Creating Options Menus for Google Glass

Question

Going by the guidelines and conventions in the StopWatch GDK example, I cannot get the MenuOption to open.

My app compiles and able to output the embedded log statement of ""@@@@TEST", but no OptionsMenu appears.

https://developers.google.com/glass/develop/gdk/ui/immersion-menus

This is the method in the Android API for menu's.

openOptionsMenu();

I'm basing the code off of stopwatch's conventions:

/*
 * 
 * Menu Code
 */
protected void onCreate(Bundle savedInstanceState){ 
    super.onCreate(savedInstanceState);
}

 @Override
public boolean onKeyDown(int keycode, KeyEvent event) {
    if (keycode == KeyEvent.KEYCODE_DPAD_CENTER) {
        openOptionsMenu();
        Log.v("@@@@","TEST");
        return true;
    }
    return false;
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.menu, menu);
    return true;
}
@Override
public boolean onPrepareOptionsMenu(Menu menu) {
    // Implement if needed
    return false;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle item selection. Menu items typically start another
    // activity, start a service, or broadcast another intent.
    switch (item.getItemId()) {
        case R.id.stop:
            //startActivity(new Intent(this, StopStopWatchActivity.class));
            Log.v("@@@@","HI");
                return true;
        case R.id.read_aloud:
            Log.v("@@@@","READ_ALOUD");
            return true;
        default:
            return super.onOptionsItemSelected(item);
    }
}
    //open the optionsMenu to make sure
@Override
public void openOptionsMenu() {
        super.openOptionsMenu();

}

the XML for menu

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:id="@+id/read_aloud"
        android:title="@string/read_aloud"
        android:icon="@drawable/ic_launcher"/>
    <item
        android:id="@+id/stop"
        android:title="@string/stop"
        android:icon="@drawable/ic_launcher"/>
</menu>

Answer 1

edit: I discovered what my issue was. I commented out the prepared option which was returning false, which caused my options to not engaged.

Here in reference is a good example to do it properly.

Thanks @w9jds for his help.

I can't find what the issue was in my code, but here is a working example solutions with the correct menu creation and one tap.

https://github.com/w9jds/GlassMenuExample

What the program does is show a glass app that renders a hello world card. On Tap the card creates an options menu that has the 'share' option.

This functionality is a lot similar to how cards work on the timeline.

Menu - Main.Xml

<menu xmlns:android="http://schemas.android.com/apk/res/android" >

     <item
        android:id="@+id/share_menu_item"
        android:title="@string/share_label"
        android:icon="@drawable/ic_share_50"/>

</menu>

    private AudioManager maManager;

    @Override
    protected void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);

        //initialize the audio manager
        maManager = (AudioManager) getSystemService(this.AUDIO_SERVICE);
        //create gesture listener
        mGestureDetector = createGestureDetector(this);

        //create a new card for the view
        Card cView = new Card(this);
        //set the text of the card to the hello world string
        cView.setText(R.string.hello_world);
        //set the card as the content view
        setContentView(cView.toView());


    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu)

    @Override

        // Handle item selection. Menu items typically start another
