android – 如何创建平行四边形的形状背景？

<layer-list  >
    <item>
        <rotate
            android:fromdegrees="10"
            android:todegrees="10"
            android:pivotX="-40%"
            android:pivotY="87%" >
            <shape
                android:shape="rectangle" >
                <stroke android:color="#000000" android:width="10dp"/>

            </shape>

        </rotate>

    </item>
</layer-list>

作为@ mmlooloo的回答的替代方案,我建议使用xml-drawable解决方案(因为你还没有强调你正在寻找什么样的解决方案).在下面的示例中,我使用了一般视图,但您可以使用任何其他视图.

这是视图

<View
    android:layout_width="100dp"
    android:layout_height="40dp"
    android:layout_centerInParent="true"
    android:BACkground="@drawable/shape" />

和shape.xml本身

<?xml version="1.0" encoding="UTF-8"?>
<layer-list xmlns:android="http://@R_607_10906@mas.android.com/apk/res/android" >

<!-- Colored rectangle-->
<item>
    <shape android:shape="rectangle">
        <size 
            android:width="100dp"
            android:height="40dp" />
        <solid android:color="#13a89e" />
    </shape>
</item>

<!-- This rectangle for the left side -->
<!-- Its color should be the same as layout's BACkground -->
<item
    android:right="100dp"
    android:left="-100dp"
    android:top="-100dp"
    android:bottom="-100dp">
    <rotate
        android:fromdegrees="45">
        <shape android:shape="rectangle">
            <solid android:color="#ffffff" />
        </shape>
    </rotate>
</item>

<!-- This rectangle for the right side -->
<!-- their color should be the same as layout's BACkground -->
<item
    android:right="-100dp"
    android:left="100dp"
    android:top="-100dp"
    android:bottom="-100dp">
    <rotate
        android:fromdegrees="45">
        <shape android:shape="rectangle">
            <solid android:color="#ffffff" />
        </shape>
    </rotate>
</item>

</layer-list>

它是这样的：
