请问广播接受者不能发送广播吗？还是我写的代码有问题啊？
public class netReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Intent wifi = new Intent();
if(isWifi(context)){
wifi = new Intent(context, MyService.class);
context.startService(intent);
}else{
wifi.setAction("net.s5c.Changelink.wifiOff");
sendBroadcast(wifi);
}
Toast.makeText(context, "监听到WIFI动作", Toast.LENGTH_LONG).show();
}
public static boolean isWifi(Context mContext) {
ConnectivityManager connectivityManager = (ConnectivityManager) mContext
.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetInfo = connectivityManager.getActiveNetworkInfo();
if (activeNetInfo != null
&& activeNetInfo.getType() == ConnectivityManager.TYPE_WIFI) {
return true;
}
return false;
}
}

import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.net.ConnectivityManager; import android.net.NetworkInfo; public class netReceiver extends BroadcastReceiver { Intent wifi = new Intent(); @SuppressWarnings("static-access") public void onReceive(Context context, Intent intent) { ConnectivityManager manager = (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo activeNetInfo = manager.getActiveNetworkInfo(); if (activeNetInfo != null && activeNetInfo.getType() == manager.TYPE_WIFI) { wifi = new Intent(context, MyService.class); wifi.setAction(MainActivity.ACCESSIBILITY_SERVICE); context.startService(wifi); }else{ wifi.setAction("net.s5c.Changelink.wifiOff"); context.sendBroadcast(wifi); } } }我又重写了一下，发现广播接收者多次接到广播还是不能启动起来服务，我知道我写的有问题，但那里有问题应该怎么写啊？？
