[android] cardview 안될 때

cardview 그림자나 Radius 둥글게 적용이 안될 경우!

 

1. 라이브러리를 잘못 설치한 경우

 

implementation "androidx.cardview:cardview:1.0.0"

 

2. xml안에 설정을 잘못한 경우

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:card_view="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

다른 건 다 필요없이 xmls:card_view="http://schemas.android.com/apk/res-auto"를 기재해야한다.
