如何将文件传输到wifi热点主机设备？

Question

我正在尝试从另一个Android设备将文件传输到wifi热点主机Android设备，就像SHAREIT一样。 我对此没有任何线索。虽然我试过通过wifi对等（P2P）方法

http://developer.android.com/guide/topics/connectivity/wifip2p.html

我还尝试了android SDK附带的p2p文件传输示例代码。

但主要问题是，p2p必须要有一个wifi接入点。所以我用另一个Android设备创建了一个wifi热点。我已将测试设备连接到该热点网络。但是测试设备找不到热点主机设备。因此我无法传输文件。如果我将另一个设备添加到该网络，那么测试设备可以找到新连接的设备，但不能找到主机设备，但我需要将文件传输到主机设备。

修改

我试过这段代码

    final TextView deviceListText = (TextView) findViewById(R.id.list);

    final WifiP2pManager wifiP2pManager = (WifiP2pManager) getSystemService(Context.WIFI_P2P_SERVICE);

    channel = wifiP2pManager.initialize(this, getMainLooper(), channelListener);

    // wifiP2pManager.discoverPeers(channel, newActionListener);
    // wifiP2pManager.createGroup(channel, newActionListener);


    final WiFiDirectBroadcastReceiver wiFiDirectBroadcastReceiver = new WiFiDirectBroadcastReceiver(wifiP2pManager, channel, this);


    mIntentFilter = new IntentFilter();
    mIntentFilter.addAction(WifiP2pManager.WIFI_P2P_STATE_CHANGED_ACTION);
    mIntentFilter.addAction(WifiP2pManager.WIFI_P2P_PEERS_CHANGED_ACTION);
    mIntentFilter.addAction(WifiP2pManager.WIFI_P2P_CONNECTION_CHANGED_ACTION);
    mIntentFilter.addAction(WifiP2pManager.WIFI_P2P_THIS_DEVICE_CHANGED_ACTION);

    final Button stop = (Button) findViewById(R.id.button);
    final Button start = (Button) findViewById(R.id.button2);



    start.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            wifiP2pManager.discoverPeers(channel, new WifiP2pManager.ActionListener() {
                @Override
                public void onSuccess() {
                    deviceListText.setText(" discovering peers ");
                }

                @Override
                public void onFailure(int reason) {
                    deviceListText.setText("error discovering peers "+String.valueOf(reason));

                }
            });

        }
    });



    myPeerListListener = new WifiP2pManager.PeerListListener()

    {
        @Override
        public void onPeersAvailable(final WifiP2pDeviceList peers) {


            Collection<WifiP2pDevice> devicesAddressObj = peers.getDeviceList();

            for (final WifiP2pDevice newDevice : devicesAddressObj) {


                //  deviceListText.setText(newDevice.deviceName);
                config.deviceAddress = newDevice.deviceAddress;


                wifiP2pManager.connect(channel, config, new WifiP2pManager.ActionListener() {
                    @Override
                    public void onSuccess() {
                        deviceListText.setText(" connected ");
                    }

                    @Override
                    public void onFailure(int reason) {
                        deviceListText.setText(" not connect , reason: " + String.valueOf(reason));

                    }
                });
            }

        }

    };

*这是我的广播接收器*

public class WiFiDirectBroadcastReceiver extends BroadcastReceiver {

    private WifiP2pManager mManager;
    private WifiManager wifiManager2;
    private WifiP2pManager.Channel mChannel;
    private Activity mActivity;
    final TextView deviceListText = (TextView) findViewById(R.id.list);


    public WiFiDirectBroadcastReceiver(WifiP2pManager manager, WifiP2pManager.Channel channel,
                                       Activity activity) {
        super();
        this.mManager = manager;
        this.mChannel = channel;
        this.mActivity = activity;
    }



    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        StringBuilder stringBuilder = new StringBuilder();




        if (WifiP2pManager.WIFI_P2P_STATE_CHANGED_ACTION.equals(action)) {
            // Check to see if Wi-Fi is enabled and notify appropriate activity



        } else if (WifiP2pManager.WIFI_P2P_PEERS_CHANGED_ACTION.equals(action)) {
            // Call WifiP2pManager.requestPeers() to get a list of current peers

            if (mManager != null) {
                mManager.requestPeers(mChannel, myPeerListListener);
            }


        } else if (WifiP2pManager.WIFI_P2P_CONNECTION_CHANGED_ACTION.equals(action)) {
            // Respond to new connection or disconnections


        } else if (WifiP2pManager.WIFI_P2P_THIS_DEVICE_CHANGED_ACTION.equals(action)) {
            // Respond to this device's wifi state changing

            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    deviceListText.setText("device's wifi state changing");
                }
            });

        }
    }
}
