@Override
public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
super.onScrollStateChanged(recyclerView, newState);
final RecyclerView.LayoutManager layoutManager = recyclerView.getLayoutManager();
if(!(layoutManager instanceof CustomLayoutManager)){
mAutoSet = true;
return;
}
if(!mAutoSet){
if(newState == RecyclerView.SCROLL_STATE_IDLE){
final int dx;
dx = ((CustomLayoutManager)layoutManager).getOffsetCenterView();
//Log.e(TAG, "getOffsetCenterView: " + String.valueOf(dx));
recyclerView.smoothScrollBy(dx,0);
}
