如何只从元件的一侧删除边框？ [英] How to remove border only from one side of the element?

问题描述

我有：

<stroke android:width="1px" android:color="#A6ACB1"/>

我想从元件的底部（例如）删除此边框。可能吗？ （Eclipse的只是建议我：颜色，宽度，dashWidth和dashGap）。

I'd like to remove this border from the bottom (for example) of the element. Is it possible? (Eclipse suggests me only: color, width, dashWidth and dashGap).

推荐答案

据我所知，还没有这样做的一个简单的方法。但如果使用图层列表与具有边框上，然后一个不与从您想要的边框等于边框的宽度，你的所有边抵消项目实现这一目标。

As far as I understand it, there isn't an easy way of doing it. but if you use layer-list with an item that has the border and then one that doesn't with an offset from all the sides for which you want a border equal to the border width, you'd achieve that.

请允许我向XML为你重新presenting无边框底部。

Let me make the xml for you representing the borderless bottom..

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <!-- Border -->
    <item>
        <shape>
            <solid android:color="#f000"></solid>
        </shape>
    </item>
    <!-- Body -->
    <item android:left="2dip"
          android:top="2dp"
          android:right="2dp">
        <shape>
            <solid android:color="#ffafafaf"></solid>
        </shape> 
    </item>
</layer-list>

正如你所看到的，我说的是第二项底部，除了各方面（因此底部的无边框结果）被镶嵌第一个由两个DP的，你去那里：

As you can see, I'm telling the second item to be inset of the first one by two dp's on all sides except bottom (hence the no-border result on the bottom), there you go:

所以基本上这是不是每本身的边界，它是从波纹管的形状（但如果你需要虚线或点，或任何你可以添加一个边框）所覆盖的第二个项目将是按钮的身体。位于同一抽拉：）

So essentially this isn't a border per-se, it's the shape from bellow (although you could add a border if you need dashed or dotted or whatever) being covered by a second item with would be the body of the button. All in the same drawable :)

这可以应用到你要删除的任何边界，通过改变该项目是插图，例如，如果我改变其值右键在车身项目以底，缺少的边框会，因为它是正确的是一个没有插入

This can be applied to any border you want to remove, by changing the values that the item is inset, for example, if I change the right in the Body item to bottom, the missing border would the right one since it's the one without the inset
