Question

请帮助，不能弄清楚如何解决我遇到的这个问题。这些是我可以提供给您的所有信息：我的 activity_main.xml ：

android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"

和 dimen.xml ：

<dimen name="activity_horizontal_margin">activityhorizontalmargin</dimen>
<dimen name="activity_vertical_margin">activityverticalmargin</dimen>

错误日志：

Answer 1

dimen.xml 中的值不正确：

<dimen name="activity_horizontal_margin">activityhorizontalmargin</dimen>
<dimen name="activity_vertical_margin">activityverticalmargin</dimen>

应该是这样的：

<dimen name="activity_horizontal_margin">10dp</dimen>
<dimen name="activity_vertical_margin">10dp</dimen>

请注意，维度是维度的缩写。

Answer 2

您是否尝试在gradle.properties文件中去除aapt2

:android.enableAapt2=false

任务'：app：mergeDebugResources'的执行失败。错误：无效的维数
