我刚创建了一个用于从网站获取数据的Android应用程序.我想检查设备是否有互联网连接.如果设备具有互联网连接,请运行我的代码并获取数据并显示它,否则如果设备没有互联网,则显示无互联网连接消息.我试过这段代码来检查互联网连接.如果有互联网连接,我该如何调用代码？

我的Java代码:

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_primary);
        new FetchWebsiteData().execute();        
            }
        });

    }

    private class FetchWebsiteData extends AsyncTask<Void, Void, String[]> {
        String websiteTitle, websiteDescription,websiteDescription1,websiteDescription2,websiteDescription3,listValue,listValue1;
        ProgressDialog progress;
        private Context context;

        //check Internet connection.
        private void checkInternetConnection(){

            ConnectivityManager check = (ConnectivityManager) this.context.
                    getSystemService(Context.CONNECTIVITY_SERVICE);
            if (check != null)
            {
                NetworkInfo[] info = check.getAllNetworkInfo();
                if (info != null)
                    for (int i = 0; i <info.length; i++)
                        if (info[i].getState() == NetworkInfo.State.CONNECTED)
                        {
                            Toast.makeText(context, "Internet is connected",
                                    Toast.LENGTH_SHORT).show();

                        }

            }
            else{
                Toast.makeText(context, "not conencted …
