Question

手机上的Android Studio运行代码会自动关闭。我正在尝试构建一个翻译器应用程序。我认为我的布局设计有问题，但我无法弄清楚是什么。

我把我的主页分为两部分。

这是我的activity_home布局。

你能告诉我出了什么问题吗？

Answer 1

我认为这是因为约束布局.Constraint布局是Android的新布局，你可以在其中拖放按钮，textview等所有但它可能在预览中看起来很完美而在手机中看起来不是很好，因为每个设备都有不同的大小显示屏幕，因此约束布局将在不同的Android手机中工作不同，您可能也会在该布局文件中收到警告或错误。因此尝试使用LinearLayout或RelativeLayout，然后错误将不会出现。

android studio运行代码在手机上自动关闭。我认为我的布局设计有问题，但我无法弄清楚为什么
