圆内边方形布局边境 [英] Square shaped layout border with round inside edges

问题描述

我正在试图创建具有角是上内侧向外侧和圆方布局的边界。我收集了，我需要创建两个形状组成一个xml绘制的定义：一个具有描边宽度和圆角半径，另一只用笔画宽度：

I’m attempting to create a layout border with corners that are square on the outside and round on the inside. I’ve gathered that I need to create an xml drawable definition composed of two shapes: one with a stroke width and corner radius and another with a stroke width only:

可绘制/

round_border.xml

round_border.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <stroke android:width="4dp" android:color="#FF000000" />
    <padding android:left="7dp" android:top="7dp"
            android:right="7dp" android:bottom="7dp" />
    <corners android:radius="4dp" />
    <solid android:color="#FFC0C0C0" />
</shape> 

square_border.xml

square_border.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <stroke android:width="2dp" android:color="#FF000000" />
    <solid android:color="#FFC0C0C0" />
</shape> 

每个这些作品independantly为界，当appliedby本身就像这样：

Each of these works independantly as a border when appliedby itself like so:

安卓背景=@可绘制/ round_border但是当他们一方或双方被添加到项目列表绘制如下所示：

android:background="@drawable/round_border" but when they either or both are added to an item-list drawable like so:

composite_border.xml

composite_border.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <layer-list>
        <item android:drawable="@drawable/round_border"/>
        <!-- <item android:drawable="@drawable/square_border"/> -->
    </layer-list>
</shape> 

和

安卓背景=@可绘制/ composite_border

android:background="@drawable/composite_border"

布局的背景是全黑的，而不是只是一个黑色的边框 - 任何人都知道如何使图层列表的工作完成这个任务。

The layout's background is completely black instead of just a black border - anyone know how to make the layer list work for this task?

推荐答案

创建一个XML文件

像round_background.xml

<?xml version="1.0" encoding="utf-8"?>
<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">
   <solid 
       android:color="#CCCC33"/>
   <size 
       android:width="35dp"
        android:height="35dp"/>
</shape>

在布局设置为背景

    <LinearLayout
                android:id="@+id/layout_wellbeing"
                android:layout_width="wrap_content"
                android:layout_height="match_parent"
                android:layout_weight="1"
                android:gravity="center"
                android:background="@drawable/rounded_corner_leuvan"
                android:orientation="horizontal" >
 </LinearLayout>
