下面是我的脚本：

还有布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="vertical"
    android:background="#1de9b6">

  <View
   android:id="@+id/rect001" 
   android:layout_width="100dp"
   android:layout_height="100dp"
   android:background="#E7040F" />

  <TextView
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:id="@+id/my_text"/>
</LinearLayout>

我可以在没有 gradle 的情况下成功编译。但布局如下：

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.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:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#1de9b6">

  <View
      android:id="@+id/rect001"
      android:layout_width="100dp"
      android:layout_height="100dp"
      android:background="#E7040F"
      app:layout_constraintRight_toRightOf="parent"
      app:layout_constraintLeft_toLeftOf="parent"/>

  <TextView
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:id="@+id/my_text"
      app:layout_constraintRight_toRightOf="parent"
      app:layout_constraintLeft_toLeftOf="parent"/>
</androidx.constraintlayout.widget.ConstraintLayout>

我无法编译：

Generate ./build/gen/ecl/android/skeleton/R.java file...
    (skipping file '.#main.xml' due to ANDROID_AAPT_IGNORE pattern '.*')
res/layout/main.xml:10: error: No resource identifier found for attribute 'layout_constraintRight_toRightOf' in package 'ecl.android.skeleton'

res/layout/main.xml:10: error: No resource identifier found for attribute 'layout_constraintLeft_toLeftOf' in package 'ecl.android.skeleton'

res/layout/main.xml:18: error: No resource identifier found for attribute 'layout_constraintRight_toRightOf' in package 'ecl.android.skeleton'

res/layout/main.xml:18: error: No resource identifier found for attribute 'layout_constraintLeft_toLeftOf' in package 'ecl.android.skeleton'

所以，我知道我需要将约束布局库添加到aapt 命令，但我不知道我需要添加哪个或哪些文件以及将其放在哪里。

总结：

在哪里下载需要添加的文件？
我需要在appt 命令中添加什么文件？

在哪里下载需要添加的文件？

我现在可以下载 lib 文件了：

https://dl.google.com/dl/android/maven2/androidx/constraintlayout/constraintlayout/2.0.0-beta4/constraintlayout-2.0.0-beta4.aar

但我不知道我必须在脚本的哪个位置添加constraintlayout-2.0.0-beta4.aar 文件。

在哪里下载需要添加的文件？

我认为需要做很多事情：

解压 .aar lib 文件。

首先我检查 lib 文件：

# unzip -Z1 constraintlayout-2.0.0-beta4.aar

AndroidManifest.xml
R.txt
classes.jar
res/
res/values/
res/values/values.xml
values/

所以，解压这个：

# unzip -d constraintlayout-2.0.0-beta4 constraintlayout-2.0.0-beta4.aar

将 lib AndroidManifest.xml 与应用 AndroidManifest.xml 合并。

我现在是手动完成的。

在aapt命令中添加lib res/生成R.java文件吧。

我更改了构建脚本以添加约束布局库的 res/：

echo "Generate ./build/gen/${ORG_DIRS}/R.java file..."
"${BUILD_TOOLS}/aapt" package --auto-add-overlay -f -m -J build/gen/ \
              -S res \
              -S "${ANDROIDX_LIBS}"/constraintlayout-2.0.0-beta4/res \
              -M AndroidManifest.xml -I "${PLATFORM}/android.jar"

它似乎有效，我不再收到错误。

在javac命令中添加lib的classes.jar。

我可以编译：

echo "Compiling the java files in ./build/obj/*.class..."
javac -bootclasspath "${JAVA_HOME}/jre/lib/rt.jar" \
      -classpath "${PLATFORM}/android.jar":"${ANDROIDX_LIBS}"/constraintlayout-2.0.0-beta4/classes.jar \
      -d build/obj \
      build/gen/"${ORG_DIRS}"/R.java \
      src/"${ORG_DIRS}"/EmbeddedCommonLisp.java \
      src/"${ORG_DIRS}"/HelloEclActivity.java

但我无法打包应用程序。错误信息：

# ...

res/layout/main.xml:19: error: No resource identifier found for attribute 'layout_constraintLeft_toLeftOf' in package 'ecl.android.skeleton'

当我将第 4 行的 main.xml 文件更改为：

xmlns:app="http://schemas.android.com/apk/ecl.android.skeleton"

我可以创建 apk，但是当我在手机中测试时，它坏了。 adb 错误：

03-24 09:41:05.420 19978 19978 E AndroidRuntime: Caused by: android.view.InflateException: Binary XML file line #2: Binary XML file line #2: Error inflating class androidx.constraintlayout.widget.ConstraintLayout

03-24 09:41:05.420 19978 19978 E AndroidRuntime: Caused by: java.lang.ClassNotFoundException: Didn't find class "androidx.constraintlayout.widget.ConstraintLayout" on path: DexPathList[[zip file "/data/app/ecl.android.skeleton-2/base.apk"],nativeLibraryDirectories=[/data/app/ecl.android.skeleton-2/lib/arm, /data/app/ecl.android.skeleton-2/base.apk!/lib/armeabi-v7a, /vendor/lib, /system/lib]]

03-24 09:41:05.420 19978 19978 E AndroidRuntime:    Caused by: java.lang.NoClassDefFoundError: Class not found using the boot class loader; no stack trace available

03-24 09:41:05.426  1796  2936 W ActivityManager:   Force finishing activity ecl.android.skeleton/.HelloEclActivity

所以我在dex 步骤中添加了库：

echo "Creating ./build/apk/classes.dex..."
"${BUILD_TOOLS}/dx" --dex --output=build/apk/classes.dex \
            "${ANDROIDX_LIBS}"/constraintlayout-solver-2.0.0-beta4.jar \
            "${ANDROIDX_LIBS}"/constraintlayout-2.0.0-beta4/classes.jar \
            build/obj/

我需要添加“constraintlayout-solver-2.0.0-beta4.jar”，因为在此错误之前我收到了一个抱怨此错误的错误。

我现在得到了其他：

03-25 10:20:01.401 12274 12274 E AndroidRuntime: Caused by: java.lang.ClassNotFoundException: Didn't find class "androidx.constraintlayout.widget.R$styleable" on path: DexPathList[[zip file "/data/app/ecl.android.skeleton-2/base.apk"],nativeLibraryDirectories=[/data/app/ecl.android.skeleton-2/lib/arm, /data/app/ecl.android.skeleton-2/base.apk!/lib/armeabi-v7a, /vendor/lib, /system/lib]]

我看到constraintlayout-solver-2.0.0-beta4.jar没有androidx.constraintlayout.widget.R$styleable这个类：

所以，我现在不知道，我认为需要生成某种方式的androidx.constraintlayout.widget.R$styleable。

出了什么问题？

我在 apk R.java 文件中添加了约束布局库的 res/，因为我需要将 lib R.java 文件分开编译。因此，使用javac 编译所有R.java 文件，在dex 命令中添加所有.class 文件。并且有效。
