Android : can't add view programmatically in linearLayout android

Question

i have fragment that has scrollview as a parent of layout and in scrollview i have a LinearLayout . when i'm trying to programmatically add view to that LinearLayout but i get the error " The specified child already has a parent. You must call removeView() on the child's parent first."

this is my layout

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layoutDirection="ltr"
tools:context="ir.pnuopen5.application.fragment.LeaugeFragment">

<RelativeLayout
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin">

    <TextView
        android:id="@+id/tv_LeagueFragment_title_lastNews"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/last_news"
        android:textSize="17sp"
        android:layout_gravity="right"
        android:layout_alignParentTop="true"
        android:layout_alignRight="@+id/view1"
        android:layout_alignEnd="@+id/view1" />

    <View
        android:id="@+id/view1"
        android:layout_width="match_parent"
        android:layout_height="3dp"
        android:layout_marginTop="10dp"
        android:background="@color/line"
        android:layout_below="@+id/tv_LeagueFragment_title_lastNews"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/lv_LeagueFragment_lastNews"
        android:layout_below="@+id/view1"
        android:orientation="horizontal"/>

    ...

and this is my java code

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_leauge, container, false);

    ...

    LinearLayout newsListView = (LinearLayout)view.findViewById(R.id.lv_LeagueFragment_lastNews);
    View newsListRow;
    TextView title,time;


    for (int i = 0;i<newsList.size();i++){
        newsListRow  =  inflater.inflate(R.layout.list_news_row0, container, false);
        title = (TextView)newsListRow.findViewById(R.id.rowNewsTitle);
        time = (TextView)newsListRow.findViewById(R.id.rowNewsTime);
        title.setText(newsList.get(i).getTitle());
        time.setText(newsList.get(i).getTime());
        newsListView.addView(newsListView);
    }

    ...

    return view;
}

Answer 1

In the code snippet newsListView.addView(newsListView), you are adding a view to itself. I think what you meant to do was:

newsListView.addView(newsListRow);

...to put it back in context...

for (int i = 0;i<newsList.size();i++){
    newsListRow  =  inflater.inflate(R.layout.list_news_row0, container, false);
    title = (TextView)newsListRow.findViewById(R.id.rowNewsTitle);
    time = (TextView)newsListRow.findViewById(R.id.rowNewsTime);
    title.setText(newsList.get(i).getTitle());
    time.setText(newsList.get(i).getTime());
    newsListView.addView(newsListRow);
}
