I want to display the details(like name,id,plate number etc) in different textviews. But it returns a blank string,ie null.
Here's my API in JSON format
Can someone help me?

Try this interface method.
#GET("user_login_v1")
Call<Obj> getUserDetails(#Query("email") String email,
#Query("password") String password);
and Call method in your MainActivity like this.
Call<Obj> call=login.getUserDetails(email,password);//email and password which user enter when he login in your device.
Feel free to ask more questions.

You can easy to implement in Volley
implementation 'com.android.volley:volley:1.2.0'
In Java Code:
queue = Volley.newRequestQueue(this); // RequestQueue
String url = "https://api.openweathermap.org/data/2.5/find?lat=55.5&lon=37.5&cnt=10&appid=3f8c9db425f5691cb59026f85546237e";
JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, url, null,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
JSONArray jsonArray = response.getJSONArray("list");
for (int i = 0 ; i<jsonArray.length() ; i++){
JSONObject jsonObject = jsonArray.getJSONObject(i);
String id = jsonObject.getString("id");
String name = jsonObject.getString("name");
resultText.append("ID : " + id + "\nName : " + name + "\n\n"); // TextView
}
} catch (JSONException e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
error.printStackTrace();
}}
) ;
queue.add(request);

public void onFailure(Call call, Throwable t) {
Toast.makeText(getApplicationContext(),t.getMessage(),Toast.LENGTH_LONG).show();
}
});
}
}
I don't know what to write in the onResponse() method.

change the for loop.
List<DataItem> items = resObj.getData();
for(int i=0;i<items.size();i++){
Log.e("data",items.get(i).getUserName()); // like this you can access other values in the items list
}

Update api interface method
#GET("user_login_v1")
Call<ResObj> getUserDetails();
Update your getUserData() method
private void getUserData(){
Call<ResObj> call=login.getUserDetails();
call.enqueue(new Callback() {
#Override
public void onResponse(Call call, Response response) {
if(response.isSuccessful()){
ResObj resObj=(ResObj)response.body();
DataItem user=reObj.getData().get(0);
//set value on yout text views
userName.setText(user.getUserName())
userID.setText(user.getUserId())
//....
}
}
#Override
public void onFailure(Call call, Throwable t) {
Toast.makeText(getApplicationContext(),t.getMessage(),Toast.LENGTH_LONG).show();
}
});
}

Create ResObj.class using Android studio plugin "GsonFormat"
It will create a perfect POJO class for your APICall, just past the API GET response from Postman.
It will create a suitable POJO class, from which you can simply call
private void callApi() {
Log.e(TAG, "callApi: inside apiCall");
Call<List> call =
login.getUserDetails();
call.enqueue(new Callback<List>() {
#Override
public void onResponse(Call<List> call, #NonNull Response<List>response) {
List items = response.body();
items = list.data;
String user_id = items.getUserID();
}
#Override
public void onFailure(Call<LiveMatches> call, Throwable t) {
}
call callApi() method where you want to get data;
This method and method will not work if you copy and paste it you need to alter it according to your POJO class but this will provide help
Also add your layout and activity code to give us context

Loop with dataBinding - android

I have two models for get values from service :
First model FieldStudyList.class:
public class FieldStudyList {
#SerializedName("result")
#Expose
private List<ResultFieldStudyList> result = null;
#SerializedName("status")
#Expose
private Integer status;
public List<ResultFieldStudyList> getResult() {
return result;
}
public void setResult(List<ResultFieldStudyList> result) {
this.result = result;
}
public Integer getStatus() {
return status;
}
public void setStatus(Integer status) {
this.status = status;
}
}
Second model ResultFieldStudyList.class:
public class ResultFieldStudyList {
#SerializedName("id")
#Expose
private Integer id;
#SerializedName("introtext")
#Expose
private String introtext;
#SerializedName("title")
#Expose
private String title;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getIntrotext() {
return introtext;
}
public void setIntrotext(String introtext) {
this.introtext = introtext;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
}
I am using from dataBinding in my xml for show values but I can't show them :
<data>
<variable
name="listItems"
type="xxx.xx.models.FieldStudyList" />
</data>
<android.support.v7.widget.CardView
android:id="#+id/card_lstItemStart"
android:layout_width="match_parent"
android:layout_height="wrap_content"
card_view:cardCornerRadius="7dp"
card_view:cardElevation="7dp"
card_view:cardMaxElevation="7dp"
card_view:contentPadding="0dp">
<TextView
android:id="#+id/txtTitle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#{listItems.result.iterator() ???}"<=== I can't show title here ?
android:textSize="20sp" />
</android.support.v7.widget.CardView>

