Cannot change whether this adapter has stable IDs while the adapter has registered observers

Question

I am using RecyclerView in my android project and its performance has been really awful. From the answers here, I tried adding adapter.setHasStableIds(true); to

Answer 1

as the recyclerView source code:

    /**
     * Indicates whether each item in the data set can be represented with a unique identifier
     * of type {@link java.lang.Long}.
     *
     * @param hasStableIds Whether items in data set have unique identifiers or not.
     * @see #hasStableIds()
     * @see #getItemId(int)
     */
    public void setHasStableIds(boolean hasStableIds) {
        if (hasObservers()) {
            throw new IllegalStateException("Cannot change whether this adapter has "
                    + "stable IDs while the adapter has registered observers.");
        }
        mHasStableIds = hasStableIds;
    } .   

so you can workaround it .

    if (!adapter.hasObservers()) {
        adapter.setHasStableIds(true)
    }
