找不到片段ID的视图（在listView中）
[英]No view found for id for fragment (in listView)
问题描述
我是一个长期的stackOverflow潜行者，并且是第一次海报，所以如果我错过任何步骤或要求，我深表歉意。 我已经在此bug上停留了2个星期，并且已经在网上广泛搜索了相关的bug，但是没有任何解决方案能够解决我的问题，所以我希望你们中的一个可以帮助您对此有所了解！ 奇怪的是，它曾经可以正常工作，并且我没有对代码进行任何更改，因此它要么是我只是没赶上的过时API，要么就是其他。
我有一个ListView，其中一个列表项包含一个带有地图的片段。 加载ListView时，出现此崩溃：

您将错误的上下文指向fragmentTransaction 。 尝试以下方法。 您可以使用view.getContext()获得视图的上下文。
如下所示更新
LocationFormCell构造函数。
public LocationFormCell(Context ctx, CSFormElement elem, FormFragment frag, boolean editable) {
super(ctx, elem, frag, editable);
View view = LayoutInflater.from(ctx).inflate(R.layout.form_element_location, this);
Button overlayButton;
overlayButton = (Button) view.findViewById(R.id.overlayButton);
setupOnClickListener(overlayButton);
locationFrag = LocationMapFragment.newInstance(formElement.disp_name,false);
FragmentTransaction ft = ((FragmentActivity)view.getContext()).getSupportFragmentManager().beginTransaction();
ft.add(R.id.map_container, locationFrag);
ft.commitAllowingStateLoss();
locationFrag.setValue(value);
}
