Note :- when i used other view insted of RecyclerView than it work perfectly as i want like when i click and drag that view CoordinatorLayout not move but i need recycler view there to show list :(

Answer 1

Yup , I got the answer by myself

Just stop scroll of RecyclerView and it just work what i want

                 <android.support.v7.widget.RecyclerView
                        android:id="@android:id/list"
                        android:layout_width="match_parent"
                        android:layout_height="match_parent"
                        android:background="@android:color/transparent"
                        android:cacheColorHint="@android:color/white"
                        android:descendantFocusability="blocksDescendants"
                        android:divider="@android:color/darker_gray"
                        android:dividerHeight="@dimen/divider_height"
                        android:drawSelectorOnTop="true"
                        android:nestedScrollingEnabled="false"
                        android:overScrollMode="never"
                        android:fadeScrollbars="false"/> 

also i used in java file

        mListView = (RecyclerView) rootView.findViewById(android.R.id.list);
        mListView.setNestedScrollingEnabled(false);
        mListView.setOverScrollMode(ListView.OVER_SCROLL_NEVER);
        mListView.stopScroll();

mListView.stopScroll() This is real game changer But i am not happy that no one try to solve my prob except Bruno Ferreira :( Thanks Bruno for help

So remove recycleview from your layout behavior parent. Because the recycleview isnt inside the layout behavior parent he dont do the scroll flag. If this not Works the oter way is put the CoordinatorLayout inside other layout like a LinearLayout and recycleview outside CoordinatorLayout but inside LinearLayout.

Note: It's my idea i don't know if it Works.
