Question

当我点击recyclerview的单行时，我想从recyclerview适配器打开片段。我在此活动中有一个主要活动和三个片段与视图寻呼机。在第二个片段里面我还有两个片段。在第一个片段里面我使用了recyclerview。从那个recyclerview我想在点击recyclelerview行时打开新的片段。

    ProfileActivity3 profileActivity3 = (ProfileActivity3) context;

    public TodayTaskAdapter(Activity context, ArrayList<TaskPayload> taskPayloadArrayList)

    }


    @Override

                transaction.replace(R.id.frame_container, fragmentTaskHistory, "Fragment History Task").commit();

            }
        });

    }

    @Override
    public int getItemCount() {
        return taskPayloadArrayList.size();
    }

    public static class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {


        TextView tvTitle,tvDesc,tvAssignDate,tvDeadline;

        private ItemClickListener clickListener;


        public MyViewHolder(View itemView) {

            itemView.setOnClickListener(this);

        }

        public void setClickListener(ItemClickListener itemClickListener){
            this.clickListener = itemClickListener;
        }

        @Override
        public void onClick(View view) {
            clickListener.onClick(view,getPosition(),false);

        }


    }
}

试试这种方式;

holder.setClickListener(new ItemClickListener() {
        @Override
        public void onClick(View view, int position, boolean isLongClick) {

             Fragment fragment = new FragmentTaskHistory();
             FragmentManager fm = getActivity().getSupportFragmentManager();
             FragmentTransaction ft = fm.beginTransaction();
             ft.replace(R.id.frame_container, fragment);
             ft.commit();

        }
    });
