Android: Start activity from a MenuItem

I'm new on Android, and I'm trying to start an Activity from a MenuItem choose of the user.

Actually, I'm building my menu (and is working OK) from my main activity class using a MenuInflater:

    public boolean onCreateOptionsMenu(Menu menu) 
        //the Menu Inflater class allows to create a menu from a XML File
        MenuInflater inflater = new MenuInflater(this);
        return true;

And im handling the Menu selection using the following code (working fine too):

public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) 

    return false;

I have a second and last activity called AddWebsite, and i would like to start it, but the following code doesnt work:

protected void ShowScreenAddSite()
    Intent i = new Intent(AddWebsite.class);


Do you know what is the extra thing that I have to pass to the Intent constructor?

Answer 1

the solution was too simple, appears that in android, every activity class is not automatically referenced in the manifest.xml.

I just only add the new activity to the manifest, and works fine.

Answer 2

I'm still quite new to android myself but don't you need to be passing a context to the Intent constructor?

protected void ShowScreenAddSite()
    Intent i = new Intent(this, AddWebsite.class);


You're probably doing this from inside an activity so I think you should be using 'this'

You can also do something like this

/* (non-Javadoc)
 * @see
public boolean onCreateOptionsMenu(Menu menu) {
    final MenuInflater inflater = new MenuInflater(this);
    final Intent[] menuIntents = new Intent[] {
              new Intent(this, AddWebsite.class) };
    inflater.inflate(, menu);
    final int ms = menu.size();
    for (int i=0; i < ms; i++) {
    return super.onCreateOptionsMenu(menu);

avoiding some method calls, however you need to pay attention to the mapping between menu ids, menu order and intents but this is almost always known.
