首先先将自定义控件加减的布局代码奉上
plus_layout.xml
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent"> <Button android:id="@+id/revserse" android:layout_width="10dp" android:layout_height="wrap_content" android:background="#00FFFFFF" android:text="-" /> <EditText android:id="@+id/content" android:layout_width="wrap_content" android:layout_height="wrap_content" android:inputType="number" android:text="1" /> <Button android:id="@+id/add" android:layout_width="10dp" android:layout_height="wrap_content" android:background="#00FFFFFF" android:text="+" /> </LinearLayout>
adapter_layout.xml的布局
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@color/cwhite" android:orientation="vertical"> <LinearLayout android:id="@+id/ll_shopCart_header" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical"> <View android:id="@+id/view" android:layout_width="match_parent" android:layout_height="@dimen/margin_10dp" android:background="@color/background_color"> </View> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:gravity="center_vertical"> <!-- 商店checkbox --> <CheckBox android:id="@+id/shop_checkBox" android:layout_width="wrap_content" android:layout_height="wrap_content" android:paddingBottom="@dimen/margin_10dp" android:paddingLeft="@dimen/margin_15dp" android:paddingRight="@dimen/margin_15dp" android:paddingTop="@dimen/margin_10dp" android:src="@drawable/shopcart_selected" /> <!-- 商店明晨 --> <TextView android:id="@+id/tv_item_shopcart_shopname" android:layout_width="match_parent" android:layout_height="wrap_content" android:drawableLeft="@drawable/shopcart_shop" android:drawablePadding="@dimen/padding_5dp" android:padding="@dimen/padding_10dp" android:text="宝儿家服装" android:textColor="@color/cblack" /> </LinearLayout> </LinearLayout> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:gravity="center_vertical"> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical"> <View android:layout_width="match_parent" android:layout_height="@dimen/margin_1dp" android:background="@color/background_color" /> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:gravity="center_vertical" android:orientation="horizontal"> <!-- 商品 checkbox --> <CheckBox android:id="@+id/item_checkbox" android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="@dimen/margin_15dp" android:src="@drawable/shopcart_selected" /> <!-- 商品图片 --> <ImageView android:id="@+id/item_pic" android:layout_width="60dp" android:layout_height="60dp" android:layout_margin="@dimen/margin_10dp" /> <LinearLayout android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" android:orientation="vertical"> <TextView android:id="@+id/item_price" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="¥185" android:textColor="@color/main_red_text" android:textSize="@dimen/common_font_size_14" /> <LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginBottom="@dimen/margin_5dp" android:layout_marginTop="@dimen/margin_5dp"> <TextView android:id="@+id/item_name" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="颜色：黑色" android:textColor="@color/cblack" android:textSize="@dimen/common_font_size_12" /> <TextView android:id="@+id/tv_item_shopcart_cloth_size" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="@dimen/margin_10dp" android:text="尺寸：XL" android:textColor="@color/cblack" android:textSize="@dimen/common_font_size_12" /> </LinearLayout> <com.qizu.yuekaocar.PlusView android:id="@+id/plus_view_id" android:layout_width="100dp" android:layout_height="wrap_content"> </com.qizu.yuekaocar.PlusView> </LinearLayout> <View android:layout_width="@dimen/margin_1dp" android:layout_height="match_parent" android:layout_marginBottom="@dimen/padding_10dp" android:layout_marginTop="@dimen/padding_10dp" android:background="@color/splitline_color" /> <ImageView android:id="@+id/item_del" android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="@dimen/margin_20dp" android:src="@drawable/shopcart_delete" /> </LinearLayout> </LinearLayout> </LinearLayout> <View android:layout_width="match_parent" android:layout_height="@dimen/margin_1dp" android:background="@color/background_color" /> </LinearLayout>
activity_main.xml的布局
