我试图改变NFC设置（开/关）编程方式在Android 2.3.3。

在手机上，在无线和网络设置， 你可以选择设置你是否要使用NFC读取和交换标签与否。

所以，我想切换在我的应用此设置。 但我似乎无法找到一个API，用于这一点。

我在找一些code，它很可能是这样的：

  WifiManager无线=（WifiManager）context.getSystemService（Context.WIFI_SERVICE）;
wifi.setWifiEnabled（开/关）;
 

解决方案

您无法将其开/关手动，但你可以发送用户的preferences如果是关闭：

 如果（！nfcForegroundUtil.getNfc（）。IsEnabled的（））
    {
        Toast.makeText（getApplicationContext（），请激活NFC和preSS返回，返回给应用程序！，Toast.LENGTH_LONG）.show（）;
        startActivity（新意图（android.provider.Settings.ACTION_WIRELESS_SETTINGS））;
    }
 

方法 getNfc（）仅返回 nfcadapter ：

NFC = NfcAdapter.getDefaultAdapter（activity.getApplicationContext（））;

I trying to change NFC settings (on/off) programmatically on Android 2.3.3.

On the phone, under the "Wireless & network settings", you can choose to set whether you want to use NFC to read and exchange tags or not.

So I would like to toggle this setting in my application. But I can't seem to find an api for this.

I'm looking for some code that would probably look like this:

WifiManager wifi = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
wifi.setWifiEnabled( on/off );

You can not turn it on/off manually but you can send the user to the preferences if it is off:

    if (!nfcForegroundUtil.getNfc().isEnabled())
    {
        Toast.makeText(getApplicationContext(), "Please activate NFC and press Back to return to the application!", Toast.LENGTH_LONG).show();
        startActivity(new Intent(android.provider.Settings.ACTION_WIRELESS_SETTINGS));
    }

Method getNfc() just returns the nfcadapter:

nfc = NfcAdapter.getDefaultAdapter(activity.getApplicationContext());
