将 vectorDrawables 与 androidx 一起使用的更新
update for using vectorDrawables with androidx
The solution given in this documentation page 似乎对 androidx 用户无效（我认为这是因为提到 android.support.v7.appcompat 没有被 androidx 用户使用，对吧？） .我可能弄错了，但添加了：vectorDrawables.useSupportLibrary = true 还有
static{
AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
}
与 xml 的 app:srcCopmat：
<ImageButton
android:id="@+id/imageButton4"
android:layout_width="26dp"
android:layout_height="0dp"
android:layout_marginEnd="8dp"
app:layout_constraintBottom_toBottomOf="@+id/imageButton5"
app:layout_constraintEnd_toStartOf="@+id/imageButton5"
app:layout_constraintTop_toTopOf="@+id/imageButton5"
app:srcCompat="@drawable/sync" />
没有帮助。它只会使应用程序崩溃。 logcat 显示：

这个错误实际上是合乎逻辑的，熟悉阅读 logcat 的人会在 5 分钟内找到它。
启用使用 vectorDrawables.useSupportLibrary = true 的矢量后，您以后必须使用 app:srcCompat= @drawable/xyz 引用 所有 矢量图像，如果您的任何 xml 文件改为使用 android:src="@drawable/vector 那么应用程序将崩溃，如上所示。
旁注：文档中提到的解决方案也适用于 androidx 用户，只是为了清楚。
The solution given in this documentation page 似乎对 androidx 用户无效（我认为这是因为提到 android.support.v7.appcompat 没有被 androidx 用户使用，对吧？） .我可能弄错了，但添加了：vectorDrawables.useSupportLibrary = true 还有

关于如何为 androidx 用户使用 Lollipop[=32= 下的版本vectorDrawables（或简单的矢量图像），稍微 运行 了解一下] 将是一个巨大的帮助。

这个错误实际上是合乎逻辑的，熟悉阅读 logcat 的人会在 5 分钟内找到它。
启用使用 vectorDrawables.useSupportLibrary = true 的矢量后，您以后必须使用 app:srcCompat= @drawable/xyz 引用 所有 矢量图像，如果您的任何 xml 文件改为使用 android:src="@drawable/vector 那么应用程序将崩溃，如上所示。
旁注：文档中提到的解决方案也适用于 androidx 用户，只是为了清楚。
