Direction-Line

Library designed to display an array of arrows that can be adjusted direction and color. Can be used for a variety of uses, directions of a particular object at different times, addition to the graph, etc.

Vertical and horizontal step line indicator.

Setup

Add it in your root build.gradle at the end of repositories:

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

Step 2. Add the dependency:

dependencies {
    implementation 'com.github.guy-4444:Direction-Line:1.01.04'
}

Usage

  • angle values - 0 -> 360

Direction-Line Examples:

360 angle colorful direction line:

final int SIZE = 30;
ArrayList<Integer> nums = new ArrayList<>();
for (int i = 0; i < SIZE; i++) {
    nums.add((int) (i*(360 / SIZE)));
}

directionLineLayout1.setStepLines(this, DirectionLineLayout.LayoutOrientation.HORIZONTAL, 2, SIZE, R.color.skv_arrow_color, 80, R.drawable.ic_arrow);
for (int i = 0; i < directionLineLayout1.getSize(); i++) {
    directionLineLayout1.setUnitDirection(i, nums.get(i));
    int color = Color.HSVToColor(255, new float[]{(float) nums.get(i), 1.0f, 1.0f});
    directionLineLayout1.setUnitColor(i, (int) color);
}

720 angle red-blue direction line:

        final int SIZE = 60;
        ArrayList<Integer> nums = new ArrayList<>();
        for (int i = 0; i < SIZE; i++) {
            nums.add((int) (i*(720.0 / SIZE)));
        }

        directionLineLayout2.setStepLines(this, DirectionLineLayout.LayoutOrientation.HORIZONTAL, 1, 60, R.color.skv_arrow_color, 40, R.drawable.ic_arrow);
        for (int i = 0; i < directionLineLayout2.getSize(); i++) {
            double yaw = nums.get(i);
            directionLineLayout2.setUnitDirection(i, (int) yaw);
            double X = Math.abs(Math.sin(yaw/360.0*Math.PI)) * 255;
            int color = Color.rgb((int) X, 0, (int) (255-X));
            directionLineLayout2.setUnitColor(i, color);
        }
