工具栏上方的可绘制面板

Question

我的活动包含 - Toolbar，Tabs，ViewPager，FloatingActionButton和DraggablePanel。

当我初始化我的可拖动面板时，它出现在Toolbar,FloatingButton和Tabs之下。设置DraggablePanel.bringToFront()只会使其高于ViewPager。如何在初始化时将我的DraggablePanel高于一切？

尝试将海拔，更高的价值比你FAB设为您的DraggablePanel

<com.github.pedrovgs.DraggablePanel 
    android:id="@+id/draggable_panel" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:elevation="10dp" 
    draggable_panel:x_scale_factor="2.3" 
    draggable_panel:y_scale_factor="2.3" 
    draggable_panel:top_fragment_height="200dp" 
    draggable_panel:top_fragment_margin_right="10dp" 
    draggable_panel:top_fragment_margin_bottom="10dp" 
    draggable_panel:enable_horizontal_alpha_effect="true"/>
