我正在向项目添加BottomNavigationView,并且希望每个底部标签具有不同的背景颜色。在颜色选择器资源文件中使用android:state_selected="true"
使用其他颜色似乎无效我也尝试输入更多类似android:state_focused =“ true”或android:state_enabled =“ true”之类的东西,不幸的是没有任何效果。
(BottomnavigationView)
<android.support.design.widget.BottomNavigationView
android:id="@+id/bottomNavigationView"
android:layout_width="0dp"
android:layout_height="wrap_content"
app:itemIconTint="@color/menu_txt_color"
app:itemTextColor="@color/menu_txt_color"
android:background="@drawable/bnv_tab_item_foreground"
app:layout_constraintBottom_toTopOf="@+id/guideline14"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="1.0"
app:layout_constraintStart_toStartOf="parent"
app:menu="@menu/navigation" />
(颜色选择器)
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@color/add_child" android:state_checked="true" android:state_pressed="true"/>
<item android:drawable="@color/light_blue" android:state_checked="false"/>
</selector>
(我的菜单资源)
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="@+id/tab1"
android:layout_height="wrap_content"
android:icon="@drawable/baby3"
android:checked="true"
android:title="hello"
app:showAsAction="always|withText" />
<item
android:id="@+id/tab2"
android:icon="@drawable/baby2"
android:title="heelo2"
app:showAsAction="always|withText|collapseActionView" />
<item
android:id="@+id/tab3"
android:checkable="false"
android:icon="@drawable/baby2"
android:title="hello 3"
app:showAsAction="always|withText" />
<item
android:id="@+id/tab4"
android:checkable="false"
android:icon="@drawable/baby3"
android:title="heelo 4"
app:showAsAction="always|withText" />
</menu>
选择后突出显示选项卡,我想要Instagram之类的BottomNavigationBar选项卡,我也尝试过(live),但没有帮助。.
有人遇到过这种情况吗?
谢谢

尝试这种方式
使用“自定义操作”布局作为菜单
$Array = @()
$Computers = "Computer1","Computer2","Computer3"
Foreach ($Computer in $Computers)
{
$Services = Get-WmiObject Win32_Service -ComputerName $Computer | Select name,state,startmode
Foreach ($Service in $Services)
{
$Array += $Service
}
}
$Array | Format-Table
<item
android:id="@+id/nav_1"
android:title=""
app:actionLayout="@layout/custom_layout"/>
<item
android:id="@+id/nav_2"
android:title=""
app:actionLayout="@layout/custom_layout"/>
<item
android:id="@+id/nav_3"
android:title=""
app:actionLayout="@layout/custom_layout"/>
<item
android:id="@+id/nav_4"
android:title=""
app:actionLayout="@layout/custom_layout"/>
<item
android:id="@+id/nav_5"
android:title=""
app:actionLayout="@layout/custom_layout"/>
在custom_layout
文件夹中将是这样
layout
在使用<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<Button
android:id="@+id/button"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_gravity="center_vertical"
android:background="@drawable/selector"
android:layout_weight="1"
android:gravity="center_vertical"/>
</LinearLayout>
的“活动”中,您可以这样做
BottomNavigationView
更新
selector.xml
try{
View view = navigationView.getMenu().findItem(R.id.nav_1).getActionView();
Button button = (Button) view.findViewById(R.id.button);
//button.setOnClickListener(this);
// similarly for others menu in BottomNavigationView
} catch (Exception e) {
AppLogger.getInstance().writeException(e);
}
