Q:

SnackBar and fitsSystemWindow

I have an app that uses fitsSystemWindows to be able to draw an background behind Navigation- and Status-Bar - unfortunately the SnackBar seems to ignore the fitsSystemWindows=true from the container. I boiled the problem down to this minimal app:

the style:
<resources>

    <style name="AppTheme" parent="Theme.AppCompat.Light">

        <item name="android:windowBackground">@color/accent_material_dark</item>
        <item name="android:fitsSystemWindows">false</item>

        <item name="android:windowTranslucentStatus">true</item>
        <item name="android:windowTranslucentNavigation">true</item>
    </style>

</resources>

the layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                xmlns:tools="http://schemas.android.com/tools"
                android:layout_width="match_parent"
                android:layout_height="match_parent"

                android:fitsSystemWindows="true"
                tools:context=".MainActivity">

    <Button

            android:id="@+id/button"
            android:text="@string/hello_world"
            android:layout_width="match_parent"
            android:layout_height="match_parent"/>

</RelativeLayout>

the activity:
public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        findViewById(R.id.button).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(final View v) {
                Snackbar.make(v,"This Snackbar should fitSystemWindows",Snackbar.LENGTH_INDEFINITE).show();
            }
        });
    }

}

Anyone knows some workaround?
I published the minimal app to show the problem here:

A:

Snackbar will always look for a CoordinatorLayout to anchor itself in: when you don't have one, it uses the full content view (which in your case, includes the area under the status bar) - adding a CoordinatorLayout that has fitsSystemWindows=true should do it.﻿
