java-如何在cardview侧面设置颜色

我试图了解像这样在CardView侧面设置颜色的最佳方法是什么

我的cardview看起来像这样：

<?xml version="1.0" encoding="utf-8"?>
<androidx.cardview.widget.CardView 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/tools"
android:id="@+id/cardViewWe"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="4dp"
android:layout_marginTop="4dp"
android:layout_marginRight="4dp"
android:layout_marginBottom="4dp"
android:foreground="?attr/selectableItemBackground"
android:transitionName="cardTransition"
app:cardBackgroundColor="@drawable/selector"
app:cardElevation="2dp"

card_view:cardCornerRadius="8dp">

  <androidx.constraintlayout.widget.ConstraintLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">
 .....
 .....
   </androidx.constraintlayout.widget.ConstraintLayout>
</androidx.cardview.widget.CardView>

解决方法:

试试这个

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    app:cardCornerRadius="10dp"
    app:cardElevation="2dp"
    app:cardUseCompatPadding="true">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@android:color/white"
        android:orientation="horizontal">

        <View
            android:layout_width="5dp"
            android:layout_height="match_parent"
            android:background="@color/colorAccent" />

        <LinearLayout
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:orientation="vertical"
            android:padding="10dp">

            <TextView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:text="Nilesh Rathod" />

            <TextView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:text="Nilesh Rathod" />

            <TextView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:text="Nilesh Rathod" />

        </LinearLayout>
    </LinearLayout>


</android.support.v7.widget.CardView>
