error in xml
check that you are in line 17 of your submission.
xml 中的错误
检查您是否在提交的第 17 行。
android:attr/textAppearanceListItemSmall
if the error here is api level change in the manifest
android:attr/textAppearanceListItemSmall
如果这里的错误是清单中的 api 级别更改
回答by molnarm
The innermost exception means that one of your textviews have invalid dimensions declared. Check the SDK level you are using, because android:attr/listPreferredItemHeightSmalland android:attr/textAppearanceListItemSmallare available from API level 14 and up.
最里面的异常意味着您的文本视图之一声明了无效的尺寸。检查您正在使用的 SDK 级别，因为android:attr/listPreferredItemHeightSmall和android:attr/textAppearanceListItemSmall可用于 API 级别 14 及更高版本。

I found the same error on the same line, and it took two days to identify what the error was.
我在同一行上发现了同样的错误，花了两天时间才确定错误是什么。
The error was simply because I was trying to use one: android:background
错误只是因为我试图使用一个： android:background
Rather than: app:srcCompat
而不是： app:srcCompat
in an SVG file.
在 SVG 文件中。
In your case,
在你的情况下，
<ImageView android:id="@+id/icon"
android:layout_width="25dp"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_marginLeft="12dp"
android:layout_marginRight="12dp"
android:src="@drawable/menu_tip" <-- the error is here
android:layout_centerVertical="true"/>
the error also appears if you are using: android:src=" "
如果您正在使用，也会出现该错误： android:src=" "
I hope this helps.
我希望这有帮助。
