AndroidApp侧边栏菜单的简单实现
效果图
Layout
注意事项
想要实现侧边栏，需要配合使⽤DrawerLayout。因为会⽤到嵌套布局，所以根布局不能是 ConstraintLayout，最好使⽤ LinearLayout 布局。DrawerLayout 布局下再嵌套两个布局，⼀个放置内容如 LinearLayout，⼀个放置侧划菜单，这⾥使⽤ NavigationView
为了出现侧边栏点击图标和菜单图标，需要⾃定义⼀个 ToolBar，放置在内容 Layout ⾥
重点
侧划菜单 NavigationView ⼀定要设置 android:layout_gravity="start"
humidity实例
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="/apk/res/android"
xmlns:tools="/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
reluctanttools:context=".ebook.EbookActivity">
<androidx.drawerlayout.widget.DrawerLayout
android:id="@+id/drawer_ebook"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">千人成本
<LinearLayout

android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<androidx.appcompat.widget.Toolbar
android:id="@+id/main_menu_ebook"
android:layout_width="match_parent"

android:layout_height="wrap_content"
app:navigationIcon="@mipmap/menu_more" />
<TextView
android:id="@+id/bookContent"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
&le.android.material.navigation.NavigationView
android:id="@+id/navigation_ebook"
android:layout_width="230dp"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="@layout/navigation_ebook_header"
app:menu="@menu/menu_drawer_ebook"/>
</androidx.drawerlayout.widget.DrawerLayout>
</LinearLayout>
上⾯不能加注释，有⼀点想特别说明⼀下，因为搞了好久，就是那个menu的三横图标怎么弄出来，开始⼀直在navigation上找，⾏不能，最后看到说toolbar本⾝可以设定，尝试⼀下确实ok
⾃已找的喜欢的图标
app:navigationIcon="@mipmap/menu_more"
Activity
绑定侧划监听事件
private lateinit var mBinding: ActivityEbookBinding
private lateinit var mDrawerToggle: ActionBarDrawerToggle
override fun onCreate(savedInstanceState: Bundle?) {
mBinding = ActivityEbookBinding.inflate(layoutInflater)
)
tSupportActionBar(mBinding.mainMenuEbook)
initialData()
}
private fun initialData(){
争先创优//初使化侧边栏监听事件
mDrawerToggle = ActionBarDrawerToggle(this, mBinding.drawerEbook, mBinding.mainMenuEbook, R.string.openDrawerContentDesc, R.string.cloDrawerContentDesc) mDrawerToggle.syncState()
//绑定侧边栏监听事件
mBinding.drawerEbook.addDrawerListener(mDrawerToggle)

//侧边栏菜单图标颜⾊恢复正常，⽽⾮默认的灰⾊
mBinding.navigationEbook.itemIconTintList = null
//绑定侧边栏菜单点击事件
mBinding.navigationEbook.tNavigationItemSelectedListener { item: MenuItem ->
when(item.itemId){
u_drawer_ebook_tting -> showSnackBar(mBinding.navigationEbook,"menu_drawer_tting")
retire
u_drawer_ebook_clo -> finish()
}
true
}
}
