I recently started with android development, so was just stucked.
I want to create an explore_fragment in which list of users is added in recyclerView and with view_profile button we can view user profile.

As expected, the following error:
com.google.firebase.database.DatabaseException: Failed to convert a value of type java.lang.String to int
Arrives due to the fact that an int-type field holds a value of type String. So when deserializing, the guidedCount field is expected to hold a value of type int and not String, hence the error. The node that is responsible for the Exception is:
"guidedCount": "gAzcrP1IYmQI0ht4qfH9WGt9U7F2",
See, it holds a UID rather than a number. So to solve this, change that UID with a number.

Android Java - Parse Array Entry of JSON into Recycler View

I am trying to parse a Block of JSON into a RecyclerView. So far I was able to achieve this with a quite flat JSON Structure. But now I have an Array-Entry in my JSON File where I always want to get the first Entry.
The JSON looks like this:
[
{
"MatchID": 60989,
"Team1": {
"TeamName": "FC Bayern München",
"TeamIconUrl": "https://i.imgur.com/jJEsJrj.png"
},
"Team2": {
"TeamName": "VfL Wolfsburg",
"TeamIconUrl": "https://i.imgur.com/ucqKV4B.png"
},
"MatchResults": [
{
"PointsTeam1": 4,
"PointsTeam2": 0,
"ResultOrderID": 1
},
{
"PointsTeam1": 1,
"PointsTeam2": 0,
"ResultOrderID": 2
}
]
},
{
"MatchID": 60990,
"Team1": {
"TeamName": "VfL Bochum",
"TeamIconUrl": "https://i.imgur.com/5jy3Gfr.png"
},
"Team2": {
"TeamName": "1. FC Union Berlin",
"TeamIconUrl": "https://upload.wikimedia.org/wikipedia/commons/4/44/1._FC_Union_Berlin_Logo.svg"
},
"MatchResults": [
{
"PointsTeam1": 0,
"PointsTeam2": 1,
"ResultOrderID": 1
},
{
"PointsTeam1": 0,
"PointsTeam2": 1,
"ResultOrderID": 2
}
]
}
]
My Activity fetches this JSON from an API using Retrofit2
private void parseJson() {
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("https://www.openligadb.de/api/")
.addConverterFactory(GsonConverterFactory.create())
.build();
RequestInterface request = retrofit.create(RequestInterface.class);
Call<List<Match>> call=request.getMatchJson();
call.enqueue(new Callback<List<Match>>() {
#Override
public void onResponse(Call<List<Match>> call, Response<List<Match>> response) {
if (response.isSuccessful() && response.body() != null) {
matchList = new ArrayList<>(response.body());
matchAdapter = new MatchAdapter(matchList, ActivityMatch.this);
mRecyclerView.setAdapter(matchAdapter);
}
}
#Override
public void onFailure(Call<List<Match>> call, Throwable t) {
Log.println(Log.ERROR, "FAILED", String.valueOf(t));
Toast.makeText(ActivityMatch.this, "Oops! Somehting went wrong!", Toast.LENGTH_SHORT).show();
}
});
}
My MatchAdapter is then parsing this Data for the View. Here I want to display whatever is the first in MatchResults then using PointsTeam1 and PointsTeam2 to display something like "4 : 0"
Now in my ModelClass accessing direct Values like the TeamName and TeamIconUrl worked but I am struggeling to get to the first entry of the Array and am really stuck on even how to properly approach this issue.
The Adapter Class:
public class MatchAdapter extends RecyclerView.Adapter<MatchAdapter.MatchHolder>{
private ArrayList<Match> matchList;
private Context context;
public MatchAdapter(ArrayList<Match> matchList, Context context) {
this.context = context;
this.matchList = matchList;
}
#NonNull
#Override
public MatchAdapter.MatchHolder onCreateViewHolder(#NonNull ViewGroup viewGroup, int viewType) {
View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.match_list_row_layout, viewGroup, false);
return new MatchHolder(view);
}
#Override
public void onBindViewHolder(#NonNull MatchAdapter.MatchHolder holder, int position) {
holder.tvTeam1name.setText(matchList.get(position).Team1.TeamName);
holder.tvTeam2name.setText(matchList.get(position).Team2.TeamName);
Glide.with(context).load(matchList.get(position).Team1.TeamIconUrl).into(holder.ivTeam1Logo);
Glide.with(context).load(matchList.get(position).Team2.TeamIconUrl).into(holder.ivTeam2Logo);
//This is not working
holder.tvResult.setText(matchList.get(position).MatchResults.PointsTeam1 + " : " + matchList.get(position).MatchResults.PointsTeam2);
}
#Override
public int getItemCount() {
return matchList.size();
}
public class MatchHolder extends RecyclerView.ViewHolder {
private TextView tvTeam1name, tvTeam2name, tvResult;
private ImageView ivTeam1Logo, ivTeam2Logo;
public MatchHolder(#NonNull View itemView) {
super(itemView);
tvTeam1name = itemView.findViewById(R.id.tv_team1name);
tvTeam2name = itemView.findViewById(R.id.tv_team2name);
tvResult = itemView.findViewById(R.id.tv_result);
ivTeam1Logo = itemView.findViewById(R.id.iv_team1logo);
ivTeam2Logo = itemView.findViewById(R.id.iv_team2logo);
}
}
}
My ModelClass (Left out Getters/Setters for Readability)
package de.eahjena.app.wi.fussball;
public class Match {
Team Team1;
Team Team2;
MatchResults MatchResults;
public Match(Team Team1, Team Team2, MatchResults MatchResults) {
this.Team1 = Team1;
this.Team2 = Team2;
this.MatchResults = MatchResults;
}
}
class Team {
String TeamName;
String TeamIconUrl;
public Team (String TeamName, String TeamIconUrl) {
this.TeamName = TeamName;
this.TeamIconUrl = TeamIconUrl;
}
}
class MatchResults {
String PointsTeam1;
String PointsTeam2;
public MatchResults(String PointsTeam1, String PointsTeam2) {
this.PointsTeam1 = PointsTeam1;
this.PointsTeam2 = PointsTeam2;
}
}

