public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewHolders> { 

private List<ItemObject> itemList; 
private Context context; 


public RecyclerViewAdapter(Context context, List<ItemObject> itemList) { 
    this.itemList = itemList; 
    this.context = context; 
} 

@Override 
public RecyclerViewHolders onCreateViewHolder(ViewGroup parent, int viewType) {

        FragmentManager fm = getFragmentManager(); 

        FragmentTransaction ft = fm.beginTransaction(); 
        ft.replace(R.id.frameLayout, new FragmentNewGame(), "newGame"); 
        ft.addToBackStack(null); 
        ft.commit();

替換此：？？

FragmentManager fm = getFragmentManager(); 

對此：

FragmentManager fm = ((Activity)context).getFragmentManager(); 

然後你的代碼應該看起來像：

FragmentManager fm = ((Activity)context).getFragmentManager(); 
FragmentTransaction ft = fm.beginTransaction(); 
ft.replace(R.id.frameLayout, new FragmentNewGame(), "newGame"); 
ft.addToBackStack(null); 
ft.commit(); 

或者

FragmentTransaction ft = ((Activity)context).getSupportFragmentManager().beginTransaction(); 
ft.replace(R.id.frameLayout, new FragmentNewGame(), "newGame"); 
       ft.addToBackStack(null);
