CustomGauge

Simple gauge view

Installation

• Add the following to your build.gradle:

repositories {
    jcenter()
}

dependencies {
    compile 'pl.pawelkleczkowski.customgauge:CustomGauge:1.0.4'
}

• Add "pl.pawelkleczkowski.customgauge.CustomGauge" view in your layout (example below)
• Find CustomGauge view in your activity and use methods "setValue()" and "getValue()" to manage view

Attributes

Available view attributes:

• startAngel (left start angel in degrees) - please be informed that gauge is drawn as an arc from startAngel (where to start) with sweepAngel (how many degrees arc is); what is more it's clockwise (right - 0, bottom - 90, left - 180, top - 270 degrees); if for example you want full circle start on 90 with 360 sweepAngel
• sweepAngel - as described above
• startValue - scale start value
• endValue - scale end value
• strokeWidth - stroke width
• strokeColor - resource color (cannot be selector)
• strokeCap - style of circle stroke (BUTT - straight, ROUND - rounded)
• pointSize - defined for pointer drawn on current value (first example) - tells how wide pointer should be; if not set pointer is drawn from start value to current value (like second example)
• pointStartColor - used for gradient pointer (second example)
• pointEndColor - used for gradient pointer (second example)
• dividerSize - size of divider related to values; if declared dividers will be drawn(!); e.g. if your start value is 50 and end value is 120 dividerSize set to 2 means that divider will have 1/35 of gauge total width - in other words it will have size of 2 points of gauge scale
• dividerStep - tells how often dividers will be drawn; it's in percentage values(!); e.g. if you want to have dividers drawn each 20% of scale just set it to 20 and you will have 6 dividers drawn (with first and last)
• dividerColor - color of divider
• dividerDrawFirst - whether to draw first divider or no
• dividerDrawLast - whether to draw last divider or no