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" tools:context="com.qizu.yuekaocar.MainActivity"> <android.support.v7.widget.RecyclerView android:id="@+id/third_recyclerView" android:layout_width="match_parent" android:layout_height="0dp" android:layout_weight="1"> </android.support.v7.widget.RecyclerView> <LinearLayout android:id="@+id/third_pay_linear" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_weight="0" android:background="#FFFFFF" android:gravity="center_vertical" android:orientation="horizontal"> <CheckBox android:id="@+id/third_allSelect" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="@dimen/margin_10dp" android:drawableLeft="@drawable/shopcart_selected" android:drawablePadding="@dimen/padding_5dp" android:text="全选" /> <LinearLayout android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" android:orientation="vertical"> <TextView android:id="@+id/third_totalPrice" android:layout_width="200dp" android:layout_height="wrap_content" android:paddingLeft="@dimen/padding_10dp" android:paddingTop="@dimen/padding_10dp" android:text="总价：" android:textColor="@color/cblack" android:textSize="@dimen/common_font_size_16" /> <TextView android:id="@+id/third_totalNum" android:layout_width="wrap_content" android:layout_height="wrap_content" android:paddingBottom="@dimen/padding_10dp" android:paddingLeft="@dimen/padding_10dp" android:text="共0件商品" android:textColor="@color/cblack" android:textSize="@dimen/common_font_size_14" /> </LinearLayout> <TextView android:id="@+id/third_submit" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginRight="@dimen/margin_10dp" android:background="@drawable/login_btn" android:paddingBottom="@dimen/padding_10dp" android:paddingLeft="@dimen/margin_30dp" android:paddingRight="@dimen/margin_30dp" android:paddingTop="@dimen/padding_10dp" android:text="去结算" android:textColor="#000000" /> </LinearLayout> </LinearLayout>
然后是自定义控件PlusView
public class PlusView extends LinearLayout { private Button revserse; private Button add; private EditText editText; private int mCount = 1; public PlusView(Context context) { super(context); } public PlusView(Context context, @Nullable AttributeSet attrs) { super(context, attrs); View view = LayoutInflater.from(context).inflate(R.layout.plus_layout, null, false); revserse = view.findViewById(R.id.revserse); add = view.findViewById(R.id.add); editText = view.findViewById(R.id.content); revserse.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { try { String content = editText.getText().toString().trim(); int count = Integer.valueOf(content); if(count > 1){ mCount = count-1; editText.setText(mCount+ ""); if(listener != null){ listener.click(mCount); } } } catch (NumberFormatException e) { e.printStackTrace(); } } }); add.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { try { String content = editText.getText().toString().trim(); int count = Integer.valueOf(content); mCount = count+1; editText.setText(mCount+ ""); if(listener !=null){ listener.click(mCount); } } catch (NumberFormatException e) { e.printStackTrace(); } } }); editText.addTextChangedListener(new TextWatcher() { @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { } @Override public void onTextChanged(CharSequence s, int start, int before, int count) { } @Override public void afterTextChanged(Editable s) { } }); addView(view); } public PlusView(Context context, @Nullable AttributeSet attrs, int defStyleAttr) { super(context, attrs, defStyleAttr); } public void setEditText(int num){ if(editText != null){ editText.setText(num+ ""); } } public ClickListener listener; public void setListener(ClickListener listener){ this.listener = listener; } public interface ClickListener{ public void click(int count); } }然后是ShopAdapter
