我的片段有scrollview作为布局的父级,在scrollview中我有一个LinearLayout。当我试图以编程方式向该LinearLayout添加视图但我收到错误“指定的孩子已经有父。你必须首先在孩子的父母上调用removeView()。”
这是我的布局
<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"/>
...
这是我的java代码
@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;
}

在代码段newsListView.addView(newsListView)
中,您要为自己添加视图。我想你的意思是:
newsListView.addView(newsListRow);
......把它放回上下文......
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);
}

您应该使用动态视图。
以下是您的回答
for(int i = 0;i<newsList.size();i++) {
LinearLayout newsListRow = new LinearLayout(this);
TextView title = new TextView(this);
TextView time = new TextView(this);
title.setText(newsList.get(i).getTitle());
time.setText(newsList.get(i).getTime());
newsListRow.addView(title);
newsListRow.addView(time);
newsListView.addView(newsListView);
}
您可以添加LayoutParameter,使其看起来像静态行视图。

在添加视图之前,请通过调用
将其删除newsListView.removeView(view);
