android编程实现设置、打开wifi热点共享供他人连接的方法

import android.net.wifi.WifiManager; import android.os.Bundle;

public class MainActivity extends Activity { private List<ScanResult> wifiList;

private WifiManager wifiManager; private List<String> passableHotsPot;

private WifiReceiver wifiReceiver; private boolean isConnected=false;

private Button connect; @Override

public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);

init(); }

/* 初始化参数 */ public void init() {

setContentView(R.layout.main); connect=(Button)findViewById(R.id.connect);

wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE); wifiReceiver = new WifiReceiver();

//通过按钮事件搜索热点 connect.setOnClickListener(new View.OnClickListener() {

@Override public void onClick(View v) {

wifiManager.startScan(); }

}); }

/* 监听热点变化 */ private final class WifiReceiver extends BroadcastReceiver {

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

wifiList = wifiManager.getScanResults(); if (wifiList == null || wifiList.size() == 0 || isConnected)

return; onReceiveNewNetworks(wifiList);

} }

/*当搜索到新的wifi热点时判断该热点是否符合规格*/ public void onReceiveNewNetworks(List<ScanResult> wifiList){

passableHotsPot=new ArrayList<String>(); for(ScanResult result:wifiList){

System.out.println(result.SSID); if((result.SSID).contains("YRCCONNECTION"))

passableHotsPot.add(result.SSID); }

synchronized (this) { connectToHotpot();
