Tring to do a spinner and i am getting errors

[jawann jefferson]

I am trying to do a spinner but i keep getting errors in my code. I followed the tutorials and tried to fit it to my needs but it doesn't seem to be working. I think the problems lies in the fact i'm not sure how to code these views if they are not in an activity all by themselves. Most tutorials have them in a single activity. But i am coding for a tablet and the exist within a fragment. Those are just my thoughts and here is the errors:

The method onCreate(Bundle) of type PatientFormFragment.NewPatientTask.GenderSpinner must override a superclass method from the "public void onCreate(Bundle savedInstanceState)"


The method onCreate(Bundle) is undefined for the type View for super.onCeate(savedInstanceState)

public class GenderSpinner extends View
	{
		public GenderSpinner(Context context) {
			super(context);
		}


		Activity gs;
		@Override
		public void onCreate(Bundle savedInstanceState)
		{
				
				
			super.onCreate(savedInstanceState);
			gs.setContentView(R.layout.patientinfocell); 
			

			
			setRetainInstance(true);
			final Spinner spinner = (Spinner) gs.findViewById(R.id.gen_spinner);
			String[] items = getResources().getStringArray(R.array.gender);
			ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(AdmissionsHome.this, items, android.R.layout.simple_spinner_item);
			adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); //platform view
			spinner.setAdapter(adapter);
				
			spinner.setOnItemSelectedListener(new GenderItemSelectedListener());
				
		}
			
		public class GenderItemSelectedListener implements OnItemSelectedListener 
		{
					
			 public void onItemSelected(AdapterView<?> parent,
			    View view, int pos, long id) {
				final Spinner spinner = (Spinner) gs.findViewById(R.id.gen_spinner);

			    String select = spinner.getSelectedItem().toString();
			     } 
		}
				
				
		public void onNothingSelected(AdapterView<?> parentView)
		 {
		            
		 }
		}
	}

thats just the code for the spinner...if you need i can post the code for the whole fragment...but it is very long. I ask that you please be patient with me. I'm new and been working on these problems for over 2 months and have been kicked off other various help sites because my questions weren't good enough. But i find it hard to form correct questions when i'm not sure what the real problems are.
thanks

onCreate is a method in Activity, not in View. In a View, you can get the Activity by casting the Context object that gets passed into the constructor.

[jawann jefferson]

Is this what you mean by casting Context with Activity:

public class GenderSpinner extends View
	{
		Activity context;
	
		public GenderSpinner(Context context) {
			super(context);
		}


		Activity gs;
		@Override
		public void onCreate(Bundle savedInstanceState)
		{
				

i am still getting the same error... eclipse is asking me to remove the "@Override"

[Tim Moores]

Again: onCreate is a method of Activity, not View. It has no place in this class.

If you want to use the Activity object, the code would look something like this:

public class GenderSpinner extends View {
    Activity act;
	
    public GenderSpinner (Context context) {
        super(context);
        this.act = (Activity) context;
    }

....

It sounds a bit as if you do not fully understand how Views interact with the main Activity (or other Activities, there can be several in an app).

[jawann jefferson]

My next question is do i need to use onCreate since its already used in the fragment? and just write code on how the spinner is supposed to work?

[Tim Moores]

Every subclass of Activity has an onCreate method, but not subclasses of View.

[jawann jefferson]

Ok here's my new code. I deleted all that onCreate stuff cause i didn't need it but now i'm getting a new error

public class GenderSpinner extends View{
			public GenderSpinner(Context context) {
				super(context);
			}
			Activity gs;
			GenderSpinner(this); //replaced setConentView
			
				

			
				
			final Spinner spinner = (Spinner) view.findViewById(R.id.gen_spinner);
			ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.gender_array, android.R.layout.simple_spinner_item);
			adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); //platform view
			spinner.setAdapter(adapter);
				
			spinner.setOnItemSelectedListener(new GenderItemSelectedListener());
				
			}
			
			public class GenderItemSelectedListener implements OnItemSelectedListener {
					
			    public void onItemSelected(AdapterView<?> parent,
			      View view, int pos, long id) {
					final Spinner spinner = (Spinner) view.findViewById(R.id.gen_spinner);

			      String select = spinner.getSelectedItem().toString();
			      
			    }
				
				
		        public void onNothingSelected(AdapterView<?> parentView) {
		            
		        }
			}
		}*/
    }
}

for GenderSpinner(this); i'm getting "Syntax error on token "this", ( expected after this token". Not sure why. I tried R.layout.patientformfragment (name of fragment it is in) and got the same error. I also tried admissionshome (name of activity it is in) and still got the same error
