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：

最佳答案
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，dimen是Dimension的缩写。
有关它的更多详细信息，请参见https://developer.android.com/guide/topics/resources/more-resources#Dimension
