This should be a multiple of majorNickInterval. 29 | #### valuePerNick 30 | Float value (interval) per nick. 31 | #### majorNickInterval 32 | Integer interval (number of nicks) between enlarged nicks. 33 | 34 | *Note that there is always a major nick on top, that is at 0 degrees, so 35 | it is advisable that the sum of the min and max value be divisible by 2.* 36 | 37 | #### minValue 38 | Float minimum value. 39 | #### maxValue 40 | Float maximum value. 41 | #### intScale 42 | Boolean for an integer scale (defaults to true). 43 | #### initialValue 44 | Float initial value. 45 | #### labelTextSize 46 | Float text size for the number labels (defaults to a calculated value). 47 | #### faceColor 48 | Integer face color. 49 | #### scaleColor 50 | Integer scale color. 51 | #### needleColor 52 | Integer needle color. 53 | #### needleShadow 54 | Boolean to apply a shadow effect to the needle (defaults to true). 55 | #### upperText 56 | String to display on upper gauge face (e.g. a quantity). 57 | #### lowerText 58 | String to display on lower gauge face (e.g. a unit). 59 | #### textSize 60 | Float text size for upper and lower text. 61 | #### upperTextSize 62 | Float text size for upper text. 63 | #### lowerTextSize 64 | Float text size for lower text. 65 | 66 | *Text size is in pixels at a screen width (max. canvas width/height) of 1080 and is scaled 67 | accordingly at different resolutions. E.g. a value of 48 is unchanged at 1080 x 1920 68 | and scaled down to 27 at 600 x 1024.* 69 | 70 | ### Public methods 71 | #### void setValue(float value) 72 | Set gauge to value. 73 | #### void moveToValue(float value) 74 | Animate gauge to value. 75 | #### void setUpperText(String text) 76 | Set string to display on upper gauge face. 77 | #### void setLowerText(String text) 78 | Set string to display on lower gauge face. 79 | #### void setTextSize(float relative pixels) 80 | Set a text size for the upper and lower text. 81 | #### void setUpperTextSize(float relative pixels) 82 | Set or override the text size for the upper text. 83 | #### void setLowerTextSize(float relative pixels) 84 | Set or override the text size for the lower text. 85 | #### void setDeltaTimeInterval(int value) 86 | Set the delta time between movement steps during needle animation (default: 5 ms). 87 | #### void setNeedleStepFactor(float value) 88 | Set the factor that determines the step size during needle animation (default: 3f). 89 | The actual step size is calulated as follows: step_size = step_factor * scale_value_per_degree. 90 | #### void setMinValue(float value) 91 | Set the minimum scale value. 92 | #### void setMaxValue(float value) 93 | Set the maximum scale value. 94 | #### void setTotalNicks(int nicks) 95 | Set the total amount of nicks on a full 360 degree scale. Should be a multiple of majorNickInterval. 96 | #### void setValuePerNick(float value) 97 | Set the value (interval) per nick. 98 | #### void setMajorNickInterval(int interval) 99 | Set the interval (number of nicks) between enlarged nicks. 100 | 101 | *Text size is in pixels at a screen width (max. canvas width/height) of 1080 and is scaled 102 | accordingly at different resolutions. E.g. a value of 48 is unchanged at 1080 x 1920 103 | and scaled down to 27 at 600 x 1024.* 104 | 105 | ### Javadoc 106 | [http://pygmalion.nitri.org/javadoc/gauge/](http://pygmalion.nitri.org/javadoc/gauge/) 107 | 108 | 109 | ### Gradle 110 | 111 | Add the JitPack repository in your root build.gradle at the end of repositories: 112 | 113 | ``` 114 | repositories { 115 | maven { 116 | url 'https://www.jitpack.io' 117 | } 118 | } 119 | ``` 120 | 121 | Add the dependency: 122 | 123 | ``` 124 | dependencies { 125 | implementation 'com.github.Pygmalion69:Gauge:1.5.2' 126 | } 127 | ``` 128 | 129 | ### App implementing this view 130 | 131 | [ErsaAndroid](https://github.com/Pygmalion69/ErsaAndroid) 132 | -------------------------------------------------------------------------------- /gradlew: -------------------------------------------------------------------------------- 1 | #!/usr/bin/env bash 2 | 3 | ############################################################################## 4 | ## 5 | ## Gradle start up script for UN*X 6 | ## 7 | ############################################################################## 8 | 9 | # Add default JVM options here.
