So am working with retrofit and rxjava for my application.so am using the #GET annociation to pull my blog details from the server that include blog_title, blog_content, blog_thumbnail etc and all this parameter are within an array called blog_post.
I have my APIClient:
public class ApiClient {
private static final String STAGING_BASE_URL = "https://watchnollywood.ml/api/";
private static ApiClient instance;
private ApiService apiService;
private ApiClient(){
HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
// set your desired log level
// TODO: 21/03/2017 when going live change the log level to NONE, to enhance performance
logging.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
// add logging as last interceptor
httpClient.addInterceptor(logging); // <-- this is the important line for logging requests!
final Gson gson = new GsonBuilder().setFieldNamingPolicy(FieldNamingPolicy.LOWER_CASE_WITH_UNDERSCORES).create();
//final Retrofit retrofit = new Retrofit.Builder().baseUrl(STAGING_BASE_URL).addCallAdapterFactory(RxJavaCallAdapterFactory.create()).addConverterFactory(GsonConverterFactory.create(gson)).client(httpClient.build()).build();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(STAGING_BASE_URL)
.client(httpClient.build())
.addConverterFactory(GsonConverterFactory.create())
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.build();
apiService = retrofit.create(ApiService.class);
}
public static ApiClient getInstance(){
if(instance == null){
instance = new ApiClient();
}
return instance;
}
//API CALL FOR LOGIN
public Observable<UserItem> login(String email, String password){
return apiService.signIn(email,password);
}
//API CALL FOR SIGNUP
public Observable<StatusItem> signup(String email, String password, String full_name, String phone){
return apiService.signUp(email, password,phone,full_name);
}
//API CALL FOR BLOG DETAILS
public Observable<BlogResponse> blog_post(){
return apiService.blog_post();
}
}
ApiService:
public interface ApiService {
#FormUrlEncoded
#POST("signin")
Observable<UserItem> signIn(#Field("email") String email, #Field("password") String password);
#FormUrlEncoded
#POST("signup")
Observable<StatusItem> signUp(#Field("full_name")String full_name, #Field("phone") String phone, #Field("email") String email, #Field("password") String password);
#GET("blog")
Observable<BlogResponse> blog_post();
}
pojo classes:
public class BlogItem {
private int thumbNail;
private String title;
private String summary;
public int getThumbNail() {
return thumbNail;
}
public void setThumbNail(#DrawableRes int thumbNail) {
this.thumbNail = thumbNail;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getSummary() {
return summary;
}
public void setSummary(String summary) {
this.summary = summary;
}
}
public class BlogResponse {
private BlogItem[] blogItems;
public BlogItem[] getBlogItems() {
return blogItems;
}
public void setBlogItems(BlogItem[] blogItems) {
this.blogItems = blogItems;
}
}
I have a recyclerview that will hold all the information that will be coming from the server. But the problem is that when I run it I get a log response in my RUN terminal but nothing is showing on the app screen.
this is my FragmentClass that holds the information from the server:
BlogFragment:

What am I not doing right. Someone Please Help!!!
In the private void BlogPost() { method, you create BlogItems but then don't do anything with it. You probably forgot to add them to the blogItems list.
In addition, the call to adapter.notifyItemRangeChanged in that method happens way before the sequence receives data but you don't call that after each blogItem or when all blog items have arrived - the observer is on a complete different execution path than the outer BlogPost() method.
Edit spelled out:
#Override
public void onNext(BlogResponse value) {
for (BlogItem responseItem : value.getBlogItems()) {
BlogItem blogItem = new BlogItem();
blogItem.setTitle(responseItem.getTitle().toString());
blogItem.setSummary(responseItem.getSummary().toString());
blogItems.add(blogItem);
}
adapter.notifyItemRangeChanged(0, adapter.getItemCount());
}
#Override
public void onError(Throwable e) {
}
#Override
public void onComplete() {
BlogItem blogItem = new BlogItem();
blogItem.setTitle("blog_title");
blogItem.setSummary("blog_content");
blogItems.add(blogItem);
adapter.notifyItemRangeChanged(0, adapter.getItemCount());
}

