A few relatively simple looking and somewhat customizable Android user controls.

Just to show their functionality, all controls have been included in the "Gauge" screen of the PhoneTest project. The project itself is set with minimum requirement of Android 4.1 (API level 16) while targeting Android 11 (API level 30).

• AngleIndicator
  • a control to indicate rotational position/angle, measured counterclockwise from the zero/home position.
  • zero/home position could be selected as either of East (0), North (90), West (180) or South (270).
  • designed to show -360 to 360 values and will reduce all other values to this range (use the getCurrentValue() method to get the actual value).
  • could potentially be used as a weather vane since it can show the Direction suffix.
  • possibly use either Arc or Pie to sweep the angle for better visual appearance, see the screenshot.
  • it has publicly accessible methods: getCurrentValue() for reading and setCurrentValue(newFloatValue) for writing.
  • all custom properties start with "ai".
• RoundGauge
  • a gauge control that could be used for miscelaneous measurements.
  • min/max values can be set individually.
  • it has publicly accessible methods: getGaugeCurrentValue() for reading and setGaugeCurrentValue(newFloatValue) for writing.
  • all custom properties start with "gauge".
• LEDLight
  • a control that can be turned ON/OFF and Blink (which is of a higher order but will restore the last ON/OFF state once the blinking stops).
  • it has publicly accessible methods: isLED_ON() and isLED_Blink() for reading and setLED_ON(newBooleanValue) and setLED_Blink(newBooleanValue) for writing.
  • all custom properties start with "led".

Screenshot is included in each control's folder.

All it should take is to:

• Add the control's java file to your app's src/main/java/com.e.whatever folder (copy-paste).
• Add the control's xml file to your app's src/main/res/values folder (copy-paste).
• Save it all, Sync with Gradle, Build/Rebuild Project, open one of your activity layout files and look for the new control under "Project".
