亲测Android wifi状态三种广播

测试代码

public class NetworkConnectChangedReceiver extends BroadcastReceiver{
    @Override
    public void onReceive(Context context, Intent intent) {
    if (WifiManager.WIFI_STATE_CHANGED_ACTION.equals(intent.getAction())) {//这个监听wifi的打开与关闭，与wifi的连接无关
            int wifiState = intent.getIntExtra(WifiManager.EXTRA_WIFI_STATE, 0);
            LogTag.showTAG_e("WIFI状态", "wifiState"+wifiState);
            switch (wifiState) {
            case WifiManager.WIFI_STATE_DISABLED:
                break;
            case WifiManager.WIFI_STATE_DISABLING:
                break;
           //...
            }
        }
    // 这个监听wifi的连接状态即是否连上了一个有效无线路由，当上边广播的状态是WifiManager.WIFI_STATE_DISABLING，和WIFI_STATE_DISABLED的时候，根本不会接到这个广播。
    // 在上边广播接到广播是WifiManager.WIFI_STATE_ENABLED状态的同时也会接到这个广播，当然刚打开wifi肯定还没有连接到有效的无线
    if (WifiManager.NETWORK_STATE_CHANGED_ACTION.equals(intent.getAction())) {
            Parcelable parcelableExtra = intent.getParcelableExtra(WifiManager.EXTRA_NETWORK_INFO);
            if (null != parcelableExtra) {

                State state = networkInfo.getState();
                boolean isConnected = state==State.CONNECTED;//当然，这边可以更精确的确定状态
                LogTag.showTAG_e(this.getClass().getSimpleName(), "isConnected"+isConnected);
                if(isConnected){
                }else{

                }
            }
        }
    //这个监听网络连接的设置，包括wifi和移动数据的打开和关闭。.
        //最好用的还是这个监听。wifi如果打开，关闭，以及连接上可用的连接都会接到监听。见log
        // 这个广播的最大弊端是比上边两个广播的反应要慢，如果只是要监听wifi，我觉得还是用上边两个配合比较合适
    if(ConnectivityManager.CONNECTIVITY_ACTION.equals(intent.getAction())){
        NetworkInfo info = intent.getParcelableExtra(ConnectivityManager.EXTRA_NETWORK_INFO);
        if (info != null) {

            LogTag.showTAG_e("CONNECTIVITY_ACTION", "getSubtypeName()"+info.getSubtypeName());
            LogTag.showTAG_e("CONNECTIVITY_ACTION", "getState()"+info.getState());
            LogTag.showTAG_e("CONNECTIVITY_ACTION",
                                "getDetailedState()"+info.getDetailedState().name());

最终监听wifi提示的代码

if (WifiManager.NETWORK_STATE_CHANGED_ACTION.equals(intent.getAction())) {// 这个监听wifi的连接状态
           Parcelable parcelableExtra = intent.getParcelableExtra(WifiManager.EXTRA_NETWORK_INFO);
           if (null != parcelableExtra) {
               NetworkInfo networkInfo = (NetworkInfo) parcelableExtra;
               State state = networkInfo.getState();
               if(state==State.CONNECTED){
                showWifiCconnected(context);
               }
               /**else if(state==State.DISCONNECTED){
                showWifiDisconnected(context);
               }*///昨天写的这个方法，在坐地铁的时候发现，如果地铁上有无效的wifi站点，手机会自动连接，但是连接失败后还是会接到广播，所以不能用了
           }
       }
if(ConnectivityManager.CONNECTIVITY_ACTION.equals(intent.getAction())){//这个监听网络连接的设置，包括wifi和移动数据 的打开和关闭
NetworkInfo info = intent.getParcelableExtra(ConnectivityManager.EXTRA_NETWORK_INFO);
if (info != null) {
    if(NetworkInfo.State.CONNECTED==info.getState()){
        Intent pushIntent = new Intent();
        pushIntent.setClass(context, NotificationService.class);
    }else if(info.getType()==1){
            if(NetworkInfo.State.DISCONNECTING==info.getState())
                showWifiDisconnected(context);
