效果就是这样，我们要实现这样的效果，其实思路就是：

1、我们要记录下按钮的状态，同时保存文本框。

2、主要是在BaseAdapter中进行监听。

class MyAdapter extends BaseAdapter{
    		private Map<Integer,Integer> mapToggle;		//用于存储Toggle的状态
    		private Map<Integer,String> mapReason;		//用于存储文本框的内容
    		public MyAdapter(){
    			mapToggle = new HashMap<Integer,Integer>();
    			mapReason = new HashMap<Integer,String>();
    		}
    		@Override
    		public int getCount() {
    			return 30;
    		}
    
    		@Override
    		public Object getItem(int position) {
    			return null;
    		}
    
    		@Override
    		public long getItemId(int position) {
    			return position;
    		}
    
    		@Override
    		public View getView(int position, View convertView, ViewGroup parent) {
    				convertView = LayoutInflater.from(_this).inflate(R.layout.activity_price_item, null);
    				TextView tv_title = (TextView) convertView.findViewById(R.id.price_item_title);
    				TextView tv_price = (TextView) convertView.findViewById(R.id.price_item_price);
    				final EditText et_text = (EditText) convertView.findViewById(R.id.price_item_reason);
    				ToggleButton toggleButton = (ToggleButton) convertView.findViewById(R.id.price_item_toggle);
    				final LinearLayout linear= (LinearLayout) convertView.findViewById(R.id.price_relative);
    				tv_title.setText("测试用例" + position);
    				linear.setTag(position);
    				et_text.addTextChangedListener(new TextWatcher() {
    				
    				@Override
    				public void onTextChanged(CharSequence s, int start, int before, int count) {
    					// TODO Auto-generated method stub
    					
    				}
    				
    				@Override
    				public void beforeTextChanged(CharSequence s, int start, int count,
    						int after) {
    					
    				}
    				
    				@Override
    				public void afterTextChanged(Editable s) {//记录文本框的内容
    					int index = (Integer) linear.getTag();
    					mapReason.put(index, s.toString());
    				}
    			});
    		toggleButton.setOnCheckedChangeListener(new OnCheckedChangeListener(){
    	            @Override
    	            public void onCheckedChanged(CompoundButton buttonView,
    	                    boolean isChecked) {
    	                if(isChecked){
    	                	int index = (Integer) linear.getTag();
    	                	mapToggle.put(index, 0);
    	                    linear.setVisibility(View.GONE);
    	                }else{
    	                	int index = (Integer) linear.getTag();
    	                	mapToggle.put(index, 1);
    	                    linear.setVisibility(View.VISIBLE);
    	                }
    	            }
    	        });
    			if(mapToggle != null){//重新恢复状态
    				int index = (Integer) linear.getTag();
    				if(!mapToggle.keySet().isEmpty() && mapToggle.containsKey(index) && mapToggle.get(index) == 1){
    					if(toggleButton.isChecked())
    					toggleButton.setChecked(false);
    				}else{
    					toggleButton.setChecked(true);
    				}
    				if(!mapReason.keySet().isEmpty())
    				et_text.setText(mapReason.get(index));
    			}
    			return convertView;
    		}
    	}
