    </LinearLayout>

</LinearLayout>


这对我来说也很有效。。。布局中的所有项(子项)必须设置为focusable=“false”和clickable=“false”。但是,如果在子布局中有按钮,这将不起作用。

不要忘记启用子可选属性

@Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
    // TODO Auto-generated method stub
    return true;
}

为我工作,有人知道为什么吗?这是虫子吗?据我所知这不是虫子。childView中的视图只捕获onClick()事件,因此该事件永远不会到达childView。(这就是那个从未被叫来过的孩子们的听众)
