Android Wi-Fi Direct：onPeersAvailable

我正在开发一个基于WiFi Direct for Android的简单应用程序,它必须连接两个设备.为此,我需要调用funciónonPeersAvailable(myPeerListListener),但我不知道如何.

我的应用程序有这两个元素：

1主要活动：

package android.nacho.WifiDirect;



import android.net.wifi.p2p.@L_626_3@manager.ChAnnel;

import android.net.wifi.p2p.@L_626_3@manager;
import android.os.bundle;
import android.app.Activity;
import android.content.broadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.view.Menu;
import android.view.View;
import android.view.View.onClickListener;
import android.widget.button;
import android.widget.TextView;

public class WifiDirect extends Activity {


    @L_626_3@manager mManager;
    ChAnnel mChAnnel;
    BroadcastReceiver mReceiver;

    IntentFilter mIntentFilter;

    @Override
    public void onCreate(Bundle savedInstanceStatE) {

        super.onCreate(savedInstanceStatE);
        setContentView(R.layout.activity_wifi_direct);


        //To register the BroadastReceiver
        mManager = (@L_626_3@manager) getSystemservice(Context.WIFI_P2P_serviCE);
        mChAnnel =   mManager.initialize(this,getMainLooper(),null); //It was necessary to make a cast (ChAnnel)
        mReceiver = new WiFiBroadcastReceiver(mManager,mChAnnel,this); //,this);

        //Layout
        final Button btnScan = (Button)findViewById(R.id.btnScan); 
        final TextView TextDebug=(TextView)findViewById(R.id.TextDebug);


        //To define the filter in the BroadcastReceiver
        mIntentFilter = new IntentFilter();
        mIntentFilter.addAction(@L_626_3@manager.WIFI_P2P_STATE_CHANGED_ACTION);
        mIntentFilter.addAction(@L_626_3@manager.WIFI_P2P_PEERS_CHANGED_ACTION);
        mIntentFilter.addAction(@L_626_3@manager.WIFI_P2P_CONNECTION_CHANGED_ACTION);
        mIntentFilter.addAction(@L_626_3@manager.WIFI_P2P_THIS_DEVICE_CHANGED_ACTION);




        final OnClickListener ScanListener=new OnClickListener() //Sacado de TEstPsycologico
        {
            public void onClick(View v){



                TextDebug.setText("SE intentan buscar Peers");

                mManager.discoverPeers(mChAnnel,new @L_626_3@manager.ActionListener() {


                    public void onsuccess() {

                        TextDebug.setText("Ha habido éxito buscando Peers");//DEBUG: Para ver si es posible encontrar Peers

                    }


                    public void onFailure(int reasonCodE) {

                        TextDebug.setText("Algo ha salido mal buscando Peers"); //DEBUG: Para ver si pasó algo raro busando Peers
                    }
                });


                onPeersAvailable(myPeerListListener);

            }


        };

        btnScan.setOnClickListener(ScanListener);

    }


    @Override
    public Boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_wifi_direct,menu);
        return true;
    }

    //


    @Override
    protected void onResume() {
        super.onResume();
        registerReceiver(mReceiver,mIntentFilter);
    }

   // unregister the broadcast receiver
    @Override
    protected void onPause() {
        super.onPause();
        unregisterReceiver(mReceiver);
    }

}

2类BroadcastReceiver：

package android.nacho.WifiDirect;

import android.net.wifi.p2p.@L_626_3@manager.ChAnnel;
import android.net.wifi.p2p.@L_626_3@manager.PeerListListener;

import android.content.broadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.net.wifi.p2p.@L_626_3@manager;
import android.widget.Toast;



/**
 * A BroadcastReceiver that notifies of important Wi-Fi p2p events.
 */

public class WiFiBroadcastReceiver extends BroadcastReceiver {

    private @L_626_3@manager manager;
    private ChAnnel chAnnel;
    private WifiDirect activity;
    private PeerListListener myPeerListListener;

    //For toast,add also context
    //private Context context;

    public WiFiBroadcastReceiver(@L_626_3@manager manager,ChAnnel chAnnel,WifiDirect activity){//,Context context) {

        super();
        this.manager = manager;
        this.chAnnel = chAnnel;
        this.activity = activity;
       // this.context= context;
    }

    @Override
    public void onReceive(Context context,Intent intent) {

        String action = intent.getAction();     


        if (@L_626_3@manager.WIFI_P2P_STATE_CHANGED_ACTION.equals(action)) {

            // check to see if Wi-Fi is enabled and notify appropriate activity
             int state = intent.getIntextra(@L_626_3@manager.EXTRA_WIFI_STATE,-1);
             if (state == @L_626_3@manager.WIFI_P2P_STATE_ENABLED) {

                //Toast.makeText(context,"Wi-Fi Direct is enable",Toast.LENGTH_LONG).show();

             } else {

                //Toast.makeText(context,"Wi-Fi Direct is not enable",Toast.LENGTH_LONG).show();
             }      

        } else if (@L_626_3@manager.WIFI_P2P_PEERS_CHANGED_ACTION.equals(action)) {
            // Call @L_626_3@manager.requestPeers() to get a list of current peers

             // 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,myPeerListListener);
                 manager.onPeersAvailable(myPeerListListener);

            }



        } else if (@L_626_3@manager.WIFI_P2P_CONNECTION_CHANGED_ACTION.equals(action)) {
            // Respond to new connection or disconnections
        } else if (@L_626_3@manager.WIFI_P2P_THIS_DEVICE_CHANGED_ACTION.equals(action)) {
            // Respond to this device's wifi state changing
        }
    }
}

到目前为止,我的代码应该能够检测运行应用程序的设备周围的对等体,哪个ID应该存储在变量myPeerListListener中.所有这些都发生在名为OnReceiv()的BroadcastReceiver方法的第二个意图中,通过调用：

@H_206_6@manager.requestPeers(chAnnel,myPeerListListener);

现在我想操纵那个列表.因此,根据API信息,它应该调用requestPeers,您可以在此处查看API：

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

*发现同行的部分

所以我试过的是在下面打电话给：

@H_206_6@manager.onPeersAvailable(myPeerListListener);

但我得到这个错误：

对于@L_626_3@manager类型,未定义onPeersAvailable(@L_626_3@manager.PeerListListener)方法

谁能告诉我怎样才能将PeerListListener正确发送到主活动？

非常感谢您的宝贵时间
