Using windowTranslucentStatus with CollapsingToolbarLayout

Question

I\'m trying to get a similar effect to what is seen on google play.

I\'ve got the below layout to show a transparent toolbar with an image behind it. When the user s

Answer 1

Once the status bar is transparent and the free to use by the activity, the toolbar is pushed top to occupy that space. To fix this you need to manually move the toolbar to the original spot.

Add the below tags to the "android.support.v7.Widget.Toolbar" view :

android:layout_height="48dp" // Whatever the height of the toolbar you want
android:layout_marginTop="-48dp" // Negative of the height of the toolbar

Answer 2

There has now been an update to the design library. I'm guessing that the issue posted above was a bug.

If you update the design library to the latest version this issue no longer occurs.

I have now removed all fitsSystemWindows="true" except for the ImageView (as that needs to display under the status bar).

I have also removed the minus padding from the Toolbar.

This is my theme for 21+

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:windowTranslucentStatus">true</item>
    <item name="android:windowActionBarOverlay">true</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:textColorPrimary">@android:color/white</item>
</style>

It all works as expected now

The best way to achieve this is like Stimsoni said

Add android:fitsSystemWindows="true" to the CoordiatorLayout, AppBarLayout and ImageView

<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/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">

<android.support.design.widget.AppBarLayout
    android:id="@+id/appBar"
    android:fitsSystemWindows="true"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

    <android.support.design.widget.CollapsingToolbarLayout
        android:id="@+id/collapsing_toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:contentScrim="?attr/colorPrimary"
        app:layout_scrollFlags="scroll|exitUntilCollapsed|snap">

        <ImageView
            android:id="@+id/background"
            android:layout_width="match_parent"
            android:layout_height="256dp"
            android:scaleType="centerCrop"
            android:fitsSystemWindows="true"
            app:layout_collapseMode="parallax"
            android:alpha="0.75"
            android:src="@drawable/foo"/>

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
            app:layout_collapseMode="pin"/>
    </android.support.design.widget.CollapsingToolbarLayout>        
</android.support.design.widget.AppBarLayout>...

I have the same issue, but there is one thing i know.

If you what to have a transparent statusbar on a normal toolbar, you need to add a 16dp padding top.

Answer 5

Add fitsSystemWindows to layout and set to true.

Update

Sorry for my incomplete answer. You should add fitsSystemWindows="true" to layout xml like below codes.

<android.support.design.widget.CoordinatorLayout
    android:id="@+id/main"
    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:fitsSystemWindows="true">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recyclerView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior" />

    <android.support.design.widget.AppBarLayout
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        android:background="@color/background_material_dark"
        android:fitsSystemWindows="true">

        <android.support.design.widget.CollapsingToolbarLayout
            android:id="@+id/collapsingToolbarLayout"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:minHeight="?attr/actionBarSize"
            app:layout_scrollFlags="scroll|enterAlways|enterAlwaysCollapsed"
            app:statusBarScrim="#09b"
            app:contentScrim="#09f"
            android:fitsSystemWindows="true">

            <ImageView
                android:id="@+id/img"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:src="@drawable/location_banner"
                app:layout_collapseMode="parallax"
                app:layout_collapseParallaxMultiplier="0.7"
                android:fitsSystemWindows="true"/>

            <android.support.v7.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_height="?attr/actionBarSize"
                android:layout_width="match_parent"
                app:layout_collapseMode="pin"
                android:fitsSystemWindows="true"
                app:theme="@style/ThemeOverlay.AppCompat.ActionBar"
                app:popupTheme="@style/ThemeOverlay.AppCompat.Dark"/>

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

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

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

Answer 6

Just Change the color of status bar in Styles.XML(v21)

<item name="android:statusBarColor">@android:color/transparent</item>

or remove the above line in that XML it work perfect.
