如何在不锁定Android应用程序用户界面的情况下等待10秒 [英] How can I wait for 10 second without locking application UI in android

问题描述

我遇到了问题，我想等待10秒，因为我希望我的应用程序在那10秒钟后启动下面的代码，但又不阻止该人单击应用程序中的其他任何内容(没有 >调用Thread.sleep();).

I am stuck with a problem, I want to wait 10 second because I want my application to start the code below after that 10 sec but without stopping that person from clicking anything else in the application (without calling Thread.sleep();).

try {
    Log.v("msg", "WAIT CheckFrequencyRun");
    Thread.sleep(10000); // giving time to connect to wifi
    
   } catch (InterruptedException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   }
   //if no network
   if(wifiManager.getConnectionInfo().getNetworkId()==-1){
    //stop wifi
    wifiManager.setWifiEnabled(false);
    Log.v("msg", "no connection");
    handler.postDelayed(this, checkInterval);
   }
   //else connection
   else{
    Log.v("msg", "connection");
    onDestroy();
   }

推荐答案

您永远不想在UI线程上调用thread.sleep()，因为听起来您已经弄清楚了.这冻结了UI，始终是一件坏事.您可以使用单独的Thread和postDelayed

You never want to call thread.sleep() on the UI thread as it sounds like you have figured out. This freezes the UI and is always a bad thing to do. You can use a separate Thread and postDelayed
