Я получаю эту ошибку на линии -

View view = recycler.getViewForPosition(position); 

Здесь, в этом методе пользовательского 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); 

     } 
    } 

Раньше он работал хорошо. Недавно я изменил targetSdkVersion на 23 (Marshmallow), а также версии поддержки lib. Возможно, проблема по той же причине.

Пожалуйста, помогите мне, как это исправить.

Answer 1

Я встречаю ту же проблему, и я нахожу лучший способ ее решить.

вызов setAutoMeasureEnabled(false); в конструкторе вашего пользовательского LayoutManager.

Answer 2

Наконец решена :)

Замена

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

в

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

работал.

Не уверен, это идеальное решение или нет, но это сработало для меня.
