Android仿天猫二级分类_二级分类ExpandableListView源代码

本Demo是一款有多种二级菜单的项目、有类似美团上的美食购物分类、有类似QQ分组的、有listview里面嵌套gridview的、几乎项目中个能用到的二级菜单这里都有

而且界面还是比较简洁的、很实用、又得直接可以在项目中应用、项目代码量也不是很多、而且都有详细的分层、项目中重要的部分也都有详细的注释、本项目采用UTF-8编码、运行效果如下

ListView 部分源代码

private void initView() {
    mainlist = (ListView) findViewById(R.id.classify_mainlist);
    morelist = (ListView) findViewById(R.id.classify_morelist);
    mainAdapter = new ClassifyMainAdapter(ListListActivity.this, mainList);
    mainAdapter.setSelectItem(0);
    mainlist.setAdapter(mainAdapter);

    mainlist.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view,
                int position, long id) {
            initAdapter(Model.MORELISTTXT[position]);
            mainAdapter.setSelectItem(position);
            mainAdapter.notifyDataSetChanged();
        }
    });
    mainlist.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
    // 一定要设置这个属性，否则ListView不会刷新
    initAdapter(Model.MORELISTTXT[0]);

    morelist.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view,
                int position, long id) {
            moreAdapter.setSelectItem(position);
            moreAdapter.notifyDataSetChanged();
        }
    });
}

ExpandableListView部分代码

private void setListener() {
    expandableListView.setOnGroupClickListener(new OnGroupClickListener() {

        @Override
        public boolean onGroupClick(ExpandableListView parent, View v,
                int groupPosition, long id) {
            return false;
        }
    });

    expandableListView.setOnChildClickListener(new OnChildClickListener() {

        @Override
        public boolean onChildClick(ExpandableListView parent, View v,
                int groupPosition, int childPosition, long id) {
            Toast.makeText(getApplicationContext(),
                    child_text_array[groupPosition][childPosition],
                    Toast.LENGTH_SHORT).show();
            return false;
        }
    });
}

ExpandableGridView部分代码

private void setListener() {
    expandableGridView.setOnGroupClickListener(new OnGroupClickListener() {

        @Override
        public boolean onGroupClick(ExpandableListView parent, View v,
                int groupPosition, long id) {
            if (sign == -1) {
                // 展开被选的group
                expandableGridView.expandGroup(groupPosition);
                // 设置被选中的group置于顶端
                expandableGridView.setSelectedGroup(groupPosition);
                sign = groupPosition;
            } else if (sign == groupPosition) {
                expandableGridView.collapseGroup(sign);
                sign = -1;
            } else {
                expandableGridView.collapseGroup(sign);
                // 展开被选的group
                expandableGridView.expandGroup(groupPosition);
                // 设置被选中的group置于顶端
                expandableGridView.setSelectedGroup(groupPosition);
                sign = groupPosition;
            }
            return true;
        }
    });
}
