Display content behind state and navigation bar

Question

This seems like a duplicate question, but I can't do it. I want a completely transparent (not translucent) status bar, as well as a navigation bar, and want the content to appear behind them.

activity_details.xml

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/colorPrimary"
    tools:context="com.bitspilanidvm.bosm2017.DetailsActivity">

<ImageView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:src="@drawable/q"
    android:scaleType="centerCrop"/>

</LinearLayout>

v21 styles.xml

<resources>

<!-- Theme for API level > 21 -->
<style name="AppTheme" parent="AppBaseTheme">
     <!--Customize your theme here. -->
    <item name="android:statusBarColor">@android:color/transparent</item>
    <item name="android:navigationBarColor">@android:color/transparent</item>
</style>

In action java file

getWindow().getDecorView().setSystemUiVisibility(
        View.SYSTEM_UI_FLAG_LAYOUT_STABLE |
               View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
        );

This is what I get.

How to get content from the navigation bar?

If I add

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

to my styles.xml

This is what i get

As you can see, the content extends beyond the navigation bar, but for this the navigation bar must be translucent.

Is there any solution for this?

FLAG_LAYOUT_NO_LIMITS . Android KitKat API. :

 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        Window window = getWindow(); 
     window.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
    }

API ViewCompat.setOnApplyWindowInsetListener , android:fitsSystemWindows="true", . .

ViewCompat.setOnApplyWindowInsetsListener(toolbar, (v, insets) -> {
    ViewGroup.MarginLayoutParams params = (ViewGroup.MarginLayoutParams) v.getLayoutParams();
    params.topMargin = insets.getSystemWindowInsetTop();
    return insets.consumeSystemWindowInsets();
});

    for (int index = 0; index < childCount; ++index)
        getChildAt(index).dispatchApplyWindowInsets(insets);
