            android:layout_height="match_parent" />
    </android.support.v7.widget.CardView>
</LinearLayout>

This is my preview

It shows only in the Android studio preview. Did you try running your code on a device or an emulator? — Binary Baba, Mar 31 '19 at 02:52
Probably you are having some other issue. Can you check logs (logcat), and see what exception is getting thrown after your app crashes? — Binary Baba, Mar 31 '19 at 07:59
