自定义 Spinner 使其看起来像一个按钮

Question

我有一个定义如下的自定义按钮

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:state_pressed="true" >
        <shape android:shape="rectangle"  >
            <corners android:radius="10dp" />
            <stroke android:width="1dip" android:color="@color/colorPrimary" />
            <gradient android:angle="-90" android:startColor="@color/colorPrimaryDark" android:endColor="@color/colorAccent"  />
        </shape>
    </item>
    <item android:state_focused="true">
        <shape android:shape="rectangle"  >
            <corners android:radius="10dp" />
            <stroke android:width="1dip" android:color="@color/colorPrimary" />
            <solid android:color="@color/colorAccent"/>
        </shape>
    </item>
    <item >
        <shape android:shape="rectangle"  >
            <corners android:radius="10dp" />
            <stroke android:width="1dip" android:color="@color/colorPrimary" />
            <gradient android:angle="-90" android:startColor="@color/colorPrimary" android:endColor="@color/colorPrimaryDark"  />
        </shape>
    </item>
</selector>

我想创建一个微调器，它在未被单击时看起来像按钮，只有在按下时才显示可选择的项目。默认的微调器不是很漂亮，不符合我的设计。

有人知道如何实现吗？

                            <Spinner
                            android:id="@+id/spinner_start_day_def"
                            android:layout_width="100dp"
                            android:layout_height="30dp"
                            android:layout_gravity="center"
                            android:background="@drawable/rounded_button"
                            android:gravity="center"
                            android:minWidth="70dp"
                            android:popupBackground="@color/colorPrimary"
                            android:textAlignment="center" />

这很简单，android:background="@drawable/rounded_button"
