代码如下：
枚举
public enum HOTSPOT {// 正在关闭WIFI_AP_STATE_DISABLING(10),// 已关闭WIFI_AP_STATE_DISABLED(11),// 正在开启WIFI_AP_STATE_ENABLING(12),// 已开启WIFI_AP_STATE_ENABLED(13),//错误状态WIFI_AP_STATE_FAILED(14);private int value;public int getValue() {return value;}public void setValue(int value) {this.value = value;}HOTSPOT(int value) {this.value = value;}public static HOTSPOT getType(int value) {for (HOTSPOT hotspot : HOTSPOT.values()) {if (hotspot.getValue() == value) {return hotspot;}}return null;}
}
监听
public class NetworkBroadcastReceiver extends BroadcastReceiver {@Overridepublic void onReceive(Context context, Intent intent) {if (intent.getAction().equals(ConnectivityManager.CONNECTIVITY_ACTION)) {NetworkInformation.sharedManager().setContext(context);}}
}
