Android Fragment找不到ID的视图?

Android Fragment no view found for ID?(Android Fragment找不到ID的视图?)

问题描述

我有一个片段要添加到视图中.

I have a fragment I am trying to add into a view.

FragmentManager fragMgr=getSupportFragmentManager();
feed_parser_activity content = (feed_parser_activity)fragMgr
                                    .findFragmentById(R.id.feedContentContainer);
FragmentTransaction xaction=fragMgr.beginTransaction();

if (content == null || content.isRemoving()) {
    content=new feed_parser_activity(item.getLink().toString());
    xaction
        .add(R.id.feedContentContainer, content)
        .setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN)
        .addToBackStack(null)
        .commit();
    Log.e("Abstract", "DONE");
}

执行此代码时，我在调试中收到以下错误..

When this code is executed I get the following error in debug..

java.lang.IllegalArgumentException: No view found for id 0x7f080011 
   for fragment feed_parser_activity{41882f50 #2 id=0x7f080011}

feed_pa​​rser_activity 是在 xml 中设置为 Fragment 布局的 Fragment.
我正在使用 FragmentActivity 来托管包含 feed_pa​​rser_layout 的片段布局.
我上面的编码是否正确?

feed_parser_activity is a Fragment that is set to Fragment layout in xml.
I am using a FragmentActivity to host the Fragment Layout holding the feed_parser_layout.
Am I coding this correctly above?

推荐答案

解决方案是使用 getChildFragmentManager()

而不是 getFragmentManager()

从片段调用时.如果您从活动中调用该方法，请使用 getFragmentManager().

when calling from a fragment. If you are calling the method from an activity, then use getFragmentManager().

这样就解决了问题.
