我在我的应用程序中实现了recyclerview,现在我需要从服务器获取数据,我才知道volley是获取数据的最佳方式.我在网上搜索但我无法找到相同的教程.

这是我在我的代码中初始化recyclerview的方法.(具有硬编码数据集)

 mRecyclerView = (RecyclerView) findViewById(R.id.recyclerview);
    LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this);
    linearLayoutManager.setOrientation(LinearLayoutManager.VERTICAL);
    mRecyclerView.setLayoutManager(linearLayoutManager);

    mAdapter = new CardAdapter();
    mRecyclerView.setAdapter(mAdapter);  

这是适配器代码.

public class CardAdapter extends RecyclerView.Adapter<CardAdapter.ViewHolder> {

ArrayList<BusRouteNameDetails> mItems;
public int TAG=0;

public CardAdapter() {
    super();
    mItems = new ArrayList<>();
    BusRouteNameDetails routename = new BusRouteNameDetails();
    routename.setName("xyz");
    routename.setNumber("X4");

    mItems.add(routename);

    routename = new BusRouteNameDetails();
    routename.setName("xyz");
    routename.setNumber("X4");

    mItems.add(routename);

    routename = new BusRouteNameDetails();
    routename.setName("xyz");
    routename.setNumber("X4");

    mItems.add(routename);

    routename = new BusRouteNameDetails();
    routename.setName("xyz");
    routename.setNumber("X4");

    mItems.add(routename);


    routename = new BusRouteNameDetails();
    routename.setName("xyz");
    routename.setNumber("X4");

    mItems.add(routename);
}

@Override
public ViewHolder onCreateViewHolder(ViewGroup viewGroup, …

我似乎是一个重复,但我真的无法找到一个更好的方法来对包含cardview的回收站视图中的数据进行排序.

以下是我的主要活动中的recyclerview片段

 mRecyclerView = (RecyclerView) findViewById(R.id.recyclerview);
    LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this);
    linearLayoutManager.setOrientation(LinearLayoutManager.VERTICAL);
    mRecyclerView.setLayoutManager(linearLayoutManager);


    mAdapter = new PickUpPointAdapter(testData);
    mRecyclerView.setAdapter(mAdapter);
    mCardView=(CardView)findViewById(R.id.searchcard);


    mCardView.setOnClickListener(new View.OnClickListener() {
        @Override public void onClick(View v) {
            // item clicked
            Intent search = new Intent( AppController.getAppContext(), TabLayoutActivity.class);
            search.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            startActivity(search);
        }
    });

    Map<String,String> params = new HashMap<String,String>();
    JsonObjectRequest NearbyPickUpPointReq = new JsonObjectRequest (Request.Method.GET,url_searchNearBybusStopServlet,new JSONObject(params), new Response.Listener<JSONObject>() {
        @Override
        public void onResponse(JSONObject response) {
            Log.d("Tag", response.toString());
            // hidePDialog();
            try {
                JSONArray obj1 = response.getJSONArray("pickuppoint");
                testData.clear();
                // Parsing json
                for (int i …
