How to set custom toolbar background in android

Hey guys I am using custom toolbar in my project. When I try to scroll view it goes behind the toolbar and see all item. I made a short video please have a look.
toolbar.xml
<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

/// more item
</androidx.core.widget.NestedScrollView>
</androidx.coordinatorlayout.widget.CoordinatorLayout>
I tried to put white background on toolbar, it solve the problem when scroll but another occur. When my searchview collapse its invisible. I think it's goes behind white background. I also made a short video for that.
<androidx.appcompat.widget.Toolbar

android:layout_marginTop="20dp"

android:background="#color/white"
app:theme="#style/ActionBarTheme">

<item name="actionBarStyle">#style/ActionBarStyle</item>
<item name="actionMenuTextAppearance">#style/MenuItemTextAppearance</item>
<item name="android:textColorPrimary">#color/aqua</item>
</style>
Any idea How can I fix this problem?

TabLayout displays unwanted "borders"

I'm using TabLayout, and I'm getting these weird borderlines and I can't tell why.
I'm talking about those diagonal ones in grey coming from the sides - how can I remove them?

Android toolbar showing shadow when it shouldn't

I'm creating an app and I got my layout defined like this:
<android.support.design.widget.CoordinatorLayout
android:id="#+id/coordinator_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize">
<include layout="#layout/toolbar"/>
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
<android.support.design.widget.FloatingActionButton
android:id="#+id/floating_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="16dp"
app:backgroundTint="#color/primary_green">
</android.support.design.widget.FloatingActionButton>
</android.support.design.widget.CoordinatorLayout>
And toolbar.xml looks like this:
<?xml version="1.0" encoding="utf-8"?>
<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="?attr/actionBarSize"
app:layout_scrollFlags="scroll|enterAlways"
app:theme="#style/AppTheme.ToolbarTheme">
<ImageView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="center"
android:layout_margin="10dp"
android:src="#drawable/app_logo"/>
</android.support.v7.widget.Toolbar>
And AppTheme.ToolBar theme is defined as:
<style name="AppTheme.ToolbarTheme">
<item name="android:background">#color/primary_white</item>
<item name="android:windowContentOverlay">#null</item>
<item name="android:elevation">0dp</item>
<item name="elevation">0dp</item>
</style>
I've even tried setting the elevation in code, still the toolbar shadow is visible. How can I disable it?

You're getting shadow, because AppBarLayout is giving shadow for Toolbar too.
You should remove elevation also from it.

android.support.design.widget.tablayout Tab Indicator colour

I am using TabLayout and a View Pager to show multiple tabs. I want to change the selected tab indicator. I have used app:tabIndicatorColorbut the colour is not changing. It shows a greenish colour. I have read that by default the tabIndicator colour is set tocolor/accent, however the greenish colour is not my accent colour.
My xml is as below:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_height="match_parent"
android:layout_width="match_parent">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/primary"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:background="#color/primary"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
/>
<android.support.design.widget.TabLayout
android:id="#+id/tab_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabGravity="fill"
app:tabIndicatorColor="#android:color/white"
app:tabSelectedTextColor="#android:color/white"
app:tabTextColor="#color/primary_light"
/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/view_pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>
<android.support.design.widget.NavigationView
android:id="#+id/navigation_view"
android:layout_height="match_parent"
android:layout_width="wrap_content"
android:layout_gravity="start"
app:headerLayout="#layout/header_layout"
app:menu="#menu/menu_drawer"
/>
What am I missing?

<android.support.design.widget.TabLayout
android:id="#+id/tabs"
app:tabGravity="fill"
app:tabMode="fixed"
android:background="#color/material_blue_grey_800"
app:tabIndicatorColor="#color/orange"
app:tabSelectedTextColor="#color/orange"
app:tabTextColor="#color/white"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</android.support.design.widget.TabLayout>
It can help You.
app:tabIndicatorColor="#color/orange" here is the line which change the color.

You can try the following customization for your TabLayout,
<android.support.design.widget.TabLayout
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#id/pages_tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:minHeight="?attr/actionBarSize"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:tabIndicatorColor="#android:color/white"
app:tabIndicatorHeight="4dp"/>
This should solve the indicator color!

According to the source code of TabLayout, the tabTextColor must reference a selector color instead of a single color. This is the part in the source code where it uses getColorStateList:
if (a.hasValue(R.styleable.TabLayout_tabTextColor)) {
// If we have an explicit text color set, use it instead
mTabTextColors = a.getColorStateList(R.styleable.TabLayout_tabTextColor);
}
so you should define your colors in file like this for example res/color/your_colors.xml:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_selected="true"
android:color=""#color/primary_light"/>
<item android:color="#0000ff"/>
</selector>

you can set color Programmatically like
tabLayout.setSelectedTabIndicatorColor(R.color.black);

Struggling with toolbar using android support design library

I am tying to get transparent toolbar over RecyclerView contains custom Relative Layout i called it customHeader . my layout in the main activity is like:

Check how u style is applied
Where u set it to transparent (alpha?)
View.getBackground().setAlpha(..) ;
