activity 中：

    @Bind(R.id.expandableListView) ExpandableListView listView;
    private List<Bean> glist ;
    private Context context;
    @Override
    protected void onCreate(Bundle savedInstanceState) {

            List<ChildBean> clist = new ArrayList<>();
            clist.add(new ChildBean("","a"));

            glist.add(new Bean("a"+i,clist));
        }
        Log.d("aaa",glist.toString());
        listView.setAdapter(new Adapter());

    }


    class Adapter extends BaseExpandableListAdapter{


        @Override

        @Override

        @Override

            groupTv.setText(bean.getGroup());
            return view;
        }

        @Override

            TextView childTv = (TextView) view.findViewById(R.id.child_title);
            EditText editText = (EditText) view.findViewById(R.id.editText);
            List<ChildBean> clist = glist.get(i).getList();
            Bean bean  = glist.get(i);

            final ChildBean childbean = bean.getList().get(i1);
            childTv.setText(childbean.getTitle());

            editText.setText(childbean.getContent());

            editText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
                @Override
                public boolean onEditorAction(TextView textView, int i, KeyEvent keyEvent) {
                    Log.d("onEditorAction",textView.getText().toString());

                    childbean.setContent(textView.getText().toString());

            return view;
        }

        @Override
        public boolean isChildSelectable(int i, int i1) {
            return false;
        }

    }

group bean：

child Bean：

public class ChildBean {
    private String content; // 存放 EditText 输入的内容
    private String title ;

    public ChildBean(String content, String title) {
        this.content = content;
        this.title = title;
    }

    public String getContent() {
        return content;
    }

    public void setContent(String content) {
        this.content = content;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }
}
