Guide

XML Guide:

QuatroGradeView tag:

<com.gigamole.quatrograde.QuatroGradeView/>

QuatroGradeView attributes:

Attribute Description
qgv_colors The array of color values (size 4). Setup with 4 colors on each corner: top-left, top-right, bottom-left, bottom-right.
qgv_topColors The array of color values (size 2+). Provides the top gradient colors.
qgv_topPositions The string-array of float values (size 2+). Provides the top gradient colors positions.
qgv_bottomColors The array of color values (size 2+). Provides the bottom gradient colors.
qgv_bottomPositions The string-array of float values (size 2+). Provides the bottom gradient colors positions.
qgv_orientation The enum of horizontal or vertical value. Set the orientation of the top and bottom gradients. In the vertical orientation the top gradient moves to the left, and bottom moves to the right.

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.

Please, follow the Sample App to properly discover these features.
