工具栏上方的可绘制面板

Question

我有一个 activity 包含 - Toolbar、Tabs、ViewPager、FloatingActionButton 和 DraggablePanel。

当我初始化可拖动面板时，它出现在 Toolbar、FloatingButton 和 Tabs 下方。设置 DraggablePanel.bringToFront() 使其仅高于 ViewPager。如何在初始化时让我的 DraggablePanel 高于一切？

尝试为 Draggable Panel 设置比 FEB 更高的值 elevation

 <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"/>
