67 | you need your users help to calibration RulerView for there devices, that's why you should use `RulerCalibrationView` to do that. 68 | 69 | 70 | 71 | the user can easily slide to match real measurements. 72 | 73 | to use that, add `RulerCalibrationView` to your `layout.xml` 74 | ```xml 75 | 79 | ``` 80 | 81 | then you can get the **coefficient** and save it, then pass it to RulerView 82 | ```kotlin 83 | // coefficient is a float number 84 | val myCoefficient = rulerCalibrationView.coefficient 85 | // save it somewhere (SharedPreferences maybe) 86 | saveNumber(myCoefficient) 87 | 88 | ... 89 | 90 | // pass it to your ruler 91 | rulerView.coefficient = myCoefficient 92 | ``` 93 | 94 | ### OneDimensionRulerView 95 | 96 | to measure distance between two lines 97 | 98 | 99 | 100 |
