From a lot of help here, I was able to use this code to inflate a context menu whenever an item is clicked. However, I cannot figure out how to inflate a individual, separate menus for each item. I want a different menu to pop up when a different item is clicked. Right now, no matter which item I click, the same menu pops up. How can I solve this? Here is the code I am using.

public class MainActivity extends Activity {
@Override
public void onCreateContextMenu (ContextMenu menu, View v, ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.testmenu, menu);
}
/** Called when the activity is first created.
* @return */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
MediaPlayer mp = MediaPlayer.create(this, R.raw.radio);
mp.start();
Carousel carousel = (Carousel)findViewById(R.id.carousel);
registerForContextMenu (carousel);
carousel.setOnItemClickListener(new OnItemClickListener(){
public void onItemClick(CarouselAdapter<?> parent, View view,
int position, long id) {
openContextMenu (view);
Toast.makeText(MainActivity.this,
String.format("%s has been clicked",
((CarouselItem)parent.getChildAt(position)).getName()),
Toast.LENGTH_SHORT).show();
}
@Override
public void onCreateContextMenu(ContextMenu menu,
View v, ContextMenuInfo menuInfo) {
// TODO Auto-generated method stub

This is simple in android. Only thing is you might have to add menu dynamically to the system instead of loading menu items using a xml file or load different xml menus based on the user’s selection.
here is a sample application which shows how to do this,
The above method based on a flag value inflates the different set of menu items.
Following is the onCreate() method which has a button and within that it registers for context menu every time it gets clicked.
And here is the output,
When the flag is true,
And when the flag is false,
And I believe the key is to call the
registerForContextMenu(v);when you need to load new menu items.
