您可以使用下面的代碼

//列表視圖上的孩子點擊收聽

expListView.setOnChildClickListener(new OnChildClickListener() { 

    @Override 
    public boolean onChildClick(ExpandableListView parent, View v, 
      int groupPosition, int childPosition, long id) { 
     //You have to create next activity say NextActivity.java 
     Intent intent = new Intent(getActivity(), NextActivity.class); 
     startActivity(intent); 
     return false; 
    } 
});
