在Criteria
类中,有两个常量ACCURACY_HIGH
和ACCURACY_FINE
,它们显然用于要求LocationManager
返回更高精度的位置更新。以下是文档对每个常量的说明:
public static final int ACCURACY_FINE (在 API 级别 1 中添加)
A constant indicating a finer location accuracy requirement Constant Value: 1 (0x00000001)
public static final int ACCURACY_HIGH (在 API 级别 9 中添加)
a constant indicating a high accuracy requirement - may be used for horizontal, altitude, speed or bearing accuracy. For horizontal and vertical position this corresponds roughly to an accuracy of less than 100 meters. Constant Value: 3 (0x00000003)
有谁知道这两个常数中的哪一个提供(即要求)最高水平的准确度?
