Question

我试图设置一个可点击的cardview，这样当点击列表中的卡片时，片段会在我的recyclerview中展开。到目前为止，我可以点击注册并显示位置，如果我敬酒，但当我尝试在fragment_container中膨胀新视图时，我一直收到错误。

下面显示的代码抛出“错误：（49,54）错误：非静态方法getFragmentManager（）无法从静态上下文引用”

有人可以告诉我如何解决此错误吗？

public abstract class MyPageHolder extends RecyclerView.ViewHolder{

    protected Activity activity;
    protected MyPageAdapter adapter;
    public TextView txtTitle, txtDescription;
    public ImageView imgImage;
    public View view;


    public MyPageHolder(final View v, final Activity activity, MyPageAdapter adapter) {
        super(v);
        this.activity = activity;
        this.adapter = adapter;

        imgImage = (ImageView) v.findViewById(R.id.cardview_image);
        txtTitle = (TextView) v.findViewById(R.id.cardview_title);
        txtDescription = (TextView) v.findViewById(R.id.cardview_description);
        view = (CardView) v.findViewById(R.id.card_view);

        view = itemView;

        view.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                //what to put here

                FragmentManager fm = FragmentActivity.getFragmentManager();
                FragmentTransaction ft = fm.beginTransaction();
                ft.replace(R.id.fragment_container, new WhatIWantToDisplayFragment(), "fragment_screen");
                ft.commit();
                break;




            }
        });
    }


    public void bind(ListItems dataModel, Activity activity, int position) {
        ListItems m = (ListItems)dataModel;
        imgImage.setImageResource(m.image);
        txtTitle.setText(m.title);
        txtDescription.setText(m.description);
    }


}

您不能像那样创建FragmentManager个实例 FragmentManager fm = FragmentActivity.getFragmentManager();，

而是使用活动实例来创建一个 FragmentManager fm = activity.getFragmentManager();

试图设置onClick for Recyclerview
