我使用下面的代碼在android手機上創(chuàng)建一個無線模式。出于某種原因它每次都會創(chuàng)建一個新模式，因此對于相同的無線網(wǎng)絡(luò)手機將會有多個模式。是否有辦法能實現(xiàn)當一個模式已經(jīng)存在時，就不要再創(chuàng)建一個新的模式?public class IVMOBILEActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView tv = new TextView(this);
TextView status = new TextView(this);
WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
WifiConfiguration wc = new WifiConfiguration();
wc.SSID = "\"MyNetwork\""; //IMP! This should be in Quotes!!
wc.hiddenSSID = true;
wc.status = WifiConfiguration.Status.ENABLED;
wc.priority = 10;
wc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
wc.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
wc.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
wc.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);

wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);

wc.preSharedKey = "\"Password\"";
WifiManager wifiManag = (WifiManager) this.getSystemService(WIFI_SERVICE);
boolean res1 = wifiManag.setWifiEnabled(true);
int res = wifi.addNetwork(wc);
Log.d("WifiPreference", "add Network returned " + res );
boolean es = wifi.saveConfiguration();
Log.d("WifiPreference", "saveConfiguration returned " + es );
boolean b = wifi.enableNetwork(res, true);
Log.d("WifiPreference", "enableNetwork returned " + b );
tv.setText("You are now connected! " +
"Version 1.0");
status.setText("The was an error connecting, please try again.");

Thread.sleep(5000);

public WifiConfiguration checkPreviousConfiguration(WifiConfiguration wc) {
List<WifiConfiguration configs = wifi.getConfigurations();
for(WifiConfiguration config : configs) {
if(config.SSID.equals(wc.SSID)) return config;
}
return wc;
}
//......
int res = wifi.addNetwork(checkPreviousConfiguration(wc));
