我有一個TabHost有兩個選項卡。每個標籤都有自己的意圖:如何確定當前選定的選項卡?

TabHost.TabSpec spec; // Resusable TabSpec for each tab 
     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, ARActivity.class); 

     // Initialize a TabSpec for each tab and add it to the TabHost 
     spec = tabHost.newTabSpec("trending").setIndicator("Trending",res.getDrawable(R.drawable.icon)).setContent(intent); 
     tabHost.addTab(spec); 

     // Do the same for the other tabs 
     intent = new Intent().setClass(this, WatchlistActivity.class); 
     spec = tabHost.newTabSpec("watchlist").setIndicator("Watchlist",res.getDrawable(R.drawable.icon)).setContent(intent); 
     tabHost.addTab(spec); 

     tabHost.setCurrentTab(0); 

如何確定哪個選項卡時,我在ARActivity或當我在WatchlistActivity選擇?

嗨,你可以使用tabHost.getCurrentTab()onResume()這兩個活動來檢測你選擇了哪個標籤。

但在活動中我沒有參考tabHost ... – 2011-05-06 18:51:33
