Wi-Fi Direct API를 사용하여 응용 프로그램을 만들려고합니다. 난 2 개 클래스 코드 울부 짖는 소리를 사용하고 'Wi-Fi Direct API를 사용하여 응용 프로그램을 테스트하는 방법
1 클래스 와이파이 다이렉트 :
package com.example.wifi_direct;
import android.net.wifi.p2p.WifiP2pManager;
import android.net.wifi.p2p.WifiP2pManager.Channel;
import android.os.Bundle;
import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.IntentFilter;
import android.view.Menu;
public class WifiDirect extends Activity {
WifiP2pManager mManager;
Channel mChannel;
BroadcastReceiver mReceiver;
IntentFilter mIntentFilter;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//To register the BroadastReceiver
mManager = (WifiP2pManager) getSystemService(Context.WIFI_P2P_SERVICE);
mChannel = (Channel) mManager.initialize(this, getMainLooper(), null); //It was necessary to make a cast (Channel)
mReceiver = new WiFiBroadcastReceiver(mManager, mChannel, this, this);
//To define the filter in the BroadcastReceiver
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);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, 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 - 클래스 WiFiBroadcastReceiver :
package com.example.wifi_direct;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.net.wifi.p2p.WifiP2pManager;
import android.net.wifi.p2p.WifiP2pManager.Channel;
import android.widget.Toast;
/**
* A BroadcastReceiver that notifies of important Wi-Fi p2p events.
*/
public class WiFiBroadcastReceiver extends BroadcastReceiver {
private WifiP2pManager manager;
private Channel channel;
private WifiDirect activity;
//For toast, add also context
private Context context;
public WiFiBroadcastReceiver(WifiP2pManager 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 (WifiP2pManager.WIFI_P2P_STATE_CHANGED_ACTION.equals(action)) {
// Check to see if Wi-Fi is enabled and notify appropriate activity
int state = intent.getIntExtra(WifiP2pManager.EXTRA_WIFI_STATE, -1);
if (state == WifiP2pManager.WIFI_P2P_STATE_ENABLED) {
Toast.makeText(context, "Wi-Fi Direct is enable", Toast.LENGTH_LONG).show();
System.out.print("ddddddddddddddd");
} else {
System.out.print("ddddvvvvvvvdddd");
Toast.makeText(context, "Wi-Fi Direct is not enable", Toast.LENGTH_LONG).show();
}
} else if (WifiP2pManager.WIFI_P2P_PEERS_CHANGED_ACTION.equals(action)) {
// Call WifiP2pManager.requestPeers() to get a list of current peers
} 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
}
}
}
i'am 초보자가이 API를 사용하고 Wi-Fi가 사용되는지 여부를 테스트하는 방법을 알고 싶습니다. (Wi-Fi가 작동하는지 또는하지 않는지 확인하려면 내 활동에서 무엇을해야합니까) 고마워.
