问题描述

Android 中可以有子菜单吗?

你在 Android 中怎么称呼这个视图?

解决方案

这是一个示例代码

在抽屉布局中,使用一个简单的 ExpandableListView 并对其进行自定义.

通过扩展 BaseExpandableListAdapter 来制作自定义适配器

public class NavAdapter extends BaseExpandableListAdapter{...}

并将 drawerList(ExpandableListView 对象)附加到 ActionBarToggle

actionBarDrawerToggle = new ActionBarDrawerToggle(this,drawer,toolbar,R.string.drawer_open,R.string.drawer_close )

Is having a sub menu possible in Android?

And what do you call this view in Android?

解决方案

Here is a sample code for this https://github.com/D8thReaper/android-navigation-menu-expandable. The sample is in material design and is pretty simple to use.

In the drawer layout, use a simple ExpandableListView and customize it.

<ExpandableListView
android:id="@+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:dividerHeight="1dp"
android:divider="@color/list_divider"
android:listSelector="@drawable/list_selector"
android:background="@color/list_background" />

Make a custom adapter by extending with BaseExpandableListAdapter

public class NavAdapter extends BaseExpandableListAdapter{...}

And attach the drawerList (ExpandableListView object) to ActionBarToggle

actionBarDrawerToggle = new ActionBarDrawerToggle(this,drawer,toolbar,R.string.drawer_open,R.string.drawer_close )
