【问题描述】:
我有以下 XML:
<android.support.design.widget.CoordinatorLayout
android:id="@+id/sliding_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@id/app_bar">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
<fragment
android:id="@+id/fragment1"
android:name="com.xyz.Fragment1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
tools:layout="@layout/fragment_layout1" />
</LinearLayout>
<LinearLayout
android:id="@+id/layoutBottomSheet"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:elevation="@dimen/global_margin"
android:orientation="vertical"
app:layout_behavior="@string/bottom_sheet_behavior">
<fragment
android:id="@+id/fragment2"
android:name="com.xyz.Fragment2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center|top"
tools:layout="@layout/fragment_layout2" />
</LinearLayout>
<android.support.design.widget.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginEnd="@dimen/global_margin"
android:layout_marginRight="@dimen/global_margin"
android:src="@drawable/ic_add_white_24dp"
app:borderWidth="0dp"
app:elevation="4dp"
app:layout_anchor="@id/layoutBottomSheet"
app:layout_anchorGravity="top|right|end" />
</android.support.design.widget.CoordinatorLayout>
布局应显示为Fragment1,然后在Fragment2 下方,FAB 锚定到Fragment2,但在Fragment2,而不是在它.
其实它显示为,
出了什么问题?有什么想法吗?
