自定义Spinner下拉列表

说道android下拉框spineer，框架中虽有现成的控件，但实际效果可能并不是我们所需要的那种，如下图：

其实我们更需要的是像WEB那种风格，如图所示：

其实实现也很简单，就是自定义个popwindow就可以了

下面贴上代码片段：

**\[java\]**  view plain copy print ?

1.  **public** **class** SpinerPopWindow **extends** PopupWindow **implements** OnItemClickListener\{  
2.    
3.      **private** Context mContext;  
4.      **private** ListView mListView;  
5.      **private** NormalSpinerAdapter mAdapter;  
6.      **private** IOnItemSelectListener mItemSelectListener;  
7.        
8.        
9.      **public** SpinerPopWindow(Context context)  
10.     \{  
11.         **super**(context);

14.         init();  
15.     \}  
16.       
17.       
18.     **public** **void** setItemListener(IOnItemSelectListener listener)\{  
19.         mItemSelectListener = listener;  
20.     \}  
21.   
22.       
23.     **private** **void** init()  
24.     \{  
25.         View view = LayoutInflater.from(mContext).inflate(R.layout.spiner\_window\_layout, **null**);  
26.         setContentView(view);         
27.         setWidth(LayoutParams.WRAP\_CONTENT);  
28.         setHeight(LayoutParams.WRAP\_CONTENT);  
29.           
30.         setFocusable(**true**);

32.         setBackgroundDrawable(dw);  
33.       
34.

36.           
37.   
38.         mAdapter = **new** NormalSpinerAdapter(mContext);     
39.         mListView.setAdapter(mAdapter);   
40.         mListView.setOnItemClickListener(**this**);  
41.     \}  
42.       
43.       
44.     **public** **void** refreshData(List<String> list, **int** selIndex)  
45.     \{  
46.         **if** (list != **null** && selIndex  != -1)  
47.         \{  
48.             mAdapter.refreshData(list, selIndex);  
49.         \}  
50.     \}  
51.   
52.   
53.     @Override  
54.     **public** **void** onItemClick(AdapterView<?> arg0, View view, **int** pos, **long** arg3) \{  
55.         dismiss();  
56.         **if** (mItemSelectListener != **null**)\{  
57.             mItemSelectListener.onItemClick(pos);  
58.         \}  
59.     \}  
60.   
61.   
62.       
63. \}

public class SpinerPopWindow extends PopupWindow implements OnItemClickListener{
    
    	private Context mContext;

    			mItemSelectListener.onItemClick(pos);

就这么简单，具体UI美化大家再修改下xml就可以了

自定义一个类重写toString方法（CustemObject），自定义一个继承自AbstractSpinerAdapter的类确定对象类型（CustemSpinerAdapter）

构造具体的AbstractSpinerAdapter类对象（CustemSpinerAdapter）

通过refreshData填充数据，然后调用SpinerPopWindow的setAdatper设置数据源，OK大功告成！
