【问题描述】:
我正在尝试在协调器布局中对齐元素。代码如下:
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<LinearLayout
android:id="@+id/appbar"
android:layout_width="match_parent"
app:layout_anchorGravity="top"
android:layout_height="256dp"
android:fitsSystemWindows="true"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
android:background="@color/colorPrimary">
<LinearLayout
android:id="@+id/collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:orientation="vertical">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/cheese_ipsum" />
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="HAHAHA" />
</RelativeLayout>
</LinearLayout>
</LinearLayout>
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_anchorGravity="bottom|center"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:paddingTop="24dp">
<LinearLayout
style="@style/Widget.CardContent"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Info"
android:textAppearance="@style/TextAppearance.AppCompat.Title" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/cheese_ipsum" />
</LinearLayout>
<LinearLayout
style="@style/Widget.CardContent"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Friends"
android:textAppearance="@style/TextAppearance.AppCompat.Title" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/cheese_ipsum" />
</LinearLayout>
<LinearLayout
style="@style/Widget.CardContent"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Related"
android:textAppearance="@style/TextAppearance.AppCompat.Title" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/cheese_ipsum" />
</LinearLayout>
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
<android.support.design.widget.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="@dimen/fab_margin"
android:clickable="true"
android:src="@drawable/ic_discuss"
app:layout_anchor="@id/appbar"
app:layout_anchorGravity="bottom|right|end" />
</android.support.design.widget.CoordinatorLayout>
但我希望布局正确对齐,例如:
当我将第一个 linear layout 包含在 AppBarLayout 中时,就会发生这种情况。这不是解决此问题的正确方法。在coordinator layout 中对齐元素的正确方法是什么?
