我想在我的xml文件中使用android.support.design.widget.CoordinatorLayout，android.support.design.widget.AppBarLayout，android.support.design.widget.CollapsingToolbarLayout.在一个视图下放置一个视图的可能性是什么?
I want use android.support.design.widget.CoordinatorLayout , android.support.design.widget.AppBarLayout , android.support.design.widget.CollapsingToolbarLayout in my xml file. What are the possibilities to position a view below another view?
例如:ScrollView中ImageView下方的ScrollView位置.
for example : position ScrollView beneath ImageView in CoordinatorLayout.

推荐答案
我假设您正在尝试将视图放置在CollapsingToolbarLayout内部. CollapsingToolbarLayout扩展了FrameLayout，因此定位视图的唯一可能性是利用视图边距和重力.在您的情况下，您可以将ImageView定位为:
I assume you are trying to position views inside of the CollapsingToolbarLayout. The CollapsingToolbarLayout extends FrameLayout, so the only possibility is to position views is to utilize view margin and gravity. In your case you could position a ImageView like:
<ImageView
android:layout_width="match_parent"
android:layout_height="100dp"
android:layout_marginTop="140dp" <-height of the ScrollView
/>
如果您尝试将新的ImageView直接添加到CoordinatorLayout，则可以使用:
If you are trying to add the new ImageView directly to the CoordinatorLayout you can utilize a anchor:
<ImageView
android:layout_width="match_parent"
android:layout_height="100dp"
app:layout_anchor="@+id/post_text_layout" <-view to anchor the imageview
app:layout_anchorGravity="bottom" <- specifies edge of the anchor that should be used
android:layout_gravity="bottom" <- how to position this view relatively to the anchoring position
/>