Setting text of multiple TextViews through custom adapter

I'm having trouble setting the text of multiple textviews in a custom list layout with a custom adapter. Here is my list item layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:padding="6dip" >
<ImageView
android:id="#+id/icon"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_alignParentBottom="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="5dip"
android:layout_marginRight="5dp"
android:contentDescription="TODO"
android:src="#drawable/blue_circle" />
<TextView
android:id="#+id/short_content"
android:layout_width="wrap_content"
android:layout_height="26dip"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_toRightOf="#id/icon"
android:ellipsize="marquee"
android:text="content"
android:singleLine="true"
android:textSize="12sp" />
<TextView
android:id="#+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="#id/short_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_alignWithParentIfMissing="true"
android:layout_toRightOf="#id/icon"
android:gravity="center_vertical"
android:text="Title"
android:textSize="16sp" />
<TextView
android:id="#+id/date"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_above="#id/short_content"
android:layout_alignParentTop="true"
android:layout_toRightOf="#id/icon"
android:gravity="right"
android:text="date"
android:textSize="13sp" />
Here is my adapter:
public class MessageAdapter extends ArrayAdapter<TextContent> {
public MessageAdapter(Context context, int textViewResourceId){
super(context, textViewResourceId);
}
public MessageAdapter(Context context, int textViewResourceId, List<TextContent> items){
super(context, textViewResourceId, items);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = convertView;
if (view == null) {
LayoutInflater inflater;
inflater = LayoutInflater.from(getContext());
view = inflater.inflate(R.layout.messages_layout, null);
}
TextContent p = getItem(position);
if(p != null) {
TextView textViewShortContent = (TextView) view.findViewById(R.id.short_content);
TextView textViewTitle = (TextView) view.findViewById(R.id.title);
TextView textViewDate = (TextView) view.findViewById(R.id.date);
if (textViewShortContent != null) {
textViewShortContent.setText("Short Content");
}
if (textViewTitle != null) {
textViewTitle.setText("TITLE");
}
if (textViewDate != null) {
textViewDate.setText("DATE");
}
}
return view;
}
}
here is my textContent class:
public class TextContent implements Serializable{
private String GUID, created, modified, deleted, name, message, title, shortContent, fullContent, author, language, person;
public TextContent(){
}
public TextContent(String GUID, String created, String modified, String deleted, String name, String message, String title,
String shortContent, String fullContent, String author, String language, String person) {
this.GUID = GUID;
this.created = created;
this.modified = modified;
this.deleted = deleted;
this.name = name;
this.message = message;
this.title = title;
this.shortContent = shortContent;
this.fullContent = fullContent;
this.author = author;
this.language = language;
this.person = person;
}
public String getGUID() {
return GUID;
}
public String getCreated() {
return created;
}
public String getModified() {
return modified;
}
public String getDeleted() {
return deleted;
}
public String getName() {
return name;
}
public String getMessage() {
return message;
}
public String getTitle() {
return title;
}
public String getShortContent() {
return shortContent;
}
public String getFullContent() {
return fullContent;
}
public String getAuthor() {
return author;
}
public String getLanguage() {
return language;
}
public String getPerson() {
return person;
}
public void setGUID(String GUID) {
this.GUID = GUID;
}
public void setCreated(String created) {
this.created = created;
}
public void setModified(String modified) {
this.modified = modified;
}
public void setDeleted(String deleted) {
this.deleted = deleted;
}
public void setName(String name) {
this.name = name;
}
public void setMessage(String message) {
this.message = message;
}
public void setTitle(String title) {
this.title = title;
}
public void setShortContent(String shortContent) {
this.shortContent = shortContent;
}
public void setFullContent(String fullContent) {
this.fullContent = fullContent;
}
public void setAuthor(String author) {
this.author = author;
}
public void setLanguage(String language) {
this.language = language;
}
public void setPerson(String person) {
this.person = person;
}
}
and here is where I instantiate my adapter
listView = (ListView) getView().findViewById(R.id.list_view_messages);
MessageAdapter adapter = new MessageAdapter(context, R.layout.messages_layout, textContentList);
listView.setAdapter(adapter);
The only thing that gets displayed is the getShortContent but not getTitle or getCreated for some reason. I am 100% certain that text has been set for all fields of the textContent.

I figured it out. The textViews in my layout was overlapping so the content from the other textviews got hidden behind.
