响应生命周期Lifecycle的自定义RecyclerView

BaseRecyclerView.java

public class BaseRecyclerView extends RecyclerView implements LifecycleObserver {
    public BaseRecyclerView(@NonNull Context context) {
        super(context);
        init(context);
    }

        init(context);
    }

    public BaseRecyclerView(@NonNull Context context, @Nullable AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        init(context);
    }

    private void init(Context context) {
        if (context instanceof LifecycleOwner) {
            ((LifecycleOwner) context).getLifecycle().addObserver(this);
        }
    }

    @OnLifecycleEvent(Lifecycle.Event.ON_DESTROY)
    public void onDestory() {
        /*
         确保Adapter#onDetachedFromRecyclerView被调用
         */
        setAdapter(null);
    }

    @Override
    public void setLayoutManager(LayoutManager layoutManager) {
        super.setLayoutManager(layoutManager);
        if (layoutManager instanceof LinearLayoutManager) {
            /*
            确保Adapter#onViewDetachedFromWindow被调用
             */
            ((LinearLayoutManager) layoutManager).setRecycleChildrenOnDetach(true);
