android.view.InflateException：二进制 XML 文件行（不存在）

Question

我有这样的布局：

<?xml version="1.0" encoding="utf-8"?>
<merge>
  <android.support.constraint.ConstraintLayout
      xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto"
      xmlns:tools="http://schemas.android.com/tools"
      android:id="@+id/has_selected_account"
      android:layout_width="match_parent"
      android:layout_height="wrap_content">

    <TextView
        android:id="@+id/account_display_name"
        android:layout_width="wrap_content"
        android:layout_marginTop="@dimen/account_menu_name_and_display_vertical_padding"
        android:layout_marginBottom="@dimen/account_menu_name_and_display_vertical_padding"
        app:layout_constraintBottom_toTopOf="@+id/account_name"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintVertical_chainStyle="packed"
        tools:text="DisplayNameIsLongSoItShouldBeTruncatedAtSomePoint"/>
    <TextView
        android:id="@+id/account_name"
        android:layout_width="wrap_content"
        android:layout_marginTop="@dimen/account_menu_name_and_display_vertical_padding"
        android:layout_marginBottom="@dimen/account_menu_name_and_display_vertical_padding"
        android:includeFontPadding="false"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/account_display_name"
        tools:text="emailisverylongaswellwewantittogettruncated@gmail.longdomain.com"/>
  </android.support.constraint.ConstraintLayout>
</merge>

我得到一个非常普遍的 inflation 错误：

 Caused by: android.view.InflateException: Binary XML file line #39: Error inflating class com.me.AccountParticle
    at android.view.LayoutInflater.createView(Layo

（剪成这样）

我试图简化我的 XML。我该如何解决 inflation 错误？

加上我的布局 XML 不像 #39 那么这是指哪里呢？

Answer 1

您缺少 android:layout_height 两个 TextView，这就是您如何获得视图 inflation 错误。当视图被膨胀时，它需要通过另一个 class 或方法来解析 merge 标记，这似乎有不同的解析错误的方式。否则你会看到一个更清晰的错误，缺少 android:layout_height。

Answer 2

请使用这个。

<?xml version="1.0" encoding="utf-8"?>
<merge>
  <android.support.constraint.ConstraintLayout

      xmlns:tools="http://schemas.android.com/tools"
      android:id="@+id/has_selected_account"
      android:layout_width="match_parent"
      android:layout_height="wrap_content">

    <TextView
        android:id="@+id/account_display_name"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="@dimen/account_menu_name_and_display_vertical_padding"
        android:layout_marginBottom="@dimen/account_menu_name_and_display_vertical_padding"
        app:layout_constraintBottom_toTopOf="@+id/account_name"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintVertical_chainStyle="packed"
        tools:text="DisplayNameIsLongSoItShouldBeTruncatedAtSomePoint"/>
    <TextView
        android:id="@+id/account_name"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="@dimen/account_menu_name_and_display_vertical_padding"
