我尝试在底部导航菜单的顶部创建一个带有FAB的布局,但菜单始终位于按钮上方。 :(
我的layout.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/container"
tools:context="com.example.mytest.money.MainActivity">
<android.support.v7.widget.CardView
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:id="@+id/card_view"
android:layout_width="match_parent"
android:layout_margin="10dp"
android:layout_height="110dp"
android:padding="15dp"
card_view:cardElevation="2dp"
card_view:cardCornerRadius="4dp">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="Test" />
</android.support.v7.widget.CardView>
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="@+id/bottom_navigation"
android:layout_alignParentTop="true"
android:foreground="@color/colorBackground">
</ScrollView>
<com.aurelhubert.ahbottomnavigation.AHBottomNavigation
android:id="@+id/bottom_navigation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:selectedBackgroundVisible="false"
android:layout_gravity="bottom" />
<android.support.design.widget.FloatingActionButton
android:id="@+id/create_gain_expense"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|center"
android:layout_margin="15dp"
android:layout_above="@id/bottom_navigation"
android:src="@drawable/ic_add_white_24dp"
app:fabSize="normal" />
</android.support.design.widget.CoordinatorLayout>

我该怎么做才能改变这个? :d

我想问题是,AHBottomNavigation
的{{1}}比elevation
高FloatingActionButton
,这就是它显示在FloatingActionButton
之上的原因。
FloatingActionButton
提升默认6dp
,elevation
的默认AHBottomNavigation
为8dp
(来自AHBottomNavigation
source)< / p>
尝试将更高elevation
设置为FloatingActionButton
:
<android.support.design.widget.FloatingActionButton
android:id="@+id/create_gain_expense"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|center"
android:layout_margin="15dp"
android:layout_above="@id/bottom_navigation"
android:src="@drawable/ic_add_white_24dp"
app:fabSize="normal"
app:elevation="12dp"
app:borderWidth="0dp" />
#。您也可以使用android.support.design.widget.BottomNavigationView
代替AHBottomNavigation
。
以下是应用结构的正交视图:
请参阅documentation。
希望这会有所帮助〜

试用此代码:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/container">
<android.support.v7.widget.CardView
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:id="@+id/card_view"
android:layout_width="match_parent"
android:layout_margin="10dp"
android:layout_height="110dp"
android:padding="15dp"
card_view:cardElevation="2dp"
card_view:cardCornerRadius="4dp">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="Test" />
</android.support.v7.widget.CardView>
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="@+id/bottom_navigation"
android:layout_alignParentTop="true"
android:foreground="@color/white">
</ScrollView>
<android.support.design.widget.BottomNavigationView
android:layout_width="match_parent"
android:layout_height="56dp"
android:layout_weight="1"
android:layout_gravity="bottom"
android:background="@color/green"
app:itemIconTint="@color/white"
app:itemTextColor="@color/white"
android:id="@+id/bottomnav"
app:menu="@menu/main">
</android.support.design.widget.BottomNavigationView>
<android.support.design.widget.FloatingActionButton
android:id="@+id/create_gain_expense"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|center"
android:layout_margin="15dp"
android:layout_above="@id/bottom_navigation"
android:src="@drawable/ic_add_black_24dp"
app:fabSize="normal"
app:elevation="12dp"
app:borderWidth="0dp" />
</android.support.design.widget.CoordinatorLayout>
您可以将此底部导航栏替换为您自己的。
