当父活动结束TouchListView不工作 [英] TouchListView is not working when parent activity finishes

问题描述

我使用了一个 TouchListView 通过CommonWare，到目前为止，它的正常工作，但它无法在以下情况：

I'm using a TouchListView by CommonWare and so far it's working fine, But it fails in the following case:

• 活动A 有TouchListView和按钮添加一个项目，现在当我点击了一个按钮，
• b活动打开，一旦用户选择我打电话的项目完成终止 b活动
• 和它回来活动A 。

• activity A has a TouchListView and button to add an item , now when i click over a button,
• activity B opens up and once the user choose the item i am calling finish to end activity B
• and it comes back to activity A.

现在这里拖动ñ下降的 TouchListView 不工作，我的意思是项目越来越拖累，但不能够被放置在用户想要，我想了很多，但能没有找到一个方法来解决这个问题。

Now here drag n drop in TouchListView doesn't work I mean items are getting dragged but not able to be placed where a user wants, I tried a lot but could not find a way to fix it.

推荐答案

我怀疑你在做的onCreate一些设置（）当您返回到活动一，这不是获取调用，因为你进入它的第二个（以及随后的）通过onResume时间（s）（）。

I suspect you're doing some setup in onCreate() that's not getting called when you return to Activity A because you're entering it the 2nd (and subsequent) time(s) via onResume().

http://developer.android.com/reference/android/app/ Activity.html

BaseAdapter adapter;
List<myStuff> stuffs;

if (adapter == null) {
    adapter = new BaseAdapter()
    if (stuffs == null) {
        stuffs = new List<myStuff>();
    }
}

你会需要做这样的事情，并添加到列表中的onSaveInstanceState（你savedInstanceState包），那么挖掘出来活动时重新启动。

You're going to need to do something like that and add List to your savedInstanceState bundle in onSaveInstanceState() then dig it out when the activity restarts.
