SnackBar and fitsSystemWindow

Question

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:

problem

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?

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.

Would this cascade down from Fragment? I have a fragment where I spawn this Snackbar though – Neon Warge Jun 22 '17 at 05:56
@NeonWarge - You mean cascade up from a Fragment whose view is contained within a `CoordinatorLayout`? Yup. – ianhanniballake Jun 23 '17 at 05:54
yes, in fact, there is something messing it up. It doesn't respect that attribute for me :/ Its a ViewPager on an activity with 4 fragments. – Neon Warge Jun 23 '17 at 05:59

You can also use the following line in place of any CoordinatorLayout in Snackbar declaration with findViewById(android.support.design.R.id.design_navigation_view) .

Well The correct answer is add android:paddingbottom="50dp" to your CoordinatorLayout although i'm not sure if all navigation bar size's is 50 dp

navigation bar size is not always same, so if you want to go this way, you need to check [windowInsets](https://developer.android.com/reference/android/view/WindowInsets.html) – yshrsmz Apr 11 '18 at 07:21
