A ListView overlaps a SearchView in a CoordinatorLayout

I'm fixing an app after the AndroidX migration, and I had a very odd bug that my ListView was not being loaded on the onCreate/onStart/onResume events:
A ListView is not displaying any data on OnCreate/OnStart after AndroidX migration
By matter of chance, I decided to "simplify" my layout and removed a LinearLayout that contained the ListView. After this change, the data was loaded properly because it seems LinearLayout was somehow blocking the getView event. However, after this change, the SearchView is being overlapped by the ListView, and I don't know how to put them in the right order (first the SearchView followed by the ListView).
This is how it looks now:
This is my code:
other_ruins.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"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<androidx.coordinatorlayout.widget.CoordinatorLayout
android:layout_weight="1"
android:layout_width="match_parent"
android:layout_height="match_parent">
<include layout="#layout/search_container" />
<ListView
android:id="#+id/lstOtherRuins"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
android:nestedScrollingEnabled="true"
android:layout_margin="8dp"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:choiceMode="singleChoice"
android:layout_below="#id/toolbar_container"
android:layout_gravity="left|start" />
</androidx.coordinatorlayout.widget.CoordinatorLayout>
<com.google.android.gms.ads.AdView
android:id="#+id/adView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:adSize="SMART_BANNER"
app:adUnitId="#string/banner_ad_unit_id" />
</LinearLayout>
search_container.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<FrameLayout
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/toolbar_container"
android:theme="#style/AppTheme.AppBarOverlay"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolbar"
app:theme="#style/ToolBarStyle"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/colorPrimary" />
<com.miguelcatalan.materialsearchview.MaterialSearchView
android:id="#+id/search_view"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</FrameLayout>
Regarding, the search_container I tested also using the AppBarLayout and crashed the app; therefore, it's not a solution.
Any idea how can I fix it? And why is this happening? If you know how to fix the previous issue and somehow call the getView event on the onCreate/onStart/onResume events is another solution.

You need to replace the FrameLayout in the search_container.xml with AppBarLayout as the AppBarLayout should wrap the Toolbar when you're using the Toolbar within the CoordinatorLayout
<?xml version="1.0" encoding="UTF-8" ?>
<com.google.android.material.appbar.AppBarLayout
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/toolbar_container"
android:theme="#style/AppTheme.AppBarOverlay"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolbar"
app:theme="#style/ToolBarStyle"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/colorPrimary" />
<com.miguelcatalan.materialsearchview.MaterialSearchView
android:id="#+id/search_view"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</com.google.android.material.appbar.AppBarLayout>

In my case, I needed to wrap my FrameLayout with a AppBarLayout make it work properly, when I didn´t do it, it duplicates the toolbar creating an strange shadow. This is the final change:
<?xml version="1.0" encoding="UTF-8" ?>
<com.google.android.material.appbar.AppBarLayout
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/toolbar_container"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolbar"
app:theme="#style/ToolBarStyle"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/colorPrimary" />
<com.miguelcatalan.materialsearchview.MaterialSearchView
android:id="#+id/search_view"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</FrameLayout>
</com.google.android.material.appbar.AppBarLayout>
Only one of them breaks the app.

Title in CollapsingToolbarLayout truncates on SearchView open

Whenever I open a SearchView within a CollapsingToolbarLayout, the page title gets squashed and truncated to 1 side for some reason rather than being positioned underneath the SearchView widget. Is there a way to prevent this from happening?

Your CollapsingToolbarLayout was covered by your RecyclerView, try to change the Main layout

Android scrolling toolbar with other combined views

In my android application I have Toolbar with SlidingLayer which that is simple library and extends from FrameLayout to make sliding on application. now when I try to use toolbar with this view I have to make it into FrameLayout, with this action scrolling my toolbar is not working.
I moved app:layout_scrollFlags="scroll|enterAlways" from <android.support.v7.widget.Toolbar to FrameLayout but scrolling it doesn't work again. for example my view with toolbar is:
Now how can I use app:layout_scrollFlags="scroll|enterAlways" and scrolling toolbar with this view?

How to scroll the webview in Tab Fragment down

My Webview is implemented in Tab Fragment. I would like to scroll web view to the bottom in fragment. Now i can't scroll down the webview in fragment. I'm using android studio to develop it. Below is my code:
Fragment XML:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
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">
<WebView
android:id="#+id/webview"
android:layout_width="371dp"
android:layout_height="516dp"
tools:layout_editor_absoluteX="-12dp"
tools:layout_editor_absoluteY="-3dp" />
</android.support.constraint.ConstraintLayout>
Activty:
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="#dimen/appbar_padding_top"
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:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/AppTheme.PopupOverlay">
<TextView
android:id="#+id/toolbar_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="20dp"
android:textColor="#ffffff"
android:layout_gravity="center" />
</android.support.v7.widget.Toolbar>
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"></android.support.v4.view.ViewPager>
<include layout="#layout/fragment_schedule" />

Alright try using RelativeLayout it will be shown full. You are facing this problem due to constraintLayout:
<?xml version="1.0" encoding="utf-8"?>
<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="match_parent"
android:paddingBottom= "5dp">
<WebView
android:id="#+id/webview"
android:layout_width="371dp"
android:layout_height="516dp"
tools:layout_editor_absoluteX="-12dp"
tools:layout_editor_absoluteY="-3dp" />
</RelativeLayout >

#Umair answer pointed me int the right direction but it missed a point. I did not have to change to relative layout to fix it, my webview was throwing a warning, that it is not correctly constrained (see the red underline)
After I changed width and height to
<WebView
android:id="#+id/webView"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
tools:layout_editor_absoluteY="1dp" />
the problem got fixed right away. Now it is possible that this problem shows up only in fragments but this is one way to fix it.

Is it possible to create swipeable toolbar?

I want to create a second toolbar with all the menu items directing to different activities instead of creating a viewpager with different fragments. I tried to look for example online but all the examples I found are related to viewpager with fragments or collapsing toolbar. Is it possible to have a "swipeable" toolbar so that all menu items can be displayed instead of putting some of the items on overflow button? The layout I have right now is as follows. Thank you so much.

You can nest a HorizontalScrollview inside your Toolbar layout:
<android.support.v7.widget.Toolbar
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<HorizontalScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<!-- Buttons -->
</LinearLayout>
</HorizontalScrollView>
</android.support.v7.widget.Toolbar>

I am thinking of using navigationview. The example of its implementation is in this link.
Or you can use the one suggested by mrsegev: use HorizontalScrollview in your Toolbar as it is also a view group.
