我在尝试使用style="Widget.AppCompat.Button.Colored"时遇到错误。使用android支持库版本23.2.1。
我的xml文件：
<Button
android:layout_width = "140dp"
android:layout_height = "90dp"
android:text = "Camera"
android:id = "@+id/cameraButt"
android:textAllCaps = "false"
android:textColor = "@color/textColorPrimary"
android:layout_marginLeft = "5sp"
android:layout_marginRight = "5sp"
android:layout_marginTop = "4sp"
style="@style/Base.Widget.AppCompat.Button.Colored"/>
它在5.0 ++版本中完美运行，但在棒棒糖前没有。
logcat的：

请将此添加到您的gradle依赖项中，看看它是否有效并让我知道
compile 'com.android.support:design:23.2.1'
