我想要将视图锚定在AppBarLayout和布局之间。我只在Android Studio编辑器上得到这种行为,但在真实设备上是这样的: 工具栏和布局之间的layout_anchor
我真的很困惑。我的代码是:
<android.support.design.widget.CoordinatorLayout 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"
tools:context="view.activity.MainActivity">
<android.support.design.widget.AppBarLayout
android:id="@+id/bar_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="@style/AppTheme.PopupOverlay" />
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginStart="84dp"
android:layout_marginTop="@dimen/activity_vertical_margin">
<!--views on toolbar-->
</RelativeLayout>
</android.support.design.widget.AppBarLayout>
<include layout="@layout/activity_home_content" />
<RelativeLayout
android:layout_width="60dp"
android:layout_height="60dp"
android:layout_marginStart="@dimen/activity_horizontal_margin"
android:background="@drawable/circle_accent"
app:layout_anchor="@+id/whole_layout"
app:layout_anchorGravity="top|start">
<!--img view-->
</RelativeLayout>
</android.support.design.widget.CoordinatorLayout>
和 'activity_home_content'
<LinearLayout 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:id="@+id/whole_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:context="view.activity.MainActivity"
tools:showIn="@layout/activity_home_toolbar">
<!--some other views-->
</LinearLayout>
不知道的代码,但我想改变“AvatarView”的标高比AppBarLayout更应该工作 –
@AjilO。你是什么意思_改变高程_?我把'app:layout_anchor =“@ + id/whole_layout” app:layout_anchorGravity =“top | start”'实现所需的行为 – Choletski
是的。但'whole_layout'会放在'AppBarLayout'下面。我没有确认;但我相信'AppBarLayout'默认情况下的海拔高度为8dp。当你的LinearLayout('whole_layout')在0dp标高时。并且您试图锚定的'RelativeView'默认情况下也会将其作为0dp提升 –
