1
00:00:00,230 --> 00:00:01,370
解决方案是这样

2
00:00:01,370 --> 00:00:04,282
创建 mLocationRequest 只需调用 LocationRequest.create

3
00:00:04,282 --> 00:00:08,660
然后设置较高的精度优先级

4
00:00:08,660 --> 00:00:12,195
调用 LocationRequest.setPriority 并向其传递一个常量

5
00:00:12,195 --> 00:00:16,690
PRIORITY_HIGH_ACCURACY 你可以在定位请求类找到此常量

6
00:00:16,690 --> 00:00:20,950
我们已将间隔设为 1000 毫秒 最后

7
00:00:20,950 --> 00:00:25,600
在 FusedLocationApi 上需要做的就是 requestLocationUpdates

8
00:00:25,600 --> 00:00:30,350
并将其传递到 GoogleApiClient、LocationRequest 和 this

9
00:00:30,350 --> 00:00:34,908
引用到本 activity 这样回调将到达此 activity

10
00:00:34,908 --> 00:00:36,850
所有这些代码应在一行上

11
00:00:36,850 --> 00:00:40,080
我刚将该行分为几个单独的行 以便于读取

12
00:00:40,080 --> 00:00:42,900
现在 因为你请求进行位置更新

13
00:00:42,900 --> 00:00:47,470
所以需要实施一个称为 on location changed 的回调

14
00:00:47,470 --> 00:00:51,600
该回调正如其名称所示 每当位置即使改变一点点时将被调用

15
00:00:51,600 --> 00:00:55,470
此间隔和此高精度可确定此改变
