可以帮助我解决这个问题吗?
这是我的代码,在mWifi.enableNetwork(netID, true)
上,它无法启用网络,也无法自动连接到指定的网络。所以我想知道我在哪里犯了错误?
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);
txt = (EditText)findViewById(R.id.editText1);
Button b1 = (Button)findViewById(R.id.B1);
b1.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v)
{
if (mWifi.startScan()) //scan now
{
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: " + retS.SSID +" " + retS.BSSID + "\n");
Log.d(tag, "resT: " + retS.SSID +" " + retS.BSSID);
if (retS.SSID.equalsIgnoreCase("TEST"))
{
txt.append("Found: " + retS.SSID +" " + retS.BSSID + "\n");
WifiConfiguration wc = new WifiConfiguration();
wc.SSID = "\""+retS.SSID+"\"";
wc.BSSID = retS.BSSID;
wc.status = WifiConfiguration.Status.ENABLED;
wc.hiddenSSID = true;
int netID = mWifi.addNetwork(wc); // add network
txt.append("addNetwork: "+ Integer.toString(netID) +"\n");
if(mWifi.enableNetwork(netID, true)) // enable network, but cannot work???????????
{
txt.append("enableNetwork: true\n");
}
}
}
}
}
});
}
}
最佳答案
我认为您需要在WifiConfiguration对象中添加WifiConfiguration.KeyMgmt
。假设它是一个开放的网络:
wc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
另外,请谨慎地假设退出对
startScan()
的调用后即可立即获得扫描结果。在这种情况下,最好的选择是在 WifiManager.SCAN_RESULTS_AVAILABLE_ACTION
上添加一个BroadcastReceiver,并从mWifi.getScanResults()
向前添加所有代码。获得mWifi.reconnect()
成功后,您将需要添加对enableNetwork()
的调用。至于初始化
WifiConfiguration wc
,如果您考虑我的here,我会很喜欢。最后,另一个好的答案是here。
