How to combine Navigation Drawer and Spinner [like

Question

I need your advice. In Google+ App for Android, there are two elements, that I don't know how to put together. One is "Navigation Drawer" and second is "Action Bar Navigation Spinner". Do you know how these two elements put together?

Thank you very much for your advice! P.S. I know, I'm lame :) (and I apologize for my English)

Answer 1

Add the spinner to the NavigationBar.

The basic procedure to enable drop-down navigation is:

1.Create a SpinnerAdapter that provides the list of selectable items for the drop-down and the layout to use when drawing each item in the list.

2.Implement ActionBar.OnNavigationListener to define the behavior that occurs when the user selects an item from the list.

3.During your activity's onCreate() method, enable the action bar's drop-down list by calling setNavigationMode(NAVIGATION_MODE_LIST).

4.Set the callback for the drop-down list with setListNavigationCallbacks()

http://developer.android.com/guide/topics/ui/actionbar.html

Check the topic Adding Drop-down Navigation

Example:

    public class MainActivity extends Activity implements OnNavigationListener

Then

    getActionBar().setDisplayShowTitleEnabled(false);
    getActionBar().setNavigationMode(ActionBar.NAVIGATION_MODE_LIST);
    SpinnerAdapter mSpinnerAdapter = ArrayAdapter.createFromResource(this, R.array.planets_array,
          android.R.layout.simple_spinner_dropdown_item);

    getActionBar().setListNavigationCallbacks(mSpinnerAdapter , this);

Then

    @Override
public boolean onNavigationItemSelected(int arg0, long arg1) {
     Toast.makeText(getApplicationContext()," text",1000).show();
    return true;
}

Example:

public class MainActivity extends Activity implements ActionBar.OnNavigationListener {
    private DrawerLayout mDrawerLayout;
    private ListView mDrawerList;
    public ActionBarDrawerToggle mDrawerToggle;

    private CharSequence mDrawerTitle;
    private CharSequence mTitle;
    private String[] mPlanetTitles;
    ActionBar actionBar;

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

        actionBar = getActionBar();


        SpinnerAdapter mSpinnerAdapter = ArrayAdapter.createFromResource(this, R.array.planets_array,
                android.R.layout.simple_spinner_dropdown_item);
        actionBar.setDisplayShowTitleEnabled(false);
        actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_LIST);
        getActionBar().setListNavigationCallbacks(mSpinnerAdapter,this);

        //mTitle = mDrawerTitle = getTitle();
        mPlanetTitles = getResources().getStringArray(R.array.planets_array);
        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        mDrawerList = (ListView) findViewById(R.id.left_drawer);

       // mDrawerList.setBackgroundColor(Color.WHITE);
        // set a custom shadow that overlays the main content when the drawer opens
        mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
        // set up the drawer's list view with items and click listener

        mDrawerList.setAdapter(new ArrayAdapter<String>(this,
                R.layout.drawer_list_item, mPlanetTitles));

        mDrawerList.setOnItemClickListener(new DrawerItemClickListener());

        // enable ActionBar app icon to behave as action to toggle nav drawer
