报了一个这样的错误 在下面代码引起的,怎么解决? @Override public void onMeasure(RecyclerView.Recycler recycler, RecyclerView.State state, int widthSpec, int heightSpec) { if (measuredHeight <= 0) { View view = recycler.getViewForPosition(0); if (view != null) { measureChild(view, widthSpec, heightSpec); measuredWidth = View.MeasureSpec.getSize(widthSpec); measuredHeight = view.getMeasuredHeight() * getSpanCount(); } } setMeasuredDimension(measuredWidth, measuredHeight); }

我也是报了Invalid item position 0(0) 如何解决？

[syusikoku]

@Override public void onMeasure(RecyclerView.Recycler recycler, RecyclerView.State state, int widthSpec, int heightSpec) { if (measuredHeight <= 0 && state.getItemCount() > 0) { // View view = recycler.getViewForPosition(0); View view = recycler.getViewForPosition(0); if (view != null) { measureChild(view, widthSpec, heightSpec); measuredWidth = View.MeasureSpec.getSize(widthSpec); measuredHeight = view.getMeasuredHeight() * getSpanCount(); } } setMeasuredDimension(measuredWidth, measuredHeight); } 这种方式解决问题

不报错了 但是显示不了东西，只有分页的指示器
