贴个自定义dialog中显示ExpandableListView 的代码

	transplanttypeButton.setOnClickListener(new OnClickListener() {
				
				@Override
				public void onClick(View v) {
					// TODO Auto-generated method stub
				LayoutInflater layoutInflater  = TransplantActivity.this.getLayoutInflater();
				final AlertDialog dialog = new AlertDialog.Builder(TransplantActivity.this).create();
				dialog.show();
				 Window window = dialog.getWindow();
				        // *** 主要就是在这里实现这种效果的.
				        // 设置窗口的内容页面,shrew_exit_dialog.xml文件中定义view内容
				 window.setContentView(R.layout.transplanttypedialog);
				 ExpandableListView  expandablelistview  =  (ExpandableListView) window.findViewById(R.id.expandableListView1);
				 
				 
				 final ArrayList<String> groupArray = new  ArrayList<String>();   
				 final ArrayList<List<String>> childArray = new  ArrayList<List<String>>();
				
				groupArray.add("地膜");
				groupArray.add("非地膜");
				
				final ArrayList<String> temparray = new  ArrayList<String>(); 
				temparray.add("地膜井窖");
				temparray.add("地膜非井窖");        
 
				final ArrayList<String> temparray1 = new  ArrayList<String>();     
				temparray1.add("井窖"); 
				temparray1.add(" 非井窖"); 
                      
				childArray.add(temparray);
				childArray.add(temparray1);
				expandablelistview.setAdapter(new  ExpandableAdapter(TransplantActivity.this,groupArray,childArray ));
				expandablelistview.setOnChildClickListener(new OnChildClickListener() {
					
					@Override
					public boolean onChildClick(ExpandableListView parent, View v,
							int groupPosition, int childPosition, long id) {
						
						if (groupPosition==0) {
							typestring = temparray.get(childPosition);
						}
						if (groupPosition==1) {
							typestring = temparray1.get(childPosition);
						}
						dialog.dismiss();
						transplanttypeButton.setText(typestring);
						return true;
					}
				});
				}
