Question

我希望像google示例中那样创建一个迷你抽屉菜单：

mini-drawer menu

我曾尝试创建一个始终保留在ParentLeft上的布局，并在打开时将菜单溢出，但看起来并不自然。有谁知道我该怎么做？

更新

我尝试过另一种方式。要听菜单滑动，并在它足够关闭时捕捉，我可以设置菜单大小，并保持图标可见，但文本消失。

@Override
        public void onDrawerSlide(float v, int i) {
            Log.d("onDrawerSlide", "v=" + v + " i=" + i);
            if (i<previewsI && decreasingCount > 3) {
                // check if menu is closed enough
                if (i <100 && i > 50) {
                    // change menu size, and force menu to keep opened
                    mDrawer.setMenuSize(Utils.dpToPx(70, getApplicationContext()));
                    mDrawer.openMenu();
                    // TODO: hide menu items title, and let only icons to be visible

                }
            }
            else if (i < previewsI)
                // make sure the menu is closing
                    decreasingCount++;

            previewsI = i;
        }

它有效，但不如我希望的那么顺畅。现在我不得不再次顺利打开它。无论如何，我不认为这是一个优雅的解决方案。我相信那里一定有更好的。

我知道这是一个非常古老的问题，我不确定你是否愿意使用图书馆。但MaterialDrawer库将提供 MiniDrawer 实现，包括转换为普通抽屉。

如屏幕截图所示， MiniDrawer 也支持徽章，并且还附带 AccountSwitcher 。还有其他一切。

MiniDrawer 使用允许交叉渐变效果的Crossfader库。 交叉渐变器库的sample application也会显示如何使用 MaterialDrawer

实现此功能

以下是创建所示示例的代码（您也可以在repository on GitHub找到它）：

DrawerBuilder builder = new DrawerBuilder()
        .withActivity(this)
        .withToolbar(toolbar)
        .withInnerShadow(true)
        .addDrawerItems(
                //.. add some items ..
        ) // add the items we want to use with our Drawer
        .withOnDrawerItemClickListener(new Drawer.OnDrawerItemClickListener() {
            @Override
            public boolean onItemClick(View view, int position, IDrawerItem drawerItem) {
                //some actions inside the listener

                return miniResult.onItemClick(drawerItem);
            }
        })
        .withSavedInstance(savedInstanceState);

// build the main drawer
result = builder.buildView();
// build the miniDrawer
miniResult = new MiniDrawer().withDrawer(result).withInnerShadow(true).withAccountHeader(headerResult);

//define the width of the normal drawer, and the minidrawer
int first = (int) UIUtils.convertDpToPixel(300, this);
int second = (int) UIUtils.convertDpToPixel(72, this);

//create the Crossfader used to hook the MiniDrawer and the normal drawer together. This also handles the crossfade effect.
crossFader = new Crossfader()
        .withContent(findViewById(R.id.crossfade_content))
        .withFirst(result.getSlider(), first)
        .withSecond(miniResult.build(this), second)
        .withSavedInstance(savedInstanceState)
        .build();

// inform the MiniDrawer about the crossfader.
miniResult.withCrossFader(new CrossfadeWrapper(crossFader));

我想出了一种使用SlidingPaneLayout实现迷你导航抽屉的方法。

创建布局资源文件并将SlidingPaneLayout设置为父视图。 SlidingPaneLayout需要两个子视图：主视图和详细视图。主视图将包含所有菜单选项的列表，详细视图将包含内容。

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.SlidingPaneLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <!--Master fragment-->
    <fragment
        android:name="com.ng.anthony.mininavigationdrawer.MasterFragment"
        android:layout_width="220dp"
        android:layout_height="match_parent"
        android:id="@+id/fragment_master">
    </fragment>

    <!--Detail layout -->
    <FrameLayout
        android:layout_width="1000dp"
        android:layout_height="match_parent"
        android:layout_marginLeft="56dp">
    </FrameLayout>
</android.support.v4.widget.SlidingPaneLayout>

