推荐答案

有没有做到这一点的具体途径。我通常遵循一个超时的方式在这里你可以等待约30-45秒得到修复，如果你没有得到该时间内修复，你可以推断出GPS定位不能的当前位置获得用户。

There is no specific way to do that. I usually follow a time-out approach where you can wait for about 30-45 seconds to get a fix and if you do not get a fix within that time, you can infer that the GPS fix cannot be obtained at the current location of the user.

在情况下，解决方法是可用的和你onLocationChanged（）方法获取调用，你应该使用getAccuracy（）和的getTime（）的组合来接受修复和推断的信号强度。

In case the fix is available and your onLocationChanged() method is getting called, you should use the combination of getAccuracy() and getTime() to accept the fix and infer about the strength of the signal.
