I have a frame layout in the activity. I have put an action bar and bottom navigation bar in the activity, but the problem is the frame layout is going behind the bottom navigation bar, and it's also not scrolling. I want the frame layout to always remain above the bottom navigation bar.
I have tried giving the bottom navigation drawer a fixed height of "56dp", and layout_margin Bottom="56dp". It works fine, But I don't think it is a good solution, because in some cases, I want to hide the bottom navigation bar.

I want the frame layout to remain below the toolbar and above the bottom navigation bar.
But what happens, is the frame layout is below the toolbar, but the frame layout is behind the bottom navigation bar.
Try this:
<FrameLayout
android:id="#+id/fragment_container_dashboard"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginBottom="56dp"
android:layout_above="#+id/nav" />
<include android:id="#+id/nav"
layout="#layout/bottom_nav" />
My approach would be to wrap the wrap the bottom navigation Layout you included in a LinearLayout and then wrap the FrameLayout and the new layout containing the bottom navigation bar in a relative layout then position the frame layout above the bottom navigation bar layout such that:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="#+id/fragment_container_dashboard"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginBottom="56dp"
android:layout_above="#id/bnve"/>
<LinearLayout
android:id="#+id/bnve"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<include layout="#layout/bottom_nav" />
</LinearLayout>
</RelativeLayout>
try to place this include tag above Framelayout like
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v4.widget.DrawerLayout
android:id="#+id/myDrawer"
android:layout_width="match_parent"
android:layout_height="match_parent">
<include layout="#layout/bottom_nav" />
<FrameLayout
android:id="#+id/fragment_container_dashboard"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginBottom="56dp" />
sorry for late answer.. Can you try this ?
<include
android:layout_alignParentBottom="true"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
layout="#layout/bottom_nav" />

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"

android:layout_height="match_parent"
app:expandedTitleMarginBottom="28dp"

app:layout_scrollFlags="scroll|snap">

android:layout_height="wrap_content">

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_height="800dp"
android:text="Hello Test" />
</androidx.cardview.widget.CardView>
</androidx.core.widget.NestedScrollView>
</androidx.coordinatorlayout.widget.CoordinatorLayout>
Output:

for your activity_main.xml copy and paste below layout.

That's it, you don't have to create any other layout. Now wherever you want to have this toolbar you can include your app_bar_main.xml in the layout and you will get the toolbar. Then in your activity if you want to access toolbar and button inside toolbar, do like this:
Toolbar toolbar = findViewById(R.id.account_toolbar);
setSupportActionBar(toolbar);
Button btnEdit = toolbar.findViewById(R.id.menu_button);
let me know if you have any questions. I'll try to help you out.
I don't know if what you are trying to do is a good idea.
From a design perspective, you have only a limited space in the toolbar and you should position there only the most relevant actions to the context, all the other actions are going to be hiden in the classic "three dots" menu.
You can check what I mean here https://developer.android.com/training/appbar/actions
https://material.io/components/app-bars-top#anatomy
Even thouth, to achieve what you are trying to do, I'll do it using Constraint Layout instead of Relative Layout, makes your life easier and is up to date ;) https://developer.android.com/training/constraint-layout
First, create title_menu.xml Layout. make sure android:layout_height="wrap_content" and android:gravity="center"
<?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="wrap_content"
android:gravity="center">
<Button
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:text="Button"/>
</LinearLayout>
Second, add the following code on the onCreate method in your Activity.
getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
getSupportActionBar().setCustomView(R.layout.title_menu);
I've created a menu with a width of 150dp. The toolbar does not match the width of the app. so that the area under the navbar icon is unfilled.

Questions
Why is the toolbar not filling the whole area? How can I fix this?
Can I use something other than a fixed 150dp size to set the height of the navbar? (such as a percentage)

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

I have implemented an activity with two slides, the slides content is a fragment with RecyclerView that loads data from my server and creates a GridLayout with images (like in image gallery).
I have added the behavior of scrolling so when you scroll you don't see the toolbar.
My problem is that when the activity starts with the fragment the toolbar is half hidden and when i continue to scroll down and the toolbar is completely hidden the CoordinatorLayout from under is exposed so i get this thing:
as you can see the light green is the CoordinatorLayout and the red is the ViewPager and what i want to achieve is that when you scroll more you will only see the red background and never the green one.
My activity_main.xml
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/backgroundGray"
android:fitsSystemWindows="true">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="56dp"
android:background="#color/appGreen"
app:layout_scrollFlags="scroll|enterAlways">

</android.support.v7.widget.Toolbar>
<LinearLayout
android:layout_width="match_parent"

android:layout_width="match_parent"

</android.support.design.widget.AppBarLayout>
And my fragment.xml

android:clipToPadding="false"
android:columnWidth="102dp"
android:fitsSystemWindows="true"
android:scrollbars="vertical" />
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/pressToRetryPanel"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:visibility="gone">
<TextView
android:id="#+id/textPressToRetry"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:text="#string/press_to_retry"
android:textColor="#color/black"
android:textSize="16sp" />
</RelativeLayout>
<include
android:id="#+id/loadingPanel"
layout="#layout/loading_template"
android:layout_width="match_parent"
android:layout_height="match_parent" />
How can I make the toolbar to hide when I am scrolling but still see the RecyclerView content on my entire screen?
Thanks...
