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.support.constraint.ConstraintLayout

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>
最佳答案
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>
关于android - 您必须提供 layout_height 属性，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/58386048/
