我想要將視圖錨定在AppBarLayout和佈局之間。我只在Android Studio編輯器上得到這種行爲,但在真實設備上是這樣的: 工具欄和佈局之間的layout_anchor
我真的很困惑。我的代碼是:
<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>
不知道的代碼,但我想改變「AvatarView」的標高比AppBarLayout更應該工作 –
@AjilO。你是什麼意思_改變高程_?我把'app:layout_anchor =「@ + id/whole_layout」 app:layout_anchorGravity =「top | start」'實現所需的行爲 – Choletski
是的。但'whole_layout'會放在'AppBarLayout'下面。我沒有確認;但我相信'AppBarLayout'默認情況下的海拔高度爲8dp。當你的LinearLayout('whole_layout')在0dp標高時。並且您試圖錨定的'RelativeView'默認情況下也會將其作爲0dp提升 –
