如何在android中增加底部导航视图高度及其图标和文本大小？

Question

我在用

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

Android底部导航视图及其高度已固定,并显示带有小文本的小图标.我的问题是如何增加他们的尺寸？我试图xml通过样式改变文件中的大小......所有其他属性都在工作,除了textsize属性.

如果是这样,我能否实际做到这一点,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文件中的某些维度值,它适用于文本大小,但图标仍然很小.我就是这样做的.希望这段代码也能帮助别人:-)

<!-- 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

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>

Answer 4

您可以在dimens.xml中覆盖的Bottom Navigation的正确值（如@RamshaS回答）如下

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中使用覆盖模式不起作用。它们可能是可以被代码而不是dimens.xml覆盖的值
