如果wifi网络在android中不可用,有人可以告诉我如何向用户发送通知吗?有人可以提供例子吗?
谢谢
最佳答案
Here is a tutorial to do this, it can do these things:
设备上是否可以使用WiFi
WiFi是否启用WiFi
连接到接入点
要点是:
private class ConnectionChangeReceiver extends BroadcastReceiver {
public void onReceive( Context context, Intent intent ) {
Log.d(tag, "Inside Broadcast Reciever");
CheckWifiStatus();
}
}
private void RegisterWifiWatcher()
{
if(wifiWatcher == null)
wifiWatcher = new ConnectionChangeReceiver();
IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(WifiManager.NETWORK_STATE_CHANGED_ACTION);
intentFilter.addAction(WifiManager.SUPPLICANT_CONNECTION_CHANGE_ACTION);
intentFilter.addAction(WifiManager.WIFI_STATE_CHANGED_ACTION);
intentFilter.addAction(WifiManager.SUPPLICANT_STATE_CHANGED_ACTION);
registerReceiver(wifiWatcher, intentFilter);
}
