Android library for using gradient views with non-standard animation

Min. SDK: 19 Kotlin

Full example you can see in sample app. You can download an APK of the sample app

What's done

1. GradientView component
2. GradientTextView component
3. Gradient vertical/horizontal orientation
4. Animation support for GradientView
5. Animation support for GradientTextView
6. Optional animation loop
7. Optional animation start after component creation
8. Animation attributes
9. Round corners support and attributes for GradientView

TODO

1. Angle cupport for gradient orientation
2. Gradient orientation angle animation
3. Gradient overlay for all type of views
4. Optimization for animation of GradientTextView
5. Improve animation loop realization

GradientView, GradientTextView attributes

• gradientOrientation
• baseColors
• startColorsPositions
• endColorsPositions
• animationOnStart
• animationStepDuration
• animationLoop
• topLeftCorner (only for GradientView)
• topRightCorner (only for GradientView)
• bottomLeftCorner (only for GradientView)
• bottomRightCorner (only for GradientView)

How to add library to your project

1. Add the JitPack repository to your build file

allprojects {
	repositories {
		...
		maven { url 'https://jitpack.io' }
	}
}

2. Add the dependency

dependencies {
	implementation 'com.github.GreyLabsDev:GradientComponents:0.5.0'
}

How to use components in .xml layout

GradientView

<com.greylabs.gradientcomponents.component.GradientView
                android:layout_width="match_parent"
                android:layout_height="240dp"
                app:gradientOrientation="horizontal"
                app:baseColors="#91276C, #0F3368"
                app:startColorsPositions="0, 0.66"
                app:endColorsPositions="0.5, 0.99"
                app:animationStepDuration="2000"
                app:animationLoop="true"
                app:animationOnStart="true"
                app:topLeftCorner="32dp"
                app:bottomRightCorner="32dp"
        />

How to use components in code

GradientTextView

       val gradientText = GradientTextView(requireContext())
       gradientText.apply {
           setOrientation(gradientOrientation)
           addGradientColor("#FFFFFF")
           addGradientColor("#91276C")
           addGradientPosition(firstColorPos, secondColorPos)
           addGradientPosition(0.9f, 1f)
           setAnimationOnStart(isAnimationEnabled)
           setLoopAnimation(isAnimationLoop)
           setAnimationStepDuration(900L)
           text = "Some text"
           initView()
      }