I'm having a problem retrieving the payments data. It always says I can't convert object type to:

My Firebase database structured:

When you are passing your paymentsRef to the FirebaseRecyclerOptions<Payments> object it means that you are looking for Payments objects but within your reference, there are only objects of type String and not Payments, and that's why you get that error. To solve this, simply remove the call to .child("Payments"):
paymentsRef = FirebaseDatabase.getInstance().getReference()
.child("Cart List").child("Admin View").child(userID);
And you'll be able to get all Payments objects that exist within your userID node.
I want to fetch the array list of users. I have three POGO classes i.e Root(Parent class), ContactFamilyDetails(Child class), DataModelFamilyDetails(GrandChild class).
The problem that I have faced all the time that when I run the application at that time I only get the first array value, unfortunately, I didn't get the rest of the values. So I am going to share my whole code so please go through it and help me out of it !! Thank You!!

Try to add your string at the end of your class or remove all the parcelable generated code, add your string, then apply again the parcelable implementation.
This happens because you're not updating the parcel methods.
I’ve been trying to get recycler view working with retrofit. I seem to be pulling in the JSON fine from within getRecipes() method, and my logs are showing me that the some data is there.
However, when I call my getRecipes() method from onCreate(), something seems to be going wrong. When I check to see if my recipeList array contains my JSON results within onCreate, it is telling me it is empty. Why is it doing this if my logs within my getRecipes() method are showing me that data is there...?
Not sure if it is an issue with my recycler view or what I am doing with retrofit, or something else. Been trying for days to figure out, so any advice would be greatly appreciated.

