为Android视图钻石形状xml背景

Question

嗨大家请建议我如何创建android xml drawable像下面的图像？

现在我使用以下代码

<?xml version="1.0" encoding="utf-8"?> 
<layer-list xmlns:android="http://schemas.android.com/apk/res/android"> 
    <item> 
     <rotate 
      android:fromDegrees="45" 
      android:pivotX="-40%" 
      android:pivotY="87%" 
      android:toDegrees="45"> 
      <shape android:shape="rectangle"> 
       <stroke 
        android:width="10dp" 
        android:color="@color/colorAccent" /> 
       <solid android:color="@color/colorAccent" /> 
      </shape> 
     </rotate> 
    </item> 
</layer-list> 

但其结果是三角形，但我需要上述形状。

检查这一点，

<?xml version="1.0" encoding="utf-8"?> 
<layer-list xmlns:android="http://schemas.android.com/apk/res/android"> 
<item 
    android:left="43dp" 
    android:top="43dp" 
    android:right="43dp" 
    android:bottom="43dp"> 
    <rotate android:fromDegrees="45"> 
     <shape> 
      <size 
       android:width="200dp" 
       android:height="200dp" /> 
      <gradient 
       android:startColor="#0fdcc9" 
       android:endColor="#0fdcc9" /> 
      <stroke 
       android:width="5dp" 
       android:color="#2DACA0" /> 
     </shape> 
    </rotate> 
</item>

我固定在本教程 here

<?xml version="1.0" encoding="utf-8"?> 
<layer-list xmlns:android="http://schemas.android.com/apk/res/android"> 
    <item 
     android:bottom="43dp" 
     android:left="43dp" 
     android:right="43dp" 
     android:state_pressed="true" 
     android:top="43dp"> 
     <rotate android:fromDegrees="45"> 
      <shape> 
       <size 
        android:width="200dp" 
        android:height="200dp" /> 
       <gradient 
        android:endColor="@color/colorPrimaryDark" 
        android:startColor="@color/colorPrimaryDark" /> 

       <stroke 
        android:width="5dp" 
        android:color="@color/colorPrimary" /> 
       <corners android:radius="7dp" /> 
       <padding 
        android:bottom="10dp" 
        android:left="10dp" 
        android:right="10dp" 
        android:top="10dp" /> 
      </shape> 
     </rotate> 
    </item> 
</layer-list>

这是我的钻石形状绘制文件ic_diamond.xml文件。

<?xml version="1.0" encoding="utf-8"?> 
<vector xmlns:android="http://schemas.android.com/apk/res/android" 
android:width="372.7dp" 
android:height="367.4dp" 
android:viewportWidth="372.7" 
android:viewportHeight="367.4"> 

<path 
    android:fillColor="#50AE89" 
    android:strokeColor="#266D4F" 
    android:strokeWidth="5" 
    android:strokeMiterLimit="10" 
    android:pathData="M188.706,51.8702 L318.105,181.269 L183.968,315.406 L54.5691,186.007 
        L188.706,51.8702 Z" /> 
</vector> 

我包括这在简单视图：

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

在这里，是结果：
