Create dynamic spinner in android

I have to create a form in Android which may contain spinner or may not, based on data we have to create spinner. So I am trying to create a dynamic spinner in the form. But it is not working. I am able to create the spinner but when I click on the spinner it show error message.

Code that I wrote:

dynamicSpinner = new Spinner(getApplicationContext());
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line, option);

adapter.setDropDownViewResource(android.R.layout.simple_dropdown_item_1line);
dynamicSpinner.setAdapter(adapter);

option is a ArrayList<String>, which content the list of the options.

If anyone have solution please share with me.

try this 

Spinner s=new Spinner(yourActivity.this);
ParentLayout.addView(s);

I dont see you adding your spinner to parent layout. I am more interested in what error are you getting exactly

Have you tried viewflipper?

http://developer.android.com/reference/android/widget/ViewFlipper.html

Its effective especially for those in need in multiple views/widgets.

The thing is just that, the widgets/views that will be viewed/added is defined in xml.

Hope it helps :D

Have a spinner in your xml, then in activity, use following:

dynamicSpinner = (Spinner)findViewbyID(spinner ID);

if(data available)
    populate the spinner;
else
    dynamicSpinner.setVisibility(View.Gone);

Hope it helps.

EDIT : Incase you want to add spinner progarammatically, still you would be having a layout in xml which you are using in setContentView(layout id).. so get the layout in which all the childs are present in xml throught its id and then add spinner to that layout.

Include a spinner in your xml with an id..

and then in code , use:

dynamicSpinner = (Spinner)findViewById(R.id.mydynamicspinner);

instead of 

dynamicSpinner = new Spinner(getApplicationContext());

rest all looks fine...
