我有一个使用以下代码注册观察者的 Activity
Activity :
//Register for network status updates
NetworkStatus networkStatus = new NetworkStatus(this);
networkStatus.addObserver(new OfflineActivity());
Thread thread = new Thread(networkStatus);
thread.run();
学科:
@Override
public void run() {
for(;;) {
Log.d("NetworkStatus", "Checking Network Status");
if(isConnectedToInternet(context)){
notifyObservers();
Log.d("NetworkStatus", "Network Connection is established");
}
else {
Log.d("NetworkStatus", "Not connected to network");
}
}
}
当我单击该 Activity 时,该程序将变得无响应。。有什么想法吗?
最佳答案
您应该使用.start();
Thread thread = new Thread(networkStatus);
thread.start();
当您显式调用run方法时,它实际上不会产生新的线程,而是该方法调用仍在UI线程中运行。
