There are two spinners in my application.when i select a value from one spinner, according to the selection, values will be loaded to second spinner. The problem is when i select the second spinner, the application unfortunately stops. Thanks in advance.
public class CreateAppointment extends AppCompatActivity {

Looks like you initialize the second spinner spLecturer, and then immediately after you make a call to spLecturer.getSelectedItem().toString(), which I believe will return null at this point.
Perhaps you intended to add an OnItemSelectedListener to it first?

I have a Spinner and a RecyclerView and the RecyclerView is used to display the data that I fetch from the database but the on RecyclerView, I have 2 rows of the same thing when I select the second option on the Spinner.
I have tried switch loop, changing adapter and changing api url.
Spinner spinner = (Spinner) findViewById(R.id.spinner);
adapterspinner = ArrayAdapter.createFromResource(this,R.array.planets_array,android.R.layout.simple_spinner_item);
adapterspinner.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapterspinner);
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
if(i==0)
{
loadt1trolley();
}
if(i==1)
{
loadalltrolley();
}
}
#Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
});
private void loadalltrolley(){
StringRequest stringRequest = new StringRequest(Request.Method.GET, PRODUCT_URL,new Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {
JSONArray products = new JSONArray(response);
for(int i =0;i<products.length();i++){
JSONObject productObject = products.getJSONObject(i);
String gate_no = productObject.getString("gate_no");
String dock_name = productObject.getString("dock_name");
String dock_desc = productObject.getString("dock_desc") ;
int flight_arrival = productObject.getInt("flight_arrival");
int trolley_count = productObject.getInt("trolley_count");
Product product = new Product(gate_no,dock_name,dock_desc,flight_arrival,trolley_count);
allterminalList.add(product);
}
allterminaladapter = new ProductAdapter(alert.this,allterminalList);
recyclerView.setAdapter(allterminaladapter);
int count = allterminaladapter.getItemCount();
int i =0;
if (count>0)
{
displayNotification();
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override

}
});

refresh(6000);
}
private void loadt1trolley(){
StringRequest stringRequest1 = new StringRequest(Request.Method.GET, T1_URL,
new Response.Listener<String>() {
#Override

try {

{

}

}
});
Volley.newRequestQueue(this).add(stringRequest1);
refresh(6000);
}
I expect the output to display according to the URL display with 1 row each data but it is displaying 2 row when I press position 1 on spinner
You need to clear allterminalList before making a new network request
allterminalList.clear();
if(i==0)
{
loadt1trolley();
}
else if(i==1)
{
loadalltrolley();
}
Add the code in onItemSelected() method of the Spinner, this should fix the issue.
After a long search on the internet I couldn't find any solution to meet my requirements.
I have one array list which is passed into the dialog fragment, but my requirement is:
When the user selects the date it calls the web service again and gets another data according to data and passes the same dialog fragment. How can I achieve that ? I have tried with static value but its not clearing the value. My code is:
public static class DatePickerDialogFragment extends DialogFragment implements
DatePickerDialog.OnDateSetListener
{
String userName;
public interface UserUserIdListener {
void updateIdUserName(String userName);
}
public static final int FLAG_START_DATE = 0;
public static final int FLAG_END_DATE = 1;
public static List<Orederlist>reportorderIdList=new ArrayList<>();
// private List<Userlist> reportUserList = new ArrayList<>();
private int flag = 0;
#NonNull
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
Calendar calendar = Calendar.getInstance();
int year = calendar.get(Calendar.YEAR);
int month = calendar.get(Calendar.MONTH);
int day = calendar.get(Calendar.DAY_OF_MONTH);
return new DatePickerDialog(getActivity(), this, year, month, day);
}
public void setFlag(int i) {
flag = i;
}
#Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
Calendar calendar = Calendar.getInstance();
Calendar calendar1=Calendar.getInstance();
calendar1.set(year, monthOfYear, dayOfMonth);
calendar.set(year, monthOfYear, dayOfMonth);
String reportOrderIds="";
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");
if (flag == FLAG_START_DATE) {
textviewFromDate.setText(format.format(calendar.getTime()));
fromDateReport=textviewFromDate.getText().toString();
JSONObject pieObject = new JSONObject();
try
{

progressDialog.show();
} catch (Exception e)