this will be empty always because this line will execute before getting the response from a server.
if(recipeList.isEmpty()){
Log.d(LOG_TAG, "Is empty");
}else {
Log.d(LOG_TAG, "Is not empty");
}
Better call this after this line recipeList = response.body();
SimpleItemRecyclerViewAdapter simpleItemRecyclerViewAdapter = new SimpleItemRecyclerViewAdapter(recipeList);
recyclerView.setAdapter(simpleItemRecyclerViewAdapter);
if (findViewById(R.id.item_detail_container) != null) {
mTwoPane = true;
}
it is because you are sending the recipelist into the adapter before even it is populated , after you are sending the recipelist into the adapter which is empty you are populating your recipelist from getRecipes method, you might be wondering you have declared the getRecipes method before even you are assigning the recipelist to adapter so how come it is empty, yea but the fact is your getRecipes work on background thread so even before your recipelist gets populated your adapter assignment takes place on the main thread so you are basically assigning the empty list, one thing you can do is notify when the adapter when the data changes or when the the recipelist is filled with data that is from within the getRecipe method.
when you assign the recipelist = response.body right after this you can notify the adapter
or move this two lines
SimpleItemRecyclerViewAdapter simpleItemRecyclerViewAdapter = new SimpleItemRecyclerViewAdapter(recipeList);
recyclerView.setAdapter(simpleItemRecyclerViewAdapter);
right after the
recipelist = response.body;
in getRecipes method
Try create the Constructor with all atributes from your Recipe.class
Like:
public Ingredients(String measure, String ingredients, String quantity ){
this.measure = measure;
this.ingredients = ingredients;
this.quantity = quantity
}
Do same in all class where make up your object of list.
Im having an issue with getting data that is obtained when my listadapter is set to my listview. Im trying to get this data in onItemClick so that i can put it into my intent extra's for my other activity to obtain.
The Problem
Currently i've created null string variables and then in my adapter assigning the strings with the desired text by methods within my model. However the problem im having is that the text that is being pulled is not the correct text for the position that onitemclick was called for.
Here some code...
XMLParseActivity
public class XMLParseActivity extends Activity implements AdapterView.OnItemClickListener {
private ListView mIssueListView;
private IssueParser mIssueParser;
private List<IssueFeed> mIssueList;
private IssueAdapter mIssueAdapter;
private String result_connectedtype = "";
private String result_symptom = "";
private String result_problem = "";
private String result_solution = "";
private String result_comments = "";
...
public class IssueAdapter extends ArrayAdapter<IssueFeed> {
public List<IssueFeed> issueFeedList;
public IssueAdapter(Context context, int textViewResourceId, List<IssueFeed> issueFeedList) {
super(context, textViewResourceId, issueFeedList);
this.issueFeedList = issueFeedList;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = convertView;
IssueHolder issueHolder = null;
if (convertView == null) {
view = View.inflate(XMLParseActivity.this, R.layout.issue_list_item, null);
issueHolder = new IssueHolder();
issueHolder.issueConnectedType = (TextView) view.findViewById(R.id.result_connected_type);
issueHolder.issueSymptomView = (TextView) view.findViewById(R.id.result_symptom);
view.setTag(issueHolder);
} else {
issueHolder = (IssueHolder) view.getTag();
}
IssueFeed issueFeed = issueFeedList.get(position);
issueHolder.issueConnectedType.setText(issueFeed.getConnected_type());
issueHolder.issueSymptomView.setText(issueFeed.getSymptom());
//THE DATA I WANT TO USE IN MY INTENT
result_solution = issueFeed.getSolution();
result_comments = issueFeed.getComments();
result_connectedtype = issueFeed.getConnected_type();
result_problem = issueFeed.getProblem();
result_symptom = issueFeed.getSymptom();
return view;
}
}
static class IssueHolder {
public TextView issueSymptomView;
public TextView issueConnectedType;
}
#Override
public void onItemClick(AdapterView<?> adapterView, View v, int position, long id) {
//Put the strings in intent extra
Intent intent = new Intent(this, SpecificIssueActivity.class);
intent.putExtra("symptom", result_symptom);
intent.putExtra("problem", result_problem);
intent.putExtra("solution", result_solution);
intent.putExtra("comments", result_comments);
intent.putExtra("connectedtype", result_connectedtype);
startActivity(intent);
}
The listAdapter is set in a asynctask in the below code
public class DoLocalParse extends AsyncTask<String, Void, List<IssueFeed>> {
ProgressDialog prog;
String jsonStr = null;
Handler innerHandler;
#Override
protected void onPreExecute() {
prog = new ProgressDialog(XMLParseActivity.this);
prog.setMessage("Loading....");
prog.show();
}
#Override
protected List<IssueFeed> doInBackground(String... params) {
mIssueParser = new IssueParser(null);
mIssueList = mIssueParser.parseLocally(params[0]);
return mIssueList;
}
#Override
protected void onPostExecute(List<IssueFeed> result) {
prog.dismiss();
runOnUiThread(new Runnable() {
#Override
public void run() {
mIssueAdapter = new IssueAdapter(XMLParseActivity.this, R.layout.issue_list_item,
mIssueList);
int count = mIssueAdapter.getCount();
if (count != 0 && mIssueAdapter != null) {
mIssueListView.setAdapter(mIssueAdapter);
}
}
});
}
}
And my model IssueFeed looks like this
public class IssueFeed implements Serializable {
private String connected_type;
private String symptom;
private String problem;
private String solution;
private String comments;
public IssueFeed() {
}
public IssueFeed(String connected_type, String symptom, String problem, String solution, String comments) {
this.connected_type = connected_type;
this.symptom = symptom;
this.problem = problem;
this.solution = solution;
this.comments = comments;
}
public String getConnected_type() {
return connected_type;
}
public String getSymptom() {
return symptom;
}
public String getProblem() {
return problem;
}
public String getSolution() {
return solution;
}
public String getComments() {
return comments;
}
public void setConnected_type(String connected_type) {
this.connected_type = connected_type;
}
public void setSymptom(String symptom) {
this.symptom = symptom;
}
public void setProblem(String problem) {
this.problem = problem;
}
public void setSolution(String solution) {
this.solution = solution;
}
public void setComments(String comments) {
this.comments = comments;
}
}
I have solve the issue by getting the data from some simple methods in my model to obtain the values.
