Gps状态的判断和开启关闭

//判断GPS的状态

public String checkGPSStatus() {
  String result = "";
  LocationManager lManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
  if (!lManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
   result = "未开启";
  } else {
   result = "开启";
  }
  return result;
 }

 // GPS自动开启和关闭的操作,如果开启了，调用此时就关闭，如果是关闭状态，调用此时为开启
 public static void GPSoper(Context v) {
  gpsIntent = new Intent();
  gpsIntent.setClassName("com.android.settings",
    "com.android.settings.widget.SettingsAppWidgetProvider");
  gpsIntent.addCategory("android.intent.category.ALTERNATIVE");
  gpsIntent.setData(Uri.parse("custom:3"));
  try {
   PendingIntent.getBroadcast(v, 0, gpsIntent, 0).send();
  } catch (CanceledException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
 }
