Question

以下是我的fragment_rate.xml布局XML文件：

<?xml version="1.0" encoding="utf-8"?>
<layout
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        tools:context=".view.ui.RateFragment"
        android:layout_height="match_parent">
    <FrameLayout
            android:layout_height="match_parent"
            android:layout_width="match_parent">
    </FrameLayout>
</layout>

当我编译它时，我遇到了这个特殊错误：

Android resource compilation failed
Output: /home/sparker0i/CurrencyConverter/app/build/intermediates/incremental/mergeDebugResources/stripped.dir/layout/fragment_rate.xml:10: error: duplicate attribute.

Command: /home/sparker0i/.gradle/caches/transforms-1/files-1.1/aapt2-3.2.1-4818971-linux.jar/d811e9cf0b30534b0c407565dcc71d36/aapt2-3.2.1-4818971-linux/aapt2 compile --legacy \
    -o \
    /home/sparker0i/CurrencyConverter/app/build/intermediates/res/merged/debug \
    /home/sparker0i/CurrencyConverter/app/build/intermediates/incremental/mergeDebugResources/stripped.dir/layout/fragment_rate.xml
Daemon:  AAPT2 aapt2-3.2.1-4818971-linux Daemon #0

从此错误消息开始，第10行解析为FrameLayout内部的layout_width引用。奇怪的事实是，当我交换layout_height和layout_width的引用时，在第10行仍然出现相同的错误。

如果有重复的错误，我在互换时应该在第9行收到错误消息，但是错误仍然在第10行。

请帮助我。

PS。听起来很奇怪，但是还有另一个用户面临类似的问题here

EDIT2：从构建文件夹中打开布局文件：

<?xml version="1.0" encoding="utf-8"?>






    <FrameLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent" android:tag="layout/fragment_rate_0" xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" tools:context=".view.ui.RateFragment" android:layout_height="match_parent">
    </FrameLayout>

Answer 1

在研究了<layout>标签之后，在我看来，该标签已被Data Binding之前用于here (about the usage of the <layout> tag)，并在Android Developers documentation (about how to use such tags)中有更详细的解释。

因此，我假设<layout>标记中的属性可能会在内部传递给父标记（在您的情况下为<FrameLayout>）。

因此，如果您不使用数据绑定，则可以删除<layout>标记并将这些属性重新分配给<FrameLayout>标记，或者只是删除XML命名空间（或xmlns个属性）。

Answer 2

在我的情况下，我误将<layout>标签赋予了ID。删除后，问题得以解决。

<layout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/layout">

  <android.support.constraint.ConstraintLayout
        android:id="@+id/cm1"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

Answer 3

我能够通过同时删除android:layout_width和android:layout_height属性来解决此问题。

Answer 4

您的绑定布局必须存在一些问题，请更正您的布局标签

即使交换属性后，Android资源编译也会失败
