我的android项目有一些svg图标.如何增加这些图标的笔画宽度.
一个图标xml例如:
<vector android:height="28dp" android:viewportHeight="58.365"
android:viewportWidth="58.365" android:width="28dp" xmlns:android="http://schemas.android.com/apk/res/android">

我想在我的 Android 项目中创建一个底部导航栏。这是导航栏中的 5 个项目（只是项目图标。没有任何项目的名称）。我想以某种方式制作它，以便在选择项目时将其放大一点并显示其名称。我怎样才能做到这一点？
PS - 我尝试使用其中有图像按钮的图像视图。一个未放大的图标 imagebutton 和相应的放大图标（+它的名称）imagebutton 重叠，设置一个可见和另一个不可见交替，但这是一个坏主意。代码有效，但布局非常糟糕和凌乱。
