[英]How to make section in recycle view?
I spend much time in searching about recycle multi type view . 我花了很多时间来搜索回收多类型视图。 I already use navigation drawer using recycle view there i use two view one for header and one for menu item.
我已经在使用回收视图的导航抽屉了,在这里我使用了两个视图,一个用于标题,一个用于菜单项。 Now i need to inflate two array list like first one for 'feature' item and another for 'normal' list of item in recycle view .In this case i need to make two section in recycle view first one for 'feature' item after finish feature item , need to make another section for normal item.
现在我需要在回收视图中添加两个数组列表,例如第一个用于“功能”项目,另一个用于“正常”项目列表。在这种情况下,我需要在回收视图中创建两个部分,第一个用于完成后的“功能”项目特色商品,需要为普通商品另辟一个部分。 How can i get this ?
我怎么能得到这个? any idea ?
任何想法 ?
You can use the library SectionedRecyclerViewAdapter to group your data into sections. 您可以使用SectionedRecyclerViewAdapter库将数据分组。
First create a Section class: 首先创建一个Section类:
class MySection extends StatelessSection {
String title;
List<String> list;
public MySection(String title, List<String> list) {
// call constructor with layout resources for this Section header, footer and items
super(R.layout.section_header, R.layout.section_item);
this.title = title;
this.list = list;
}
@Override
public int getContentItemsTotal() {
return list.size(); // number of items of this section
}
@Override
public RecyclerView.ViewHolder getItemViewHolder(View view) {
// return a custom instance of ViewHolder for the items of this section
return new MyItemViewHolder(view);
}
@Override
public void onBindItemViewHolder(RecyclerView.ViewHolder holder, int position) {
MyItemViewHolder itemHolder = (MyItemViewHolder) holder;
// bind your view here
itemHolder.tvItem.setText(list.get(position));
}
@Override
public RecyclerView.ViewHolder getHeaderViewHolder(View view) {
return new SimpleHeaderViewHolder(view);
}
@Override
public void onBindHeaderViewHolder(RecyclerView.ViewHolder holder) {
MyHeaderViewHolder headerHolder = (MyHeaderViewHolder) holder;
// bind your header view here
headerHolder.tvItem.setText(title);
}
}
Then you set up the RecyclerView with your Sections: 然后,使用您的Sections设置RecyclerView:
// Create an instance of SectionedRecyclerViewAdapter
SectionedRecyclerViewAdapter sectionAdapter = new SectionedRecyclerViewAdapter();
// Create your sections with the list of data for each year
MySection section1 = new MySection("Feature", firstDataList);
MySection section2 = new MySection("Normal", secondDataList);
// Add your Sections to the adapter
sectionAdapter.addSection(section1);
sectionAdapter.addSection(section2);
// Set up your RecyclerView with the SectionedRecyclerViewAdapter
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recyclerview);
recyclerView.setLayoutManager(new LinearLayoutManager(getContext()));
recyclerView.setAdapter(sectionAdapter);
