如何在Google搜索小部件中创建弹出式菜单？

我正在创建一个类似于Android的Google搜索部件的部件。如何在Google搜索小部件中创建弹出式菜单？

enter image description here

过得好他们实现上点击过滤器的行动迅速弹出？

这里（用“G”标志的最左边的项目）是它的代码 - 在我的应用程序控件提供者，我有以下 -

Intent activityIntent = new Intent(context, SearchActivity.class); 
Bundle infoBundle = new Bundle(); 
infoBundle.putBoolean(HOME_BUTTON_CLICKED, true); 
activityIntent.putExtras(infoBundle); 
activityIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
PendingIntent homeButtonPI = PendingIntent.getActivity(context, requestCode, activityIntent, PendingIntent.FLAG_UPDATE_CURRENT); 
views.setOnClickPendingIntent(R.id.homeButton, homeButtonPI);

在我SearchActivity我在我的onCreate有这样的（） -

if(bundle.getBoolean(CMWidget.HOME_BUTTON_CLICKED)) { 
    showQuickAction((ImageButton)findViewById(R.id.home_button)); 
}

下面是实际带来的弹出窗口中的showQuickAction（）函数 -

public void showQuickAction(View view){ 
     //populate the quick action 
     quickAction = new QuickAction(view, SearchActivity.this); 
    final ImageButton homeButton = (ImageButton)findViewById(R.id.home_button); 
    final ActionItem quickActionEverything = new ActionItem(); 
    quickActionEverything.setTitle("Everything"); 
    quickActionEverything.setIcon(getResources().getDrawable(R.drawable.logo)); 
    quickActionEverything.setOnClickListener(new OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      quickAction.dismiss(); 

      CONTENT_TYPE = CONTENT_EVERYTHING; 

      homeButton.setImageResource(R.drawable.logo_arrow); 
      searchBox.setHint(R.string.search); 

      if(previousContentType != CONTENT_TYPE && queryString.length() != 0){ 
       emptyListContents(); 
       cancelRunningWSCall(); 
       startSearch(queryString); 
      } 
      else if(queryString.length() != 0) 
       populateList(CONTENT_TYPE); 

      else if(queryString.length() == 0) 
       showRecentSearches(); 

      showSoftKeyboard(); 
      previousContentType = CONTENT_TYPE; 
     } 
    }); 

    final ActionItem quickActionContacts = getQuickActionItem(homeButton, CONTENT_CONTACTS, R.drawable.contacts, R.drawable.contacts_arrow); 
    final ActionItem quickActionMails = getQuickActionItem(homeButton, CONTENT_MAILS, R.drawable.mails, R.drawable.mails_arrow); 
    final ActionItem quickActionCalendars = getQuickActionItem(homeButton, CONTENT_CALENDARS, R.drawable.calendars, R.drawable.calendars_arrow); 
    final ActionItem quickActionDocuments = getQuickActionItem(homeButton, CONTENT_DOCUMENTS, R.drawable.docs, R.drawable.docs_arrow); 


    quickAction.addActionItem(quickActionEverything); 
    quickAction.addActionItem(quickActionMails); 
    quickAction.addActionItem(quickActionCalendars); 
    quickAction.addActionItem(quickActionDocuments); 


    quickAction.show(); 
}

这里是我的堆栈跟踪以及 -

编辑：我搬到了showQuickAction（）函数的onResume（）和还调用onStart（）。没有运气:(

这里还有一个堆栈跟踪 -

他们通过PendingIntent开始正常活动与表示活动应该显示这个子菜单中的动作

你什么时候看到logcat的。点击该按钮：

I/ActivityManager( 167): Starting: Intent { act=com.android.quicksearchbox.action.QSB_AND_SELECT_CORPUS flg=0x14200000 pkg=com.google.android.googlequicksearchbox cmp=com.google.android.googlequicksearchbox/.SearchActivity bnds=[14,86][86,169] (has extras) } from pid -1

，而不是当你点击搜索文本框：

I/ActivityManager( 167): Starting: Intent { act=android.search.action.GLOBAL_SEARCH flg=0x14200000 pkg=com.google.android.googlequicksearchbox cmp=com.google.android.googlequicksearchbox/.SearchActivity bnds=[86,95][384,160] (has extras) } from pid -1

（act=..与意图发送的动作）

编辑到ADRESS新的细节，在这里看到的评论：

我觉得这里的问题是，您尝试从onCreate()打开Quickaction对话框。你的活动在那里准备好了，但还没有看到。如果您现在添加对话框，它会引用它的父级活动并指出它不可见。哪个给你这个错误。尝试将额外的解析和快速操作对话框的创建移至活动生命周期中的稍后时间点。我猜onStart()是这个最好的地方。

好吧，我做了同样的事情。我使用Pending Intent开始了一项活动。在活动中，我调用了一个显示弹出窗口的函数。但是，我的应用程序崩溃了Bad Token异常 - “您的活动正在运行吗？”信息。后来我用了一个线程，延迟了0.5s，然后调用了相同的函数。有用。这延迟的事情有点令人毛骨悚然。有没有其他方法可以解决这个问题？ – Enigma

很难说没有看到代码是诚实的。听起来像某些东西是关闭的，但不能说出什么。对我来说似乎不正常。如果你真的想知道/修复，我会说打开一个新的问题，其中包括与解释和堆栈跟踪的代码。 – 2011-11-28 14:09:24

我用代码更新了这个问题。 – Enigma

这是快速对话框。看看这个example。但首先你应该开始一个活动