创建主分段类。在主片段中，您应该有一个包含所有菜单选项的列表视图。

public class MasterFragment extends ListFragment {

    public View onCreateView (LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_master, container);

        setListAdapter(new MenuListAdapter(R.layout.row_menu_action_item, getActivity(), MenuActionItem.values()));
        return view;
    }
}

将主片段布局添加到布局资源文件夹

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ListView
        android:id="@android:id/list"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@android:color/darker_gray"
        android:divider="@null">
    </ListView>

</LinearLayout>

主片段包含一个列表视图，并使用菜单选项的枚举来填充列表。

public enum MenuActionItem {
    ITEM1,
    ITEM2,
    ITEM3,
    ITEM4,
    ITEM5
}

主片段还包含一个显示菜单选项列表的自定义数组适配器。自定义数组适配器为每个菜单选项的行布局充气。

import android.app.Activity;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;

import java.util.ArrayList;

/**

 */
public class MenuListAdapter extends ArrayAdapter<MenuActionItem> {

    int resource;
    Activity activity;

    public MenuListAdapter(int resource, Activity activity, MenuActionItem[] items) {
        super(activity, resource, items);

        this.resource = resource;
        this.activity = activity;
    }

    public View getView (int position, View convertView, ViewGroup parent) {
        View rowView = convertView;

        if(rowView == null) {
            rowView = activity.getLayoutInflater().inflate(resource, null);

            MenuItemViewHolder viewHolder = new MenuItemViewHolder();

            viewHolder.menuItemImageView = (ImageView)rowView.findViewById(R.id.menu_item_image_view);
            viewHolder.menuItemTextView = (TextView)rowView.findViewById(R.id.menu_item_text_view);

            rowView.setTag(viewHolder);
        }

        MenuItemViewHolder holder = (MenuItemViewHolder)rowView.getTag();

        if(position == MenuActionItem.ITEM1.ordinal()) {
            holder.menuItemImageView.setImageDrawable(activity.getDrawable(R.drawable.ic_payment_white_24dp));
            holder.menuItemTextView.setText(activity.getResources().getString(R.string.item1));
        }
        else if(position == MenuActionItem.ITEM2.ordinal()) {
            holder.menuItemImageView.setImageDrawable(activity.getDrawable(R.drawable.ic_pets_white_24dp));
            holder.menuItemTextView.setText(activity.getResources().getString(R.string.item2));
        }
        else if(position == MenuActionItem.ITEM3.ordinal()) {
            holder.menuItemImageView.setImageDrawable(activity.getDrawable(R.drawable.ic_receipt_white_24dp));
            holder.menuItemTextView.setText(activity.getResources().getString(R.string.item3));
        }
        else if(position == MenuActionItem.ITEM4.ordinal()) {
            holder.menuItemImageView.setImageDrawable(activity.getDrawable(R.drawable.ic_shopping_cart_white_24dp));
            holder.menuItemTextView.setText(activity.getResources().getString(R.string.item4));
        }
        else if(position == MenuActionItem.ITEM5.ordinal()) {
            holder.menuItemImageView.setImageDrawable(activity.getDrawable(R.drawable.ic_work_white_24dp));
            holder.menuItemTextView.setText(activity.getResources().getString(R.string.item5));
        }

        return rowView;
    }

    private static class MenuItemViewHolder {
        public ImageView menuItemImageView;
        public TextView menuItemTextView;
    }
}

添加行布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal" android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="16dp"
    android:gravity="center_vertical">

    <ImageView
        android:id="@+id/menu_item_image_view"
        android:layout_width="24dp"
        android:layout_height="24dp"
        android:layout_marginRight="16dp"/>

    <TextView
        android:id="@+id/menu_item_text_view"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="16sp"
        android:textColor="@android:color/white"/>

</LinearLayout>

最后你应该看到这样的东西
