    </android.support.constraint.ConstraintLayout>


</android.support.constraint.ConstraintLayout>

在库中找到它，然后发布库并尝试在我的应用中使用使用此布局的片段

出现该片段但没有按钮的情况

谁能告诉我可能是什么问题？

编辑这是活动的布局，应包含先前的Fragment布局

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/white"
android:layoutDirection="ltr">

<include
    android:id="@+id/actionbar"
    layout="@layout/item_actionbar" />

<LinearLayout
    android:id="@+id/seperator"
    android:layout_width="match_parent"
    android:layout_height="0.5dp"
    android:layout_below="@+id/actionbar"
    android:background="@color/action_bar_seperator_color"
    android:orientation="horizontal"></LinearLayout>


<FrameLayout
    android:id="@+id/dynamic_fragment_frame_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@+id/seperator" />

EDIT2

这是应该显示的布局，但它不是这样，它没有添加和音频按钮。

从ConstraintLayout-android:visibility="invisible"删除此行
