   android:scrollbars="vertical"
   android:fadingEdge="vertical"
   android:cacheColorHint="#00000000">
 </ListView>

我的java文件

My .java file

public class TestListView extends Activity{

       private DatabaseConection db;
       Button btn;         
       private List<Customer> custList = new ArrayList<Customer>();
       private CustomListenerAdapter custListAdaptor;    
       private ListView list;

       /**
        * Called when the activity is first created.
       */
       @Override
       public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);  
            setContentView(R.layout.test_listview);
            // Connection object for Login 
            db= new DatabaseConection(this);

            btn = (Button)findViewById(R.id.button1);
            btn.setOnClickListener(new OnClickListener() {                      
                @SuppressWarnings("deprecation")
                public void onClick(View v) {   
                    createListViewDialog(btn);

                } 
            });

            try{
                list = (ListView) findViewById(R.id.listView1);                
                // populate the store list
                custList = db.getAllCustomers();                   
                // create an adaptor with the store list
                custListAdaptor = new CustomListenerAdapter(this,custList);                
                // assign the listview an adaptor
                 list.setAdapter(custListAdaptor);                

            }catch(Exception e){
               e.getStackTrace();
            }

        }



           // on button click i called dialog wich contains List (sorted)
        public void createListViewDialog(final Button btnId) {      
            AlertDialog levelDialog = null;     
            // Creating and Building the Dialog 
            AlertDialog.Builder builder = new AlertDialog.Builder(this); 

            final ArrayAdapter<Customer> ad = new ArrayAdapter<Customer>          (this,android.R.layout.simple_list_item_1,custList.toArray(new Customer[custList.size()]));

            builder.setSingleChoiceItems(ad, -1, new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int item) {                 
                    btnId.setText(ad.getItem(item).toString());         
                }
            });

             levelDialog = builder.create();
             levelDialog.show();      
        }
}

在上面的code我已经使用警告对话框，显示客户名单
但我也想打电话给CustomListenerAdapter在同一
DialogBox的显示的字母索引快速滚动我可以叫2适配器类
在CUSTLIST结果
如果没有的话，请给我其他选项来显示字母索引
对于列表对话框中显示视图（弹出）

In the above code i have used Alert Dialog which shows List of customers but i also want to call CustomListenerAdapter in same dialogbox to show alphabetical indexer for fast scroll can i call 2 adapter classes on "CustList"
if not then please give me other options to show alphabetical indexer for list view shown in dialog box (popup)

（在这里你可以看到它 https://github.com/andraskindler/quickscroll 想法。 ..
要为列表视图对话框工作）

推荐答案

是的，你可以使用多个适配​​器的ListView如果

Yes you can use Multiple Adapter for ListView if,

• 如果你不与在同一时间两个适配器填充您的ListView控件。


• 如果您交替使用适配器填充您的ListView控件那么它的罚款。


• 如果一个适配器没有影响其他的只有一个适配器将生效的时间。

我觉得你的情况，你都显示在同一活动的ListView都因此其最好使用一个单独的适配器

I think in your case you are showing both ListView at the same Activity so its better to use a seperate Adapter
