unsupportedoperationExceptionFailed to resolve attribute at index 3:TypedValueft

最近在用TabLayout实现数字小红点时，在调用orCreateBadge方法时

mDataBind.tabLayout.getTabAt(mViewModel.defaultSelectPos)?.let {
    it.orCreateBadge.apply {
        backgroundColor = ContextCompat.getColor(this@OrderActivity, R.color.red_FF)
        maxCharacterCount = 3
        number = mViewModel.addDishNumArray[mViewModel.defaultSelectPos]
        badgeTextColor = ContextCompat.getColor(this@OrderActivity, R.color.white)
    }
}

报了一个错：

仔细看报错原因是因为无法解析某个属性而导致的报错，一刚开始以为是gradle或者material库的版本问题导致的，酷酷一顿改，结果改了个寂寞。实际原因是在使用material的某些属性或api时一定要配套使用他们推荐的主题，否则就会报错。

解决办法：将AndroidManifest.xml文件中的主题样式改成MaterialComponents主题中的其中某个样式就行。如：将android:theme="@style/Theme.AppCompat.Light.NoActionBar"改成android:theme="@style/Theme.MaterialComponents.Light.NoActionBar"，就能正常运行了。
