Android静态注册广播receiver检测WIFI连接状况变化

在AndroidManifest.xml静态注册一个receiver，增加对WiFi状态变化时候Android系统发送的广播事件过滤器，从而达到监听、检测WiFi状态变化。

完成相关广播接收器：

package zhangphil.wifi;

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

import android.net.NetworkInfo;

import android.net.wifi.WifiInfo;

import android.net.wifi.WifiManager;

import android.util.Log;

public class WIFIStateChangedBroadcastReceiver extends BroadcastReceiver {

private final String tag = "WIFI链接状况";

@Override

public void onReceive(Context context, Intent intent) {

if (intent.getAction().equals(WifiManager.NETWORK_STATE_CHANGED_ACTION)) {

NetworkInfo info = intent.getParcelableExtra(WifiManager.EXTRA_NETWORK_INFO);

if (info.getState().equals(NetworkInfo.State.CONNECTED)) {

WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);

WifiInfo wifiInfo = wifiManager.getConnectionInfo();

// 当前WIFI名称

Log.d(tag, "连接到WIFI " + wifiInfo.getSSID());

}

}

if (intent.getAction().equals(WifiManager.WIFI_STATE_CHANGED_ACTION)) {

int wifistate = intent.getIntExtra(WifiManager.EXTRA_WIFI_STATE, WifiManager.WIFI_STATE_DISABLED);

if (wifistate == WifiManager.WIFI_STATE_DISABLED) {

Log.d(tag, "WIFI关闭");

}

if (wifistate == WifiManager.WIFI_STATE_ENABLED) {

Log.d(tag, "WIFI开启");

}

}

}

}
