＆QUOT;指定的子已具有父＆QUOT;错误 [英] "specified child already has a parent" error

问题描述

我有一个页面将显示价值选定运动的预定游戏一个星期。选定的运动和周被存储即在页面的开始打开一个XML文件中。当我点击下周链接，新的一周的日期值存储到该XML文件，然后在页面现在应该显示这个下周reloaded.Any游戏。这些游戏都显示在一个tablelayout根据需要将.java页面，在这里我以编程方式创建的行。
这里是code的简化样本。

I have a page that will display a weeks worth of scheduled games for a selected sport. The selected sport and week is stored within a XML file that is opened at the the start of the page. When I click on the next week link, a new week date value is stored to this xml file and then the page is reloaded.Any games for this next week should now be displayed. These games are displayed in a tablelayout where I programmatically create the rows as needed in the .java page. Here is a simplified sample of the code.

TableLayout tlGames = (TableLayout)findViewById(R.id.table_games);

for (int i = 0; i < gameCount; i++) 
{

TableRow trGameHomeTeam = new TableRow(this);

TextView tvHomeTeamName = new TextView(this);

tvHomeTeamName.setText("Home Team Name Here");

tvHomeTeamName.setLayoutParams(new LayoutParam (LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));

TextView tvHomeTeamScore = new TextView(this);

tvHomeTeamScore.setText("Home Team Score Here");

tvHomeTeamScore.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));

trGameHomeTeam.addView(tvHomeTeamName);

trGameHomeTeam.addView(tvHomeTeamScore);

tlGames.addView(trGameHomeTeam,new TableLayout.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));

}           

当我最初运行我的应用程序，为当前日期场均正确列出。然后，一旦我点击下周链接，它应该repload这个页面，并显示该新的一周的比赛。相反，我得到一个错误消息指定的孩子已经有了父母，你必须在孩子的父母先调用removeView（）。我添加了一个tlGames.removeAllViews（）;该TableLayout tlGames线后立即但这并没有纠正错误。

When I initially run my app, the games for the current date are listed properly. Then once I click on the next week link, it should repload this page and display the games for this new week. Instead, I get an error message of "The specified child already has a parent. You must call removeView() on the child's parent first." I added a "tlGames.removeAllViews();" immediately after the TableLayout tlGames line but this did not correct the error.

唯一的地方是我有addView是表中的行创建表行或textviews。

The only places were I have the "addView" is for creating table rows or the textviews in the table rows.

谁能告诉我什么，我做错了什么？

Can anyone tell me what I am doing wrong?

感谢

推荐答案

我的猜测是，与页面的重新加载到这个星期显示的游戏中，你使用布局充气膨胀的细节布局？

My guess is that with the reloading of the page to display the games for this week, you use a layout inflater to inflate the details layout?

布局充气是我见过这个错误发生的唯一的地方，如果是这样的情况下，通过虚假的第三个参数到充气的方法，因为它会试图以其他方式虚增您的视图的根，这样就扔此异常回你。

The layout inflater is the only place I've seen this error occur, if that is the case, pass a third argument of false to the inflate method, as it will attempt to inflate the root of your view otherwise, thus throwing this exception back at you.

即

inflater.inflate(R.layout.profile, container, false);
