我一直在寻找几个小时的解决方案。我正在尝试构建一个 BodyMassIndex 计算器。我已经完成了程序(我认为),但是每次我尝试运行该应用程序时,它都会在模拟器上崩溃。最重要的是,布局预览不再显示。我仍在尝试了解日志中所有错误代码的含义。我认为这是我的 layout.xml 的问题,但我不确定。任何建议或想法将不胜感激!

请记住下面有关 TableLayout 的内容。

水平排列其子项的布局。TableRow 应始终用作 TableLayout 的子项。如果 TableRow 的父级不是 TableLayout,则 TableRow 将表现为水平 LinearLayout。

TableRow 的子项不需要在 XML 文件中指定 layout_width 和 layout_height 属性。TableRow 始终强制这些值分别为 MATCH_PARENT 和 WRAP_CONTENT。

我使用了您的布局并删除了一些属性。它现在正在工作。您可以做一件事,尝试将已删除的属性一一添加,并使用图形布局选项卡检查其有效性。

布局文件中存在一些问题。跨越表格行的错误和子高度。尝试使用此 xml。只需从表第 0 行复制粘贴相同的内容,它应该可以工作。
