android - 您必须提供 layout_height 属性

Question

我已经学习了使用 Xamarin 的教程，但我遇到了一个问题，它一直显示错误:

Android.Views.InflateException: 'Binary XML file line #2: Binary XML file line #2: You must supply a layout_height attribute.'

我已经检查了我的代码很多次了，layout_height 的所有属性都很好。如果还有其他我没有看到的错误，你们能帮忙通知我吗？

这是我要调试的 XML 文件:

            android:inputType="textEmailAddress"/>
    </android.support.design.widget.TextInputLayout>
</android.support.constraint.ConstraintLayout>

这是我的@drawable/colorchoose xml 文件:它只包含颜色引用

<?xml version="1.0" encoding="utf-8" ?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item>
    <shape>
      <gradient
          android:startColor="#ffff"
          android:endColor="#ffac"
          android:angle="45"/>
    </shape>
  </item>
</selector>

你忘了在这里添加高度:

<android.support.design.widget.TextInputEditText
            android:id="@+id/etPassword"
            android:layout_width="match_parent"
            android:textColor="#fff"
            android:hint="Password"
            android:inputType="textPassword"/>
    </android.support.design.widget.TextInputLayout>
