您可以通過使用這個類互聯網連接狀態變化(剛加入這個類,因爲它是)
public class NetworkStateReceiver extends BroadcastReceiver {
protected List<NetworkStateReceiverListener> listeners;
protected Boolean connected;
public NetworkStateReceiver() {
listeners = new ArrayList<NetworkStateReceiverListener>();
connected = null;
}
public void onReceive(Context context, Intent intent) {
if(intent == null || intent.getExtras() == null)
return;
ConnectivityManager manager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo ni = manager.getActiveNetworkInfo();
if(ni != null && ni.getState() == NetworkInfo.State.CONNECTED) {
connected = true;
} else if(intent.getBooleanExtra(ConnectivityManager.EXTRA_NO_CONNECTIVITY,Boolean.FALSE)) {
connected = false;
}
notifyStateToAll();
}
private void notifyStateToAll() {
for(NetworkStateReceiverListener listener : listeners)
notifyState(listener);
}
private void notifyState(NetworkStateReceiverListener listener) {
if(connected == null || listener == null)
return;
if(connected == true)
listener.networkAvailable();
else
listener.networkUnavailable();
}
public void addListener(NetworkStateReceiverListener l) {
listeners.add(l);
notifyState(l);
}
public void removeListener(NetworkStateReceiverListener l) {
listeners.remove(l);
}
public interface NetworkStateReceiverListener {
public void networkAvailable();
public void networkUnavailable();
}
}
當過互聯網連接改爲呼籲廣告

我想,你的代碼需要返工或實施anoth當它遍歷你的代碼時,它的功能就是做基本的控制檢查。你告訴我們的方式在代碼中聽起來有些雜亂。 – user7568042
