RecyclerView and IndexOutOfBoundsException: Invalid index #, size is #

问题

I have a simple RecyclerView and I want to remove those items onClick. I was continuously running into a crash depending on when I clicked on certain items in the list with the above error. If you're having similar issues, here's how I solved it:

回答1:

public void onBindViewHolder(final CardViewHolder holder, final int position)

Using position here is useful for some things, but if I used it when removing items from the list, it was causing a crash, instead using:

holder.getAdapterPosition();

resolved my issues immediately.

回答2:

Create a class like this:

public class RecyclerViewNoBugLinearLayoutManager extends LinearLayoutManager {
    public RecyclerViewNoBugLinearLayoutManager(Context context) {
        super( context );
    }

    public RecyclerViewNoBugLinearLayoutManager(Context context, int orientation, boolean reverseLayout) {
        super( context, orientation, reverseLayout );
    }

    public RecyclerViewNoBugLinearLayoutManager(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
        super( context, attrs, defStyleAttr, defStyleRes );
    }

    @Override
    public void onLayoutChildren(RecyclerView.Recycler recycler, RecyclerView.State state) {
        try {
        //try catch一下
            super.onLayoutChildren( recycler, state );
        } catch (IndexOutOfBoundsException e) {
            e.printStackTrace();
        }

    }
}

When you Init the RecylerView add this:

mRecyclerView = (RecyclerView)findViewById(R.id.list_search);
mRecyclerView.setLayoutManager(new FixRecyclerViewManager(mContext));
