Navigation Drawer Semi-Transparent Over Status Bar Not Working

Navigation Drawer semi-transparent over status bar not working

Your status bar background is white, the background of your drawer LinearLayout. Why? You are settings fitsSystemWindows="true" for your DrawerLayout and the LinearLayout inside it. This causes your LinearLayout to expand behind the status bar (which is transparent). Thus, making the background for the drawer part of the status bar white.

If you don't want your drawer to extend behind the status bar (want to have a semi-transparent background for the whole status bar), you can do two things:

1) You can simply remove any background value from your LinearLayout and color the background of your content inside it. Or

2) You can remove fitsSystemWindows="true" from your LinearLayout. I think this is a more logical and cleaner approach. You will also avoid having a shadow being cast under the status bar, where your navigation drawer doesn't extend.

If you want your drawer to extend behind the status bar and have a semi-transparent, status bar sized overlay, you can use a ScrimInsetFrameLayout as a container for your drawer content (ListView) and set the status bar background using app:insetForeground="#4000". Of course, you can change #4000 to anything you want. Don't forget to keep fitsSystemWindows="true" here!

Or if you don't want to overlay your content and only display a solid color, you can just set the background of your LinearLayout to anything you want. Don't forget to set the background of your content separately though!

EDIT: You no longer need to deal with any of this. Please see Design Support Library for a times easier Navigation Drawer/View implementation.

Navigation Drawer Over Status Bar In Nougat?

You are having a colored status bar. So navigation drawer is not visible behind it. Make your Status bar transparent and then it will be there.

<!-- Make the status bar traslucent -->
<style name="AppTheme" parent="AppTheme.Base">
    <item name="android:windowTranslucentStatus">true</item> // add this item tag inside your Theme Styles.xml and Styles(v21).xml:
</style>

DrawerLayout with completely transparent status bar

Set NavigationView's insetForeground to transparent

    <com.google.android.material.navigation.NavigationView
        android:id="@+id/nv_navigation_drawer"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        app:insetForeground="@android:color/transparent" />

NavigationView and Translucent Status Bar

Look at this:

So the files are:

values:

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>
    <style name="AppTheme.NoActionBar">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
    </style>
    <style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />
    <style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />

</resources>

values-v21

<resources>
    <style name="AppTheme.NoActionBar">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
        <item name="android:windowDrawsSystemBarBackgrounds">true</item>
        <item name="android:statusBarColor">@android:color/transparent</item>
    </style>
</resources>

and MainActivity layout:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"

    tools:openDrawer="start">

    <android.support.design.widget.CoordinatorLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fitsSystemWindows="true">

        <android.support.design.widget.AppBarLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"

                android:background="?attr/colorPrimary"
                app:popupTheme="@style/AppTheme.PopupOverlay" />

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

        <RelativeLayout

            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:paddingBottom="@dimen/activity_vertical_margin"
            android:paddingLeft="@dimen/activity_horizontal_margin"
            android:paddingRight="@dimen/activity_horizontal_margin"
            android:paddingTop="@dimen/activity_vertical_margin"
            app:layout_behavior="@string/appbar_scrolling_view_behavior">

            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Hello World!" />
        </RelativeLayout>

        <android.support.design.widget.FloatingActionButton
            android:id="@+id/fab"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="bottom|end"
            android:layout_margin="@dimen/fab_margin"
            android:src="@android:drawable/ic_dialog_email" />

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

    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/nav_header_main"
        app:menu="@menu/activity_main_drawer" />

</android.support.v4.widget.DrawerLayout>

and the result:

nav_header:

</LinearLayout>

android - Transparent Navigation Bar but not Status Bar

Not exactly what I wanted but I found a workaround using Translucent Navigation Bar. The final code looks something like this:

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT){

        //set navigation bar translucent
        Window window = getWindow();
        window.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION, WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
        //now the status bar is translucent too, which we have to fix

        //first we get status bar height
        int statusBarHeight = 0;
        int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
        if (resourceId > 0) {
            statusBarHeight = getResources().getDimensionPixelSize(resourceId);
        }

        //then set it as top padding for the main layout
        ConstraintLayout mainLayout = (ConstraintLayout) findViewById(R.id.mainLayout);
        mainLayout.setPadding(0,statusBarHeight,0,0);
    }

Where top padding is added to the main layout of the activity.

If anyone knows how to do something similar with transparent navigation bar, perfect, but otherwise I am happy with my solution.

Android Status Bar transparent with Navigation Drawer - Appbar elevation

Add this line in toolbar

app:elevation="0dp"

status bar colour shows white not transparent while using navigation drawer under status bar in Android Kitkat 4.4 version

For API 21+

<style name="AppTheme" parent="android:Theme.Holo.NoActionBar.TranslucentDecor">
    ...
</style>

For API level 19+

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="android:windowTranslucentStatus">true</item>
</style>

Also your layout should have android:fitsSystemWindows="false"

NOTE: In Android KitKat you cannot change the color of the status bar except if you use the following solution because only in Lollipop Google introduced the attribute statuBarColor

So for that you need to check this transparent status bar in KITKAT
