Android 購物選擇顏色(尺碼)實現(xiàn)(一)這篇文章只是簡單的介紹以及實現(xiàn)了點擊效果還沒有實現(xiàn)顏色、尺碼、庫存等聯(lián)動所以在閑暇時間就寫了這篇文章實現(xiàn)這樣的效果。首先還是上幾張?zhí)詫毜男Ч麍D在選擇尺碼或者顏色分類的時候顏色分類、尺碼、庫存以及圖片都會有相應變化。接下來我們 就看看如何實現(xiàn)這樣的效果。先看看我實現(xiàn)的效果圖一.分析要實現(xiàn)這樣的效果商品屬性就得有尺碼、顏色、庫存等我們簡稱為sku當你選擇某一個尺碼的時候先查找該顏色對應的尺碼列表是什么接著用這個尺碼列表和總的尺碼列表進行對比要是有尺碼不在總尺碼列表中那么就標記改尺碼是不可選的顏色也同理。只要你明白這道理那么就很好理解了。下來我們看看具體的代碼實現(xiàn)。二.實現(xiàn)1.新建項目2.打開布局文件activity_main.xml該布局文件是主界面布局代碼就不羅列了具體代碼見代碼下載。3.在layou文件夾中新建布局gridview_item.xml文件該布局文件主要是設置GridView的item布局主要是一個TextView顯示商品屬性PS: 這一塊要是不了解的話可以先看看這篇文章Android 購物選擇顏色(尺碼)實現(xiàn)(一)4.新建MyGridView類繼承GridView解決滑動沖突/** * 滑動沖突 */ public class MyGridView extends GridView { public MyGridView(Context context) { super(context); } public MyGridView(Context context, AttributeSet attrs) { super(context, attrs); } public MyGridView(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } Override public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { int expandSpec MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE 2, MeasureSpec.AT_MOST); super.onMeasure(widthMeasureSpec, expandSpec); } Override public boolean dispatchTouchEvent(MotionEvent ev) { if (ev.getAction() MotionEvent.ACTION_MOVE) { return true; } return super.dispatchTouchEvent(ev); } }5.新建SkuAdapter 繼承BaseAdapter其中用到的接口回調public class SkuAdapter extends BaseAdapter { private ListBean list;//數(shù)據(jù)源 private LayoutInflater mInflater;// 得到一個LayoutInfalter對象用來導入布局 public onItemClickListener itemClickListener;// 接口回調 public void setItemClickListener(onItemClickListener itemClickListener) { this.itemClickListener itemClickListener; } public SkuAdapter(ListBean list, Context context) { super(); this.mInflater LayoutInflater.from(context); this.list list; } Override public int getCount() { // TODO Auto-generated method stub return list.size(); } Override public Object getItem(int position) { // TODO Auto-generated method stub return list.get(position); } Override public long getItemId(int position) { // TODO Auto-generated method stub return position; } Override public View getView(final int position, View convertView, ViewGroup parent) { // TODO Auto-generated method stub ViewHolder holder; if (convertView null) { holder new ViewHolder(); convertView mInflater.inflate(R.layout.gridview_item, null); /** 得到各個控件的對象 */ holder.title (TextView) convertView.findViewById(R.id.ItemText); holder.layout (LinearLayout) convertView.findViewById(R.id.layout); convertView.setTag(holder);// 綁定ViewHolder對象 } else { holder (ViewHolder) convertView.getTag();// 取出ViewHolder對象 } final Bean bean list.get(position); switch (bean.getStates()) { // 選中 case 0: holder.layout.setBackgroundResource(R.xml.shape2); holder.title.setTextColor(Color.WHITE); break; // 未選中 case 1: holder.layout.setBackgroundResource(R.xml.shape1); holder.title.setTextColor(Color.BLACK); break; // 不可選 case 2: holder.layout.setBackgroundResource(R.xml.shape1); holder.title.setTextColor(Color.parseColor(#999999)); break; default: break; } /** 設置TextView顯示的內容即我們存放在動態(tài)數(shù)組中的數(shù)據(jù) */ holder.title.setText(bean.getName()); holder.layout.setOnClickListener(new OnClickListener() { Override public void onClick(View v) { // TODO Auto-generated method stub if (itemClickListener ! null) { if(!bean.getStates().equals(2)){ itemClickListener.onItemClick(bean, position); } } } }); return convertView; } public final class ViewHolder { public TextView title; public LinearLayout layout; } public interface onItemClickListener { public void onItemClick(Bean bean, int position); } }6.新建Constants 類當然你也可以自己在Activity中定義常量public class Constants { //顏色數(shù)組 public static final String[] colorArr{鐵藍灰,孔雀藍,深藍,中國紅,艷紫}; //尺碼數(shù)組 public static final String[] sizeArr{S,M,L,XL,XXL,XXXL}; }7.新建DataUtil用來數(shù)據(jù)處理代碼太長就不講解了具體的代碼請下載代碼后查看8.最主要的類MainActivity該類包含了所有的實現(xiàn)代碼如下public class MainActivity extends Activity { ListSkuItme mList;// sku數(shù)據(jù) ListBean mColorList;// 顏色列表 ListBean mSizeList;// 尺碼列表 GridView gvColor;// 顏色 GridView gvSize;// 尺碼 SkuAdapter skuColorAdapter;// 顏色適配器 SkuAdapter skuSizeAdapter;// 尺碼適配器 String color;// String size;// TextView tvSkuName;// 顯示sku TextView tvSkuStock;// 顯示庫存 int stock 0;// 庫存 Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); gvSize (GridView) findViewById(R.id.gv_size); gvColor (GridView) findViewById(R.id.gv_color); tvSkuName (TextView) findViewById(R.id.tv_sku); tvSkuStock (TextView) findViewById(R.id.tv_sku_stock); addData(); stock DataUtil.getAllStock(mList); if (stock 0) { tvSkuStock.setText(庫存 stock ); } skuColorAdapter new SkuAdapter(mColorList, this); gvColor.setAdapter(skuColorAdapter); skuColorAdapter.setItemClickListener(new onItemClickListener() { Override public void onItemClick(Bean bean, int position) { // TODO Auto-generated method stub color bean.getName(); switch (bean.getStates()) { case 0: // 清空尺碼 mSizeListDataUtil.clearAdapterStates(mSizeList); skuSizeAdapter.notifyDataSetChanged(); // 清空顏色 mColorListDataUtil.clearAdapterStates(mColorList); skuColorAdapter.notifyDataSetChanged(); color ; // 判斷使用選中了尺碼 if (!TextUtils.isEmpty(size)) { // 選中尺碼計算庫存 stock DataUtil.getSizeAllStock(mList,size); if (stock 0) { tvSkuStock.setText(庫存 stock ); } tvSkuName.setText(請選擇尺碼); // 獲取該尺碼對應的顏色列表 ListString list DataUtil.getColorListBySize(mList,size); if (list !
