检查Android中的wifi网络

我想通过点击一个名为“保存”的按钮将数据存储在服务器中，当我按下该按钮时，我想检查wifi是否可用我应该能够保存数据，否则检查数据连接如果没有平衡，那么我应该得到一条错误消息“没有互联网”，否则保存数据我怎么做

ConnectivityManager connManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo mWifi = connManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);

if (mWifi.isConnected()) {
    // Do whatever
}

您需要添加权限：

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

如果要检查设备是否连接了wifi，请使用此方法

public static boolean isInternetConnected(Context context) {
    ConnectivityManager connManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo mnetwork = connManager.getActiveNetworkInfo();
    return mnetwork != null && mnetwork.isConnected();
}

public static boolean isMobileInternetConnected(Context context) {
        ConnectivityManager connManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo mNetwork = connManager.getActiveNetworkInfo();
        return mNetwork != null && mNetwork.isConnected() && mNetwork.getType() == ConnectivityManager.TYPE_MOBILE;
    }

如果您想检查您的设备是否已连接到移动网络Internet，请使用此方法

public static boolean isInternetConnected(Context context) {
    ConnectivityManager connManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo mnetwork = connManager.getActiveNetworkInfo();
    return mnetwork != null && mnetwork.isConnected();
}

public static boolean isMobileInternetConnected(Context context) {
        ConnectivityManager connManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo mNetwork = connManager.getActiveNetworkInfo();
        return mNetwork != null && mNetwork.isConnected() && mNetwork.getType() == ConnectivityManager.TYPE_MOBILE;
    }

注意：不要忘记添加权限

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
