How can I apply a shadow effect to a <View> element just like a regular tab bar?

My customized navigation bar is using the <View> element.

Is it possible to add a bottom shadow similar to the default react-navigation bar (refer to the image below)?

I find it challenging to implement the shadow effect

  header: {
    height: 55,
    flexDirection: 'row',
    shadowColor: 'black',
    shadowOpacity: 0.1,
    shadowRadius: 5,
    shadowOffset: {
      height: 5,
    },
    elevation: 4,
    zIndex: -1,
    overflow: 'visible'
  },

Answer №1

To achieve the desired effect, you can easily implement CSS:

nav: {
    height: 60,
    display: 'flex',
    alignItems: 'center',
    justifyContent: 'space-between',
    boxShadow: '0 2px 4px rgba(0,0,0,0.2)',
    borderRadius: 5
}

Feel free to customize the values as needed. Don't forget to set a suitable zIndex value and ensure that the overflow property of your navigation bar is set to visible when necessary.

Answer №2

Shadow is not appearing because the width attribute is missing in the shadowOffset property.

shadowOffset: {
    height: 2,
    width: 2 
}
