Question

我必须检查在甲状腺中能够或残疾的无线网络。如何做到这一点?

I have to check this one.(setting->location & security->use wireless networks) not in the(Settings -> Wireless & network settings -> wifi). I tried for second one.

在编码中,尽管我采用飞机方式,但现在显示互联网连接。因此,我必须检查电离层和安放网、安全网和无线网络。

我的法典:

 private boolean checkInternetConnection() {
        ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
        // test for connection
        if (cm.getActiveNetworkInfo() != null
                && cm.getActiveNetworkInfo().isAvailable()
                && cm.getActiveNetworkInfo().isConnected()) {
            Log.e("TAG", "Internet Connection Present");
            return true;
        } else {
            Log.e("TAG", "Internet Connection Not Present");
            return false;
        }
    }

请协助我。

Answer 1

如果你想要检查(设定和开发;地点和安放;安全及专用无线网络),那么你就必须检查这一状况。

private boolean connectionAvailable() {
    boolean connected = false;
    ConnectivityManager connectivityManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
    if (connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_MOBILE).getState() == NetworkInfo.State.CONNECTED ||
            connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI).getState() == NetworkInfo.State.CONNECTED) {
        //we are connected to a network
        connected = true;
    }
    return connected;
}

Answer 2

private boolean connectionAvailable() {
    boolean connected = false;
    ConnectivityManager connectivityManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
    if (connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_MOBILE).getState() == NetworkInfo.State.CONNECTED ||
            connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI).getState() == NetworkInfo.State.CONNECTED) {
        //we are connected to a network
        connected = true;
    }
    return connected;
}
