Lagginess happening while scrolling page when using Coordinator layout+AppBarLayout+CollapsingToolbarLayout in android

I'm using CoordinatorLayout + AppBarLayout + CollapsingToolbarLayout in my fragment layout. The code snipper for this layout file is below:

and One Video link for clear picture of problem.
I'm using latest support library version i.e. 26.0.2.
Can someone tell me why this problem is happening and what the solution for that??

MPAndroidChart Line Chart problems

I'm trying to show several line charts but the scrolling is not working for the page where the charts should be shown. I use a viewpager which is inside of a Coordinator Layout.
I'd like to achieve too the following things:
Quit curve's line
Quit the colors labels from the Legend
I know that Coordinator Layout and Viewpager sometimes need some tricky workaround, but until this moment I couldn't find the solution. I need to add more charts...
The main xml:
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/coordinator_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar_layout"
android:layout_width="match_parent"
android:layout_height="112dp"
android:background="#color/colorPrimary"
android:elevation="#dimen/elevation_toolbar"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
android:fitsSystemWindows="true">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsing_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:contentScrim="#color/colorPrimary"
app:expandedTitleMarginEnd="64dp"
app:expandedTitleMarginStart="48dp"
app:layout_scrollFlags="scroll|enterAlways"
android:fitsSystemWindows="true">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?actionBarSize"
android:layout_marginLeft="#dimen/list_toolbar_side_margin"
android:layout_marginRight="#dimen/list_toolbar_side_margin"
app:layout_collapseMode="pin" />
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
style="#style/AppTabLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
app:tabGravity="fill"
app:tabMode="fixed"
app:tabTextAppearance="#style/AppTabTextAppearance"/>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<ProgressBar
android:id="#+id/progress_bar_garden"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:visibility="gone"/>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
/>
And the charts fragment xml:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ProgressBar
android:id="#+id/progress_bar_charts"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:visibility="gone" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<com.github.mikephil.charting.charts.LineChart
android:id="#+id/temp_chart"
android:layout_width="#dimen/show_plant_chart_width"
android:layout_height="#dimen/show_plant_chart_height"
android:layout_marginStart="#dimen/show_plant_chart_margin_start" />
<com.github.mikephil.charting.charts.LineChart
android:id="#+id/humidity_chart"
android:layout_width="#dimen/show_plant_chart_width"
android:layout_height="#dimen/show_plant_chart_height"
android:layout_marginStart="#dimen/show_plant_chart_margin_start"
android:layout_marginTop="#dimen/show_plant_chart_margin_top" />
</LinearLayout>
</RelativeLayout>

I resolved this issue using a recycleView. It appears that MPAndroidChart Line Chart has a problem with ScrollView. I don't why.

When I scroll the 2 icons are hide behind the image instead of setting inside the toolbar. Any idea how can i do this, I look into many examples but now working for me. I have implemented onOffsetChanged method of Appbarlayout and try to play with animation but didn't worked for me.

There is an accepted answer in Android: dynamically change ActionBar icon? refer this. You can get image from your image view and reduce its size to your requirement and can change icon using homeItem.setIcon(your image);

AppBarLayout + TabLayout + CollapsingToolbarLayout + SwipeToRefresh

I met a lot of issues related with my problem but nobody I found wanted the behaviour I'm looking for.
I want a view pager with tabs and app bar, when the contained fragments are scrollable and are scrolled (toward bottom), I want the app bar to disapear but leave the tabs, when scrolled toward top, to re-apear. some of these fragments contain a SwipeToRefresh Layout (sometimes it causes problems).
I tried a lot of configurations that always leave something wrong.
for now I don't have the collapsing effect (it's always hidden)

I don't know exactly what I've done but from the time I started write this question the refreshLayout prevent my List from going up (it refreshes instead)..
Thanks

android:layout_height="match_parent"
android:scrollbars="vertical" />
</android.support.v4.widget.SwipeRefreshLayout>
</FrameLayout>

If you don't want parallax effect, you don't need to use CollapsingToolbarLayout.
Most important configuration:
In Toolbar, set app:layout_scrollFlags="scroll|enterAlways".
In ViewPager, set app:layout_behavior="#string/appbar_scrolling_view_behavior".
And layout should look like this:
<android.support.design.widget.CoordinatorLayout>
<android.support.design.widget.AppBarLayout>
<android.support.v7.widget.Toolbar/>
<android.support.design.widget.TabLayout/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager/>
<android.support.design.widget.FloatingActionButton/>
</android.support.design.widget.CoordinatorLayout>
Move ProgressWheel out of your SwipeRefreshLayout to fix your problem that SwipeRefreshLayout can't refresh.