public class ShopAdapter extends RecyclerView.Adapter<ShopAdapter.MyViewHolder> { private Context context; private List<ShopBean.DataBean.ListBean> list; private Map<String, String> map = new HashMap<>(); public ShopAdapter(Context context) { this.context = context; } public void add(ShopBean bean) { if (this.list == null) { this.list = new ArrayList<>(); } for (ShopBean.DataBean shop : bean.getData()) { map.put(shop.getSellerid(), shop.getSellerName()); for (int i = 0; i < shop.getList().size(); i++) { this.list.add(shop.getList().get(i)); } } setFirst(this.list); notifyDataSetChanged(); } private void setFirst(List<ShopBean.DataBean.ListBean> list) { if (list.size() > 0) { list.get(0).setIsFirst(1); for (int i = 1; i < list.size(); i++) { if (list.get(i).getSelected() == list.get(i - 1).getSellerid()) { list.get(i).setIsFirst(2); } else { list.get(i).setIsFirst(1); } } } } @Override public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { View view = View.inflate(context, R.layout.adapter_layout, null); return new MyViewHolder(view); } @Override public void onBindViewHolder(final MyViewHolder holder, final int position) { if (list.get(position).getIsFirst() == 1) { holder.shopCheckBox.setVisibility(View.VISIBLE); holder.tvItemShopcartShopname.setVisibility(View.VISIBLE); holder.shopCheckBox.setChecked(list.get(position).isShopSelected()); // list.get(position).getSellerid(); holder.tvItemShopcartShopname.setText(map.get(String.valueOf(list.get(position).getSellerid()))); }else{ holder.shopCheckBox.setVisibility(View.GONE); holder.tvItemShopcartShopname.setVisibility(View.GONE); } holder.itemCheckbox.setChecked(list.get(position).isItemSelected()); String[] url = list.get(position).getImages().split("\\|"); ImageLoader.getInstance().displayImage(url[0],holder.itemPic); holder.itemName.setText(list.get(position).getTitle()); holder.itemPrice.setText(list.get(position).getPrice()+""); holder.plusViewId.setEditText(list.get(position).getNum()); holder.shopCheckBox.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { list.get(position).setShopSelected(holder.shopCheckBox.isChecked()); for(int i = 0;i < list.size(); i++){ if(list.get(position).getSellerid() ==list.get(i).getSellerid()){ list.get(i).setItemSelected(holder.shopCheckBox.isChecked()); } } notifyDataSetChanged(); sum(list); } }); holder.itemCheckbox.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { list.get(position).setItemSelected(holder.itemCheckbox.isChecked()); for(int i = 0;i<list.size(); i++){ for(int j =0; j<list.size(); j++){ if(list.get(i).getSellerid()== list.get(j).getSellerid() && !list.get(j).isItemSelected()){ list.get(i).setShopSelected(false); break; }else{ list.get(i).setShopSelected(true); } } } notifyDataSetChanged(); sum(list); } }); holder.itemDel.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { list.remove(position); setFirst(list); notifyDataSetChanged(); sum(list); } }); holder.plusViewId.setListener(new PlusView.ClickListener() { @Override public void click(int count) { list.get(position).setNum(count); notifyDataSetChanged(); sum(list); } }); } @Override public int getItemCount() { return list == null ? 0 : list.size(); } private void sum(List<ShopBean.DataBean.ListBean> list){ int totalNum = 0 ; float totalMoney = 0.0f; boolean allCheck =true; for(int i=0;i<list.size();i++){ if(list.get(i).isItemSelected()){ totalNum += list.get(i).getNum() ; totalMoney += list.get(i).getNum() * list.get(i).getPrice(); }else { allCheck = false; } } listener.setTotal(totalMoney+"",totalNum+"",allCheck); } public void selectAll(boolean check){ for(int i=0;i<list.size();i++){ list.get(i).setShopSelected(check); list.get(i).setItemSelected(check); } notifyDataSetChanged(); sum(list); } public class MyViewHolder extends RecyclerView.ViewHolder { @BindView(R.id.view) View view; @BindView(R.id.shop_checkBox) CheckBox shopCheckBox; @BindView(R.id.tv_item_shopcart_shopname) TextView tvItemShopcartShopname; @BindView(R.id.ll_shopCart_header) LinearLayout llShopCartHeader; @BindView(R.id.item_checkbox) CheckBox itemCheckbox; @BindView(R.id.item_pic) ImageView itemPic; @BindView(R.id.item_price) TextView itemPrice; @BindView(R.id.item_name) TextView itemName; @BindView(R.id.tv_item_shopcart_cloth_size) TextView tvItemShopcartClothSize; @BindView(R.id.plus_view_id) PlusView plusViewId; @BindView(R.id.item_del) ImageView itemDel; public MyViewHolder(View itemView) { super(itemView); ButterKnife.bind(this, itemView); } } public UpdateUiListener listener; public void setListener(UpdateUiListener listener){ this.listener = listener; } interface UpdateUiListener { public void setTotal(String total,String num,boolean allCheck); } }VIew层
