Recyclerview scrollToPosition doesn't work with NestedScrollView ? Is there anyway?

问题:

So I have a Recyclerview within a NestedScrollView. When I say recycleview.scrollToPosition(X) or recycleview.getLayoutManager().scrollToPosition(X) it doesn't work at all.

If I move the recycleview out from the nestedScrollView it works fine, but I can't do it, because of the layout structure! Any idea?

scrollingView.requestChildFocus(recyclerView,recyclerView); 

tried this, but not focusing on a certain position

回答1:

make your recyclerview like this

<LinearLayout       android:id="@+id/ll2"       android:focusableInTouchMode="true"       android:layout_width="match_parent"       android:layout_height="wrap_content">            <android.support.v7.widget.RecyclerView               android:layout_width="match_parent"               android:layout_height="wrap_content"               android:layout_margin="5dp"               android:clipToPadding="false"               android:visibility="visible"/>  </LinearLayout> 

and the java code

ItemsArrayList.add(0, items5); adapter.notifyDataSetChanged(); ViewCompat.setNestedScrollingEnabled(recyclerView,false); NestedScrollView nestedScrollingView = (NestedScrollView) findViewById(R.id.nestedScrollingView); LinearLayout linearLayout = (LinearLayout) findViewById(R.id.ll2); float y = fcRecyclerView.getChildAt(0).getY(); float z =linearLayout.getY(); nestedScrollingView.smoothScrollTo(0, (int) z);
