有人可以帮我解决这个问题吗？

这是我的代码,并且mWifi.enableNetwork(netID, true)它无法启用网络,无法自动连接到指定的网络.所以我想知道我犯了什么错误？

    public class WifiConnActivity extends Activity {
    /** Called when the activity is first created. */
    final String tag = "WifiConn:...";
    EditText txt;
    WifiManager mWifi;

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

        mWifi = (WifiManager)getSystemService(Context.WIFI_SERVICE);

                    Log.d(tag, "startScan()");

                    List<ScanResult> sRet = mWifi.getScanResults();  //scan results.

                    for (int i=0; i<sRet.size(); i++)
                    {
                        ScanResult retS = sRet.get(i); 
                        txt.append("resT: " …
