I try to get a value from json using retrofit like this
holder.txtColor.setText(dataList.get(position).getProductColorMotor().getColorName());
But i got an error like this :
java.lang.String
com.qiscus.qismo.chat.data.model.ordermodel.ProductColorResponse.getColorName()'
on a null object reference
I assume it's because i got null from the JSON response :
...
"product_color_motor": null
...
The response will sometimes return NULL.
But normally the response is look like this :
...
"product_color_motor": {
"id": 315,
"product_variant_id": 9,
"md_model_code": "GW2",
"main_dealer_type": "Beat Pop ESP CW",
"color_id": 86,
"color_code": "PM",
"color_name": "Groovy Red White",
"color_hex_1": "#FFFFFF",
"color_hex_2": "#CC0000",
"parent_color": "Groovy Red White,Groovy,Red,White"
}
...
OrderListResponse.java
public class OrderListResponse {
#SerializedName("product_color_motor")

How can i handle it, if it returns NULL ? Thanks.
Your call getProductColorMotor() can throw an exception. Do the following thing if you want safe Java code:
1) Mark the variable and getter as nullable
#SerializedName("product_color_motor")
#Nullable
private ProductColorResponse productColorMotor;
#Nullable
public ProductColorResponse getProductColorMotor() {
return productColorMotor;
}
2) Don't try to directly access getColorName(), instead, assign the productColorMotor to a variable.
ProductColorResponse p = dataList.get(position)
3) Now check if this is null and provide an alternative text to your txtColor
if (p == null) { holder.txtColor.setText("Alt text") } else { holder.txtColor.setText(p.getColorName())

it should be arrest_warrants[] not String[]
As arrest_warrants is an array of objects you can create arrest_warrant object and in Interpoldetails class, use private List<arrest_warrant> arrest_warrants
How can I use GSON to parse the following JSON object:

The JSON object contains an array of elements. I am using GSON to try and parse the JSON and have the following POJO classes to assist me with this.

The code that I use is the following:
public void onResponse(Call call, Response response) throws IOException
{
String mMessage = response.body().string();
if (response.isSuccessful())
{
try
{
Gson gson = new Gson();
final ProductItems categoryProducts = gson.fromJson(mMessage, ProductItems.class);
response.close();
}
catch (Exception e)
{
Log.e("Error", "Failed to upload");
e.printStackTrace();
}
However, I get the following error: GSON throwing “Expected BEGIN_OBJECT but was BEGIN_ARRAY.
I have tried to change the ProductItems class to taking an object for productbycategories but then I get the following error: com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected a string but was BEGIN_OBJECT at line 1 column 2324 path $.ProductsByCategory[0].meta_data[0].value. I am now a bit confused.
The reason you get this error is that the data is not consistent with the way the POJO is generated.
This is the specific part of the data that has the issue:
"meta_data": [
{
"id": 14232,
"key": "_vc_post_settings",
"value": {
"vc_grid_id": []
}
},
{
"id": 14273,
"key": "fb_product_description",
"value": ""
},
{
"id": 14274,
"key": "fb_visibility",
"value": "1"
},
Notice how the "meta_data" field is an array of objects and that these objects contain a "value" field. The data type of the "value" varies- sometimes it's an object and other times it's a string.
One possible solution would be to change the MetaDatum class so that the value is an Object:
package com.example;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class MetaDatum {
...
#SerializedName("value")

...
public Object getValue() {

How can I count duplicate items : useridfrom and useridto.
I like use from RXJava for better performance an do in background.
I have following JSON string that I need to set to the Java objects of POJO class.
What method should I follow?
{"status":"FOUND","messages":null,"sharedLists": [{"listId":"391647d","listName":"/???","numberOfItems":0,"colla borative":false,"displaySettings":true}] }
I tried using Gson but it did not work for me.
Gson gson = new Gson();
SharedLists target = gson.fromJson(sb.toString(), SharedLists.class);
Following is my SharedLists pojo
public class SharedLists {
#SerializedName("listId")
private String listId;
#SerializedName("listName")
private String listName;
#SerializedName("numberOfItems")
private int numberOfItems;
#SerializedName("collaborative")
private boolean collaborative;
#SerializedName("displaySettings")
private boolean displaySettings;
public int getNumberOfItems() {
return numberOfItems;
}
public void setNumberOfItems(int numberOfItems) {
this.numberOfItems = numberOfItems;
}
public boolean isCollaborative() {
return collaborative;
}
public void setCollaborative(boolean collaborative) {
this.collaborative = collaborative;
}
public boolean isDisplaySettings() {
return displaySettings;
}
public void setDisplaySettings(boolean displaySettings) {
this.displaySettings = displaySettings;
}
public String getListId() {
return listId;
}
public void setListId(String listId) {
this.listId = listId;
}
}
Following is your JSON string.
{
"status": "FOUND",
"messages": null,
"sharedLists": [
{
"listId": "391647d",
"listName": "/???",
"numberOfItems": 0,
"colla borative": false,
"displaySettings": true
}
]
}
Clearly sharedLists is a JSON array within the outer JSON object.
So I have two classes as follows (created from http://www.jsonschema2pojo.org/ by providing your JSON as input)
ResponseObject - Represents the outer object
public class ResponseObject {
#SerializedName("status")
#Expose
private String status;
#SerializedName("messages")
#Expose
private Object messages;
#SerializedName("sharedLists")
#Expose
private List<SharedList> sharedLists = null;
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
public Object getMessages() {
return messages;
}
public void setMessages(Object messages) {
this.messages = messages;
}
public List<SharedList> getSharedLists() {
return sharedLists;
}
public void setSharedLists(List<SharedList> sharedLists) {
this.sharedLists = sharedLists;
}
}
and the SharedList - Represents each object within the array
public class SharedList {
#SerializedName("listId")
#Expose
private String listId;
#SerializedName("listName")
#Expose
private String listName;
#SerializedName("numberOfItems")
#Expose
private Integer numberOfItems;
#SerializedName("colla borative")
#Expose
private Boolean collaBorative;
#SerializedName("displaySettings")
#Expose
private Boolean displaySettings;
public String getListId() {
return listId;
}
public void setListId(String listId) {
this.listId = listId;
}
public String getListName() {
return listName;
}
public void setListName(String listName) {
this.listName = listName;
}
public Integer getNumberOfItems() {
return numberOfItems;
}
public void setNumberOfItems(Integer numberOfItems) {
this.numberOfItems = numberOfItems;
}
public Boolean getCollaBorative() {
return collaBorative;
}
public void setCollaBorative(Boolean collaBorative) {
this.collaBorative = collaBorative;
}
public Boolean getDisplaySettings() {
return displaySettings;
}
public void setDisplaySettings(Boolean displaySettings) {
this.displaySettings = displaySettings;
}
}
Now you can parse the entire JSON string with GSON as follows
Gson gson = new Gson();
ResponseObject target = gson.fromJson(inputString, ResponseObject.class);
Hope this helps.
I have been getting an error with DocumentReferences in a small JSF project i created to learn CouchDB/Ektorp .
I belive everything is working as is should in the CRUD, the id of the parent document is stored as a string, similar to the tutorial project.
But when I retrieve the parent object from the database I get this error:
org.codehaus.jackson.map.JsonMappingException: Can not instantiate value of type

Any help or advice to help me understand what I'm doing wrong will be much appreciated.
Edit: If there is any information that I could add that would make my problem clearer or help in determining the cause of it please let me know.
