我有简单的 Jar 项目,由 android 应用程序引用。然后,我有 Functions.java 用于我想要创建单元测试类的常用函数。
以下是 Functions.java 中的示例函数:
public static double getAltitudeBySensor(float atmosphericPressure) {
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.GINGERBREAD
&& atmosphericPressure > 0d) {
return SensorManager.getAltitude(SensorManager.PRESSURE_STANDARD_ATMOSPHERE, atmosphericPressure);
}
return 0d;
}
public static double toPixelX(double imageSize, android.location.Location upperLeft, android.location.Location lowerRight, android.location.Location target) {
double hypotenuse = upperLeft.distanceTo(target);
double bearing = upperLeft.bearingTo(target);
double currentDistanceX = Math.sin(bearing * Math.PI / OneEightyDeg) * hypotenuse;
// "percentage to mark the position"
double totalHypotenuse = upperLeft.distanceTo(lowerRight);
double totalDistanceX = totalHypotenuse * Math.sin(upperLeft.bearingTo(lowerRight) * Math.PI / OneEightyDeg);
double currentPixelX = currentDistanceX / totalDistanceX * imageSize;
return currentPixelX;
}
感谢任何有关正确方向的指导。
