onClickListener是影响到Android的ExapndabaleListView所有子项getChildView项目 [英] getChildView items onClickListener is effecting to all child items in ExapndabaleListView Android
本文介绍了onClickListener是影响到Android的ExapndabaleListView所有子项getChildView项目的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
请看看这个画面：
![请看接受按钮图像](\"http://i.stack.imgur.com/xPm60.png\")
当我点击接受变更为另一个按钮：
![我点击接受chnaged到另一个按钮图像](\"http://i.stack.imgur.com/4frDw.png\")
如果我点击在扩展列表视图有一个 getChildView 列表项，它也影响到其他子项，同时滚动屏幕。在这里，我改变按钮上的文字，当我点击 getChildview 项目
在这里，我点击接受一个孩子的按钮，那么它应该更改为另一个按钮，但滚动时所有子项中的按钮也改变

解决方案
从我所看到的问题是，你不使用你的onclick方法的观点，使您的用户界面所需要的变化。所以，问题是上下文这里。 Holder对象被创建和销毁每个组，你应该使用v从公共无效的onClick（视图V）作出总是UI的任何变化，无论是对儿童的意见组头点击。
PS。我建议有一个模型中的异步任务的变化数据并调用notifydatasetchanged（）的适配器上返回的成功。
干杯
Please look into this screen:
And when I click on accept changed to another button:
if I click on one getChildView List item in expandable list-view,it is also effecting to other child item while scrolling the screen. Here I changed button text when I click the getChildview item
Here I am clicking on accept button of one child ,then it should change to another button but while scrolling all child items buttons also changing

解决方案
From what I can see the problem is that you aren't using the view in your onclick method to make the changes required in your UI. So the problem is context here. Holder object is created and destroyed for each group and you should use v from public void onClick(View v) to make any changes to the UI always, be it for the click on the group header of child views.
PS. I would suggest to have the Async task change data in a Model and just call notifydatasetchanged() on the adapter on returning a success.
Cheers
