Seeking guidance: how to customize the content under Android menu key on your phone?

Android ContextMenu customize the phone menu button mobile development

Usually when we click the menu button on Android phones, it will pop up a list of menu options, so that we can carry out other operations. In Android program for a View (such as an EditText) is relatively easy to add menu functions, such as:
this.registerForContextMenu (mEditText); then rewrite onCreateContextMenu () method on the line, press the EditText after our custom pop-up menu.
I want to add menu functions to their Android application, that is, to achieve: the phone's menu button is lit, and when I click the menu button on the phone after the pop-up list of my custom menu options. I do not know how?<-! Main posts under Banner (D4) -><-! Posts under the main text (D5) ->

activity code:

 @ Override 
public boolean onCreateOptionsMenu (Menu menu) {
/ / Inflate the menu; this adds items to the action bar if it is present 
.getMenuInflater (). inflate (R.menu.option, menu) ;/ / option.xml defined 
 under res / menu / directoryreturn true; 
} 

@ Override 
public boolean onOptionsItemSelected (MenuItem item) {
switch (item.getItemId ()) {
case R.id.menu_settings: 
/ / Do something 
break; / / later processed here can return true; 
} 
/ / TODO Auto-generated method stub 
return super.onOptionsItemSelected (item); 
} 

res / menu / option.xml, menus are defined here.

  

android: id = "@ + id / menu_settings" 
android: orderInCategory = "100" 
android: showAsAction = "never" 
android: title = "@ string / menu_settings" />

Thank you! Know, the new general engineering Activity in Android will automatically rewrite a onCreateOptionMenu () method, but I have not used it to go, always like what Button to replace it with.
It is necessary to look into the matter, thank you tantahe!
