A CardView is an android widget which is an extension of FrameLayout which can have rounded corners and shadows. It can wrap the other elements like TextView ,ImageView etc. into a single card which will give beautiful look and feel. In this tutorial we see an example for CardView in android. For using CardView in your application you need to compile the following library in your graddle.
compile 'com.android.support:cardview-v7:23.1.1'
Following is the code to be added to your layout for implementing CardView
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:cardElevation="2dp"
app:cardUseCompatPadding="true"></android.support.v7.widget.CardView>
Now you can simply add the layout which you want to display inside the CardView, Here am using a LinearLayout which is containing one TextView and ImagView.
<android.support.v7.widget.CardView
android:id="@+id/card_view"
android:layout_width="fill_parent"
android:layout_height="100dp"
android:layout_gravity="center"
android:layout_margin="5dp"
card_view:cardCornerRadius="2dp"
card_view:contentPadding="10dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<ImageView
android:id="@+id/im_language"
android:layout_width="60dp"
android:layout_height="60dp"
android:src="@mipmap/ic_launcher" />
<TextView
android:id="@+id/tv_language"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:text="Title comes here" />
</LinearLayout>
</android.support.v7.widget.CardView>
Now Simply Run the project you will get an output of card which contains an image and title.
