Fragment怎么获得Activity的控件：

rootview = getActivity().getWindow().getDecorView();search_flowLayout = (FlowLayout)view.findViewById(R.id.search_flowLayout);

Fragment之间切换

AnotherRightFragment fragment = new AnotherRightFragment();FragmentManager fragmentManager = getFragmentManager();FragmentTransaction transaction = fragmentManager.beginTransaction();transaction.replace(R.id.right_layout, fragment);   //切记，right_layout是fragment的父布局transaction.addToBackStack(null);transaction.commit();

在Activity中获取另一个xml布局的元素

LayoutInflater layout=this.getLayoutInflater();View view=layout.inflate(R.layout.login_stytle, null);Button b=(Button)view.findViewById(R.id.b);

给listview加头部

LinearLayout header = (LinearLayout) inflater.inflate(R.layout.search_listview_header,null);search_history_list.addHeaderView(header,null,false); //第三个参数表示头部不可选择
