方形浮动动作按钮 [英] Floating Action Button with square shape
问题描述
当我为工厂设置颜色时,它看起来像这样:
When I set a color to my fab, it looks like so:
我的布局xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"
tools:context=".MainActivity$PlaceholderFragment">
<android.support.design.widget.FloatingActionButton
android:id="@+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_add"
android:layout_marginRight="20dp"
app:fabSize="normal"
android:elevation="@dimen/fab_elevation"
android:background="#000000"
android:stateListAnimator="@animator/fab_anim"
android:layout_gravity="center_horizontal"
android:layout_alignParentBottom="true"
android:layout_alignParentEnd="true" />
颜色也不会更改。
有人可以帮助我了解我在做什么吗?
Also the color doesn't change. Can anyone help me in understanding what I am doing wrong?
我也尝试过使用 @color
链接,但它以可绘制(例如android:background = @ drawable / fab_background)的背景崩溃了。
没有任何反应。
I also tried with a @color
link but it crashed, with the background of a drawable (ex. android:background="@drawable/fab_background")
nothing happens.
这是可绘制的 fab_background.xml
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<ripple android:color="@color/fab_color_1_muted">
<item>
<shape>
<solid android:color="@color/fab_color_1" />
</shape>
</item>
</ripple>
</item>
推荐答案
使用
app:backgroundTint="@android:color/holo_green_dark"
(例如)设置工厂的颜色。结果如下。 来自经过测试的代码段。
(for example) to set color of fab. Result below. Taken from this -tested- code snippet.
还可以编辑:奇怪的绿色应该来自您的强调色。这是彩色工厂默认情况下采用的颜色。
Also edit : "strange green color" should come from your accent color. That's the color fab takes by default.
