关于ExpandableListView中的Adapter问题

我在ExpandableListview的二级菜单里面加了EditTest文本框，但是在调试时就出现了很奇怪的问题：但我点击子标签的文本框时键盘弹出来但是获取不了焦点，要再点一次文本框才能输入内容，而输入完后键盘一收起来刚输入的文本就没了，请问这个该怎么解决？

 private class MyExpendAdapter extends BaseExpandableListAdapter{

        /**
         * pic state
         */
        int []group_state=new int[]{R.drawable.group_right,R.drawable.group_down};//向左、向下小图标

        /**
         * group title
         */
        String []group_title=new String[]{"基本信息","商品详情","活动"};

        /**
         * child text
         */
        String [][] child_text=new String [][]{
                {"商品名称","商品价格","商品标签","商品特色","品牌"},
                {"商品颜色","重量","材料","尺码","产地"},
                {"张三","仇斌","温志豪","黎伦"}};

        /**
         * 获取一级标签中二级标签的内容
         */
        @Override
        public Object getChild(int groupPosition, int childPosition) {
            return child_text[groupPosition][childPosition];
        }

        /**

        @Override
        public long getChildId(int groupPosition, int childPosition) {
            return childPosition;
        }
        /**
         * 对一级标签下的二级标签进行设置
         */
        @SuppressLint("SimpleDateFormat")
        @Override
        public View getChildView(int groupPosition, int childPosition,
                                 boolean isLastChild, View convertView, ViewGroup parent) {
            convertView=getLayoutInflater().inflate(R.layout.child, null);
            TextView tv=(TextView) convertView.findViewById(R.id.tv);
            //TextView time=(TextView) convertView.findViewById(R.id.time);
            EditText ed1 =(EditText)convertView.findViewById(R.id.edit_1);
            tv.setText(child_text[groupPosition][childPosition]);
            ed1.setText(child_text[groupPosition][childPosition]);
            //获取系统事件
           // long times=System.currentTimeMillis();
            //SimpleDateFormat format=new SimpleDateFormat("yyyy年mm月dd日hh时mm分ss秒");
            //String date=format.format(times);
            //time.setText(date);
            ed1.setText(ed1.getText());

            return convertView;
        }

        /**

            }else{
                iv.setImageResource(R.drawable.group_down);
            }

            return convertView;
        }
        /**

            return true;
        }
