甚至无法解决。 Might be there is an issue regarding layout_anchor but don't know what is the problem.
关于layout_anchor可能存在问题,但不知道是什么问题。
Here is there code: 这里是代码:

</android.support.v4.widget.DrawerLayout>
Can anyone help me to resolve this issues? 谁能帮我解决这个问题? What is the reason why it is not getting on bottom right side?
它为什么不在右下角的原因是什么?
Your FloatingActionButton
should be like this: 您的
FloatingActionButton
应该是这样的:
<android.support.design.widget.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="16dp"
android:layout_gravity="bottom|end" />
You don't need to use anchor
to place it inside the CoordinatorLayout
. 您无需使用
anchor
将其放置在CoordinatorLayout
。 Anchor
and AnchorGravity
only used for anchor the view to another sibling view. Anchor
和AnchorGravity
仅用于将视图锚定到另一个同级视图。
