Below is my code:-

  <android.support.design.widget.CoordinatorLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/transparent"
    android:fitsSystemWindows="true">

    <android.support.design.widget.AppBarLayout
        android:id="@+id/appbarlayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@android:color/transparent"
        app:elevation="0dp">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="@android:color/transparent" />
    </android.support.design.widget.AppBarLayout>


    <FrameLayout
        android:id="@+id/content_frame"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@+id/appbarlayout"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"
    />


</android.support.design.widget.CoordinatorLayout>

this gives me transparent toolbar as expected, As below:- But my Framelayout overlap on toolbar so I tried

1. to give top margin to Framelayout

2. using ' app:layout_behavior="@string/appbar_scrolling_view_behavior" '

this code worked and my FrameLayout is not overlaping but my toolbar is turning to white_color.

new Output is as below

Please help !. what's making my toolbar to be white from transparent background.

This will work

• Add a RelativeLayout and give background image to that
• Inside that you can have AppBarLayout and FrameLayout with android:layout_below="@+id/appbarlayout"

Example:

<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_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/transparent"
    android:fitsSystemWindows="true">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@drawable/amanda">

        <android.support.design.widget.AppBarLayout
            android:id="@+id/appbarlayout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@android:color/transparent"
            app:elevation="0dp">

            <android.support.v7.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                android:background="@android:color/transparent" />
        </android.support.design.widget.AppBarLayout>


        <FrameLayout
            android:id="@+id/content_frame"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_below="@+id/appbarlayout"
            android:background="#332"
            android:orientation="vertical" />
    </RelativeLayout>
</android.support.design.widget.CoordinatorLayout>
