❶ Android 仿餓了么加入購物車特效控制項
沒有兩個購物車哦~ 而且現在天氣炎熱 點一些熟食時要當心 怕得腸胃炎
❷ 關於android的購物車功能是怎麼實現的
主要代碼如下： 是主要代碼，
actvity中的代碼：
public class ShoppingCartActivity extends BaseActivity {
private List<Test> data;
private ListView mListView;
private ShoppingCartAdapter adapter;
private RelativeLayout rlRefresh;
private TextView tvRefresh;
private ProgressBar barRefresh;
private LinearLayout clear;
private CheckBox checkBox_select_all;
private CheckBox checkBox_add;
private TextView integral_sum;
private int sum = 0;
private int[] sumIntegral;
private Context context;
@
protected void onCreate(Bundle bundle) {
// TODO Auto-generated method stub
super.onCreate(bundle);
setContentView(R.layout.activity_shopping_cart);
initView();
}
private void initView() {
context = this;
showpage = 1;
isPermitFlag = true;
data = new ArrayList<Test>();
// 測試數據
data.add(new Test("id", "color", "type", "100"));
data.add(new Test("id", "color", "type", "200"));
data.add(new Test("id", "color", "type", "300"));
adapter = new ShoppingCartAdapter(context, handler, data);
sumIntegral = new int[data.size() + 1];
checkBox_add = (CheckBox) findViewById(R.id.checkbox_add);
integral_sum = (TextView) findViewById(R.id.integral_sum);
clear = (LinearLayout) findViewById(R.id.clear);
clear.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
data.clear();
adapter.notifyDataSetChanged();
integral_sum.setText(0 + "");
checkBox_select_all.setChecked(false);
checkBox_add.setClickable(false);
}
});
cted.entrySet().iterator();
for (int i = 0; i < data.size(); i++) {
int num = data.get(i).getNum();
int integral = Integer.valueOf(data.get(i).getIntegral());
nums.add(num);
});
<CheckBox
android:layout_width="12dp"
android:layout_height="12dp"
android:background="@drawable/clear" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:text="清空購物車"
android:textColor="#b61d1d"
android:textSize="@dimen/small_size" />
</LinearLayout>
</LinearLayout>
<CheckBox
android:id="@+id/checkbox_add"
style="@style/CustomCheckboxTheme2"
android:layout_width="wrap_content"
android:clickable="false"
android:layout_height="wrap_content" />
Adaper中的代碼：
public class ShoppingCartAdapter extends BaseAdapter {
private Context context;
private List<Test> loans;
private LayoutInflater inflater;
private static HashMap<Integer, Boolean> isSelected;
private static HashMap<Integer, Integer> numbers;
private Handler handler;
int num;// 商品數量
static class ViewHolder { // 自定義控制項集合
public CheckBox ck_select;
public ImageView pic_goods;
public TextView id_goods;
public TextView color_goods;
public TextView type_goods;
public TextView integral_goods;
public AddMinusWidget add_minus;
public LinearLayout layout;
public TextView number;
public Button minus;
public Button plus;
}
/**
* 實例化Adapter
*
* @param context
* @param data
*/
public ShoppingCartAdapter(Context context, Handler handler, List<Test> data) {
this.context = context;
this.inflater = LayoutInflater.from(context);
this.loans = data;
this.handler = handler;
isSelected = new HashMap<Integer, Boolean>();
numbers = new HashMap<Integer, Integer>();
initDate();
}
private void initDate() {
for (int i = 0; i < loans.size(); i++) {
getIsSelected().put(i, false);
getNumbers().put(i, 1);
}
}
@Override
public int getCount() {
return loans.size();
}
@Override
public Object getItem(int position) {
return loans.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
/**
* 計算選中商品的積分
*
* @return 返回需要付費的總積分
*/
private float getTotalPrice() {
Test bean = null;
float totalPrice = 0;
for (int i = 0; i < loans.size(); i++) {
bean = loans.get(i);
if (ShoppingCartAdapter.getIsSelected().get(i)) {
totalPrice += bean.getNum()
* Integer.valueOf(bean.getIntegral());
}
}
return totalPrice;
}
public static HashMap<Integer, Boolean> getIsSelected() {
return isSelected;
}
public static void setIsSelected(HashMap<Integer, Boolean> isSelected) {
ShoppingCartAdapter.isSelected = isSelected;
}
public static HashMap<Integer, Integer> getNumbers() {
return numbers;
}
public static void setNumbers(HashMap<Integer, Integer> numbers) {
ShoppingCartAdapter.numbers = numbers;
}
實體類
package com.autoserve.net33.model;
public class Test {
@Override
public String toString() {
return "test [id=" + id + ", color=" + color
+ ", type=" + type + ", integral=" + integral + "]";
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getColor() {
return color;
}
public void setColor(String color) {
this.color = color;
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public String getIntegral() {
return integral;
}
public void setIntegral(String integral) {
this.integral = integral;
}
private String id;
private String color;
private String type;
private String integral;
private int num;//商品數量
private int sumIntegral;
private boolean isChoosed; //商品是否在購物車中被選中
public Test(String id, String color, String type, String integral) {
super();
this.id = id;
this.color = color;
this.type = type;
this.integral = integral;
}
public Test() {
super();
}
public int getNum() {
return num;
}
public void setNum(int num) {
this.num = num;
}
public int getSumIntegral() {
return sumIntegral;
}
public void setSumIntegral(int sumIntegral) {
this.sumIntegral = sumIntegral;
}
public boolean isChoosed() {
return isChoosed;
}
public void setChoosed(boolean isChoosed) {
this.isChoosed = isChoosed;
}
}
❸ Android 實現美團，餓了么購物車效果
對兩個按鈕的背復景進行改變button、button2的選中制和為選擇狀態.beijing1).drawable.setBackgroundResource(R，讓後再button1和button2的點擊事件中，分別為button1的選中和為選擇狀態;上面是改變按鈕背景的代碼可以做兩組圖片
❹ android仿淘寶購物車 如何實現
這個問題可以使用代理解決，當你能理解代理業就可以搞定了。
具體代碼沒有，你可以去網上找代理代碼，特別類似蘋果代碼的那種代理。
❺ 如何實現購物車功能 android 博客
你先要把這個界面布局給弄好，圖片、文字、價格等都是從伺服器獲取的，然後用baseadapter適配器填充到listview中，最後進行相應的控制項的事件處理就好了。
❻ android 餓了么樣式彈出購物車動畫
看下代碼吧[java] view plain print?public float getT() { return t; } public void setT(float t) { Log.e("=====", t + " "); this.t = t;
❼ 添加購物車動畫效果android卡頓怎麼解決
優化動畫效果，在執行動畫的時候，防止其他控制項操作UI
❽ android仿餓了么加入購物車旋轉控制項動畫按鈕
這個二維控制項不支持，你可以對按鈕進行動畫式的先變窄再變寬，並進行顏色變換，從而達專到模屬擬立體翻轉的效果。更推薦的方法是直接使用WPF的3D功能，製作長方形，並在正反面都使用VisualBrush，而VisualBrush綁定到控制項，使得這個長方形看起來像一個立體的按鈕，並且擁有正反面，最後使用Transform3D派生的Rotetransform3D進行真正意義上的旋轉。
