android - How to add colored border on cardview?

Question

I am new to Android and this is my first question here.

I am trying to add a colored vertical border at the beginning of the cardview. How can I achieve it on xml ? I tried adding it with empty textview but it is messing up the whole cardview itself. Please check the picture link posted below for example.

Colored Border on Cardview

activity_main.xml

<android.support.v7.widget.CardView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    card_view:contentPadding="16dp"
    card_view:cardElevation="2dp"
    card_view:cardCornerRadius="5dp">

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <TextView
            style="@style/Base.TextAppearance.AppCompat.Headline"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="Title" />

        <TextView
            style="@style/Base.TextAppearance.AppCompat.Body1"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="Content here" />

    </LinearLayout>

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

Many thanks

Start From the material design update, it support app:strokeColor and also app:strokeWidth. see more

to use material design update. add following code to build.gradle(:app)

dependencies {
    // ...
    implementation 'com.google.android.material:material:1.0.0'
    // ...
  }

and Change CardView to MaterialCardView
