Android 网路判断
判断当前网络是否是wifi
/** * 判断当前是否是wifi * @param mContext * @return */ private 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; } }
一、判断网络连接是否可用
public static boolean isNetworkAvailable(Context context) { ConnectivityManager cm = (ConnectivityManager) context .getSystemService(Context.CONNECTIVITY_SERVICE); if (cm == null) { } else { //如果仅仅是用来判断网络连接 //则可以使用 cm.getActiveNetworkInfo().isAvailable(); NetworkInfo[] info = cm.getAllNetworkInfo(); if (info != null) { for (int i = 0; i < info.length; i++) { if (info[i].getState() == NetworkInfo.State.CONNECTED) { return true; } } } } return false; }
二、判断GPS是否打开
public static boolean isGpsEnabled(Context context) { LocationManager lm = ((LocationManager) context .getSystemService(Context.LOCATION_SERVICE)); List<String> accessibleProviders = lm.getProviders(true); return accessibleProviders != null && accessibleProviders.size() > 0; }
三、判断WIFI是否打开
public static boolean isWifiEnabled(Context context) { ConnectivityManager mgrConn = (ConnectivityManager) context .getSystemService(Context.CONNECTIVITY_SERVICE); TelephonyManager mgrTel = (TelephonyManager) context .getSystemService(Context.TELEPHONY_SERVICE); return ((mgrConn.getActiveNetworkInfo() != null && mgrConn .getActiveNetworkInfo().getState() == NetworkInfo.State.CONNECTED) || mgrTel .getNetworkType() == TelephonyManager.NETWORK_TYPE_UMTS); }
四、判断是否是3G网络
public static boolean is3rd(Context context) { ConnectivityManager cm = (ConnectivityManager) context .getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo networkINfo = cm.getActiveNetworkInfo(); if (networkINfo != null && networkINfo.getType() == ConnectivityManager.TYPE_MOBILE) { return true; } return false; }
五、判断是wifi还是3g网络,用户的体现性在这里了，wifi就可以建议下载或者在线播放。
public static boolean isWifi(Context context) { ConnectivityManager cm = (ConnectivityManager) context .getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo networkINfo = cm.getActiveNetworkInfo(); if (networkINfo != null && networkINfo.getType() == ConnectivityManager.TYPE_WIFI) { return true; } return false; }
