我已经查看了与我的类似错误的其他问题，但他们似乎有点不同。
在logcat中我收到此错误。我不知道如何解决这个问题。

答案 0 :(得分：3)
正如异常所述，问题是由您的placeholder_offline.xml drawable引起的，其中显然包含<ScrollView>标记。
您无法在可绘制的XML中使用<ScrollView>（或任何其他View标签） - 您无意中将布局文件放在可绘制文件夹中，或者您需要重新评估您使用该可绘制文件的内容。
在您的情况下，您的placeholder_offline布局包含以下内容：
<ImageView
android:layout_width="@dimen/placeholder_image_size"
android:layout_height="@dimen/placeholder_image_size"
android:layout_marginBottom="@dimen/global_spacing_m"
android:adjustViewBounds="true"
android:scaleType="fitCenter"
android:src="@layout/placeholder_offline" />
android:src="@layout/placeholder_offline"属性无效 - android:src需要引用drawable，而不是布局。
