Android support card view V7 framework (CardView) is a supporting library that provides card -type interface display elements, which can easily add card design styles to the application.The framework is provided in Android Support Library and supports it in the version before Android 5.0. The card view V7 framework provides a view container called CardView, which can be used to package other view elements, and presented on the user interface as a card.It can be used to replace traditional layout containers, such as Framelayout or RelativeLayout, and add a more beautiful and modern appearance to the application.Card views are often used to display pictures in list items, content cards or albums. The following is an example of using a card view V7 framework: 1. First, make sure that the card view V7 framework has been added to the application dependencies.Add the following code to the BUILD.GRADLE file of the app: groovy dependencies { implementation 'com.android.support:appcompat-v7:<version>' implementation 'com.android.support:cardview-v7:<version>' } 2. Define CardView in the layout file, for example: <android.support.v7.widget.CardView android:layout_width="match_parent" android:layout_height="wrap_content" app:cardCornerRadius="8dp" app:cardElevation="4dp"> <!-Other view elements-> </android.support.v7.widget.CardView> 3. Add other view elements to CardView, such as TextView, ImageView or other layout containers. <android.support.v7.widget.CardView ... > <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:padding="16dp" android:orientation="vertical"> <ImageView android:layout_width="80dp" android:layout_height="80dp" android:src="@drawable/ic_image" /> <TextView android:layout_width="match_parent" android:layout_height="wrap_content" Android: text = "This is a card view example" /> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" Android: text = "button" /> </LinearLayout> </android.support.v7.widget.CardView> In the above example, we created a CardView to place an ImageView, a TextView and a Button in a linearlayout.CardView's rounded and shadow effects are set through the `App: CardCornerradius` and` App: Cardelevation 'attribute settings.
