Android 如何组合导航抽屉和微调器[如在谷歌应用程序中]

我需要你的建议。在Android的Google+应用程序中，有两个元素，我不知道如何组合。一个是“”，第二个是“”。你知道这两种元素是如何组合在一起的吗

非常感谢你的建议！ 另外，我知道，我跛脚了：）（我为我的英语道歉）

将微调器添加到导航栏

启用下拉导航的基本步骤是：

1.创建一个SpinnerAdapter，提供下拉列表的可选项列表，以及在列表中绘制每个项时要使用的布局

2.实现ActionBar.OnNavigationListener以定义用户从列表中选择项目时发生的行为

3.在活动的onCreate（）方法中，通过调用setNavigationMode（NAVIGATION_MODE_list）启用操作栏的下拉列表

4.使用setListNavigationCallbacks（）设置下拉列表的回调

检查主题添加下拉导航

例如：

    public class MainActivity extends Activity implements OnNavigationListener

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
        getActionBar().setDisplayHomeAsUpEnabled(true);
        getActionBar().setHomeButtonEnabled(true);

        // ActionBarDrawerToggle ties together the the proper interactions
        // between the sliding drawer and the action bar app icon
        mDrawerToggle = new ActionBarDrawerToggle(

         this as a sliding drawer on the left side for left-to-right
         languages and on the right side for right-to-left languages.

         the container. A solid background is used for contrast
         with the content view. -->
