使用这种扫描可用的WiFi

import java.util.List; 
import android.app.Activity; 
import android.content.BroadcastReceiver; 
import android.content.Context; 
import android.content.Intent; 
import android.content.IntentFilter; 
import android.net.wifi.ScanResult; 
import android.net.wifi.WifiManager; 
import android.os.Bundle; 
import android.view.Menu; 
import android.view.MenuItem; 
import android.widget.TextView; 

public class Test_allActivity extends Activity { 

TextView mainText; 
WifiManager mainWifi; 
WifiReceiver receiverWifi; 
List<ScanResult> wifiList; 
StringBuilder sb = new StringBuilder(); 

public void onCreate(Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
    mainText = (TextView) findViewById(R.id.mainText); 
    mainWifi = (WifiManager) getSystemService(Context.WIFI_SERVICE); 
    receiverWifi = new WifiReceiver(); 
    registerReceiver(receiverWifi, new IntentFilter(
    WifiManager.SCAN_RESULTS_AVAILABLE_ACTION)); 
    mainWifi.startScan(); 
    mainText.setText("\nStarting Scan...\n"); 
} 

public boolean onCreateOptionsMenu(Menu menu) { 
menu.add(0, 0, 0, "Refresh"); 
return super.onCreateOptionsMenu(menu);} 
public boolean onMenuItemSelected(int featureId, MenuItem item) { 
    mainWifi.startScan(); 
    mainText.setText("Starting Scan"); 
    return super.onMenuItemSelected(featureId, item);} 
protected void onPause() { 
    unregisterReceiver(receiverWifi); 
    super.onPause(); 
} 
/* 
protected void onResume() { 
    registerReceiver(receiverWifi, new IntentFilter(
    WifiManager.SCAN_RESULTS_AVAILABLE_ACTION)); 
    super.onResume(); 
}*/ 

class WifiReceiver extends BroadcastReceiver { 
    public void onReceive(Context c, Intent intent) { 
    sb = new StringBuilder(); 
    wifiList = mainWifi.getScanResults(); 
    for(int i = 0; i < wifiList.size(); i++){ 
    sb.append(new Integer(i+1).toString() + "."); 
    sb.append((wifiList.get(i)).toString()); 
    sb.append("\n"); 
} 
mainText.setText(sb); 
} 
    }} 

给这个权限在AndroidManifest.xml中文件

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission> 
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>
