Create rounded corners on View

Question

Is there any way to create rounded corners of a View inside the LinearLayout instead of using shape ?

<View
 android:layout_width="48dp"
 android:clickable="true"
 android:layout_height="48dp"
 android:background="#f55151" />

Answer 1

You can use a CardView and inside the cardview you can make your own views. On the CardView you can set the card_view:cardCornerRadius.

<androidx.cardview.widget.CardView
   xmlns:card_view="http://schemas.android.com/apk/res-auto"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   card_view:cardBackgroundColor="@color/yourColor"
   card_view:cardCornerRadius="6dp">

   <View
      android:layout_width="48dp"
      android:clickable="true"
      android:layout_height="48dp"
      android:background="#f55151" />

</androidx.cardview.widget.CardView>

If you don`t want to use shape CardView is the easiest way: for more detail look at the official docs

first add this line to your dependencies:

implementation 'com.android.support:cardview-v7:28.0.0'

then use it like this:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:card_view="http://schemas.android.com/apk/res-auto"
    ... >
    <!-- A CardView that contains a TextView -->
    <android.support.v7.widget.CardView
        xmlns:card_view="http://schemas.android.com/apk/res-auto"
        android:id="@+id/card_view"
        android:layout_gravity="center"
        android:layout_width="200dp"
        android:layout_height="200dp"
        card_view:cardCornerRadius="4dp">

        <TextView
            android:id="@+id/info_text"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </android.support.v7.widget.CardView>
</LinearLayout>

You can find more options here like: corner radius, elevation, background color and so on.
