Yes it is possible to convert JavaObject into json object. Well it is not clear where you want to send response. If you want to send the object to another activity or another fragment then this approach will be the somehow good and easy. First create a DataModel class or POJO class. Like I named it as TestModel and create 3 fields you above mentioned. public class TestModel { int Id; String Gender; String Categories; public int getId() { return Id; } public void setId( int id) { Id = id; } public String getGender() { return Gender; } public void setGender(String gender) { Gender = gender; } public String getCategories() { return Categories; } public void setCategories(String categories) { Categories = categories; } } Now from spinner click listener spinner.setOnItemSelectedListener( new OnItemSelectedListener() { public void onItemSelected(AdapterView parent, View view, int position, long id) { String gender = parent.getItemAtPosition(position).toString(); } public void onNothingSelected(AdapterView parent) { } }); From there you will get gender. Now set values in the Pojo class by making its object. TestModel tst = new TestModel(); tst.setCategories( "Android" ); tst.setGender(gender); tst.setId( 101 ); String resp = new Gson().toJson(tst); Now to see if its is converted into JSONObject let get it logged. Log.e( "response Tst" , resp); Output : E/response Tst: {"Categories":"Android","Gender":"Male","Id":101} For JsonObject to work we need a library for serialization and deserialization Add the following code to dependencies in build.gradle of app level. dependencies { implementation 'com.google.code.gson:gson:2.8.6' }

Yes, Fetch the selected item from spinner then do your stuff based on that. https://www.android-examples.com/get-selected-item-value-from-spinner-in-android-example/
