Answer 1

1. Open '/res/menu/menu.xml'

2. Add this code in it:

   <item
       android:id="@+id/action_about"
       android:orderInCategory="2"
       android:showAsAction="never"
       android:title="About"/>
   <item
       android:id="@+id/action_exit"
       android:orderInCategory="3"
       android:showAsAction="never"
       android:title="Exit"/>
   

3. Open '/src/(packagename)/(acitivityname).java'

4. Add this code there

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.menu, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
    case R.id.action_about:
        // About option clicked.
        return true;
    case R.id.action_exit:
        // Exit option clicked.
        return true;
    case R.id.action_settings:
        // Settings option clicked.
        return true;
    default:
        return super.onOptionsItemSelected(item);
    }
}
