scrolling doesn't work even when using <ScrollView> (Android Studio)

Question

I've tried every solution I could find on different sites, but couldn't find anything, hopefully someone here could help me. There are no errors, just doesn't work to scroll.

<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="385dp"
    android:layout_height="540dp"
    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"
    tools:context="gino.navigationface.bar_position"
    tools:showIn="@layout/app_bar_bar_position">


    <ScrollView

        android:id="@+id/scrollView"

        <LinearLayout

        </LinearLayout>
    </ScrollView>
</LinearLayout>

If needed I could post screenshots of the app

Answer 1

I found the problem in the app_bar_bar_position.xml, I placed the android:background in the which made the scrolling not work

< android.support.design.widget.CoordinatorLayout 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:fitsSystemWindows="true" tools:context="gino.navigationface.bar_position" android:background="@drawable/background_blank">

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.AppBarOverlay">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        app:popupTheme="@style/AppTheme.PopupOverlay" />

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

<include layout="@layout/content_bar_position" />
