RecyclerView crashes when “scrapped or attached views may not be recycled”

Question

I\'m using a simple implementation of RecyclerView taken from the Android website using a StaggeredGridLayoutManager and I keep getting this error

Answer 1

this exception is not cause of

android:animateLayoutChanges

or

android:focusableInTouchMode

this final correct answer is just because you set a WRONG LayoutParams.

    nameLP = new LinearLayout.LayoutParams(context.getResources().getDisplayMetrics().widthPixels, LinearLayout.LayoutParams.WRAP_CONTENT);
    nameLP2 = new RecyclerView.LayoutParams(RecyclerView.LayoutParams.MATCH_PARENT, RecyclerView.LayoutParams.WRAP_CONTENT);

the nameLP is OK. the nameLP2 occur the crash .bug is here.

I try all of answers of this page. trust me.
