android-layout - 您必须提供 layout_width 属性异常

Question

我有一个布局，它在底部的前 2 个按钮上有标题，中间有一些 TextView 和编辑文本。我愿意将这些 EditText 和 Text View 放在 ScrollView 中，以便我可以滚动并且 EditText 不会隐藏在键盘后面。

这是我的 XML 文件，很抱歉它有点冗长，但是请查看此文件并让我知道这有什么问题。我总是得到
java.lang.RuntimeException:二进制 XML 文件第 73 行:您必须提供 layout_width 属性。
我试过很多方法改变宽度和高度，但我总是得到这个错误。

Answer 1

你的 ScrollView 有 android.layout_width 而不是 android:layout_width ...类似的 layout_height

观察点而不是冒号

那可能是你的问题
