如何在 android 中增加底部导航视图的高度及其图标和文本大小？

Question

我正在使用

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

Android 底部导航视图及其高度是固定的，并显示带有小文本的小图标。我的问题是如何增加它们的尺寸？我试图通过样式更改 xml 文件中的大小...除了 textsize 属性.

之外的所有其他属性都有效

如果可以的话，我可以务实地做到这一点吗，那么请写一个代码

Answer 1

我找到了一个解决方案来覆盖 dimens.xml 文件中的一些维度值，它适用于文本大小，但图标仍然很小。这是我如何做到的。希望这段代码也能帮助其他人:-)

<!-- Overriding Default Bottom Navigation sizes-->
    <dimen name="design_bottom_navigation_text_size" tools:override="true">16sp</dimen>
    <dimen name="design_bottom_navigation_active_text_size" tools:override="true">20sp</dimen>
    <dimen name="design_bottom_navigation_height" tools:override="true">70dp</dimen>

Answer 3

您可以在 dimens.xml 中覆盖的底部导航的正确值如下所示

design_bottom_navigation_active_item_max_width
design_bottom_navigation_active_text_size
design_bottom_navigation_elevation
design_bottom_navigation_height
design_bottom_navigation_item_max_width
design_bottom_navigation_item_min_width
design_bottom_navigation_margin
design_bottom_navigation_shadow_height
design_bottom_navigation_text_size
design_bottom_navigation_item_background
design_bottom_navigation_item
design_bottom_navigation_shadow_color

我尝试设置@Kobus Pitzer 列表的许多值，但在 dimens.xml 中，覆盖模式不起作用。它们可能是可以被代码而不是 dimens.xml

覆盖的值

这是默认值

<dimen name="design_bottom_navigation_active_item_max_width">168dp</dimen>
<dimen name="design_bottom_navigation_active_item_min_width">96dp</dimen>
<dimen name="design_bottom_navigation_active_text_size">14sp</dimen>
<dimen name="design_bottom_navigation_elevation">8dp</dimen>
<dimen name="design_bottom_navigation_height">56dp</dimen>
<dimen name="design_bottom_navigation_icon_size">24dp</dimen>
<dimen name="design_bottom_navigation_item_max_width">96dp</dimen>
<dimen name="design_bottom_navigation_item_min_width">56dp</dimen>
<dimen name="design_bottom_navigation_margin">8dp</dimen>
<dimen name="design_bottom_navigation_shadow_height">1dp</dimen>
<dimen name="design_bottom_navigation_text_size">12sp</dimen>
<color name="design_bottom_navigation_shadow_color">#14000000</color>

我在 BottomNavigationView 上使用了 scaleX 和 scaleY，添加开始和结束填充以将底部栏图标调整到所需位置。解决不同屏幕尺寸的图标和文字尺寸问题。