As per the question you are suppose to use List<MatchResults> MatchResults since the API response contains a list of match results.
Further to use the first position from the matchResults array you cna use it like this in your adapter :
matchList.get(position).MatchResults.get(0).PointsTeam1

Save the edittext data of a dynamic generated forms to server

I have generated dynamic forms according to type i.e String, int and spinner according to the json data provided by backend.
I have created a recylerview adapter and in pojo class I have added extra variable as answer and provided setter method to it.
Now, forms have generated according to type but I need to save data to server. To save data, i need to get each edittext value with respective id and type and I need to loop it but I couldnot do it so. I cannot define the edittext value with its ID and type. I hope you guys will help me.
There are three paramters to post to server,in method callRetrofitSaveForm() i. vendorId, ii. userid
iii. formData, I have problem with param iii because it has its format to pass. I have used retrofit to parse and problem is with third parameter formData.
the value format of third paramter is
[{"id":"24","label":"Customer ID","value":"102"},{"id":"25","label":"Amount","value":"2000"}]

You can grab the parent view and loop through it and get all editText.
private HashSet<EditText> getTextViews(ViewGroup root){
HashSet<EditText> views=new HashSet<>();
for(int i=0;i<root.getChildCount();i++){
View v=root.getChildAt(i);
if(v instanceof EditText){
views.add((EditText)v);
}else if(v instanceof ViewGroup){
views.addAll(getTextViews((ViewGroup)v));
}
}
return views;
}

