尝试android.widget.AdapterView.OnItemClickListener。

   expListView.setOnItemClickListener(new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view,
                int position, long arg3) {
            StartIntent();
        }
    });

请看这里的开发者文档

---

   mExpandableList.setOnChildClickListener(new OnChildClickListener() {
       @Override
       public boolean onChildClick(ExpandableListView parent, View v,int groupPosition, int childPosition, long id) {
          /*Additional info: You can use the view variable(v) here to get the params from the view you are clicking just in case you want to pass any data of that view to new activity(use casting to casting point to a particular view type). then pass that data as extra along with intent */
          Intent intent=new Intent(CurrentClass.this,NewActivity.class)
          startActivity(intent);     
          return true;
        }
    });

注意:不要忘记在manifest

您只需要修改getChildView方法，像这样添加OnClickListener:

     @Override
         public View getChildView(final int groupPosition, final int childPosition,
         boolean isLastChild, View convertView, ViewGroup parent) {
         final String childText = (String) getChild(groupPosition, childPosition);
         if (convertView == null) {
         LayoutInflater infalInflater = (LayoutInflater) this._context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
         convertView = infalInflater.inflate(R.layout.list_item, null);
         }
         TextView txtListChild = (TextView) convertView.findViewById(R.id.lblListItem);     
         txtListChild.setText(childText);
         //-----------------------------------------------------------------------------------
         txtListChild.setOnClickListener(new View.OnClickListener() {    
             @Override
             public void onClick(View view) {
//put your groupPosition and childPosition to the intent and start the activity
                 startActivity(YOUR INTENT);
             }    
         }//-----------------------------------------------------------------------------------

         return convertView;
         }

或者，您可以为children layout:

设置tonclicklistener

convertView.setOnClickListener(...)
