android - 如何检查 WiFi 或数据连接是否已打开但是否可以访问互联网

Question

我想检查 WiFi 或移动数据连接是否(能够检查)但是否能够访问互联网

   public static boolean isNetworkAvailable(Context context) {
            ConnectivityManager connectivityManager
                    = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
            NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
            return activeNetworkInfo != null && activeNetworkInfo.isConnected();
        }



  public static boolean isInternetAccessible(Context context) {
        if (isNetworkAvailable(context)) {
            try {
                HttpURLConnection urlc = (HttpURLConnection) (new URL("http://aapapps.com").openConnection());
                urlc.setRequestProperty("User-Agent", "Test");
                urlc.setRequestProperty("Connection", "close");
                urlc.setConnectTimeout(1500);
                urlc.connect();
                return (urlc.getResponseCode() == 200);
            } catch (IOException e) {
                Log.e("LOG_TAG", "Couldn't check internet connection", e);
            }
        } else {
            Log.d("LOG_TAG", "Internet not available!");
        }
        return false;
    }

尝试它的工作代码

public boolean isConnectingToInternet(){
ConnectivityManager connectivity = (ConnectivityManager) _context.getSystemService(Context.CONNECTIVITY_SERVICE);
  if (connectivity != null) 
  {
      NetworkInfo[] info = connectivity.getAllNetworkInfo();
      if (info != null) 
          for (int i = 0; i < info.length; i++) 
              if (info[i].getState() == NetworkInfo.State.CONNECTED)
              {
                  return true;
              }

  }
  return false;
}
