I Want To Itemonclicklister in Fragment on Spinner - android-studio

Question

This Is Main Fragment
Fragment:
private void getStock() {
dialog.show();
Retrofit retrofit = RetrofitClient.getRetrofitInstance();
apiInterface api = retrofit.create(apiInterface.class);
Call<List<Blocks>>call = api.getVaccineBlocks();
call.enqueue(new Callback<List<Blocks>>() {
#Override
public void onResponse(Call<List<Blocks>>call, Response<List<Blocks>> response) {
if (response.code() == 200) {
block = response.body();
spinnerada();
dialog.cancel();
}else{
dialog.cancel();
}
}
#Override
public void onFailure(Call<List<Blocks>> call, Throwable t) {
dialog.cancel();
}
});
}
private void spinnerada() {
String[] s = new String[block.size()];
for (int i = 0; i < block.size(); i++) {
s[i] = block.get(i).getBlockName();
final ArrayAdapter a = new ArrayAdapter(getContext(), android.R.layout.simple_spinner_item, s);
a.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
//Setting the ArrayAdapter data on the Spinner
spinner.setAdapter(a);
}
}

package com.smmtn.book.models;

this.blockName = blockName;
}
public String getBlockSlug() {

First of all, you need to implement setOnItemSelectedListener. Refer to this https://stackoverflow.com/a/20151596/9346054
Once you selected the item, you can call them by making a new method. Example like below
public void onItemSelected(AdapterView<?> parent, View view, int pos,long id) {
Toast.makeText(parent.getContext(),
"OnItemSelectedListener : " + parent.getItemAtPosition(pos).toString(),
Toast.LENGTH_SHORT).show();
final String itemSelected = parent.getItemAtPosition(pos).toString();
showBlockSlug(itemSelected);
}
And then, at the method showBlockSlug() , you can call Retrofit.
private void showBlockSlug(final String blockslug){
final String url = "http://example.com/block/"+ blockslug;
//Do your stuff...
}
