Guide

XML Guide:

QuatroGradeView tag:

<com.gigamole.quatrograde.QuatroGradeView/>

QuatroGradeView attributes:

The qgv_topColors and qgv_topPositions arrays should have equals size. The same for the qgv_bottomColors and qgv_bottomPositions. Basically, the color position range from 0.0 to 1.0.

The qgv_colors tag is dominant, so it will override the qgv_topColors, qgv_topPositions, qgv_bottomColors, qgv_bottomPositions attributes.

The qgv_orientation change is useful for presenting 3+ colors on the wide or tall screens(depends on the orientation).

Code Guide:

Methods to setup the QuatroGradeView: setColors, setColorsRes, setColorsInt, setGrades.

The GradeModel is the holder of the color and its position on the gradient.

To change the orientation: quatroGradeView.orientation.

Methods to animate or change the single GradeModel: getTopGrades, getBottomGrades, getGrades.

The refresh method is applying changes and redraws gradients after the manipulation over the GradeModels.
