如何解决android中的BadTokenException错误？

时间：2011-06-30 12:54:58

标签： android exception android-windowmanager

我开发了一个应用程序，其中有4个选项卡A，B，C，D。每个选项卡都包含一个活动。在第四个选项卡中，DI添加了一个ActivityGroup，其中我还有3个活动X，Y，Z。在我添加了活动组的第四个选项卡中，我收到了StackOverflow错误。请帮我修复此错误。< / p>

这是我的stackTrace： -

这是构建标签的方式------- 

Resources res = getResources();   
TabHost tabHost = getTabHost();  // The activity TabHost
TabHost.TabSpec spec;  // Reusable TabSpec for each tabO
Intent intent;  // Reusable Intent for each tab

// Create an Intent to launch an Activity for the tab (to be reused)

intent = new Intent().setClass(this,FirstActivity.class);
spec = tabHost.newTabSpec("tab_First");
spec.setIndicator("First",res.getDrawable(R.drawable.ic_tab));
spec.setContent(intent);      
tabHost.addTab(spec);

// 2nd tab
intent = new Intent().setClass(this,SecondActivity.class);
spec = tabHost.newTabSpec("tab_Second");
spec.setIndicator("Second",res.getDrawable(R.drawable.ic_tab));
spec.setContent(intent);
tabHost.addTab(spec);

//3rd Tab
intent = new Intent().setClass(this,ThirdActivity.class);
spec = tabHost.newTabSpec("tab_Third");
spec.setIndicator("Third",res.getDrawable(R.drawable.ic_tab));
spec.setContent(intent);
tabHost.addTab(spec);        

// 4th tab    
intent = new Intent().setClass(this,FourthActivity.class);
spec = tabHost.newTabSpec("tab_Fourth");
spec.setIndicator("Fourth",res.getDrawable(R.drawable.ic_create));
spec.setContent(intent);
tabHost.addTab(spec);           

tabHost.setCurrentTab(0);

我没有看到任何Stackoverflow Error（你确定你知道Stackoverflow是什么吗？）...你的问题是，你试图在已经完成的活动中显示一个对话框，或者是不在前台。至少，这是我们可以从您的logcat跟踪中推断出来的。

答案 1 :(得分：1)

正如@Cristian所提到的，我还可以说你正在尝试在活动内部或在当前活动的引用上下文中显示对话框，但是当你在使用带有Tabs的ActivityGroup时应该使用上下文时，那时你需要使用getParent()获取父视图的上下文。

在显示对话框时，您需要父活动的上下文：

  // define at Global level and use it inside the activity whenever you want to refer                
  //activity context;
  private Activity activity;  

  //Write this inside onCreate() method.        
  activity = getParent();

现在，无论何时你应该引用上下文，然后使用这个活动上下文值。

答案 2 :(得分：0)

这是一个常见错误，可以在对话框中使用'getApplicationContext'而不是'this'来修复。另见FATAL EXCEPTION: main。当您（从对话框）尝试使用启动对话框的活动的上下文时，当该活动不再位于前台时，会发生此错误。

答案 3 :(得分：-1)

您在创建选项卡的位置创建静态上下文并使用您要在其中创建对话框的任何活动位置
