java - Umano 的 SlidingUpPanelLayout : Got a weird error in XML when I used it

Question

这是错误:

Exception raised during rendering: com.android.layoutlib.bridge.MockView cannot be cast to android.view.ViewGroup
Exception details are logged in Window > Show View > Error Log
The following classes could not be instantiated:
- com.sothree.slidinguppanel.SlidingUpPanelLayout (Open Class, Show Error Log)
See the Error Log (Window > Show View) for more details.
Tip: Use View.isInEditMode() in your custom views to skip code when shown in Eclipse

java.lang.IllegalArgumentException: layout_gravity must be set to either top or bottom

最初我只是将项目直接克隆到我的计算机上。但是由于我对其进行了更改并希望使用 github 的应用程序来同步更改，因此我将其 fork 并添加到我的项目中。自从在我使用它的 XML 文件中，我得到了这个错误。

编辑:添加了错误的其余部分。我像这样定义 layout_gravity:

xmlns:sothree="http://schemas.android.com/apk/res-auto"
android:id="@+id/item_photo_pager_sliding_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="bottom"
android:background="@color/black"
sothree:collapsedHeight="32dp"
sothree:dragView="@+id/item_photo_pager_like_counter"
sothree:shadowHeight="4dp" >

Answer 1

我傻了

android:layout_gravity="bottom"

实际上应该是

android:gravity="bottom"
