下面说一下ListView（GridView）的使用流程：

private void useListView() {
        //绑定View
        listview = (ListView) view.findViewById(R.id.grid_ico);
        //添加头部View
        listview.addHeaderView(headview);
        //添加数据
        mData = new ArrayList<>();
        mData.add(new ListItem(R.mipmap.dot, "这是自定义JavaBean"));
        //添加数据源
        mAdapter = new MyAdapter<ListItem>(mData, R.layout.item_grid_icon) {
            @Override
            public void bindView(ViewHolder holder, ListItem obj) {
                holder.setImageResource(R.id.img_icon, obj.getId());
                holder.setText(R.id.txt_js, obj.getContent());
            }
        };
        //把数据源set进视图
        listview.setAdapter(mAdapter);
        //监听点击事件
        listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                Toast.makeText(getActivity(), "你点击了~" + position + "~项", Toast.LENGTH_SHORT).show();
                switch (position) {
                    case 1:
                        break;
                }
            }
        });
        //监听长按事件
        listview.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
            @Override
            public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
                Toast.makeText(getActivity(), "你长按了第~" + position + "~项", Toast.LENGTH_SHORT).show();
   return true; //默认不处理返回false 
  } 
 });
 }
