形状可绘制为背景,一个线在底部 [英] Shape drawable as background, a line at the bottom
问题描述
我使用的是绘制作为一个TextView的背景只是有文字下方的分隔线。一个与此绘制-XML achivied它:
I am using a drawable as a background of a TextView just to have a divider line below the text. A achivied it with this drawable-xml:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape
android:shape="rectangle">
<solid android:color="#FFDDDDDD" />
<gradient
android:angle="0"
android:startColor="#FFAAAAAA"
android:endColor="#FFEEEEEE"
/>
</shape>
</item>
<item android:bottom="2dp">
<shape
android:shape="rectangle">
<solid android:color="#FF000000" />
</shape>
</item>
</layer-list>
但这种方法绘制一个黑色的矩形上方的彩色矩形。我想刚才的线形状,没有黑色矩形底部,因为黑色是不是透明的。我怎么能做到这一点?
But this method draws a colored rectangle above a black rectangle. I would like to have just the line at the bottom of the shape with no black rectangle because black is not transparent. How could I achieve that?
推荐答案
在一般情况下,我尝试一塌糊涂尽可能少与背景,除非绝对必要的,因为这样做会覆盖默认的背景色为国家为重点,pressed,等我建议只使用一个额外的视图(在垂直的LinearLayout),你需要它是厚。例如:
In general, I try to mess as little as possible with backgrounds unless absolutely necessary, since doing so overrides the default background colors that have states for focused, pressed, etc. I suggest just using an additional view (in a vertical LinearLayout) that is as thick as you need it to be. For example:
<View
android:background="#FF000000"
android:layout_height="2dp"
android:layout_width="fill_parent"/>
