如何从android.support.v4.widget.DrawerLayout的Material Design guide启用或伪造迷你变体？

Question

如何从" 材料设计"指南中启用"迷你变体" - 以便仅在其关闭状态下显示抽屉图标？

作为我的问题的简单测试项目,我采用了Google着名的导航抽屉示例 - 然后在右侧添加了第二个抽屉,并在两侧添加了ListView条目的图标:

请告知如何激活(或者假冒？)"迷你变体抽屉" - 以便在上面的屏幕截图的右侧只能看到音乐符号.

这是我的布局文件activity_main.xml:

<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">

    <LinearLayout 
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <android.support.v7.widget.Toolbar 
            xmlns:android="http://schemas.android.com/apk/res/android"
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

        <ImageView 
            android:src="@drawable/ic_music_note_black_24dp"
            android:onClick="openActions"
            android:layout_gravity="right"
            android:padding="16dp"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />

        </android.support.v7.widget.Toolbar>

        <FrameLayout
            android:id="@+id/content_frame"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

    </LinearLayout>

    <ListView
        android:id="@+id/left_drawer"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:choiceMode="singleChoice" />

    <ListView
        android:id="@+id/right_drawer"
        android:layout_width="160dp"
        android:layout_height="match_parent"
        android:layout_gravity="end"
        android:choiceMode="singleChoice" />

</android.support.v4.widget.DrawerLayout>

而MainActivity.java使用它:

public class MainActivity extends AppCompatActivity {
    private Toolbar mToolbar;
    private DrawerLayout mDrawerLayout;
    private ListView mDrawerList;
    private ListView mActionList;
    private ActionBarDrawerToggle mDrawerToggle;

    private String[] mPlanetTitles;
    private String[] mActions;
    private int[] mIcons;

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

        mPlanetTitles = getResources().getStringArray(R.array.planets_array);
        mActions = getResources().getStringArray(R.array.music_actions);

        TypedArray ta = getResources().obtainTypedArray(R.array.music_icons);
        mIcons = new int[ta.length()];
        for (int i = 0; i < mIcons.length; i++)
            mIcons[i] = ta.getResourceId(i, R.drawable.ic_menu_black_24dp);
        ta.recycle();

        mToolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(mToolbar);

        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        mDrawerList = (ListView) findViewById(R.id.left_drawer);
        mActionList = (ListView) findViewById(R.id.right_drawer);

        mDrawerList.setAdapter(new ArrayAdapter<String>(this,
            R.layout.drawer_list_item, mPlanetTitles) {
            @Override
            public View getView(int position, View convertView, ViewGroup parent) {
                TextView view = (TextView) super.getView(position, convertView, parent);
                view.setCompoundDrawablePadding(24);
                view.setCompoundDrawablesWithIntrinsicBounds(
                    R.drawable.ic_stars_white_24dp, 0, 0, 0);
                return view;
            }
        });

        mActionList.setAdapter(new ArrayAdapter<String>(this,
            android.R.layout.simple_list_item_1, mActions) {
            @Override
            public View getView(int position, View convertView, ViewGroup parent) {
                TextView view = (TextView) super.getView(position, convertView, parent);
                view.setCompoundDrawablePadding(24);
                view.setCompoundDrawablesWithIntrinsicBounds(mIcons[position], 0, 0, 0);
                return view;
            }
        });

        mDrawerToggle = new ActionBarDrawerToggle(
                this,                  /* host Activity */
                mDrawerLayout,         /* DrawerLayout object */
                mToolbar,
                R.string.drawer_open,  /* "open drawer" description for accessibility */
                R.string.drawer_close  /* "close drawer" description for accessibility */
                ) {
            public void onDrawerClosed(View view) {
                mToolbar.setTitle(mTitle);
                invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
            }

            public void onDrawerOpened(View drawerView) {
                mToolbar.setTitle(mDrawerTitle);
                invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
            }
        };
        mDrawerLayout.setDrawerListener(mDrawerToggle);

        if (savedInstanceState == null) {
            selectItem(0);
        }
    }

官方的NavigationDrawer确实在他们的设计规范中提到了"mini-variant" ,但没有关于如何使用它的文档.也许它稍后会作为支持库的一部分出现.如果/何时有官方解决方案,将更新答案.

直到,看看ActionsContentView库,完全按照你的意愿行事.上次更新是2年前,但它确实有效,我前一段时间使用过它.您也可以在Google Play上获取并测试它.
