RecyclerView: java.lang.IndexOutOfBoundsException: Inconsistency detected. Invalid item position

问题:

I've started getting this crash reported on Crashlytics. I have no idea how to reproduce it but it all appears to be code internal to the RecyclerView. I think this comes from a RecyclerView I have which never really changes. The user can refresh it but then all items are replaced and notifyDataSetChanged is called.

I have same issue with this problem, I'm very tired to search and resolve it. But I have found answer to resolve and exceptions have not been thrown out again.

public class MyLinearLayoutManager extends LinearLayoutManager  {     public MyLinearLayoutManager(Context context) {         super(context);     }      public MyLinearLayoutManager(Context context, int orientation, boolean reverseLayout) {         super(context, orientation, reverseLayout);     }      public MyLinearLayoutManager(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {         super(context, attrs, defStyleAttr, defStyleRes);     }      @Override     public boolean supportsPredictiveItemAnimations() {         return false;     }      @Override     public void onLayoutChildren(RecyclerView.Recycler recycler, RecyclerView.State state) {         //override this method and implement code as below         try {             super.onLayoutChildren(recycler, state);         } catch (Exception e) {             e.printStackTrace();         }     } } 

I hope this answer will be resolve your problem.

回答2:

Create your own LinearLayoutManager.

CustomLinearLayoutManager.java

public class CustomLinearLayoutManager extends LinearLayoutManager {      @Override     public boolean supportsPredictiveItemAnimations() {         return false;     }      public CustomLinearLayoutManager(Context context) {         super(context);     }      public CustomLinearLayoutManager(Context context, int orientation, boolean reverseLayout) {         super(context, orientation, reverseLayout);     }      public CustomLinearLayoutManager(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {         super(context, attrs, defStyleAttr, defStyleRes);     } } 

How to set CustomLinearLayoutManager on RecyclerView.

CustomLinearLayoutManager customLinearLayoutManager= new HPLinearLayoutManager(mContext); recyclerView.setLayoutManager(customLinearLayoutManager); 

Hope this will save your time.
