How to parse an xml to java class with recycler view or in adapter of recyclerview

问题

I have an xml file which name it is Bookmark and it is into the xml folder. I want to parse xml to recycler view which I can show the list of the Bookmark in recycler view. The bookmark xml it is not in assets it is in res then xml folder. This is my code.

Bookmark.xml in the xml folder

<Bookmarks>
    <Bookmark id="1" icon="google.png" name="Google" searchUrl="https://www.google.com" hidden="true" />
    <Bookmark id="2" icon="youtube_new.png" name="Youtube" searchUrl="http://m.youtube.com" />
    <Bookmark id="3" icon="facebook.png" name="Facebook" nativeUrl="facebook://" searchUrl="https://m.facebook.com" />
    <Bookmark id="4" icon="twitter.png" name="Twitter" searchUrl="https://mobile.twitte.com" />
    <Bookmark id="5" icon="instagram.png" name="Instagram" nativeUrl="instagram://" searchUrl="https:instagram.com" />
    <Bookmark id="6" icon="gmail.png" name="Gmail" nativeUrl="googlemail://" searchUrl="https://gmail.com" />
    <Bookmark id="7" icon="google_translate.png" name="Translate" searchUrl="https://" />

</Bookmarks>

This is the java class for recycler view

 public class FragmentBookmark extends Fragment {
    ArrayList<Bookmark> arrayList = new ArrayList<>();
    XmlPullParserFactory pullParserFactory;
    RecyclerView myRecyclerView;
    MyAdapter myAdapter;

    public void onCreateView(@Nullable Bundle savedInstanceState) {
        myRecyclerView = getActivity().findViewById(R.id.myRecyclerView);
        RecyclerView.LayoutManager layoutManager = new GridLayoutManager(getActivity(), 1);
        myRecyclerView.setHasFixedSize(true);
        try {
            pullParserFactory = XmlPullParserFactory.newInstance();
            XmlPullParser parser = pullParserFactory.newPullParser();

            InputStream in_s = getActivity().getApplicationContext().getAssets().open("bookmarks.xml");
            parser.setFeature(XmlPullParser.FEATURE_PROCESS_NAMESPACES, false);
            parser.setInput(in_s, null);

            parseXML(parser);

        } catch (XmlPullParserException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        for (int i = 0; i < arrayList.size(); i++) {
            Log.e("OUTPUT", arrayList.get(i).toString());
        }

        myAdapter = new MyAdapter(getActivity(), arrayList);
        myRecyclerView.setAdapter(myAdapter);
    }

    private void parseXML(XmlPullParser parser) throws XmlPullParserException, IOException {
        ArrayList<Bookmark> countries = null;
        int eventType = parser.getEventType();
        Bookmark country = null;

        while (eventType != XmlPullParser.END_DOCUMENT) {
            String name;
            name = parser.getName();
            switch (eventType) {
                case XmlPullParser.START_DOCUMENT:
                    countries = new ArrayList();
                    break;
                case XmlPullParser.START_TAG:
                    break;

                case XmlPullParser.END_TAG:
                    if (name.equals("Bookmark")) {

                        Bookmark bookmark = new Bookmark();
                        bookmark.setName(parser.getAttributeValue(null, "name"));
                        bookmark.setIcon(parser.getAttributeValue(null, "icon"));
                        bookmark.setId(parser.getAttributeValue(null, "id"));
                        bookmark.setSearchUrl(parser.getAttributeValue(null, "searchUrl"));
                        bookmark.setNativeUrl(parser.getAttributeValue(null, "nativeUrl"));
                        arrayList.add(bookmark);
                    }
                    break;
            }
            eventType = parser.next();
        }


    }

    private void processParsing(XmlPullParser parser) throws IOException, XmlPullParserException {
        int eventType = parser.getEventType();
        Bookmark bookmark = null;


    }
    }

This is the recycler view xml

<android.support.v7.widget.RecyclerView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/listRecyclerView"
    android:layout_height="match_parent"
    android:orientation="horizontal"
    android:layout_width="match_parent"
    android:layout_marginBottom="8dp"
    android:layout_marginEnd="8dp"
    android:layout_marginStart="8dp"
    android:layout_marginTop="8dp"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    android:fillViewport="false">

