< TableLayout>< TableRow>< LinearLayout>讨厌我.强制关闭运行.安卓 [英] <TableLayout><TableRow><LinearLayout> hates me. Force close on run. Android

问题描述

全部.我正在为Android应用程序设置主屏幕布局，其中有一个4x4的启动图标网格.我目前的结构如下:

all. I'm working on setting up a home screen layout for an Android app in which there is a 4x4 grid of launch icons. My current structure for this is like this:

<TableLayout>
  <TableRow>
    <LinearLayout android:orientation="vertical">
      <ImageButton>
      <TextView>
    </LinearLayout>
  </TableRow>
  ...
  ...
  ...
</TableView>

运行此命令时，我会立即强制关闭.如果我从等式中删除LinearLayout，它可以工作，但是我没有得到想要的对齐方式.将线性布局放置在工作台内部是否存在本质上的问题?还是这里可能还有其他事情?据我所知，我的xml都是有效的，并且我认为自己具有所需的所有必需属性.这有点使我发疯，因为似乎没有关于此设置的任何文档.

When I run this, I get a force-close immediately. If I remove the LinearLayout from the equation, it works, but I don't get the alignment I want. Is there something inherently wrong with putting a linearlayout inside of a tablerow? Or is there probably something else going on here? As far as I can tell, my xml is all valid and I think I have all the required attributes I need. This is kind of driving me nuts, as there does not appear to be any documentation about this setup.

推荐答案

我几次也遇到相同的问题，通常这是缺少的布局属性，例如android:layout_height之类的东西.正如已经提到的那样，建议您继续检查日志，以查看到底是什么引起了该问题. TableLayout(即TableRow)中的LinearLayout或RelativeLayout的结构通常可以很好地工作-即使我没有经验说这样做是否是最佳实践.

I had the same problem a few times myself and usually it is a missing layout property such as android:layout_height or something. As it has already been mentioned it is advisable to just go ahead and check your logcat to see what exactly is causing the problem. A structure of a LinearLayout or RelativeLayout within a TableLayout (i.e. TableRow) however generally works out fine - even though I do not have the experience to say if it is best practice to do so.
