、私のPOJOクラスが好きです：
私のAPIのURLは、このURLのような応答を返すhttps://www.paidup.io/api/v1/businesses/212/menu
ある
package ph.paidup.models;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
/**
* Created by oxiloindia on 3/30/2016.
*/
public class Item {
@SerializedName("title")
@Expose
private String title;
@SerializedName("size")
@Expose
private Object size;
@SerializedName("price")
@Expose
private Integer price;
/**
*

*/
public String getTitle() {
return title;
}
/**
*
* @param title

*/
public void setTitle(String title) {
this.title = title;
}
/**

*/
public Object getSize() {
return size;
}
/**

public void setSize(Object size) {
this.size = size;

/**

public Integer getPrice() {
return price;
}
/**

public void setPrice(Integer price) {
this.price = price;
}
}
と別のクラス：今
package ph.paidup.models;
import java.util.ArrayList;
import java.util.List;
import javax.annotation.Generated;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
/**

@Generated("org.jsonschema2pojo")
public class MenuRequest {
@SerializedName("category")
@Expose
private String category;
@SerializedName("items")
@Expose
private List<Item> items = new ArrayList<Item>();
/**
*
* @return

*/
public String getCategory() {
return category;
}
/**
*
* @param category
* The category
*/
public void setCategory(String category) {
this.category = category;
}
/**

*/
public List<Item> getItems() {
return items;
}
/**

*/
public void setItems(List<Item> items) {
this.items = items;
}
}
私はを得るために私の活動でこれを解析したい は 「カテゴリ」によると、recyclerviewにその
「タイトル」と 「価格」が必要私はこの方法のようにそれを実行しようとしてい
：私は解析するすべての要求を試してみました
public void getInVoice() {
showProgress(true);
String URL="https://www.paidup.io/api/v1/businesses/212/menu";
JsonArrayRequest req = new JsonArrayRequest(Request.Method.GET,URL,null, new Response.Listener<JSONArray>() {
@Override
public void onResponse(JSONArray response) {
showProgress(false);
VolleyLog.v("Response:%n %s", response);
Gson gson = new GsonBuilder().create();
for (int i = 0; i < response.length(); i++) {
try {
JSONObject jsonObject = new JSONObject();
String desc = jsonObject.getString("category");
JsonParser jsonParser = new JsonParser();
groupItem.items = (List<Item>) jsonParser.parse(String.valueOf(response));
// Create a new adapter with data items
mExpandableAdapter = new BakeryMenuExpandableAdapter(getActivity(), setUpList(groupItem.items)) {
@Override
public void onItemClick(int position, View v) {
}
};
// Attach this activity to the Adapter as the ExpandCollapseListener
mExpandableAdapter.setExpandCollapseListener(new ExpandableRecyclerAdapter.ExpandCollapseListener() {
@Override
public void onListItemExpanded(int position) {
Log.e("CHEEE", "" + position);
}
@Override
public void onListItemCollapsed(int position) {
}
});
// Set the RecyclerView's adapter to the ExpandableAdapter we just created
recyclerView.setAdapter(mExpandableAdapter);
// Set the layout manager to a LinearLayout manager for vertical list
recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
} catch (Exception e) {
Log.e("My App", "Could not parse malformed JSON: \"" + response + "\"");
e.printStackTrace();
}
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Activity activity = getActivity();
if (activity != null && isAdded())
showProgress(false);
Toast.makeText(getActivity(), "Something went wrong. please try it again", Toast.LENGTH_SHORT).show();
}
});
// add the request object to the queue to be executed
addToRequestQueue(req, TAG);
}
成功することはできませんでした。
iは、事前にrecyclerviewのためのアイテムの
おかげでリストを取得するために、tryブロックで行うには何が必要なはずです.... plzは解決それ
