你的问题有所不同，或者你无法解释，但我得到了它

1. 克里特在drawable，bottom_selected和bottom_unselected
中有两个文件

Bottom_selected.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

    <item>
        <shape android:shape="rectangle" >
            <solid android:color="#001EFF" />
        </shape>
    </item>
    <item android:bottom="3dp">
        <shape android:shape="rectangle" >
            <solid android:color="#FFFFFF" />
        </shape>
    </item>

</layer-list>

Bottom_unselected.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

    <item>
        <shape android:shape="rectangle" >
            <solid android:color="#001EFF" />
        </shape>
    </item>
    <item android:bottom="1dp">
        <shape android:shape="rectangle" >
            <solid android:color="#FFFFFF" />
        </shape>
    </item>

</layer-list>

现在你的按钮

 <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_below="@+id/fragment_container"
        android:layout_marginLeft="54dp"
        android:layout_marginTop="110dp"
        android:background="@drawable/bottom_selected"
        android:text="Button" />

    <Button
        android:id="@+id/Button01"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBaseline="@+id/button1"
        android:layout_alignBottom="@+id/button1"
        android:layout_toRightOf="@+id/button1"
        android:background="@drawable/bottom_unselected"
        android:text="Button" />

    <Button
        android:id="@+id/Button02"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBaseline="@+id/Button01"
        android:layout_alignBottom="@+id/Button01"
        android:layout_toRightOf="@+id/Button01"
        android:background="@drawable/bottom_unselected"
        android:text="Button" />

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
  android:shape="rectangle">
  <gradient android:startColor="#FFFFFF" 
    android:endColor="#FFFFFF"
    android:angle="270" />

</shape>

Answer 3

代码 -

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <!--Minus (-) how much dp you gave in the stroke width from left right top-->
    <item android:left="-10dp" android:right="-10dp" android:top="-10dp">
        <shape
            android:shape="rectangle">
            <stroke
                android:width="10dp"
                android:color="@android:color/holo_red_dark" />
            <!--This is the main background -->
            <solid android:color="#FFDDDDDD" />
        </shape>
    </item>
</layer-list>
