问题 I'm trying to put a FragmentTabHost at the bottom of the screen. Time ago, I was able to do that with regular TabHost (following this thread), but now this is not working for me. Is there a way to do that? Thanks! 回答1: I finally got to the bottom of this. There is an issue with FragmentTabHost.java which will always create a TabHost element for you, no matter what you define in XML and inflate beforehand. As such, I commented out that part of code when writing my own version of
