【问题描述】：

我发现了对等点，但我无法连接到其中之一。我觉得我的 BroadcastReceiver 没有得到 WIFI_P2P_CONNECTION_CHANGED_ACTION 因为它不执行里面的内容。

连接（）：

    public void connect(View v) 
    // Picking the first device found on the network.
    WifiP2pDevice device = (WifiP2pDevice) peers.get(0);

    WifiP2pConfig config = new WifiP2pConfig();
    config.deviceAddress = device.deviceAddress;
    config.wps.setup = WpsInfo.PBC;
    config.groupOwnerIntent = 0;


    mManager.connect(mChannel, config, new WifiP2pManager.ActionListener() 
        @Override
        public void onSuccess() 
            // WiFiDirectBroadcastReceiver will notify us. Ignore for now.
            Toast.makeText(MultiActivity.this, "Connect initiated" ,
                    Toast.LENGTH_SHORT).show();

        

        @Override
        public void onFailure(int reason) 
            Toast.makeText(MultiActivity.this, "Connect failed. Retry.",
                    Toast.LENGTH_SHORT).show();
        
    );

onReceive()：

else if (WifiP2pManager.WIFI_P2P_CONNECTION_CHANGED_ACTION.equals(action)) 
        // Connection state changed!  We should probably do something about
        // that.
        Toast.makeText(activity, "ca marche",
                Toast.LENGTH_SHORT).show();

        if (mManager == 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
            mManager.requestConnectionInfo(mChannel, connectionListener);
        

    

Toast "ca marche" 永远不会出现在屏幕上。 请帮帮我，谢谢。

【参考方案1】：

确保使用正确的 IntentFilter 注册您的广播接收器。

例如：

创建新的意图过滤器：IntentFilter tmpFilter = new IntentFilter(); 添加您感兴趣的操作：tmpFilter.addAction(WifiP2pManager.WIFI_P2P_CONNECTION_CHANGED_ACTION); 向广播接收器注册（最好使用 onResume()）：registerReceiver(p2PBroadcastReceiver, tmpFilter)

祝你好运。

【讨论】：

我们可以在清单中静态注册的接收器上使用 wifi p2p 事件吗？我已在清单中注册，但没有任何内容被识别。

【参考方案2】：

public void connect(WifiP2pConfig config) 
    manager.connect(channel, config, new WifiP2pManager.ActionListener() 

        @Override
        public void onSuccess() 
            // WiFiDirectBroadcastReceiver will notify us. Ignore for now.
            peerListener.connectionSuccess();
        

        @Override
        public void onFailure(int reason) 
            peerListener.connectionFailure();
            Toast.makeText(activity, "Connect failed. Retry.", Toast.LENGTH_SHORT).show();
        
    );
