本文介绍了一种在Android环境中检查网络连接状态、WiFi状态、位置服务状态的方法，并提供了实现这些功能的Java代码示例。文章详细展示了如何使用系统服务如ConnectivityManager和LocationManager来判断设备是否连接到网络、是否连接到WiFi以及位置服务是否开启。

public class NetUtils {

    public static boolean isConnected() {
        ConnectivityManager connectivity = (ConnectivityManager) MyApplication.sContext.getSystemService(Context.CONNECTIVITY_SERVICE);
        if (connectivity != null) {
            NetworkInfo info = connectivity.getActiveNetworkInfo();
            return info != null && info.isConnected();
        }
        return false;
    }

    public static boolean isWifiConnected() {
        ConnectivityManager connectivity = (ConnectivityManager) MyApplication.sContext.getSystemService(Context.CONNECTIVITY_SERVICE);
        if (connectivity != null) {
            NetworkInfo info = connectivity.getActiveNetworkInfo();
            return info != null && info.getType() == ConnectivityManager.TYPE_WIFI;
        }
        return false;
    }

    public static boolean isWifiOpen() {
        WifiManager wifiManager = (WifiManager) MyApplication.sContext.getSystemService(Context.WIFI_SERVICE);
        return wifiManager != null && wifiManager.isWifiEnabled();
    }

    public static boolean isLocationOpen() {
        LocationManager locationManager = (LocationManager) MyApplication.sContext.getSystemService(Context.LOCATION_SERVICE);
        return locationManager != null && (locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER) || locationManager
                .isProviderEnabled(LocationManager.GPS_PROVIDER));
    }

//需要实现 PermissionManager.OnRequestPermissionsListener   接口监听权限获取状态  
     (重写onPermissionGranted()  onPermissionDenied()两个函数)
    public void getPermission() {
        mPermissionManager = PermissionManager.Factory.get(this, this);
        mPermissionManager
            .checkPermission(PermissionManager.Permission.WIFI_PERMISSION, REQUEST_PERMISSION, 0, R.string
                    .permission_hint_wifi_history);
     }
    private checkPermission() {
        if (ContextCompat.checkSelfPermission(mContext, PermissionManager.Permission.WIFI_PERMISSION[0]) 
               !=  PackageManager.PERMISSION_GRANTED) {
                getPermission()
         }
     }
