我使用以下链接创建了导航抽屉，这非常好：

您可以从此URl下载导航抽屉 - https://github.com/sanjaisy/Android-Navigation-Drawer.git

现在我想在这个导航抽屉中添加子菜单。请帮我解决一下。

这是我的完整java代码

这是布局代码

public class SmoothBanlanceHome extends ActionBarActivity {

        private ListView mDrawerList;
        private DrawerLayout mDrawerLayout;
        private ArrayAdapter<String> mAdapter;
        private ActionBarDrawerToggle mDrawerToggle;
        private String mActivityTitle;

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

        mDrawerList = (ListView)findViewById(R.id.navList);mDrawerLayout = (DrawerLayout)findViewById(R.id.drawer_layout);
        mActivityTitle = getTitle().toString();

        addDrawerItems();
        setupDrawer();

        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setHomeButtonEnabled(true);
    }

        private void addDrawerItems() {
            String[] MenuArray = getResources().getStringArray(R.array.Naviagation_Menu_List);
            mAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, MenuArray);
            mDrawerList.setAdapter(mAdapter);

            mDrawerList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                @Override
                public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                    Toast.makeText(SmoothBanlanceHome.this, "Time for an upgrade!", Toast.LENGTH_SHORT).show();
                }
            });
        }

        private void setupDrawer() {
            mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.drawer_open, R.string.drawer_close) {

                /** Called when a drawer has settled in a completely open state. */
                public void onDrawerOpened(View drawerView) {
                    super.onDrawerOpened(drawerView);
                    getSupportActionBar().setTitle("Menu");
                    invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
                }

                /** Called when a drawer has settled in a completely closed state. */
                public void onDrawerClosed(View view) {
                    super.onDrawerClosed(view);
                    getSupportActionBar().setTitle(mActivityTitle);
                    invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
                }
            };

            mDrawerToggle.setDrawerIndicatorEnabled(true);
            mDrawerLayout.setDrawerListener(mDrawerToggle);
        }

        @Override
        protected void onPostCreate(Bundle savedInstanceState) {
            super.onPostCreate(savedInstanceState);
            // Sync the toggle state after onRestoreInstanceState has occurred.
            mDrawerToggle.syncState();
        }

        @Override
        public void onConfigurationChanged(Configuration newConfig) {
            super.onConfigurationChanged(newConfig);
            mDrawerToggle.onConfigurationChanged(newConfig);
        }}

请有人告诉我如何使用此代码制作子菜单。您也可以从我上面提到的git url下载完整的导航工作代码。

您应该使用Android支持设计库中的NavigationView而不是此NavigationDrawer。

查看此官方样本：

https://github.com/chrisbanes/cheesesquare

这很容易。

使用Android Suppor Design Library，您将创建如下的子菜单：

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <group android:checkableBehavior="single">
        <item
            android:id="@+id/nav_home"
            android:icon="@drawable/ic_event"
            android:title="Home" />
        <item
            android:id="@+id/nav_profile"
            android:icon="@drawable/ic_dashboard"
            android:title="Perfil" />
    </group>

    <item android:title="More Options">
        <menu>
            <item
                android:icon="@drawable/ic_forum"
                android:title="Forum" />
            <item
                android:icon="@drawable/ic_headset"
                android:title="Headset" />
        </menu>
    </item>
</menu>

祝你好运。
