我有一个有两个标签的TabHost。每个标签都有自己的意图:

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);

当我处于ARActivity或我在WatchlistActivity时,如何确定选择了哪个标签?

您可以使用活动的tabHost.getCurrentTab()onResume()来检测您选择的选项卡。
