I am getting this error on the line -

View view = recycler.getViewForPosition(position);

Here, in this method of custom LinearLayoutManager -

  private void measureScrapChild(RecyclerView.Recycler recycler, int position, int widthSpec,
                                   int heightSpec, int[] measuredDimension) {



        View view = recycler.getViewForPosition(position);
        if (view != null) {
            RecyclerView.LayoutParams p = (RecyclerView.LayoutParams) view.getLayoutParams();
            int childWidthSpec = ViewGroup.getChildMeasureSpec(widthSpec,
                    getPaddingLeft() + getPaddingRight(), p.width);
            int childHeightSpec = ViewGroup.getChildMeasureSpec(heightSpec,
                    getPaddingTop() + getPaddingBottom(), p.height);
            view.measure(childWidthSpec, childHeightSpec);
            measuredDimension[0] = view.getMeasuredWidth() + p.leftMargin + p.rightMargin;
            measuredDimension[1] = view.getMeasuredHeight() + p.bottomMargin + p.topMargin;
            recycler.recycleView(view);

        }
    }

Previously, it was working well. I recently changed the targetSdkVersion to 23 (Marshmallow), and as well as the versions of support lib. May be the issue is for the same reason.

Please guide me, how to fix this.

No, I am not using notifyDataSetChanged anywhere. but I am calling viewTreeObserver on RecyclerView, — Narendra Singh, Apr 29 '16 at 09:16
Will it be affected if you use [`findViewByPosition`](http://developer.android.com/intl/es/reference/android/support/v7/widget/LinearLayoutManager.html#findViewByPosition%28int%29) instead ? — Shree Krishna, Apr 29 '16 at 09:23
no, I don't think. As the position I am getting there, in the method - **measureScrapChild** is 0 — Narendra Singh, Apr 29 '16 at 09:24
use findViewByPosition() on recyclerView.getLinearlayoutManager(). It will give the view at a particular index. — Saritha G, Apr 29 '16 at 09:26
I don't have RecyclerView object inside **measureScrapChild()**. What I have there is - object of RecyclerView.Recycler. Thats why, I am unable to get LayoutManager. How to use **findViewByPosition** then. — Narendra Singh, Apr 29 '16 at 09:30
You may know that `getViewForPosition` method should be used by `RecyclerView.LayoutManager` where `findViewByPosition()` method easily available. — Shree Krishna, Apr 29 '16 at 09:37
let me post that method too. Hope, that will make you easy to understand. — Narendra Singh, Apr 29 '16 at 09:48
added the method @ShreeKrishna. Please check, I don't have RecyclerView there. — Narendra Singh, Apr 29 '16 at 10:08
@DroidWormNarendra Where this method belongs ? Please reply fast And sorry to inform I am leaving now and in leave for 2 days.. — Shree Krishna, Apr 29 '16 at 10:16
@DroidWormNarendra This is `onMeasure`, not `measureScrapChild`.. — Shree Krishna, Apr 29 '16 at 10:21
It belongs to custom LinearLayoutManager class, I already told — Narendra Singh, Apr 29 '16 at 10:43
@ShreeKrishna check my exception log, it will tell, first **onMeasure** will be called, which in turn calls **measureScrapChild** — Narendra Singh, Apr 29 '16 at 10:45
@NarendraJi Did you find the answer for this ? I have the same problem, pl let us know how to solve this. — G murali Madhav, Mar 26 '18 at 08:53

I meet the same problem, and I find a better way to solve it.

call setAutoMeasureEnabled(false); in the constructor of your custom LayoutManager.

After API level 27 setAutoMeasureEnabled() is deprecated. So just override this method in your Custom LinearLayoutManager

@Override
public boolean isAutoMeasureEnabled() {
    return false;
}

After updating RecyclerView from v7:21.0.0 to v7:27.0.2 i faced this issue. By using the proposed solution it finally worked. They must have changed the default beahavior of the RecyclerView from v7:22. Thank you. – GiveEmTheBoot Jan 06 '18 at 21:56

This method has been deprecated since v7:27.1.0. You should override `isAutoMeasureEnabled()` in your implementation. https://developer.android.com/reference/android/support/v7/widget/RecyclerView.LayoutManager.html#setAutoMeasureEnabled(boolean) – Robert Mar 30 '18 at 02:54

Finally resolved :)

Replacing

compile 'com.android.support:recyclerview-v7:23.2.1'

to

compile 'com.android.support:recyclerview-v7:22.+'

worked.

Not Sure, this is perfect solution or not, but it worked for me.

It doesn't work you need to compile with build tools 23. – Oximer Jun 20 '16 at 20:01