public class Home extends AppCompatActivity implements AdapterView.OnItemClickListener, AdapterView.OnItemSelectedListener {
private Spinner countrySpinner, locationSpinner, citySpinner;
private TextView cityCodeTextView;
private Button submitButton;
private ArrayList<String> country_list, location_list, city_list;
private JSONArray result;
ProgressDialog progressDialog;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
countrySpinner = (Spinner) findViewById(Country);
//citySpinner = (Spinner) findViewById(City);
//locationSpinner = (Spinner) findViewById(R.id.Location);
countrySpinner .setOnItemSelectedListener(this);
country_list = new ArrayList<String>();
//location_list = new ArrayList<String>();
// city_list = new ArrayList<String>();
getData();
}
private void getData(){
StringRequest
stringRequest = new StringRequest(Config.DATA_URL,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
JSONObject j = null;
try {
Log.d("Test",response);
JSONArray result = new JSONArray(response);
//Calling method getCountry to get the Country from the JSON Array
getCountry(result);
} catch (JSONException e) {
e.printStackTrace();
}
}
},new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}});
RequestQueue requestQueue = Volley.newRequestQueue(this);
//Adding request to the queue
requestQueue.add(stringRequest);
}
private void getCountry(JSONArray jsonArrayCountry){
//Traversing through all the items in the json array
List<Country> countries = new ArrayList<>();
try {
String country_name, country_code;
JSONObject countries_object;
for (int i = 0; i < jsonArrayCountry.length(); i++) {
countries_object = jsonArrayCountry.getJSONObject(i);
country_code = countries_object.getString("id");
country_name = countries_object.getString("country");
countries.add(new Country(country_code, country_name));
}
ArrayAdapter countryAdapter = new ArrayAdapter<>(this, android.R.layout.simple_spinner_dropdown_item, countries);
countrySpinner.setPrompt("--Select Country--");
countrySpinner.setAdapter(countryAdapter);
countrySpinner.setAdapter(new NothingSelectedSpinnerAdapter(countryAdapter,
R.layout.contact_spinner_row_nothing_selected,this));
countrySpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
}
});
} catch (JSONException e) {
Log.e("Home", e.getLocalizedMessage(), e);
}
}
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
//Setting the values to textviews for a selected item
//textViewName.setText(getName(position));
//textViewCourse.setText(getCourse(position));
//textViewSession.setText(getSession(position));
}
//When no item is selected this method would execute
#Override
public void onNothingSelected(AdapterView<?> parent) {
// textViewName.setText("");
// textViewCourse.setText("");
//textViewSession.setText("");
}
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
}
}
this is Country.java
public class Country {
private String name;
private String id;
public Country(String id, String name) {
this.name = name;
this.id = id;
}
public String getName() {
return name;
}
public String getId() {
return id;
}
#Override
public String toString() {
return name;
}
}
this is City.java
public class City {
private String name;
public String getName() {
return name;
}
#Override
public String toString() {
return name;
}
}
this is Location.java
public class Location {
private String name;
public String getName() {
return name;
}
#Override
public String toString() {
return name;
}
}
this is Config.java
public class Config {
//JSON URL
public static final String DATA_URL = "http://demo5...../get_country.php";
public static final String DATA_URL1 = "http://demo5...../get_jsoncity.php?id=";
//Tags used in the JSON String
public static final String DATA_URL2 = "http://demo5...../get_jsonlocation.php?id=";
//Tags used in the JSON String
//JSON array name
public static final String JSON_ARRAY = "result";
}

}
]
I am already getting 1st spinner item i.e Country , i need to get item for city(2nd spinner) and location(3rd spinner) as per selection of 1st spinner.

Your country.class should have getter setter of city and location.
public class Country {
private String name;
private String id;
private Location loc;
ArrayList<City> Cityarr = new ArrayList<City>();
public ArrayList<City> getCityarr() {
return Cityarr;
}
public void setCityarr(ArrayList<City> Citya) {
this.Cityarr = Citya;
}
public Country(String id, String name) {
this.name = name;
this.id = id;
}
public String getName() {
return name;
}
public String getId() {
return id;
}
public Location getLocation() {
return loc;
}
#Override
public String toString() {
return name;
}
}
and spinner.OnItemSelectedLisenter should nested
country.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
vbopr.get(i).getCityarr().size();
cityname.clear();
cityname.add("All");
for (int j = 0; j < vbopr.get(i).getCityarr().size(); j++) {
cityname.add(vbopr.get(i).getCityarr().get(j).getCityname());
}
try {
adpcity.notifyDataSetChanged();
} catch (NullPointerException ne) {
}
adpcity = new ArrayAdapter<String>(getApplicationContext(), R.layout.spinner_items, cityname);
city.setAdapter(adpcity);
}
#Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
});
my url contains data in xml form
example
<world>
<country>
<countryid>2</countryid>
<countryname>India</countryname>
<city>
<city_id>1462</city_id>
<city_name>abc</city_name>
</city>
<city>
<city_id>1460</city_id>
<city_name>def</city_name>
</city>
<city>
<city_id>1461</city_id>
<city_name>jkl PLANT</city_name>
</city>
</country>
<country>
<countryid>3</countryid>
<countryname>Australia</countryname>
<city>
<city_id>1462</city_id>
<city_name>gdfg PLANT</city_name>
</city>
<city>
<city_id>1460</city_id>
<city_name>xdfPLANT</city_name>
</city>
<city>
<city_id>1461</city_id>
<city_name>dfgPLANT</city_name>
</city>
<city>
<city_id>617</city_id>
<city_name>dgvdfgg</city_name>
</city>
</country>
</world>

try this:
spinner_1.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int position, long arg3) {
if (spinner_1.getSelectedItem().equals("UAE")) {
//cal api url here to get data
// set adapter to spinner_2 here for "UAE" selected
} else if (spinner_1.getSelectedItem().equals("UK")) {
//same..
}
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
}
}
);
