7个按钮，3个AsyncTasks，1个活动，还有一个噩梦

-4

就在我以为我有这个收藏的时候，我意识到我只能使用活动中的按钮按照它们写在Activity.java中的相同顺序例如：不能执行按钮5按下，直到1,2,3和4全部按下！）我该如何解决这个问题？7个按钮，3个AsyncTasks，1个活动，还有一个噩梦

Activity.Java：

public class TwoActivity extends Activity {

两个长码片断，一个难以理解的问题描述，你的问题！ ;-) – Knickedi

为什么不创建一个可以做4种不同类型下载的异步类？这个类将作为参数：按钮，textview和url。那么你有四分之一的代码。在异步中，使所有按钮不可点击（setClickable（false））。

无论如何，您需要为OnCreate（）中的所有按钮分配一个onclicklistener。您可以创建自定义类并切换按钮类型，或者仅执行个性化的匿名类路由。

林猜测我将不得不使异步一个单独的类，然后让它按钮上按下按钮。但是，如何实现四种不同的下载？ “如果”陈述？ – jb15613

您目前已拥有支持多个网址的功能。当你在async任务上调用execute（）时，你会传递一个url。只需更改此网址每个按钮。 – Ian

您需要重写onCreateOptionsMenu方法。我给你的示例代码：

@Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
    menu.add(group1Id,searchBtnId ,searchBtnId,"Search"); 
    menu.add(group2Id,scheduleBtnId ,scheduleBtnId,R.string.schedule); 
    menu.add(group2Id,playBtnId ,playBtnId,"Play"); 
    menu.add(group2Id,stopBtnId ,stopBtnId,R.string.stop); 
    return super.onCreateOptionsMenu(menu); 
    }
