Fragment+FragmentActivity出现The specified child already has a parent. You must call removeView() on the child's parent first.
这个异常是出现在Fragment中的onCreateView方法中初始化布局时发生的。
View view = inflater.inflate(R.layout.fragment3_layout, container);
将上面的那段代码稍微修改一下此异常就解决了。
View view = inflater.inflate(R.layout.fragment3_layout, container,false);
