问题 I'm making some an advanced TabActivity but I need to get every TabView thats in the TabHost . With tabHost.getCurrentTabView() I can get the current TabView but is there a way to get a TabView by its ID? I managed to make a workaround by doing a for loop in the onCreate() method where I go to every tab and put all the View objects in an Array. private View[] tabs; for(int i = 0; i < getTabWidget().getTabCount(); i++) { tabHost.setCurrentTab(i); tabs[i] = tabHost.getCurrentTabView(); } 回答1:

问题 I want to achieve this: What I thought was to make a Custom Toolbar with a bigger height and work with the tabhost and tabpager normally. I have implemented it, but the toolbar is showing the normal height, so it doesn't show as I want, just the top part. Is this the right approach or is it possible to set a TabHost below a Linear/Relative Layout? Because I don't need to work with it as an action bar. Relevant Code toolbar.xml <?xml version="1.0" encoding="utf-8"?> <android.support.v7.widget

问题 I have a Main Drawer activity which loads my fragments when a drawer item is selected. The fragment that is laoded contains a tabhost which hosts multiple fragments so you can switch to via tabs.
