BottomNavigationView 项目的宽度不相等[重复]

Question

我正在使用 BottomNavigationView。似乎一切都很好，但我遇到的问题是物品的宽度不相等。

<android.support.design.widget.BottomNavigationView
        android:id="@+id/bottomBar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        android:background="@color/colorPrimary"
        android:layout_alignParentBottom="true"
        app:itemBackground="@color/colorPrimary"
        app:itemIconTint="@color/bottom_nav_color"
        app:itemTextColor="@color/bottom_nav_color"
        app:menu="@menu/bottombar_tabs_new"></android.support.design.widget.BottomNavigationView>

这是我的菜单文件。

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">

<item
    android:id="@+id/tab_home_check"
    android:icon="@drawable/ic_home"
    android:title="Home"
    />
<item
    android:id="@+id/tab_rides"
    android:icon="@drawable/ic_road"
    android:title="Rides"
     />
<item
    android:id="@+id/tab_payment"
    android:icon="@drawable/ic_payment"

    android:title="Payment"
     />
<item
    android:id="@+id/tab_profile"
    android:icon="@drawable/ic_profile"
    android:title="Profile"
     />
<item
    android:id="@+id/tab_support"
    android:icon="@drawable/ic_support"
    android:title="Support"
     />
</menu>

这就是我得到的结果。

非常感谢您的高级帮助！

使用这条线

app:labelVisibilityMode="labeled"

Answer 2

移除移位模式

@SuppressLint("RestrictedApi")
private fun removeShiftMode(view: BottomNavigationView) {
   val menuView = view.getChildAt(0) as BottomNavigationMenuView
   try {
   val shiftingMode = menuView.javaClass.getDeclaredField("mShiftingMode")
   shiftingMode.isAccessible = true
   shiftingMode.setBoolean(menuView, false)
   shiftingMode.isAccessible = false
   for (i in 0 until menuView.childCount) {
     val item = menuView.getChildAt(i) as BottomNavigationItemView
     item.setShiftingMode(false)
     item.setChecked(item.itemData.isChecked)
   }
   } catch (e: NoSuchFieldException) {
   Log.e("NoSuchFieldException", "Unable to get shift mode field")
   } catch (e: IllegalAccessException) {
   Log.e("IllegalAccessException", "Unable to change value of shift mode")
}

}
