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