Java 片段活动上的ListViewAdapter上下文错误，我应该怎么做？

安卓大师晚安。请帮帮我。也许你们中比我更了解的人可以帮助我解决我现在面临的问题

我在片段上做了一个列表视图。我停了下来，因为我不知道该怎么做。也许下面的代码可以帮助你解决我的问题

这是我做的碎片。我把它命名为Frag_Tour.java

public class Frag_Tour extends Fragment {

    ListView listView;
    ListViewAdapterTour adapter;
    String[] judul1;
    String[] judul2;
    String[] durasi;
    String[] harga;
    int[] gambarTour;
    ArrayList<Model> arrayList = new ArrayList<Model>();

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

        View rootView = inflater.inflate(R.layout.frag_tour, container, false);

        judul1 = new String[]{"Paket Hemat", "Paket Reguler", "Paket Honeymoon"};
        judul2 = new String[]{"Wisata Belitung", "Wisata Belitung", "Wisata Belitung"};
        durasi = new String[]{"3 Hari 2 Malam", "4 Hari 3 Malam", "3 Hari 1 Malam"};
        harga = new String[]{"Rp 750.000/pax", "Rp 750.000/pax", "Rp 750.000/pax"};
        gambarTour = new int[]{
                R.drawable.mercusuar_1, R.drawable.mercusuar_2, R.drawable.mercusuar_3
        };

        listView = rootView.findViewById(R.id.listView);

        for (int i = 0; i < judul1.length; i++) {
            Model model = new Model(judul1[i], judul2[i], durasi[i], harga[i], gambarTour[i]);
            arrayList.add(model);
        }

        adapter = new ListViewAdapterTour(this, arrayList);

        listView.setAdapter((ListAdapter) arrayList);

        return rootView;
    }

}

我希望安卓的老师和大师们能帮助我解决这个问题。我想要的是row_tour.xml，我将它设计为frag_tour.xml中的listview

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/parent_view"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ListView
        android:id="@+id/listView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

</LinearLayout>

[4] 上下文应该是包含片段的活动。因此，在适配器构造函数中使用

getActivity（）

---

您应该创建一个类，然后创建该类的列表，而不是多个字符串数组。listView.setAdapter（（ListAdapter）arrayList）；很好的类强制转换异常。。ListViewAdapterTour（此，arrayList）。。这是一个片段，构造函数通常希望ContextTry在出现错误的地方使用

getActivity（）

而不是

this

。非常感谢，这非常有用。我的代码没有更多的错误。但是不能跑。我不知道哪一部分是错误的。我只想向活动片段添加一个listview。我在网上搜索了一下，但是没有人能找到。

public class ListViewAdapterTour extends BaseAdapter {


    Context mContext;
    LayoutInflater inflater;
    List<Model> modellist;
    ArrayList<Model> arrayList;

    public ListViewAdapterTour (Context context, List<Model> modellist) {

        mContext = context;
        this.modellist = modellist;
        inflater = LayoutInflater.from(mContext);
        this.arrayList = new ArrayList<Model>();
        this.arrayList.addAll(modellist);

        }
        else {

        holder.GambarTour.setImageResource(modellist.get(position).getGambartour());

        view.setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {
                if (modellist.get(position).getJudul1().equals("Paket Hemat 3 Hari 2 Malam")){
                    Intent intent = new Intent(mContext, TourDetail.class);
                    intent.putExtra("contentTv","PAKET HEMAT");
                    mContext.startActivity(intent);
                }
            }
        });

        return view;
    }
}
