Here is my Full java Code

这是我的完整 Java 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);
        }}

Here is the layout code

这是布局代码

 <!-- A DrawerLayout is intended to be used as the top-level content view using match_parent for both width and height to consume the full space available. -->
<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <!-- As the main content view, the view below consumes the entire
         space available using match_parent in both dimensions. -->
    <FrameLayout
        android:id="@+id/content_frame"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <!-- android:layout_gravity="start" tells DrawerLayout to treat
         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 drawer is given a fixed width in dp and extends the full height of
         the container. A solid background is used for contrast
         with the content view. -->
    <ListView
        android:id="@+id/left_drawer"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:choiceMode="singleChoice"
        android:divider="@android:color/transparent"
        android:dividerHeight="0dp"
        android:background="#111"/>
</android.support.v4.widget.DrawerLayout>

Please can anyone tell me how can I make Sub menu with this code. You can also download the full Navigation Working code from git url as I have mention above.

请谁能告诉我如何使用此代码制作子菜单。您还可以从上面提到的 git url 下载完整的导航工作代码。

You should use NavigationView from Android Support Design Library instead of this NavigationDrawer.

您应该使用 Android Support Design Library 中的 NavigationView 而不是这个 NavigationDrawer。

Check this official sample:

检查此官方示例：

It's quite easier.

这很容易。

Using Android Suppor Design Library you will create your submenus like this:

使用 Android 支持设计库，您将创建如下子菜单：

<?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>

Best regards.

此致。
