Answer 1

use FrameLayout instead of LinearLayout and add this to your FrameLayout of the fragment

Answer 2

This might come from the default behaviour of the CoordinatorLayout. I also assume that you add your fragments in the frameLayout frameCheck. In your app bar code layout, replace

<FrameLayout
    android:id="@+id/framecheck"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
</FrameLayout>

with :

<FrameLayout
    android:id="@+id/framecheck"
    app:layout_behavior="android.support.design.widget.AppBarLayout$ScrollingViewBehavior"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />
