我想下面的code，以检查是否我的手机连接到无线网络，它工作得很好，当我想知道我的手机连接到网络，但它未能提供有关上网信息...类似ping命令任何网站。 其实我跟很多的联系，但始终无人接听，所以我会很感激，如果有人可以提供帮助。

I tried the below code to check whether my mobile is connected to a wireless network and it works well when I want to know if my mobile is connected to the network, but it fails to give information about the internet access ... something like "Pinging" any website. Actually I followed many links but still no answer, so I'll be so thankful if anybody can help.

在此先感谢。

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    Toast t = new Toast(getApplicationContext());

    if (isInternetOn()) {
         // INTERNET IS AVAILABLE, DO STUFF..
         Toast.makeText(ConnectivityTestActivity.this,"Network is Available", Toast.LENGTH_LONG).show();

         }
    else {
         // NO INTERNET AVAILABLE, DO STUFF..
        Toast.makeText(ConnectivityTestActivity.this,"No Network Available", Toast.LENGTH_LONG).show();

        }
}

public final boolean isInternetOn() {


    ConnectivityManager connec =  (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
    // ARE WE CONNECTED TO THE NET
    if ( connec.getNetworkInfo(0).getState() == NetworkInfo.State.CONNECTED ||
    connec.getNetworkInfo(0).getState() == NetworkInfo.State.CONNECTING ||
    connec.getNetworkInfo(1).getState() == NetworkInfo.State.CONNECTING ||
    connec.getNetworkInfo(1).getState() == NetworkInfo.State.CONNECTED ) {
    // MESSAGE TO SCREEN FOR TESTING (IF REQ)
    //Toast.makeText(this, connectionType + " connected", Toast.LENGTH_SHORT).show();
    return true;
    } else if ( connec.getNetworkInfo(0).getState() == NetworkInfo.State.DISCONNECTED ||  connec.getNetworkInfo(1).getState() == NetworkInfo.State.DISCONNECTED  ) {

    return false;
    }
    return false;
    }}

推荐答案

其实我用同样的函数 isInternetOn（），但我删除的连接状态。 它有如果连接或不连接并且如果尝试连接到检查连接的状态。这并没有为我工作，所以我删除连接状态检查，然后它的工作。

Actually I used the same function isInternetOn() but I removed the connecting condition. It had to check the status of connection if connected or not and if it is trying to connect. This didn't work for me, so I removed connecting status checking and then it worked.

感谢所有的答复。

public final boolean isInternetOn()
{
  ConnectivityManager connec = (ConnectivityManager)
    getSystemService(Context.CONNECTIVITY_SERVICE);

  // ARE WE CONNECTED TO THE NET
  if ( connec.getNetworkInfo(0).getState() == NetworkInfo.State.CONNECTED ||
       connec.getNetworkInfo(1).getState() == NetworkInfo.State.CONNECTED )
  {
    // MESSAGE TO SCREEN FOR TESTING (IF REQ)
    //Toast.makeText(this, connectionType + " connected", Toast.LENGTH_SHORT).show();
    return true;
  }
  else if ( connec.getNetworkInfo(0).getState() == NetworkInfo.State.DISCONNECTED
    ||  connec.getNetworkInfo(1).getState() == NetworkInfo.State.DISCONNECTED  )
  {
    return false;
  }

  return false;
}
