🚧 BarrierTape

ℹ️ About

Barrier tape is a great way to get a user's attention or alert them when a feature of your app is unavailable. This library allows you to create a barrier tape of different colors and shapes. It can be used as a background for any View or as content of ImageView

🔧 Installation

Add the following dependency to your build.gradle file:

dependencies {
  implementation 'com.github.alexmedv:BarrierTape:1.0.0'
}

⚠️ Don't forget to add the JitPack maven repository to the list of repositories: maven { url "https://jitpack.io" }

🕹️ Playground

For a better understanding of the library's capabilities, there is a playground in the demo app. The user can change all the parameters in real time: color palettes, sizes, width of stripes, etc.

✨ Examples

The BarrierTapeDrawable can be used immediately after it is created without any additional setup. The result will be a rectangle with yellow and black lines

// create with default settings
imageView.background = BarrierTapeDrawable()

Now let's add some colors by replacing the default colors. You need at least two colors, the maximum number of colors is unlimited.
⚠️ Note that all parameter changes must be performed in the main thread

val barrierTape = BarrierTapeDrawable()
barrierTape.setColors(listOf(0xcf322e, 0xd7d4d5))
imageView.background = barrierTape

The width of the lines and their incline can be changed. All dimensions are specified in pixels.

val barrierTape = BarrierTapeDrawable().apply {
  setColors(listOf(0x000000, 0xECB537))
  stripeWidth = 80
  isReversed = true
}

You can round any corners of a shape independently of each other
⚠️ Can only be used for Shape.RECTANGLE

imageView.background = BarrierTapeDrawable().apply {
  setColors(listOf(0x408d57,0x47a157, 0x6dba5e, 0x8fcf61, 0x43b7ad, 0x489ad8, 0x3777bd, 0x2e6187, 0x9a3f40, 0xe03d3c, 0xf0892f, 0xf3c73d))
  stripeWidth = 90
  setRadius(topLeftRadius = 40F, topRightRadius = 40F, bottomLeftRadius = 0F, bottomRightRadius = 0F)
  // to set the same radius for all corners you can use setRadius(40F)
}

The barrier tape can be drawn in any of five shapes: RECTANGLE, OVAL, CIRCLE, TRIANGLE and EQUILATERAL_TRIANGLE

imageView.background = BarrierTapeDrawable().apply {
  shape = Shape.EQUILATERAL_TRIANGLE
  triangleOrientation = TriangleOrientation.TOP
}

The barrier tape can be displayed as a frame. To use this mode, borderWidth must be greater than zero.

imageView.background = BarrierTapeDrawable().apply {
  borderWidth = 15
}
