Android Lollipop: ImageView ignoring fitsSystemWindows attribute (transparent status bar)

Question

I'm currently working on an app for which I want to enable a transparent status bar. I want an ImageView (which I require for its scaleType attribute) to cover the entirety of the screen so that the image will show below the status bar. Here's my layout:

<android.support.v4.widget.DrawerLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true">
    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fitsSystemWindows="true">
        <ImageView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:adjustViewBounds="true"
            android:fitsSystemWindows="true"
            android:scaleType="centerCrop"
            android:src="@drawable/picture" />

        <android.support.v7.widget.Toolbar
            (...toolbar stuff...)
        />

        (...some other stuff...)

    </RelativeLayout>

    <include layout="@layout/drawer" />
</android.support.v4.widget.DrawerLayout>

As you can see, it's a regular DrawerLayout. Notice that the DrawerLayout, the RelativeLayout and the ImageView all have the fitsSystemWindows attribute set to true.

My problem is: If I set a background resource (like a color or a picture) to either the DrawerLayout or the RelativeLayout in the above code, I can see that color or picture "below" the status bar, exactly as I want it, but the ImageView's 'src' drawable is always shown under it, as if it ignored the fitsSystemWindows attribute completely.

I have the following attributes in my theme:

<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">@color/primary_dark</item>

With primary_dark being a semitransparent black (this shouldn't matter anyway, since as I said, this seems to be an issue exclusive to my ImageView. The transparent status bar works perfect for either the DrawerLayout or the RelativeLayout.

Answer 1

This works perfectly for me

You have android:fitsSystemWindows="true"in every viewGroup params. Try to left only one in ImageView.

Or completely remove all of them.

Answer 2

fitSystemWindows

does not work in RelativeLayout. Use a FrameLayout or a ViewGroup extending FrameLayout
