footer"
style="#style/Layout.FullScreen.Footer"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:orientation="vertical">
<TextView
android:id="#+id/footerInfo"
style="#style/Text.White.Small.Centered"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/footer_info" />
</LinearLayout>
<include
layout="#layout/view_loading"
android:visibility="invisible"
bind:loading="#{loading}" />
</RelativeLayout>
Ans this is the included loading view, which I have set with negative margin, hoping it would move up to the top of the screen:
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="-40dp"
android:background="#color/colorLoadingBackground"
android:clickable="true"
android:visibility="#{loading ? View.VISIBLE : View.GONE}">
</FrameLayout>
Am I missing something here?
Is this doable or do I need to change how I am doing this?
Clarification:
The first / root layout includes a toolbar and the second layout is included within the frame layout of the first. this means that the content of the second layout starts below the toolbar. However, I would like the third layout (a loading screen that is included in the second layout) to have a negative margin so that it overlays the full screen, not just starting below the toolbar.

You need to use CoordinatorLayout then you wont need negative margins. here are the sample layout u can customise according to your need
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawer_layout"
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"
tools:context=".MainActivity">
<android.support.design.widget.CoordinatorLayout
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/AppTheme.AppBarOverlay"
app:layout_behavior= "#string/appbar_scrolling_view_behavior">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:popupTheme="#style/AppTheme.PopupOverlay"
app:title="My App" />
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
<!--include a full screen loading layout here and hide/show according to your need-->
<include layout="#layout/loading_layout/>
</android.support.design.widget.CoordinatorLayout>
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="#layout/nav_header"/>
</android.support.design.widget.NavigationView>
</android.support.v4.widget.DrawerLayout>

How to create an extended toolbar in Android with an EditText at the bottom

I am trying to create a toolbar in Android that is 2x in height of the normal toolbar, and has an EditText in the lower half portion.
Currently, I have the XML code (note the android:layout_height="128dp"):
<RelativeLayout
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.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:title="Messages"
android:titleTextColor="#color/windowBackground"
android:background="#color/buttonBackground"
android:layout_height="128dp"
android:layout_width="match_parent"
android:minHeight="?android:attr/actionBarSize"
android:gravity="bottom" />
<fragment
android:id="#+id/no_activity_fragment"
class="com.ohmd.ohmd.ui.main.MainActivityListFragment"
android:name="com.ohmd.ohmd.ui.main.MainActivityListFragment"
android:layout_below="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="fill_parent"/>
</RelativeLayout>
This is what it looks like (with no EditText yet):
So a few problems that I'm stuck on:
(a) How can I get the "Messages" to align to the top where it does when the height is set to "?android:attr/actionBarSize"?
(b) Aftter moving the title up, how can I add an EditText view in the lower half?
This is what I am hoping to acheive:

Got it with:
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:title="Messages"
android:titleTextColor="#color/windowBackground"
android:background="#color/buttonBackground"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
android:gravity="center" />
<RelativeLayout
android:orientation="vertical"
android:background="#color/buttonBackground"
android:layout_height="?android:attr/actionBarSize"
android:layout_below="#+id/toolbar"
android:id="#+id/card_view"
android:layout_width="match_parent"
android:gravity="center">
<EditText
android:layout_margin="10dp"
android:id="#+id/tvSection"
android:background="#color/buttonBackgroundSelected"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:gravity="center"/>
</RelativeLayout>

Well, you could try changing the toolbar gravity to
android:gravity="top"
If that doesn't work, you could get rid of the "title" and add a TextView to the toolbar like this:
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="128dp"
android:background="#color/buttonBackground"
android:gravity="top"
android:minHeight="?android:attr/actionBarSize"
android:titleTextColor="#color/windowBackground"/>
<TextView
android:id="#+id/button_save"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="top|left"
android:text="Messages"
android:textColor="#color/buttonBackground"/>
</android.support.v7.widget.Toolbar>

Framelayout doesn't show up in main activity

This is my activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<include android:id="#+id/toolbar"
layout="#layout/toolbar"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:layout_below="#+id/toolbar">
<FrameLayout
android:id="#+id/fragment_content"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</FrameLayout>
</LinearLayout>
</LinearLayout>
My toolbar.xml:
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/toolbar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary" />
The fragment I send to fragment_content:
<RelativeLayout 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"
android:background="#ffffff">
<android.support.v4.widget.SwipeRefreshLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/swipe_container"
android:layout_below="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- Listview -->
<ListView
android:id="#+id/lvEvent"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#FFFFFF"
android:divider="#D0D0D0"
android:dividerHeight="0.5dp"
android:showDividers="middle"/>
</android.support.v4.widget.SwipeRefreshLayout>
</RelativeLayout>
Now the toolbar show up, I can do actions with it but there is nothing in my Framelayout? If I delete the include (toolbar) then I can see the content in my Framelayout. Anybody know what I'm doing wrong?

Given that you have set the height of your toolbar to wrap_content, I assume you want a vertical layout, but your top level LinearLayout is set to horizontal. Change the orientation to vertical.
