判斷當(dāng)前網(wǎng)絡(luò)是否是wifi

/**
* 判斷當(dāng)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、判斷網(wǎng)絡(luò)連接是否可用
public static boolean isNetworkAvailable(Context context) {
ConnectivityManager cm = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
if (cm == null) {
} else {
//如果僅僅是用來判斷網(wǎng)絡(luò)連接
//則可以使用 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、判斷GPS是否打開
public static boolean isGpsEnabled(Context context) {
LocationManager lm = ((LocationManager) context
.getSystemService(Context.LOCATION_SERVICE));
List accessibleProviders = lm.getProviders(true);
return accessibleProviders != null && accessibleProviders.size() > 0;
}
三、判斷WIFI是否打開
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、判斷是否是3G網(wǎng)絡(luò)
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、判斷是wifi還是3g網(wǎng)絡(luò),用戶的體現(xiàn)性在這里了，wifi就可以建議下載或者在線播放。
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;
}
