BottomNavigationView的自定义TextSize支持android

问题描述

我正在尝试从android支持库25.0.0更改BottomNavigationView的textSize

I am trying to change the textSize of BottomNavigationView from android support library 25.0.0

<android.support.design.widget.BottomNavigationView
        android:id="@+id/bottom_navigation_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:background="@color/colorPrimaryDark"
        android:foregroundTint="@color/colorAccent"
        app:itemIconTint="@android:color/white"
        app:itemTextColor="@android:color/white"
        app:layout_anchor="@id/lyt_container"
        app:layout_anchorGravity="bottom"
        app:itemTextAppearance="@style/TextStyleBNV"
        app:menu="@menu/nav_menu" />

<style name="TextStyleBNV">
        <item name="android:textSize">@dimen/twelve_sp</item>
        <item name="android:padding">0dp</item>
        <item name="textAllCaps">false</item>
    </style>

有什么我想念的吗?

推荐答案

不幸的是，BottomNavigationView的第一个版本存在很多限制.现在，您不能仅使用支持设计API来更改标题大小.因此，要在Google未实现此限制的情况下解决此限制，您可以执行以下操作:

Unfortunately this first version of BottomNavigationView came with a lot of limitations. And for now you can't change titles size just using the support design API. So to solve this limitation while google doesn't implement it, you can do:

在您的dimen.xml中，您可以输入:

In your dimen.xml you can put:

    <dimen name="design_bottom_navigation_text_size" tools:override="true">30sp</dimen>
    <dimen name="design_bottom_navigation_active_text_size" tools:override="true">30sp</dimen>

这样做，您将覆盖BottomNavigationView内部类使用的dimen的默认值.所以要小心.

Doing this you are overriding the default value of dimen that the internal classes of BottomNavigationView use. So be carreful.
