推荐答案
java.lang.IllegalArgumentException:找不到ID为0x7f040034的视图(com.example.festipedia_logo:id/content_frame)片段Searchresult {44d17a28#0 id = 0x7f040034节日内容}
java.lang.IllegalArgumentException: No view found for id 0x7f040034 (com.example.festipedia_logo:id/content_frame) for fragment Searchresult{44d17a28 #0 id=0x7f040034 Fest Content}
您的 searchact.xml中没有ID为 content_frame 的 ViewGroup .
You do not have a ViewGroup with the id content_frame in your searchact.xml.
通常是 FrameLayout .
你有
ft.replace(R.id.content_frame,new Searchresult(querystr) , "Fest Content");
因此，您正在将片段替换/添加到作为ViewGroup的容器中.因此，您需要在xml中添加相同的内容.
So you are replacing/adding fragment to the container which is a ViewGroup. So you need to have the same in the xml.
在xml中保存
<FrameLayout
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</FrameLayout>
