将项目从Android recyclerview共享到Facebook

问题描述

我们如何将Android recyclerview中的项目共享到Facebook？我想分享一个项目，就像在Facebook上一样。并且，当用户单击Facebook帖子时，如果该应用程序安装在用户的移动设备上，那么他将被定向到android应用程序中的原始项目。这是recyclerview适配器的代码。

    public class QuestionAdapter extends RecyclerView.Adapter<QuestionAdapter.QuestionViewHolder> {

    Context mContext;
    List<QuestionModel> mData;
    public QuestionAdapter(MainActivity mainActivity,List<QuestionModel> mData) {
        this.mData = mData;
        mContext = mainActivity.getApplicationContext();
    }

    @NonNull
    @Override
    public QuestionAdapter.QuestionViewHolder onCreateViewHolder(@NonNull ViewGroup parent,int viewType) {

        View layout;
        layout = LayoutInflater.from(mContext).inflate(R.layout.item_question,parent,false);

        return new QuestionViewHolder(layout);
    }

    @Override
    public void onBindViewHolder(@NonNull QuestionAdapter.QuestionViewHolder holder,int position) {

        QuestionModel question = mData.get(position);
        holder.txtStatement.setText(position + 1 + ". " + question.getStatement());
        holder.txtA.setText("a) " + question.getA());
        holder.txtB.setText("b) " + question.getB());
        holder.txtC.setText("c) " + question.getC());
        holder.txtD.setText("d) " + question.getD());
        holder.txtAnswer.setText("Answer: " + question.getAnswer());
    }

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

    public class QuestionViewHolder extends RecyclerView.ViewHolder {

        TextView txtStatement;
        TextView txtA;
        TextView txtB;
        TextView txtC;
        TextView txtD;
        TextView txtAnswer;

        public QuestionViewHolder(@NonNull View itemView) {
            super(itemView);
            txtStatement = itemView.findViewById(R.id.txt_Statement);
            txtA = itemView.findViewById(R.id.txt_A);
            txtB = itemView.findViewById(R.id.txt_B);
            txtC = itemView.findViewById(R.id.txt_C);
            txtD = itemView.findViewById(R.id.txt_D);
            txtAnswer = itemView.findViewById(R.id.txt_Answer);

        }
    }
}

以下是recyclerview中某个项目的代码。
