Question

我已经遵循了使用Xamarin的教程，并且遇到了一个显示错误的问题：

Android.Views.InflateException：'二进制XML文件第2行：二进制XML文件第2行：您必须提供layout_height属性。'

我已经检查了我的代码很多次了，所有layout_height的属性都很好。如果我没有发现其他错误，你们可以帮忙并通知我吗？

这是我要调试的XML文件：

<?php

$cleanEmail = $_POST['cust']['email']
$_SESSION['cleanEmail'] = $cleanEmail;

?>

这是我的@ drawable / colorchoose xml文件：它只包含颜色参考

Answer 1

此处缺少height属性：

android.support.design.widget.TextInputEditText

Answer 2

您忘了在这里增加高度

<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>

您必须提供layout_height属性
