Google地图上的蓝色闪光灯(Arc) [英] Blue flash light (Arc) on Google Maps

问题描述

有什么办法可以访问Google地图上出现的蓝色闪光灯?我在不同的论坛上都读到过，这个蓝色弧线代表了磁传感器的可靠性，在Android中有什么方法可以使用它吗?

Is there any way to have access to the blue flash light appears on google map? I have read in different forums that this blue arc is representative of the reliability of the magnet sensor, is there any way to have access to it in android?

推荐答案

我通过了用于磁铁输出的Android SDK.我发现了一种测量基于磁体运动方向的精度的方法.您看到以下方法了吗?

I went through Android SDK for magnet outputs. I have found one method that measure the accuracy of magnet based direction of movement. Have you seen following method?

@Override
public void onAccuracyChanged(Sensor sensor, int i) {
    if(sensor.getType() == Sensor.TYPE_MAGNETIC_FIELD){

    }
}

这将基于磁体的航向估计输出4级精度.

This outputs the accuracy in 4 levels for magnet based heading estimation.
