Düzende iki kart varsa, ikinci kartın altında gölge/yükseklik yok. Niye ya?

Question

Tek bir RelativeLayout numaralı belgede 2 cards var. Sorun, ikinci kartın altında hiçbir yükseklik veya gölge olmamasıdır.

burada ekran görüntüsüne bakın:

    </LinearLayout> 

</RelativeLayout> 

bana bunlar oluyor neden bildirin ve nasıl altına gölge/irtifa sahip olabilir: Burada screenshot

ben xml dosyasında yapmış ne ikinci kart da mı?

Answer 1

LinearLayout'unuz, kartın alt kısmındaki gölgeyi keserek yüksekliğini sarar.

Ya LinearLayout'un altına bir miktar dolgu koyun ya da onu yüksekliğe göre eşleşecek şekilde ayarlayın.
