Ich habe erfolgreich die wifi direkte Beispieldemo implementiert und die Zwei-Wege-Bildfreigabe funktioniert ordnungsgemäß, aber mein Problem ist, wenn ein Gerät A sendet eine Einladung zum Verbinden mit Gerät B und Gerät B abbrechen Ich kann diesen Callback für dieses Ereignis nicht verarbeiten, da es von Android generiert wird.WiFi Direct Image Sharing auf Peer-Gerät in Android
Jeder, der mir bei der Lösung meines Problems helfen kann.
Folgende ist meine Sendung Empfänger Code und schließen Code:
/**
* A BroadcastReceiver that notifies of important wifi p2p events.
*/
public class WiFiDirectBroadcastReceiver extends BroadcastReceiver {
private WifiP2pManager manager;
private Channel channel;
private WiFiDirectActivity activity;
/**
* @param manager WifiP2pManager system service
* @param channel Wifi p2p channel
* @param activity activity associated with the receiver
*/
public WiFiDirectBroadcastReceiver(WifiP2pManager manager, Channel channel,
WiFiDirectActivity activity) {
super();
this.manager = manager;
this.channel = channel;
this.activity = activity;
}
/*
* (non-Javadoc)
* @see android.content.BroadcastReceiver#onReceive(android.content.Context,
* android.content.Intent)
*/
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (WifiP2pManager.WIFI_P2P_STATE_CHANGED_ACTION.equals(action)) {
// UI update to indicate wifi p2p status.
int state = intent.getIntExtra(WifiP2pManager.EXTRA_WIFI_STATE, -1);
if (state == WifiP2pManager.WIFI_P2P_STATE_ENABLED) {
// Wifi Direct mode is enabled
activity.setIsWifiP2pEnabled(true);
} else {
activity.setIsWifiP2pEnabled(false);
activity.resetData();
}
Log.d(WiFiDirectActivity.TAG, "P2P state changed - " + state);
} else if (WifiP2pManager.WIFI_P2P_PEERS_CHANGED_ACTION.equals(action)) {
// request available peers from the wifi p2p manager. This is an
// asynchronous call and the calling activity is notified with a
// callback on PeerListListener.onPeersAvailable()
if (manager != null) {
manager.requestPeers(channel, (PeerListListener) activity.getFragmentManager()
.findFragmentById(R.id.frag_list));
}
Log.d(WiFiDirectActivity.TAG, "P2P peers changed");
} else if (WifiP2pManager.WIFI_P2P_CONNECTION_CHANGED_ACTION.equals(action)) {
if (manager == null) {
return;
}
NetworkInfo networkInfo = (NetworkInfo) intent
.getParcelableExtra(WifiP2pManager.EXTRA_NETWORK_INFO);
if (networkInfo.isConnected()) {
// we are connected with the other device, request connection
// info to find group owner IP
DeviceDetailFragment fragment = (DeviceDetailFragment) activity
.getFragmentManager().findFragmentById(R.id.frag_detail);
manager.requestConnectionInfo(channel, fragment);
} else {
// It's a disconnect
activity.resetData();
}
} else if (WifiP2pManager.WIFI_P2P_THIS_DEVICE_CHANGED_ACTION.equals(action)) {
DeviceListFragment fragment = (DeviceListFragment) activity.getFragmentManager()
.findFragmentById(R.id.frag_list);
fragment.updateThisDevice((WifiP2pDevice) intent.getParcelableExtra(
WifiP2pManager.EXTRA_WIFI_P2P_DEVICE));
}
}
}
Für den Anschluss i den folgenden Code verwendet:
WifiP2pConfig config = new WifiP2pConfig();
config.deviceAddress = device.deviceAddress;
config.wps.setup = WpsInfo.PBC;
if (progressDialog != null && progressDialog.isShowing()) {
progressDialog.dismiss();
}
device.wps.setup = WpsInfo.PBC;
device.groupOwnerIntent = 0; // I want this device to become the owner
manager.connect(channel, device, new ActionListener() {
@Override
public void onSuccess() {
// WiFiDirectBroadcastReceiver will notify us. Ignore for now.
}
@Override
public void onFailure(int reason) {
Toast.makeText(WiFiDirectActivity.this, "Connect failed. Retry.",
Toast.LENGTH_SHORT).show();
}
});