}
// String TAG = "delivered";

}
and for dialog fragment pass data is :
FragmentManager managerOrderIds = getSupportFragmentManager();
UserJobIds dialogOrderIds = new UserJobIds();
dialogOrderIds.setdata(orderIdList,reportorderIdList);//with static array list which is not claer the value
dialogOrderIds.show(managerOrderIds, "Dialog");
What you can do is just create a newInstance of Dialog Fragment assign data to it, then call show().Below is an example.
public class D2Fragment extends DialogFragment {
private ArrayList<String> list;
public static D2Fragment getInstanceFor(ArrayList<String> list){
D2Fragment d2Fragment=new D2Fragment();
d2Fragment.list=list;
return d2Fragment;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.item_dialog, container,
false);
getDialog().setTitle("DialogFragment Sample");
Log.e("size",list.size()+"");// Here is the list
// Do something else
return rootView;
}
}
When you show dialog.
ArrayList<String> list=new ArrayList<>();
list.add("Val1");
list.add("Val2");
D2Fragment d2Fragment=D2Fragment.getInstanceFor(list);
d2Fragment.show(getSupportFragmentManager(),"dialog2");
Or just create a setter for your data.
public class D2Fragment extends DialogFragment {
private ArrayList<String> list;
public void setData(ArrayList<String> list){
this.list=list;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.item_dialog, container,
false);
getDialog().setTitle("DialogFragment Sample");
Log.e("size",list.size()+"");// Here is the list
// Do something else
return rootView;
}
}
and to show Dialog.
ArrayList<String> list = new ArrayList<>();
list.add("Val1");
list.add("Val2");
D2Fragment d2Fragment = new D2Fragment();
d2Fragment.setData(list);
d2Fragment.show(getSupportFragmentManager(), "dialog2");
In activity you can always find that particular DialgFragment by tag you assigned at the time of transaction.
Fragment fragment=getSupportFragmentManager().findFragmentByTag("dialog2");
if(fragment!=null && fragment instanceof D2Fragment){
((D2Fragment)fragment).call();// You can call any public method of this dialog fragment here
}
Hi Now I'm retrieving data to spinner dynamically, but now it displaying some id's but those Id details are stored in other table, I want display those details in the spinner instead of id. And if I select particular product in spinner according that product details should display in list.
I'm using Retrofit method for retrieving data from server

I am assuming that your product_name = businessgroups.get(0).getProduct(); is getting a pruduct.
First of all please remove this part
product_name = businessgroups.get(0).getProduct();
List<PosmultistoresModel> list=null;
for(i=0;i<businessgroups.size();i++)
{
list=businessgroups;
}
items = new String[list.size()];
for(int i=0; i<businessgroups.size(); i++){
//Storing names to string array
items[i] = list.get(i).getProduct();
}
then can you try
ArrayList<String> productList = new ArrayList<>();
for (int i = 0; i < businessgroups.size(); i++) {
productList.add(businessgroups.get(i).getProduct());
}
And finally
adapter1 = new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_spinner_dropdown_item, productList);
i have 3 spinners if i select something it should show items related with that selection .But its showing all the item from server and not taking selected item.
In getdata() methode in code i am getting all item without selection .
In filter() methode i need to show only selected item, but its still showing all item.

you don't changed adapter data.
try this code.

You can Log your post parameters i think you should do :
final String lstrain = (String)lsStrain.getSelectedItem();
I have got 3 spinner where data is coming from server, if we click the search button without selecting any spinner then on next activity , it should show all list(all product without condition), but if we select according to 3 spinner then it should show only related item.I am getting all item when clicking search button without selecting anything but i am not getting selected item in next activity .

In Pigeon listing activity there is 1 option like search activity where user can search without selecting any item just like in search activity.
Set listeners for each of your spinners
setOnItemSelectedListener
In onItemSelected method , get the selected value in a variable and pass on these values to next activity.
E.g.
yourSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
String yourValue = yourSpinner.getSelectedItem().toString();
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
