Android：互联网连接更改监听器

尝试这个

public class NetworkUtil {    public static final int TYPE_WIFI = 1;    public static final int TYPE_MOBILE = 2;    public static final int TYPE_NOT_ConNECTED = 0;    public static final int NETWORK_STATUS_NOT_ConNECTED = 0;    public static final int NETWORK_STATUS_WIFI = 1;    public static final int NETWORK_STATUS_MOBILE = 2;    public static int getConnectivityStatus(Context context) {        ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);        NetworkInfo activeNetwork = cm.getActiveNetworkInfo();        if (null != activeNetwork) { if(activeNetwork.getType() == ConnectivityManager.TYPE_WIFI)     return TYPE_WIFI; if(activeNetwork.getType() == ConnectivityManager.TYPE_MOBILE)     return TYPE_MOBILE;        }         return TYPE_NOT_CONNECTED;    }    public static int getConnectivityStatusString(Context context) {        int conn = NetworkUtil.getConnectivityStatus(context);        int status = 0;        if (conn == NetworkUtil.TYPE_WIFI) { status = NETWORK_STATUS_WIFI;        } else if (conn == NetworkUtil.TYPE_MOBILE) { status = NETWORK_STATUS_MOBILE;        } else if (conn == NetworkUtil.TYPE_NOT_CONNECTED) { status = NETWORK_STATUS_NOT_CONNECTED;        }        return status;    }}

对于广播接收器

public class NetworkChangeReceiver extends BroadcastReceiver {    @Override    public void onReceive(final Context context, final Intent intent) {        int status = NetworkUtil.getConnectivityStatusString(context);        Log.e("Sulod sa network reciever", "Sulod sa network reciever");        if ("android.net.conn.CONNECTIVITY_CHANGE".equals(intent.getAction())) { if (status == NetworkUtil.NETWORK_STATUS_NOT_CONNECTED) {     new ForceExitPause(context).execute(); } else {     new ResumeForceExitPause(context).execute(); }       }    }}

不要忘记将其放入你的AndroidManifest.xml

 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.INTERNET" /> <receiver        android:name="NetworkChangeReceiver"        android:label="NetworkChangeReceiver" >        <intent-filter> <action android:name="android.net.conn.CONNECTIVITY_CHANGE" /> <action android:name="android.net.wifi.WIFI_STATE_CHANGED" />        </intent-filter>    </receiver>

希望这会为你加油！
