问题 I created an App that uses Google Maps to get the users current location and draw routes. Recently I converted this app to a TabHost with five tabs. Because of this I now need a way to clear and restart the map whenever a user clicks on that tab. How can I do this. Below is the layout.xml and activity code for my map. activity_map_view.xml <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android

问题 Hi I have a problem with my tabhost and I don't really understand why. My tab host contains 4 listviews and shows a list in each tab. Sometimes when I change the tab (click on new tab) the content doesn't change or it freezes.

问题 I see some answers here prefer views over activities as contents of tabs. Correct me if I am wrong. My understanding is that by switching out views, it's possible to keep the navigation flow inside a tab (more user friendly, I think). But I wonder how to manage the view stack then in case of the back button events. Also this could cause one giant Activity with large amount of views, which might not be good. So I wish to know why exactly views as contents is preferred before I change my

问题 I'd like to show a different fragment in a TabHost, for every tab. But it seems that there's no easy way to do this. TabHost can only accept A. Views or B. Intents that launch Activities when the user selects a tab. Going with A means that I have to initialize every fragment and load them into container Views that are given to the TabHost.

Depending on which tab you select it shows a different listview: I wish to achieve this exact same thing. I tried doing it with TabHost widget, but for the life of me I couldn't get rid of the title bar (I tried
