Recyclerview scrollToPosition 不适用于 NestedScrollView ?有吗?

Bin*_*aby 5 android android-scrollview android-recyclerview nestedscrollview android-nestedscrollview

所以我有Recyclerview一个NestedScrollView. 当我说recycleview.scrollToPosition(X)或者recycleview.getLayoutManager().scrollToPosition(X)它根本不起作用时。

如果我recycleviewnestedScrollView它移出它工作正常,但我不能这样做,因为布局结构!任何的想法?

scrollingView.requestChildFocus(recyclerView,recyclerView);

让你的回收视图像这样

<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>

和java代码

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);
