将导航菜单移至顶部,操作栏下方 Android / XML
Move navigation menu to the top, below action bar Android / XML
你好 Whosebug!
我正在设计一个 android 应用程序,如下图所示:
Screenshot of Application run test
I cannot embed photos yet, please check the link
我有一个 navigation menu
卡在屏幕底部,我想将这个 navigation bar
移到顶部,under action bar
有 Home 标题.
我是 Android 的新手,感谢 full-way-to-solution 的简单回复!
底部导航菜单XML:
<item
android:id="@+id/navigation_home"
android:icon="@drawable/ic_action_remote"
android:title="@string/title_home" />
<item
android:id="@+id/navigation_tools"
android:icon="@drawable/ic_tools_24"
android:title="@string/title_Tools" />
<item
android:id="@+id/navigation_dashboard"
android:icon="@drawable/ic_dashboard_black_24dp"
android:title="@string/title_dashboard" />
<item
android:id="@+id/navigation_notifications"
android:icon="@drawable/ic_notifications_black_24dp"
android:title="@string/title_notifications" />
主要Activity:
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingTop="?attr/actionBarSize">
<com.google.android.material.bottomnavigation.BottomNavigationView

app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:menu="@menu/bottom_nav_menu" />
<fragment
android:id="@+id/nav_host_fragment_activity_main"
android:name="androidx.navigation.fragment.NavHostFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:defaultNavHost="true"

app:layout_constraintHorizontal_bias="0.0"
app:layout_constraintLeft_toLeftOf="parent"

app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="1.0"
app:navGraph="@navigation/mobile_navigation" />
</androidx.constraintlayout.widget.ConstraintLayout>
我发现这个文件太像移动导航了:
<?xml version="1.0" encoding="utf-8"?>

在您的主 activity XML 中,在您的导航栏中,更改
app:layout_constraintBottom_toBottomOf="parent"
到
app:layout_constraintTop_toTopOf="parent"
