how to create a common menu for an android application

For an开发者_如何转开发 android application I need to have a single menu in common that can be displayed on every screen with its structure and functionality written in another class or activity that can be used in all other activities.

---

Create baseClass Activity. There you can implement the menu structure. After that each activity extends this baseClass activity.

---

Create a MainActivity which extends ActivityGroup class and all other activity as its sub activities . Use onCreateOptionsMenu(Menu menu) method to addmenu item in MainActivity. All the other activity can show that menu items automatically.

see this:

public class MainActivity extends ActivityGroup {

 @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // TODO Auto-generated method stub
        menu.add("1");
        menu.add("2");
        return super.onCreateOptionsMenu(menu);
    }

  @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        //start other activity here
    }
}

Hope this will give you some idea on the issue.
