How to set background color of view transparent in React Native

Question

This is the style of the view that i have used

backCover: {
  position: 'absolute',
  marginTop: 20,
  top: 0,
  bottom: 0,
  left: 0,
  right: 0,
}

Currently it has a white background. I can change the backgroundColor as i want like '#343434' but it accepts only max 6 hexvalue for color so I cannot give opacity on that like '#00ffffff'. I tried using opacity like this

backCover: {
  position: 'absolute',
  marginTop: 20,
  top: 0,
  bottom: 0,
  left: 0,
  right: 0,
  opacity: 0.5,
}

but it reduces visibility of view's content. So any answers?

Answer 1

Use rgba value for the backgroundColor.

For example,

backgroundColor: 'rgba(52, 52, 52, 0.8)'

This sets it to a grey color with 80% opacity, which is derived from the opacity decimal, 0.8. This value can be anything from 0.0 to 1.0.
