使用了RecyclerView嵌套RecyclerView的方案。
购物车的第一个界面为RecyclerView，每个Item里面包含一个店铺。在Item中使用RecyclerView包含店铺和店铺的多个商品。
实现思路：
使用接口回调将第二个adapter的商品选择的监听事件回调给第一个adapter后再在第一个adapter中回调给MainActivity。
使用接口回调将第一个adapter的商品选择的监听事件回调给MainActivity。
在MainActivity中处理第一个adapter和第二个adapter的事件监听。
MainActivity：
public class MainActivity extends AppCompatActivity {
private RecyclerView recyclerView;
private CheckBox checkBox;
private recyclerAdapter adapter;
private RecyclerView.LayoutManager manager;
private List list;
private List cbeanList,cbeanListcp;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
recyclerView = (RecyclerView) findViewById(R.id.recyclerview);
checkBox = (CheckBox) findViewById(R.id.shop_checkbox);
list = new ArrayList<>();
//第一个店铺的数据
cbeanList = new ArrayList<>();
cbean c = new cbean();
c.setText("商品");
c.setIscheck(false);
cbean c1 = new cbean();
c1.setText("商品1");
c1.setIscheck(false);
cbeanList.add(c);
cbeanList.add(c1);
bean b = new bean();
b.setIscheck(false);
b.setText("店名");
b.setList(cbeanList);
//第二个店铺的数据
cbeanListcp = new ArrayList<>();
cbean c2 = new cbean();
c2.setText("商品2");
c2.setIscheck(false);
cbean c3 = new cbean();
c3.setText("商品3");
c3.setIscheck(false);
cbeanListcp.add(c2);
cbeanListcp.add(c3);
bean b1 = new bean();
b1.setIscheck(false);
b1.setText("店名1");
b1.setList(cbeanListcp);
//不能添加有重复变量的数据
list.add(b);
list.add(b1);
manager = new LinearLayoutManager(this);
recyclerView.setLayoutManager(manager);
//优化性能
recyclerView.setHasFixedSize(true);
adapter = new recyclerAdapter(list);
recyclerView.setAdapter(adapter);
//全选CheckBox监听
checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked){
for (int i = 0;i
第一个Adapter：
public class recyclerAdapter extends RecyclerView.Adapter{ private List list; public recyclerAdapter(List list){ this.list = list; } public static class MyHolder extends RecyclerView.ViewHolder{ private RecyclerView recyclerView; private TextView textView; private CheckBox checkBox; private recyclerAdapter1 adapter; private RecyclerView.LayoutManager manager; public CheckBox getCheckBox() { return checkBox; } public RecyclerView getRecyclerView() { return recyclerView; } public TextView getTextView() { return textView; } public MyHolder(View itemView) { super(itemView); recyclerView = (RecyclerView) itemView.findViewById(R.id.list_items); textView = (TextView) itemView.findViewById(R.id.tv_name); checkBox = (CheckBox) itemView.findViewById(R.id.checkbox0); manager = new LinearLayoutManager(itemView.getContext()); recyclerView.setLayoutManager(manager); } } @Override public MyHolder onCreateViewHolder(ViewGroup parent, int viewType) { View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.shop_item,null); MyHolder holder = new MyHolder(view); return holder; } @Override public void onBindViewHolder(final MyHolder holder, final int position) { holder.adapter = new recyclerAdapter1(list.get(position).getList()); holder.recyclerView.setAdapter(holder.adapter); holder.getTextView().setText(list.get(position).getText()); holder.getCheckBox().setChecked(list.get(position).ischeck()); holder.getCheckBox().setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { @Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { //将店铺的checkbox的点击变化事件进行回调 if (mCallBack!=null){ mCallBack.OnCheckListener(isChecked,position); } } }); //实现第二层RecyclerView的回调接口 holder.adapter.setCallBack(new recyclerAdapter1.allCheck() { @Override public void OnCheckListener(boolean isChecked, int childpostion) { //将店铺商品的checkbox的点击变化事件进行回调 if (mCallBack!=null){ mCallBack.OnItemCheckListener(isChecked,position,childpostion); } } }); holder.itemView.setTag(list.get(position)); } @Override public int getItemCount() { return list.size(); } private allCheck mCallBack; public void setCallBack(allCheck callBack) { mCallBack = callBack; } public interface allCheck{ //回调函数 将店铺的checkbox的点击变化事件进行回调 public void OnCheckListener(boolean isSelected,int position); //回调函数 将店铺商品的checkbox的点击变化事件进行回调 public void OnItemCheckListener(boolean isSelected,int parentposition,int chaildposition); } }
第二个Adapter:
public class recyclerAdapter1 extends RecyclerView.Adapter{ private List cbeanList, cbeanList1; public recyclerAdapter1(List cbeanList) { this.cbeanList = cbeanList; cbeanList1 = cbeanList; } public static class MyHolder extends RecyclerView.ViewHolder { private TextView textView; private CheckBox checkBox; public TextView getTextView() { return textView; } public CheckBox getCheckBox() { return checkBox; } public MyHolder(View itemView) { super(itemView); textView = (TextView) itemView.findViewById(R.id.checkbox_tv); checkBox = (CheckBox) itemView.findViewById(R.id.checkbox1); } } @Override public MyHolder onCreateViewHolder(ViewGroup parent, int viewType) { View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.check_item, null); MyHolder holder = new MyHolder(view); return holder; } @Override public void onBindViewHolder(final MyHolder holder, final int position) { holder.getTextView().setText(cbeanList.get(position).getText()); holder.getCheckBox().setChecked(cbeanList.get(position).ischeck()); holder.getCheckBox().setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { @Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { //将商品的checkbox的点击变化事件进行回调给第一个Recyclerview if (mCallBack != null) { mCallBack.OnCheckListener(isChecked, position); } } }); holder.itemView.setId(position); } @Override public int getItemCount() { return cbeanList.size(); } private allCheck mCallBack; public void setCallBack(allCheck callBack) { mCallBack = callBack; } public interface allCheck { //回调函数 将店铺商品的checkbox的点击变化事件进行回调 public void OnCheckListener(boolean isChecked, int childpostion); } }
实体类保存数据和选择状态：
public class bean {
private boolean ischeck;
private String text;
private List list;
public boolean ischeck() {
return ischeck;
}
public void setIscheck(boolean ischeck) {
this.ischeck = ischeck;
}
public String getText() {
return text;
}
public void setText(String text) {
this.text = text;
}
public List getList() {
return list;
}
public void setList(List list) {
this.list = list;
}
}
public class cbean {
private boolean ischeck;
private String text;
public boolean ischeck() {
return ischeck;
}
public void setIscheck(boolean ischeck) {
this.ischeck = ischeck;
}
public String getText() {
return text;
}
public void setText(String text) {
this.text = text;
}
}
布局文件：activity_main.xml
<&＃63;xml version="1.0" encoding="utf-8"&＃63;>
shop_item.xml:
<&＃63;xml version="1.0" encoding="utf-8"&＃63;>
check_item:
<&＃63;xml version="1.0" encoding="utf-8"&＃63;>
