本文介绍了Android的 - 如何每次获取用户当前位置基于SIM卡的网络的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想获得用户的当前位置（经度和纬度）移动）。不一定确切位置，但即使大致位置。是否有可能得到它。如果有任何可以解释的，包括code;我在谷歌搜索，但没有得到正确的答案相关...
I want to get the user's current location (latitude and longitude) always using Sim-based network only, not by using any other networks (like WiFi, Mobile Data, GPS and other Network and even all these are in Disabled mode in mobile). Not necessarily exact location but even approximate location. Is there any possibility to get it. If any of you can explain and include code; I searched in Google but did not get the correct related answer...
由于提前
推荐答案
下面把我的code得到经度和纬度。它是整个项目。看一看。它完美的罚款。然而，你必须开启GPS和WIFI自己，因为在4.0以上版本中，你不能开启GPS编程
Here take my code to get longitude and latitude. It is the whole project. Have a look. It works perfectly fine. However you have to turn on GPS and WIFI yourself because above version 4.0 you cant turn on gps programmatically
使用我的code得到的位置。打开您的GPS和WiFi之前： -
Use my code to get the location. Turn your gps and wifi on before :-
使用我的code。我已经成功地找到使用坐标我目前的地址，但对于您必须启用WIFI和GPS。
首先添加所有这些权限在你的Android清单文件
Use my Code. I have successfully found my current address using coordinates but for that you have to enable wifi and gps. first add all these permissions in your android manifest file
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
