我在创建使用XML简单的圆角矩形的麻烦。每次我尝试的角落元素添加到自定义形状，我得到：

I'm having trouble creating a simple rounded rectangle using XML. Every time I try to add the "corners" element to the custom shape I get:

java.lang.UnsupportedOperationException     在   android.graphics.Path.addRoundRect（Path.java:514）     在   android.graphics.drawable.GradientDrawable.draw（GradientDrawable.java:314）     在   android.view.View.draw（View.java:6520）           ......

java.lang.UnsupportedOperationException at android.graphics.Path.addRoundRect(Path.java:514) at android.graphics.drawable.GradientDrawable.draw(GradientDrawable.java:314) at android.view.View.draw(View.java:6520) ...

RES / dawable / rounded_rectangle.xml：

res/dawable/rounded_rectangle.xml:

 <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle"> 
        <solid android:color="#ffffff"/>    

        <stroke android:width="3dp"
                android:color="#ff000000"/>

        <padding android:left="1dp"
                 android:top="1dp"
                 android:right="1dp"
                 android:bottom="1dp"/> 

        <corners android:bottomRightRadius="7dp" android:bottomLeftRadius="7dp" 
         android:topLeftRadius="7dp" android:topRightRadius="7dp"/> 
    </shape>

使用上述形状简单layout.xml：

simple layout.xml using the above shape:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_height="fill_parent" 
    android:layout_width="fill_parent">

<View android:id="@+id/View01" 
    android:background="@drawable/rounded_rectangle" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent">
</View>
</RelativeLayout>

据透露，我试图编译为Android 2.1，我已经安装到Eclipse所有最新的更新和Android SDK。这种形状的东西，我看到了在其他网站上直接拷贝，但由于某种原因它不想为我工作。

Fyi, I'm trying to compile for Android 2.1 and I have all the latest updates installed to Eclipse and the Android SDK. This shape is a direct copy of something I saw on another website, but for some reason It doesn't want to work for me.

感谢。

推荐答案

所以，我只是在摆弄这一点，我换了几行，在rounded_rectangle.xml得到它的工作。请看下图：

So, I was just playing around with this a bit and I changed a couple of lines in the rounded_rectangle.xml to get it working. See below:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle"> 
    <solid android:color="#ffffff"/>    

    <stroke android:width="3dp"
            android:color="#ff000000"/>

    <padding android:left="1dp"
             android:top="1dp"
             android:right="1dp"
             android:bottom="1dp"/> 

    <corners android:radius="30dp"/> 
</shape>

我只希望谷歌将推出一个适当的参考文档，用于创建基于XML的形状。几个小时后（4+）追捕的例子在网络上的，我觉得它仍然是一个猜谜游戏，什么元素/属性在这些类型的XML文档的支持。很抱歉的小咆哮。

I only wish Google would put out a proper reference doc for creating XML-based shapes. After hours (4+) of hunting down examples on the Web, I feel like it's still a guessing game as to what elements/attributes are supported in these types of XML documents. Sorry for the mini-rant.

我希望这可以帮助别人。

I hope this helps someone else.
