java如何在RecycleView适配器中显示ImageView onClick中的对话框片段

Question

我有ActionBarDialog（DialogFragment）、CarAdapter（RecycleView）和SportFragment。我正在SportFragment中创建方法（infoMethod），以显示DialogFragment并正常工作。但是如果我想在CarAdapter中调用infoMethod，它就不起作用（java.lang.NullPointerException）

SportFragment中的infoMethod

public void infoMethod(){
    Bundle args = new Bundle();
    args.putString("title", "Dialog with Action Bar");
    ActionBarDialog actionbarDialog = new ActionBarDialog();
    actionbarDialog.setArguments(args);
    actionbarDialog.show(getActivity().getSupportFragmentManager(),
            "action_bar_frag");
}

我试图从CarAdapter调用infoMethod

        public MyViewHolder(View view) {
        super(view);

        image= (ImageView) view.findViewById(R.id.imageViewlist);
        image.setOnClickListener(this);

    }
    @Override
    public void onClick(View v) {
        SportFragment infoFrag = new SportFragment();
        if (v.getId() == image.getId()){
            v.startAnimation(AnimationUtils.loadAnimation(v.getContext(), R.anim.imagelist));
            infoFrag.infoMethod(); //call infoMethod not work

            Toast.makeText(v.getContext(), "ITEM PRESSED = " + String.valueOf(getAdapterPosition()), Toast.LENGTH_SHORT).show();
        } else {
            Toast.makeText(v.getContext(), "ROW PRESSED = " + String.valueOf(getAdapterPosition()), Toast.LENGTH_SHORT).show();
        }
    }
