参考https://stackoverflow.com/a/6922448/2771869
LocationManager locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
String provider = locationManager.getBestProvider(new Criteria(), true);
Location locations = locationManager.getLastKnownLocation(provider);

你的代码对我来说似乎很好。
将以下代码放在活动中setContentView（）的正下方。
if (android.os.Build.VERSION.SDK_INT > 9) {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}
如果在保存应用程序后出现错误，则只需将鼠标悬停在错误上并添加@SuppressLint（＆＃34; NewApi＆＃34;）（Eclipse将为您提供鼠标悬停选项）。例如，您将收到错误的单词＆＃34; build＆＃34;。如果有效，请告诉我。
