推荐答案

Android已经获得用户的当前位置的三种方式。

Android has three ways of getting the current location of the user.


  1. 通过Wi-Fi

  2. 通过你的networkprovider。

  3. 通过对Android设备的GPS芯片。

在对这些最准确的方法是从全球定位系统获得的坐标。这将让你的准确位置在北纬多头,但它也将最常使用的电池。这通常是在导航地图注重精度的使用。

Out of these the most accurate method is to get the co-ordinates from GPS. This will get your accurate location in lat longs but it will also use most of the battery. This is generally used in navigation maps where accuracy is Important.

,两种方法的其余部分是不太准确的,但也可以使用更少的电池。如果当前位置的准确性并不重要,您可以使用这些方法的后two.All都可以通过的LocationManager的android

the rest of the two methods are less accurate but also use less battery. If the accuracy of current location is not that important you can use the later two.All of these methods are available through LocationManager of android.

编辑:

        // To get Updates From GPS Use
    mlocManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0,
            currentlocation);

       //To get Updates From network Use
    mlocManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0,
            currentlocation);