    </android.support.v7.widget.RecyclerView>

This is the adapter for recyclerview

public class MyAdapter extends RecyclerView.Adapter {
    @NonNull
    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
        View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.grid_item, viewGroup, false);
        return new ListViewHolder(view);
    }

    @Override
    public void onBindViewHolder(@NonNull RecyclerView.ViewHolder viewHolder, int i) {
        ((ListViewHolder) viewHolder).bindView(i);
    }

    @Override
    public int getItemCount() {
        return OurData.title.length;
    }

    private class ListViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
        private TextView mItemText;
        private ImageView mItemImage;

        public ListViewHolder(View itemView) {
            super(itemView);
            mItemText = itemView.findViewById(R.id.textView);
            mItemImage =  itemView.findViewById(R.id.image_view);
            itemView.setOnClickListener(this);
        }

        public void bindView(int position) {
            mItemText.setText(OurData.title[position]);
            mItemImage.setImageResource(OurData.picture[position]);

        }

        @Override
        public void onClick(View v) {

        }
    }
}

This is a java class which I have added manually and works in the recycler view but I need the Bookmark xml to show in recycler view

public class OurData {
    public static String[] title = new String[] {
            "Bing",
            "Facebook",
            "Gmail",
            "Translate",
            "Bing",
            "Facebook",
            "Gmail",
            "Translate"
    };

    public static int[] picture = new int[] {
            R.drawable.instagram,
            R.drawable.instagram,
            R.drawable.instagram,
            R.drawable.instagram,
            R.drawable.instagram,
            R.drawable.instagram,
            R.drawable.instagram,
            R.drawable.instagram

    };
}

This is the xml to show an Image and a TextView for recycler view

<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

    <ImageView
        android:id="@+id/image_view"
        android:layout_width="28dp"
        android:layout_height="27dp"
        android:layout_alignParentTop="true"
        android:layout_marginStart="8dp"
        android:layout_marginEnd="8dp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHorizontal_bias="0.129"
        app:layout_constraintStart_toStartOf="parent"

        android:layout_marginStart="8dp"
        android:layout_marginEnd="8dp"

Here is the code to parse XML from res/XML folder

    try {

        XmlPullParser xpp = getResources().getXml(R.xml.bookmarks);

        while (xpp.getEventType() != XmlPullParser.END_DOCUMENT) {
            if (xpp.getEventType() == XmlPullParser.START_TAG) {
                if (xpp.getName().equals("Bookmark")) {

                    Log.e("MY_VALUE", " * " + xpp.getAttributeValue(0) + " * ");
                    Log.e("MY_VALUE", " * " + xpp.getAttributeValue(1) + " * ");
                    Log.e("MY_VALUE", " * " + xpp.getAttributeValue(5) + " * ");
                    Log.e("MY_VALUE", " * " + xpp.getAttributeValue(2) + " * ");
                    Log.e("MY_VALUE", " * " + xpp.getAttributeValue(3) + " * ");
                    Log.e("MY_VALUE", " * " + xpp.getAttributeValue(4) + " * ");

                    Bookmark bookmark = new Bookmark();
                    bookmark.setName(xpp.getAttributeValue(0));
                    bookmark.setIcon(xpp.getAttributeValue(1));
                    bookmark.setId(xpp.getAttributeValue(2));
                    bookmark.setSearchUrl(xpp.getAttributeValue(3));
                    bookmark.setNativeUrl(xpp.getAttributeValue(4));
                    arrayList.add(bookmark);

                }
            }

            xpp.next();
        }
    } catch (XmlPullParserException e) {
        e.printStackTrace();
    } catch (IOException e) {

There are three types of android XML parser that we can use.

• SAX Parsers

• DOM Parsers

• XMLPullParser

You can use XmlPullParserFactory to parse your xml

Try this here is the working code

        try {

            XmlPullParser parser = pullParserFactory.newPullParser();

            InputStream in_s = getApplicationContext().getAssets().open("bookmark.xml");
            parser.setFeature(XmlPullParser.FEATURE_PROCESS_NAMESPACES, false);
            parser.setInput(in_s, null);

            parseXML(parser);
