I've got this layout:

<android.support.v7.widget.CardView

    android:id="@+id/description_root_View"

    android:layout_height="wrap_content"

    android:layout_width="match_parent"

    app:cardCornerRadius="@dimen/CardView_CornerRadius"

    app:cardElevation="@dimen/CardView_elevation"

    app:cardUseCompatPadding="true"

    android:background="@color/escription_background"

    app:layout_constraintStart_toStartOf="parent"

    app:layout_constraintEnd_toEndOf="parent"

    app:layout_constraintTop_toTopOf="@id/SwipeView">



    <android.support.constraint.ConstraintLayout

        android:layout_width="match_parent"

        android:layout_height="match_parent"

        android:padding="@dimen/View_margins">



        <FrameLayout

            android:id="@+id/description_FrameLayout_profile"

            android:layout_width="@dimen/description_FrameLayout_profile"

            android:layout_height="@dimen/description_FrameLayout_profile"

            android:background="?selectableItemBackground"

            app:layout_constraintStart_toStartOf="parent"

            app:layout_constraintTop_toTopOf="parent">



            <ImageView

                android:id="@+id/description_ImageView_profile"

                android:layout_width="@dimen/description_ImageView_profile"

                android:layout_height="@dimen/description_ImageView_profile"

                android:src="@drawable/profile_photo"

                android:scaleType="fitCenter"

                android:layout_gravity="center"/>



            </FrameLayout>



    </android.support.constraint.ConstraintLayout>



</android.support.v7.widget.CardView>



   <View

    android:id="@+id/View_layer_over"

    android:layout_width="match_parent"

    android:layout_height="0dp"

    android:background="@color/fragment_tutorial_layer_background"

    android:elevation="@dimen/adapter_versus_CardView_elevation"

    android:clickable="true"

    app:layout_constraintTop_toTopOf="parent"

    app:layout_constraintBottom_toBottomOf="parent"/>

In the begining the View View_layer_over is a semi-transparent view that is on top of everything in my layout. When i press a button i wanna bring the description_FrameLayout_profile FrameLayout on top of the View_layer_over View. I have tried the View.bringToFront() method and ViewCompat.setTranslationZ(), after both of them i have called Parent.invalidate(), but none of them worked for me. I think it has something to do with the elevation attribute.

Any help would be highly appreciated. Thank you!

I'm not 100% sure that I understand exactly what you want, but what I'd do in this situation is have the ConstraintLayout be the parent/root view, which would contain your 'View_layer_over" view, and your CardView. If you set your constraints correctly, you'd get the behavior I think you want...
