I have 3 spinner in my Home Activity.If i select 1 other should change according to 1st spinner.I have Country, City and Location as spinner, if i select country then city and location should change according to that.Till now i manage to get country item in spinner (item from database).Now how to get only selected item in spinner..i m confused.??
here is my Home Activity(where i am getting spinner (country) item):
public class Home extends AppCompatActivity implements AdapterView.OnItemClickListener, AdapterView.OnItemSelectedListener {

countrySpinner .setOnItemSelectedListener(this);
country_list = new ArrayList<String>();
//location_list = new ArrayList<String>();
// city_list = new ArrayList<String>();
getData();
}
private void getData(){

//Calling method getCountry to get the Country from the JSON Array
getCountry(result);
} catch (JSONException e) {

//Traversing through all the items in the json array
List<Country> countries = new ArrayList<>();
try {

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,

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>

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.
Hi everyone I have one question. I want to retrieve the data from the Firebase live database and it keeps telling me that it doesn't find the getter and the setter but as you can see below I did it, I create a class where I have the setter and the getter with the same name of the database fields.
Can anyone tell me what I'm doing wrong because I don't have a clue?
Thank you in advance.
Photo of the database:
Code of the Activity and the Class where you can see that I have the getter and the setter.
package com.example.ipill;
public class CartActivity extends AppCompatActivity {
private TextView total;

pay = findViewById(R.id.pay);
mResultList.setHasFixedSize(true);
mResultList.setLayoutManager(new LinearLayoutManager(this));
// Attach a listener to read the data at our posts reference
mUserDatabase.addValueEventListener(new ValueEventListener() {
#Override

System.out.println("DATAAAA: "+post);

In addition to other answer, To get Users_get data, according your database structure you have to go one level more.
Currently your database reference pointed to Cart. So iterate through children of cart to get cart data. Check below:
mUserDatabase = FirebaseDatabase.getInstance().getReference("Cart");
mUserDatabase.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
for(DataSnapshot childSnapshot : dataSnapshot.getChildren()) {
Users_get post = childSnapshot.getValue(Users_get.class);
System.out.println("DATAAAA: " + post);
}
}
#Override
public void onCancelled(DatabaseError databaseError) {
System.out.println("The read failed: " + databaseError.getCode());
}
});
Change the class to this:
public class Users_get {
private String name, surname;
private Long price;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSurname() {
return surname;
}
public void setSurname(String surname) {
this.surname = surname;
}
public Long getPrice() {
return price;
}
public void setPrice(Long price) {
this.price = price;
}
public Users_get(String name,Long price,String surname) {
this.price = price;
this.name = name;
this.surname = surname;
}
public Users_get() {
}
Since you are using an IDE, then just click generate getters and setters and it will automatically do that for you instead of manually writing the methods..
You get the warning because in your Users_get class you don't have correct getters for your fields. If you have a field named name, the correct getter should be:
public String getName() {
return name;
}
And not:
public String getname() {
return name;
}
See the capital N versus lowercase n? To solve this you should change all the names of all getters in your Users_get class, as explained above.

hare i am calling the adapter and pass parameters
From city object you can directly get province_id
I need to Show Registration Form With Spinner Using Fragments and get the data using Json
This is kind of register form. At the bottom we have change language button which will reset the form and will be shown in arabic / english.
[
{
"Id":1,
"TitleEN":"Kuwait",
"TitleAR":"الكويت",
"CurrencyId":1,
"CurrencyEN":"Kuwaiti Dinar",
"CurrencyAR":"دينار كويتى",
"CodeEN":"KWD",
"CodeAR":"د.ك",
"Code":"965"
},
{
"Id":2,
"TitleEN":"Emirates",
"TitleAR":"الإمارات",
"CurrencyId":2,
"CurrencyEN":"Emirati Dirham",
"CurrencyAR":"درهم إماراتي",
"CodeEN":"AED",
"CodeAR":"درهم",
"Code":"971"
},
{
"Id":3,
"TitleEN":"Saudi Arabia",
"TitleAR":"السعودية",
"CurrencyId":3,
"CurrencyEN":"Saudi Riyal",
"CurrencyAR":"ريال سعودى",
"CodeEN":"SAR",
"CodeAR":"ر.س",
"Code":"966"
}
]
Note.I assume you have followed the first 3 steps from this [question][1]
and will start from the following
Step 1
Add spinner in xml
<Spinner
android:id="#+id/spinner"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:prompt="#string/spinner_title" />
Step 2
In ApiInterface Class add the following code
#GET("/app/app.asmx/GetCountries")
Call<List<Country>> getCountry();
Step 3
Create new model class by name Country
public class Country {
#SerializedName("Id")
#Expose
private Integer id;
#SerializedName("TitleEN")
#Expose
private String titleEN;
#SerializedName("TitleAR")
#Expose
private String titleAR;
#SerializedName("CurrencyId")
#Expose
private Integer currencyId;
#SerializedName("CurrencyEN")
#Expose
private String currencyEN;
#SerializedName("CurrencyAR")
#Expose
private String currencyAR;
#SerializedName("CodeEN")
#Expose
private String codeEN;
#SerializedName("CodeAR")
#Expose
private String codeAR;
#SerializedName("Code")
#Expose
private String code;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getTitleEN() {
return titleEN;
}
public void setTitleEN(String titleEN) {
this.titleEN = titleEN;
}
public String getTitleAR() {
return titleAR;
}
public void setTitleAR(String titleAR) {
this.titleAR = titleAR;
}
public Integer getCurrencyId() {
return currencyId;
}
public void setCurrencyId(Integer currencyId) {
this.currencyId = currencyId;
}
public String getCurrencyEN() {
return currencyEN;
}
public void setCurrencyEN(String currencyEN) {
this.currencyEN = currencyEN;
}
public String getCurrencyAR() {
return currencyAR;
}
public void setCurrencyAR(String currencyAR) {
this.currencyAR = currencyAR;
}
public String getCodeEN() {
return codeEN;
}
public void setCodeEN(String codeEN) {
this.codeEN = codeEN;
}
public String getCodeAR() {
return codeAR;
}
public void setCodeAR(String codeAR) {
this.codeAR = codeAR;
}
public String getCode() {
return code;
}
public void setCode(String code) {
this.code = code;
}
}
Step 4
find view in activity or fragment and add call the request and get response and add the response in spinner adapter.Initialize a string list out side the onCreate method
List<String> codes = new ArrayList<String>();
APIInterface apiInterfacePages;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Spinner spinner = (Spinner) findViewById(R.id.spinner);
apiInterfacePages= PageApiClient.getRetrofit().create(APIInterface.class);
Call<List<Country>> getCountry = apiInterfacePages.getCountry();
getCountry.enqueue(new Callback<List<Country>>() {
#Override
public void onResponse(Call<List<Country>> call, Response<List<Country>> response) {
countryList = response.body();
for (int i = 0; i < countryList.size(); i++) {
codes.add(countryList.get(i).getCode());
}
ArrayAdapter<String> adapterTime = new ArrayAdapter<>(MainActivity.this, android.R.layout.simple_spinner_dropdown_item, codes);
spinner.setAdapter(adapterTime);
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
Toast.makeText(MainActivity.this, "" + countryList.get(i).getTitleEN(), Toast.LENGTH_SHORT).show();
}
#Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
});
}
#Override
public void onFailure(Call<List<Country>> call, Throwable t) {
}
});
}
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;
}
