FAB的片段布局与CoordinatorLayout冲突 [英] Fragment layout with FAB conflict with CoordinatorLayout
问题描述
我使用 MaterialDrawer 和MainDrawerActivity
替换了中的每个片段容器 FrameLayout
基于选定的项目,但是我想添加一个与CoordinatorLayout
交互的FAB(仅用于此片段),以便它可以处理很酷的动画.
Im using MaterialDrawer with a MainDrawerActivity
where I replace each fragment inside container FrameLayout
based on selected item, but I want to add a FAB (just for this fragment) that interacts with CoordinatorLayout
so it can handle cool animations.
MainDrawer布局:
MainDrawer layout:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:id="@+id/appBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="true"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?actionBarSize"
android:minHeight="?actionBarSize"
android:theme="@style/Toolbar"
app:layout_scrollFlags="scroll|enterAlways" />
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>
我如何替换每个片段:
try {
supportFragmentManager.beginTransaction().replace(R.id.container, FeedFragment()).commit()
} catch (e: IllegalStateException) {
Timber.i(e, "Fragment is still there.")
}
片段布局:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="@+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbarAlwaysDrawVerticalTrack="true"
android:scrollbars="vertical"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:listitem="@layout/feed_item" />
<android.support.design.widget.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|right"
android:layout_marginBottom="@dimen/spacing_medium"
android:layout_marginRight="@dimen/spacing_medium"
android:elevation="@dimen/elevation_little"
app:fabSize="normal"
app:layout_anchor="@+id/container"
app:layout_anchorGravity="bottom|right"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
app:srcCompat="@drawable/ic_add_white_18dp" />
</FrameLayout>
但是结果是FAB按钮位于底部栏的后面:
But as result the FAB button is behind bottom bar:
我正在尝试设置协调器布局属性(layout_anchor
和那些)以匹配主要布局ID,但是它不起作用...
为什么?
Im trying setting the coordinator layout attribues (layout_anchor
and those) to match the main layout ids but it is not working...
why?
推荐答案
在Activity中定义浮动操作按钮-当前,片段的容器被视为父容器.
Define the Floating Action Button within the Activity - currently the Fragment's container is considered the parent.
FAB应该是CoordinatorLayout
