android获取及监听手机网络状态
作者:he先森
大家好,本篇文章主要讲的是android获取及监听手机网络状态,感兴趣的同学赶快来看一看吧,对你有帮助的话记得收藏一下,方便下次浏览
一、获取当前手机联网方式是WiFi还是手机4G数据
private boolean getNetworkType(){ ConnectivityManager mConnectivity = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE); //检查网络链接 NetworkInfo info = mConnectivity.getActiveNetworkInfo(); int netType = mConnectivity.getActiveNetworkInfo().getType(); if (netType == ConnectivityManager.TYPE_WIFI) { //WIFI ChangYouLog.i(TAG,"当前是WIFI连接 isConnected = "+info.isConnected()); return info.isConnected(); } else if (netType == ConnectivityManager.TYPE_MOBILE) { //MOBILE ChangYouLog.i(TAG,"当前是手机网络连接 isConnected = "+info.isConnected()); return info.isConnected(); } else { ChangYouLog.i(TAG,"当前没有网络连接 isConnected = "+info.isConnected()); return false; } }
二、监听手机网络变化
private class MyBroadcastReceiver extends BroadcastReceiver{ @Override public void onReceive(Context context, Intent intent) { if (intent.getAction().equals(ConnectivityManager.CONNECTIVITY_ACTION)) {//监听网络连接 //获取联网状态的NetworkInfo对象 NetworkInfo info = intent.getParcelableExtra(ConnectivityManager.EXTRA_NETWORK_INFO); if (info != null) { //如果当前的网络连接成功并且网络连接可用 if (NetworkInfo.State.CONNECTED == info.getState() && info.isAvailable()) { if (info.getType() == ConnectivityManager.TYPE_WIFI){ ChangYouLog.i(TAG,"连接上WiFi"); }else if (info.getType() == ConnectivityManager.TYPE_MOBILE){ ChangYouLog.i(TAG,"连接上移动网络数据"); CYouLbyMicroClient.getInstance().gameEvent("Network_4G_reminder"); } } else { ChangYouLog.i(TAG,"网络断开"); } } } } }
注:需要添加网络状态权限
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
