我使用的是兼容包用我的Android应用程序SherlockFragments。收到此错误的片段
。 致命异常:主要
我加入这些片段在动作条福尔摩斯标签。运行后,应用程序成功,当我切换标签第一次它的正常工作,在第二次它给在onCreateView)上面的错误(..
java.lang.IllegalStateException:指定的子已具有父。您必须先对孩子的父母打电话removeView()
I'm using SherlockFragments in my Android application using the compatibility package. Getting this error for fragments
. FATAL EXCEPTION: main
java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.
I am adding these fragments as tabs in actionbar sherlock. After run the app successfully when i am switching tabs first time it's working fine, in second time it's giving the above error in onCreateView()..
这是对的onCreate code()
this is the code in onCreate()
private static final String AD_UNIT_STANDARD_BANNER = "/6253334/dfp_example_ad/banner";
private DfpAdView adView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
adView = new DfpAdView(getActivity(), AdSize.BANNER, AD_UNIT_STANDARD_BANNER);
adView.setAdListener(this);
}
这是code,我使用的片段onCreateView()。
this is the code i am using in fragment onCreateView().
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_chats, container, false);
listview = (ListView) view.findViewById(android.R.id.list);
RelativeLayout layout = (RelativeLayout) view.findViewById(R.id.chats_inner_layout);
adView.setId(111);
adView.loadAd(new AdRequest());
RelativeLayout.LayoutParams add_lp = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
add_lp.addRule(RelativeLayout.BELOW, adView.getId());
listview.setLayoutParams(add_lp);
//**** this is the line causing for error****/////
layout.addView(adView);
return view;
}
这是XML code以上片段
this is the xml code for above fragment
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/chats_main_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/app_lite_theme"
android:orientation="vertical" >
<RelativeLayout
android:id="@+id/chats_inner_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ListView
android:id="@android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"
android:scrollbars="none" />
</RelativeLayout>
</RelativeLayout>
这同样code,我使用的是没有任何问题工作正常片段。我面临的问题,只有片段。这里有什么问题吗?有人告诉
我的解决方案这一点。
this same code i am using for fragments that is working fine without any problems. i am facing problem with fragments only. What is the problem here ? anybody tell me solution for this.
推荐答案
我想出头错在这部分
listview.setLayoutParams(add_lp);
应该是
addView.setLayoutParams(add_lp);
