使用BottomNavigationView而不是标签视图,并将您的视图寻呼机链接到:
https://developer.android.com/reference/android/support/design/widget/BottomNavigationView
layout resource file:
<android.support.design.widget.BottomNavigationView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/navigation"
android:layout_width="match_parent"
android:layout_height="56dp"
android:layout_gravity="start"
app:menu="@menu/my_navigation_items" />
res/menu/my_navigation_items.xml:
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/action_search"
android:title="@string/menu_search"
android:icon="@drawable/ic_search" />
<item android:id="@+id/action_settings"
android:title="@string/menu_settings"
android:icon="@drawable/ic_add" />
<item android:id="@+id/action_navigation"
android:title="@string/menu_navigation"
android:icon="@drawable/ic_action_navigation_menu" />
</menu>
