BottomNavigationView始终显示图标和文本标签 [英] BottomNavigationView display both icons and text labels at all times

问题描述

我正在使用设计支持库版本25中的android.support.design.widget.BottomNavigationView

I am using android.support.design.widget.BottomNavigationView from design support library version 25

compile 'com.android.support:design:25.0.0'

<android.support.design.widget.BottomNavigationView
        android:id="@+id/bottomBar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_gravity="center"
        app:itemBackground="@color/colorPrimary"
        app:menu="@menu/bottom_navigation_main"
        android:forceHasOverlappingRendering="true"/>

@ menu / bottom_navigation_main中只有三个操作时，它同时显示图标和文本标签

When there are only three actions in @menu/bottom_navigation_main, it displays both icons and text labels at all times.

当动作多于三个时，始终显示图标和文本标签的方式是什么。

What is the way to display both icons and text labels at all the time when there are more than three actions.

推荐答案

对于仍在寻找解决方案且不希望依赖第三方库或运行时反射的任何人，支持库28 / Jetpack中的BottomNavigationView本机支持始终具有文本标签。

For anyone still looking for a solution and doesn't want to rely on third party libraries or runtime reflection, BottomNavigationView in Support Library 28/Jetpack natively supports always having text label.

这是您要寻找的方法。

This is the method you're looking for.

或者在XML中， app：labelVisibilityMode = labeled
