MY CODE (and more): I have a Coordinator Layout as follows
<android.support.design.widget.CoordinatorLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true">
    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:fitsSystemWindows="true">
        <android.support.design.widget.CollapsingToolbarLayout
            android:id="@+id/collapse_toolbar"
            android:layout_width="match_parent"
            android:layout_height="280dp"
            android:fitsSystemWindows="true"
            app:contentScrim="@color/transparent"
            app:layout_scrollFlags="scroll|exitUntilCollapsed">
            <include layout="@layout/top" /> <!-- A RelativeLayout -->
            <android.support.v7.widget.Toolbar
                android:id="@+id/MyToolbar"
                android:layout_width="match_parent"
                android:layout_height="64dp"
                app:layout_collapseMode="parallax">
            </android.support.v7.widget.Toolbar>
        </android.support.design.widget.CollapsingToolbarLayout>
    </android.support.design.widget.AppBarLayout>
    <FrameLayout
        android:id="@+id/content"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior">
        <!-- Main content here -->
    </FrameLayout>
</android.support.design.widget.CoordinatorLayout>
Inside the frame layout I am inflating a custom view with an edit text which is placed at the bottom. The edit text and custom view show up fine.
I have defined android:windowSoftInputMode="adjustResize|stateHidden" in the manifest.
MY PROBLEM: While tapping on the edit text to bring up the softkeyboard, it overlaps the content beneath instead of resizing the FrameLayout. I just could not get the FrameLayout to resize when the soft keyboard comes up. Any help will be appreciated
THINGS I TRIED:
- Updated design support library to 22.2.1
 - Added android:layout_gravity="fill_vertical" as an attribute in FrameLayout.
 
Try this
your_layout.xml
<RelativeLayout
    android:fitsSystemWindows="true" > <!-- Crucial! -->
    <android.support.design.widget.CoordinatorLayout>
        ...
        <android.support.v7.widget.RecyclerView />
        ...
    </android.support.design.widget.CoordinatorLayout>
</RelativeLayout>
AndroidManifest.xml
<activity
    android:name=".YourActivity"
    android:windowSoftInputMode="adjustResize"> <!-- Crucial! -->
</activity>
    This is just another bug in the design support lib and it seems they don't plan to fix it any time soon:
Confirmed, but probably won't be fixed any time soon. adjustResize has a few good use-cases, but using AppBarLayout with CollapsingToolbarLayout with it is not one of them.
It's disturbing that nobody tried to add a EditText to a CoordinatorLayout with android:windowSoftInputMode="adjustResize" while developing the design support lib.
I'm using this for solving CoordinatorLayout bug
in onCreateDialog in BottomSheetFragment
KeyboardUtil(getActivity(), view);
or
For Activity use
new KeyboardUtil(this, findViewById(R.id.fragment_container));
by using this Util class

My Layout
<android.support.design.widget.CoordinatorLayout>
    <android.support.design.widget.AppBarLayout>
        <android.support.design.widget.CollapsingToolbarLayout>
            <ImageView>
            <android.support.v7.widget.Toolbar>
        <android.support.design.widget.CollapsingToolbarLayout>
    <android.support.design.widget.AppBarLayout>
    <android.support.v4.widget.NestedScrollView>
    <android.support.design.widget.FloatingActionButton>
<android.support.design.widget.CoordinatorLayout>
I had the exact same problem. I figured out, that if i use something within the e.g. NestedScrollView or within a FrameLayout i would assume as well that handles the Scroll itself, the CoordinatorLayout does not adjustResize / behave the way you want. The adjustResize|adjustPan settings within the Manifest are ignored.
For me this was very hard to figure out, because i wrote a few (combined-) Views myself that contained RelativeLayout or ScrollViews and such.
If i just avoid using RelativeLayouts or anything else than NestedScrollView to handle the view scrolling, it behaves the way, at least i wanted it to. 
But i think, there is a Bug within CoordinatorLayout or a behaviour we all need to understand better to avoid this type of problems...
Maybe this is useful to know for someone...
My Settings are:
- support/design/appcompat : 22.2.1
 - no need for layout_gravity
 
Hi I had the same problem and I only put
        android:windowSoftInputMode="adjustPan"
in yout manifest for the activity concerned and the keyboard moves up the view accordingly now
adjustResize not work with
app:layout_behavior="@string/appbar_scrolling_view_behavior"
Remove this line:
app:layout_behavior="@string/appbar_scrolling_view_behavior" 
    A shortened version from KeyboardUtil, add this to your activity:
getWindow().getDecorView().getViewTreeObserver()
        .addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
    public void onGlobalLayout() {
        Rect r = new Rect();
        getWindow().getDecorView().getWindowVisibleDisplayFrame(r);
        rootView.setPadding(0, 0, 0,
                activity.getResources().getDisplayMetrics().heightPixels - r.bottom);
    }
});
    Don't use CoordinatorLayout as a root layout if you use EditText views on your NestedScrollView
<androidx.constraintlayout.widget.ConstraintLayout
  android:fitsSystemWindows="true">
  <androidx.coordinatorlayout.widget.CoordinatorLayout>
    <com.google.android.material.appbar.AppBarLayout>
      <com.google.android.material.appbar.CollapsingToolbarLayout/>
    </com.google.android.material.appbar.AppBarLayout>
    <androidx.core.widget.NestedScrollView>
    <Editext/>
    <androidx.core.widget.NestedScrollView/>
  </androidx.coordinatorlayout.widget.CoordinatorLayout>
</androidx.constraintlayout.widget.ConstraintLayout>
